Unveiled at Fakuma 2002 was the HYX MOLD 820S with a 4000 kN clamping force, new
injection unit size of 3,200 and maximum shot capacity of 1,860 g polystyrene.

Need Plastic Molding Parts Manufacturing, go to our site page to know more, we provide you all of plastics solutions.

To a large extent, the customers’ desire to be able to rely on the well tried and tested HYX MOLD technology but with higher clamping forces has provided the impetus for the consistent expansion of the machine range over the last three years.

The HYX MOLD 630 S was successfully launched at Fakuma 1999 as the first example of the
large class machines. The launch of the HYX MOLD 720 S represented the second stage, which
ARBURG demonstrated for the first time at K ‘2001. And the success that the large class
machines have displayed so far shows beyond a shadow of a doubt that expansion of the machine
range was a move in the right direction.

It was at Fakuma that ARBURG set out to achieve higher clamping forces and it was here also
that it reached the goal it has been striving for, as the HYX MOLD 820 S made its world debut.

Impressive key data

In addition to the clamping force of 4,000 kN, other important key technical data of the large
HYX MOLD 820 S includes the new injection unit size of 3,200, the maximum shot capacity of
1,860 g PS, the 820 mm distance between tie bars and the availability of 70, 80 and 90 mm
screw diameters.

As with their smaller counterparts, all the technical details that distinguish each and every
machine in the S series apply equally to the three large HYX MOLDS, the 630 S, 720 S and
820 S… proven modularity, energy-saving and rapid hydraulics systems, an easy-to-change
injection unit, as well as a powerful clamping unit guided on four tie bars with a rigid and stable,
moveable mould platen supported by long guide bushes.

Similarly, a variety of injection unit sizes can also be selected for the large class machines: the
1,300 and 2,100 series units can be used on all three and the new 3,200 series unit is available
for the 720 S and 820 S.

Special features of the large class machines

In addition to all this, the large class machines also possess detailed technical solutions, the
practical values of which have already been strikingly demonstrated by the HYX MOLD 630
S.

These features include mould height adjustment for variable mould sizes, connection to
temperature control circuits and core pulls using rapid connect couplings in close proximity to
the mould, the swivel-out feature of the injection unit, and injection control as standard.

As an option, an hydraulic accumulator can also be installed, greatly increasing the injection
flow of the injection unit.

The fully automatic mould height adjustment feature of the HYX MOLD 630 S, 720 S and
820 S allows the entire clamping unit to be adjusted to suit the required mould height. This
involves the distance between the fixed and the movable mould platen being adapted to large
differences in mould height by a drive unit on the support plate.

With the new HYX MOLD 820 S the maximum mould/ platen distance is infinitely adjustable
between 1,050 and 1,550mm and stroke can be programmed using the central SELOGICA control
system.

The advantages of this are lower energy consumption and a reduction in the cycle times, as the
stroke is now only required to open the mould and not to level out large mould height differences.

By incorporating this adjustment option, it was possible to render the large HYX MOLDs’
mould clamp construction more compact. Accessibility to the mould from the machine’s
operating side has been designed with spaciousness in mind.

Well provided for

The temperature control circuits are fixed securely to both clamping platens by means of rapid
connect couplings which can be extended if required. The advantages are a clearer overview and
improved safety, as well as faster accessibility. In turn, this means that the mould can also be
reconfigured more quickly.

The two manifold blocks for the mould are positioned behind the machine guard so that all of the
mould’s supply lines can be securely attached. The temperature can be set from outside of the
guard while the machine is operating.

The supply lines for the core pull systems are also connected to the moveable clamping platen,
using rapid connect couplings, meaning that all the supply connections are located directly on the plastic mould.

Large, but still easy to handle

As with the HYX MOLD 630 S and 720 S, the HYX MOLD 820 S is being presented with a
new size of injection unit, the 3,200 series. In this case too, the plasticising cylinder has been
designed as a module that can be easily changed despite its size.

In the area of the nozzle, the cover on the large HYX MOLDs consists of two sliding parts. The
unit has sufficient stroke to extend far enough away from the fixed platen to ensure that the
nozzle is easily accessible should there be the need for work in this area.

The plasticising cylinder can be located centrally and all electrical connections are
coupled/uncoupled automatically during installation and removal.

The entire injection unit is supported on a central, rotating turret to facilitate cleaning and
changing of the cylinder or the screw.

This means that once the injection unit has been retracted and secured, it can be swivelled
forwards manually, allowing for the cylinder or screw to be removed without difficulty.

With the HYX MOLD 820S with 4,000 kN clamping force and maximum shot capacity of
1,860 gramme polystyrene, ARBURG successfully concludes its expansion of machines with
higher clamping forces.

New motto : MODULARITY ALLROUND
ARBURG is starting the year 2003 with a bang … with a focus on program modularity

“MODULARITY ALLROUND” is the new motto which will cover all the injection moulding
machine construction company’s activities from this year onwards. With the presentation of the
4,000 kN machine at last year’s Fakuma in Friedrichshafen the three-year expansion program
has now been successfully completed.

Future activities will now be grouped under the new motto “MODULARITY ALLROUND”. This
describes the central focus of the company philosophy …the development of the ARBURG product
range. This motto stands for the future of the company in particular, without neglecting the
tradition of the HYX MOLD injection moulding technology, as ARBURG products have always
be known for their modularity.

MODULARITY ALLROUND … on a global basis
Due to the global focus of the ARBURG communication activities, the new motto will be used in both the original German form …MODULARITY ALLROUND…and in its English translation.

A special logo in the company’s colours will be launched alongside the motto, which will
pictorially represent the fundamental idea of modularity in an image that is impressive yet
simple and eye-catching.

Modular HYX MOLD
The modularity of the HYX MOLD can be seen in a variety of respects. This allows the
customer to put together a machine from the modular machine range which is customised with
respect to clamping force, injection unit or screw diameter.

Furthermore, ARBURG also offers a variety of drive concepts…the HYX MOLD C ‘advance’
special model and the ALLDRIVE machine series, with which electric and hydraulic drives can be
combined on a modular basis.

Modular MULTILIFT
With its MULTILIFT product range, ARBURG provides robotic systems which, thanks to their
modular construction, allow both the machine and the application to be designed appropriately
and to be integrated into the standard SELOGICA user interface.

Modular applications
The new ARBURG motto also describes the numerous HYX MOLD fields of application such the
encapsulation of inserts, the processing of several components, LSR, thermosets, powdered
materials and also PET for manufacturing preforms…HYX MOLDs can be used on a modular
basis due to special equipment variants.

In this way ARBURG offers its customers MODULARITY ALLROUND with respect to its product
range, thus allowing customers to design and use the products tailor-made to their applications.

The “New Dimension” has been completed
A target which, under the motto “hyx The New Dimension”, was unswervingly pursued was the extension of the machine range to include clamping forces of up to 4,000 kN.

The motto of the previous years also stood for the extension of the MULTILIFT robotic systems
product range, the structured provision with respect to electric or hydraulic drive variants…the keywords being the HYX MOLD C ‘advance’ special model and the ALLDRIVE machine series with modular drive technology…as well as for the increase in production area with the
construction of ARBURG II.

ARBURG’s injection molding machines are renowned for their well tried and tested modularity. When it comes to the ALLROUNDER ALLDRIVE (A) series, the principle of modularity also applies to the drives.

The ALLROUNDER A offers the choice of combining the electric main axes with either electric or hydraulic auxiliary axes, depending on which solution is best suited to any specific application. 
The first example of the electric ALLDRIVE series is the ALLROUNDER 420 A 800-400. It has an 800 kN clamping force, 420 x 420 mm distance between tie bars, 400 series injection unit, screw diameters of 35, 40 and 45 mm as well as electric main axes and also an electrically driven five-point toggle system to provide the highest degree of positional accuracy. 
Following the successful introduction of the first ALLDRIVE machine, the series was expanded through modular drive technology to include larger clamping forces. As a result, at Fakuma 2003, which is being held from October 14 to 18 in Friedrichshafen/ Germany, the ALLROUNDER 420 A will for the first time be accompanied by its big brother, the ALLROUNDER 520 A with a clamping force of 1,600 kN.

The Good injection molding machine A concept

The main functions of the injection molding machine – opening and closing moulds, injection and dosing – have been designed with electric drives as the basic structure. The other movements such as ejection and moving the nozzle and mould functions can either be electric or hydraulic, depending on the operating requirements. 

The movement of the mould closing operation is initiated by rotation of the servomotor to the five-point toggle system via a threaded spindle. This has been specially configured to the dynamic behaviour of the electronic drive.

The injection and dosing movements are converted with high torque via a gear position and a threaded pinion. To operate the movements with optimised use of time and low maintenance, the spindles are equipped with a special cool lubrication system. This ensures a high level of efficiency with low service costs and the longest possible service life. 

The machine series are modular in design due to the choice of auxiliary axes with electric or hydraulic drive. In this way, for example, the eject function can be carried out electrically, extremely accurately and dynamically with a spindle, or it can be carried out conventionally (‘softly’) with a hydraulic cylinder.

The nozzle advance movement, which in essence has a contact force applying function for most applications, is mostly with hydraulics or it can also be carried out electrically.
In ARBURG’s view it is very important that core pulls and specific special movements on the plastic mold, which have previously been integrated hydraulically, continue to be optimally operated with hydraulics in the future. For this reason, a special energy-saving small-accumulator hydraulic system has been developed for the optional hydraulic auxiliary functions on the machine, which can be assembled and dismantled on a modular basis.

Regulation

The basic structure of the electric axes ensures that they are highly dynamic and location-and position-regulated. This produces a reproducible, pin-point procedural sequence. This is mainly used for application with absolute and relative positioning accuracy for the mould and ejection movements.

In this way, for example, stroke-dependent functions such as mould positions in connection with core pull, or final positions when unscrewing, can be achieved extremely accurately.

As all stroke positions are measured absolutely, it is not necessary to carry out a reference movement or set them to a reference point.

On the injection side, the positioning accuracy and the acceleration in conjunction with the position-regulated screw movement can lead to additional accuracy with the injection molded parts. During dosage, the effect of the electric drive can be seen in the accuracy and in the energy requirement. 

When viewed on an individual basis, the options and potential for the improvement described, in conjunction with the well-tried and tested SELOGICA control system, lead to added value in relation to parts production.

The opportunity to operate individual cycle stages simultaneously adds even more importance to the programming of the SELOGICA control system. The appropriate cycle symbols with their comprehensive logistic links are extremely clear and can be used to optimise the procedures.

The synergistic effects of the ALLROUNDER A

During the development of the ALLROUNDER 420 A a great deal of importance was placed on the synthesis between the most up-to-date drive technology and tried and tested injection moulding technology.

In this way the design of the clamping areas ensures continued use of existing moulds. Furthermore, the daily operational practice is taken into account owing to the modular nature and the option of connecting hydraulic core pulls onto the plastic molds.

Flexibility through modular construction

The concept of electrically driven main axes as the basis and the option of freely combinable electrically or hydraulically driven auxiliary axes integrates the advantages of both systems. 

The machines have sufficient hydraulic power at their disposal precisely where it is needed, and they have the highest level of electro-mechanical accuracy coupled with economic energy consumption wherever feasible for the production task.

This means that the ALLROUNDER A machines also represent extremely flexible production systems, which always allow the machines to be equipped within an optimum cost/benefit framework, while at the same time precisely adapting them to the prevailing production requirements.

Injection Molding Equipment

Injection molding equipment is equipment that is very important for the operation of injection molding machines. Indeed, all injection molding machines utilize injection molding equipment that includes a power source, injection unit, mold assembly, and clamping unit to perform the four stages of the process cycle.

injection molding equipment
injection molding equipment

One of injection molding equipments is injection unit. This injection molding equipment is responsible for both heating and injecting the material into the mold. The first part of this unit is the hopper, a large container into which the raw plastic is poured. The hopper has an open bottom, which allows the material to feed into the barrel that contains the mechanism for heating and injecting the material into the mold.

Another injection molding equipment is clamping unit. Prior to the injection of the molten plastic into the plastic mold, the two halves of the mold must first be securely closed by the clamping unit. The hydraulically powered clamping motor actuates clamping bars that push the moveable platen towards the stationary platen and exert sufficient force to keep the mold securely closed while the material is injected and subsequently cools. After the required cooling time, the mold is then opened by the clamping motor.

There are also molds, typically made of steel or aluminum, as the plastic injection mould and molding equipment. The mold has many components, but can be split into two halves. Each half is attached inside the injection molding machine and the rear half is allowed to slide so that the mold can be opened and closed along the mould’s parting line. The two main components of the mold are the mold core and the mold cavity.

When this injection molding equipment is closed, the space between the mold core and the mold cavity forms the part cavity that will be filled with molten plastic to create the desired part. Multiple-cavity molds are sometimes used, in which the two mold halves form several identical part cavities.

Mold base also includes injection molding equipment that is a place where the plastic mold core and cavity are each mounted. Then, the mold base is fixed to the platens inside the injection molding machine. The front half of the mold base includes a support plate, to which the mold cavity is attached, the sprue bushing, into which the material will flow from the nozzle, and a locating ring, in order to align the mold base with the nozzle.

The rear half of the mold base includes the ejection system, to which the mold core is attached, and a support plate. When the clamping unit separates the mold halves, the ejector bar actuates the ejection system. Meanwhile, mold channels are one of injection molding equipment types that is usually integrated into the mold design in order for the molten plastic to flow into the mold cavities.

First, the molten plastic enters the mold through the sprue. Additional channels, called runners, carry the molten plastic from the sprue to all of the cavities that must be filled. At the end of each runner, the molten plastic enters the cavity through a gate which directs the flow. The molten plastic that solidifies inside these runners is attached to the part and must be separated after the part has been ejected from the mold.

Besides using several types of injection molding equipment, there are many types of materials that may be used in the injection molding process. Most polymers may be used, including all thermoplastics, some thermosets, and some elastomers. When these materials are used in the Thermoplastic Injection Molding Process, their raw form is usually small pellets or a fine powder. Also, colourants may be added in the process to control the colour of the final part.

Plastic Injection Molding Process

Plastic injection molding process requires the use of an injection molding machine, raw plastic material, and a plastic mold. In this process, the plastic is melted in the injection molding machine and then injected into the plastic mold, where it cools and solidifies into the final part. Plastic injection molding process is getting popular today.

In this process, the plastic is melted in the injection molding machine and then injected into the plastic mold, where it cools and solidifies into the final part. Plastic injection molding process is getting popular today. Plastic injection molding process produces thin-walled plastic parts for a wide variety of applications. Injection molding is also used to produce several everyday items such as toothbrushes or small plastic toys. Many medical devices, including valves and syringes, are manufactured using injection molding as well. The following information will describe in greater detail of this plastic injection molding process. The first step of plastic injection molding process is the clamping of the mold. The clamping unit is one of three standard elements of the injection machine. They are the mold, the injection unit, and the clamping unit. The clamp is what really holds the mold while the melted plastic is being injected, the mold is held under pressure while the injected plastic is cooling. Injection molded parts that is used in plastic injection molding process can vary greatly in size and therefore require these measures to cover a very large range. As a result, injection molding machines are designed to each accommodate a small range of this larger spectrum of values. Injection molding machines have many components and are available in different configurations, including a horizontal configuration and a vertical configuration. On the other hand, regardless of their design, all injection molding machines utilize a power source, injection unit, mold assembly, and clamping unit to perform the four stages of the process cycle. Injection molding machines that can be used in plastic injection molding process are typically characterized by the tonnage of the clamp force they provide. The necessary clamp force is determined by the expected area of the parts in the mold and the pressure with which the material is injected. Thus, a larger part will require a larger clamping force. Also, certain materials that require high injection pressures may require higher tonnage machines. The size of the part must also comply with other machine specifications, such as shot capacity, clamp stroke, minimum mold thickness, and platen size. Next step of plastic injection molding process is the real injection of the plastic which is melted. The plastic regularly begins this process as pellets that are put into a large hopper. The pellets are then fed to a cylinder; here they are heated until they become molten plastic that is easily forced into the plastic mold. The plastic stays in the plastic mold, where it is being clamped under pressure until it cools. As with any process, there are advantages and disadvantages associated with plastic injection molding process. The advantages be more important than the disadvantages for most companies; they contain being able to keep up high levels of production, being able to reproduce a high tolerance level in the products being produced, and lower costs for labor as the bulk of the work is done by machine. Plastic injection molding also has the added benefit of lower scrap costs because the mold is so precisely made. However, the disadvantages of this plastic injection molding process can be a deal breaker for minor companies that would like to use plastic injection molding as a way to manufacture parts. These disadvantages are, that they equipment needed is expensive, therefore, increasing operating costs.

The Safety of Plastic Food Wraps

  • Plastic food Package Containers are used safely by millions of people every day to help protect foods against spoilage and contamination.
  • Some food wraps contain adipates, a kind of plastic softener that allows plastic wrap to cling to bowls to help keep food fresh and safe.
  • One of these adipates, called DEHA, has been the subject of inaccurate media reports recently. These stories ignored decades of safety studies showing that DEHA is safe in food wrap.
  • The U.S Food and Drug Administration, which ensures the safety of food packaging, carefully reviews studies on all substances before allowing their use in food packaging. Based on extensive research, the Food and Drug Administration permits the use of DEHA in packaging for all types of food.
  • Based on U.S. Department of Agriculture figures for average consumption, the exposure to DEHA is below levels of concern. A Consumer’s Union study alleged high exposures, but even assuming that the analysis was accurate, a 150-pound adult would need to eat more than 1,000 pounds of cheese in a single day to reach the observable effect level found in lab animal testing.
  • On its Internet website, Georgetown University’s Center for Food and Nutrition Policy (CFNP) recently wrote, “We at CFNP view the benefits of using plastic wrap to protect food safety and quality on the shelf to far outweigh the imagined risks ….” 

Plastics in the Microwave

Over the years, consumers have come to appreciate the important role plastics play in keeping food safe and healthful. In the home, plastic wraps, storage containers and sealable bags help keep your family safe and your food fresh and free of contamination.

What may be less clear is how appropriate these containers are for use in your microwave oven. Dr. Charles Breder, an expert on food packaging and former supervisory chemist at the U.S. Food and Drug Administration (FDA), offers these guidelines:

  • Cook or reheat foods in containers intended for microwave use. These containers are designed to withstand the high temperatures that are possible when the foods you’re heating contain fat or sugar.
  • Plastic Molding company can make plastic food package box and other type of plastic mold base on customer requirement
  • Remove food from store wrap before thawing or reheating in a microwave oven unless the manufacturer has indicated that it’s meant for microwave use. Some plastic trays, wraps or containers can melt or warp when the food gets hot, possibly causing spills and burns.
  • Most cold-food packages – such as margarine tubs, cottage cheese containers and foam meat trays – are not intended for microwave use.
  • Plastic wraps, placed loosely over bowls or dishes during rewarming, can help keep moisture in and provide even cooking. If the wrap touches the food, the wrap could get overly hot and possibly melt. Yet, as Dr. Breder notes, if you were to accidentally eat food containing melted plastic, you’ll likely have an unpleasant eating experience – but you won’t be harmed.

The gas assistant molding system

Gas assistant molding is a kind of new technology which brings the high-pressure air into plastic molding parts to let the plastic product with hollow section. Compare to traditional plastic molds​, it can reduce the weight of the product; realize thick wall and thin wall at the same time. The product surface will be more beautiful than traditional mould, without shrink mark, deformation and other molding defects. This kind of molding technology is more and more widely used in commodity products plastic injection moulds, household appliances product plastic injection moulds.

ST after some years’ research and development, it succeeds on gas assistance molding technology on various kinds product, such as for plastic chair, plastic handle and so on. Below is the picture of our design of a gas assistant chair for your reference.

Besides, injection machine and plastic injection mould, gas assistance equipment including Nitrogen Generator, pressure controller unit and air inlet parts.

RHCM (Rapid Heat Cycle Molding)

It is a kind of high speed and high-temperature molding technology. Put some Glass Fiber into plastic raw material to get the plastic product with high hardness and reflective surface. RHCM can remove the molding defects like melt line and flow mark which will appear in traditional plastic molding.

RHCM use high steam to make the mould cavity surface to reach the plastic raw material distortion temperature. Mould with high temperature ensures the good flow of plastic raw material; it makes the material fast flow and filled. It can avoid material to become more solid. This kind technology realizes no cooling molding and product with high glossy appearance without molding defects like deformation, melt line, flow mark, silver line. This kind of mould with short cycle time, reduce around 70% compared to traditional molding.

Plastic molds

RHCM mould have its advantage, it also have some disadvantages

  •  Mould steel will be easy crack
  •  Oil stain – As the mould temperature will be exceeding 130 ℃
  •  Gate area will appear white mark

Even though, RHCM technology is not widely used on market, but it will be a main technology in future as more and more customer require for high quality product, especially for outer parts. Nowadays, RHCM mould is mainly used in outer part product, like TV case and some automotive parts.​

Plastic Mold Making

To achieve the desired mold productivity, many elements of plastic mold making and design must be intelligently incorporated. The basics of design for plastic mold making must be the starting point and then added to that, decisions made about a whole host of different design options must be made to work in concert with the basics to come up with an optimized mold design.Plastic Mold

Everyone is interested in having the lowest cost tool, but in plastic mold making, other considerations must also be included. Among these is the mould’s ability to be readily maintained, and kept in optimum condition throughout the mould’s useful life. A very low initial cost tool may prove to have a larger overall cost of operation; if for instance, lengthy maintenance procedures are required to keep the tool in operational condition throughout its life.

There are two general types of cavity and core inserts that should be considered when plastic mould making: Integrated and Nested or Split Structure. Each has its advantages and disadvantages, so the decision about which to choose when plastic mold making depends on the application and the required useful life of the mold.

Plastic Mold China is speeding to the world today, to make your business more successful, find a China mold company is more important.

Integrated Cavity

The integrated cavity is cut directly into the mold base plates. It requires the fewest number of parts and is the simplest to produce, so often (though not always) this is the least expensive to produce in terms of initial investment. However, as stated, this is not always the least expensive alternative when considering the cost of the tool over the life of the part.

Some of the Advantages of Integrated Cavity Mold Making include:

• More practical for large or odd-shaped parts, such as automotive body panels and similarly shaped parts.

• Least amount of machining – so lower initial cost.

• Least amount of mold materials used – so lower materials cost.

Conversely, some of the Disadvantages of Integrated Cavity Mold Making include:

• Requires larger, more expensive machines to make the molds, and no components may be made in parallel, so they often have a longer lead time to produce.

• Most costly, difficult and longer lead time to modify in the event revisions are required.

• Costly and difficult to repair with longer down times when the mold wears or is damaged during its useful life.

Nested Cavity

When making a nested cavity plastic mold, cutouts are made in the mold base to receive nested parts that form the mold cavities that produce the finished parts. While this has more components than the Integrated Cavity type, often the advantages of plastic mold making using this method far outweigh the disadvantages.Plastic molds

Advantages to using Nested Cavity plastic molds making:

Complex geometries may be more easily formed when using nested cavities, for example, multi-pin electrical connectors are nearly always made with nested cavity tools.

Improved materials may be more easily incorporated into nested cavity molds for reduced wear and improved mold temperature control ability.

Damaged or worn components can be quickly and inexpensively replaced to minimize downtime.

Some of the disadvantages of using Nested Cavity plastic mold making include:

• Higher initial material costs

• More machining required in some cases, as both the mold base and the cavities require precision manufacture. (However, most of the machining may be performed on smaller, faster and less expensive machines.)

Precision Measurement And Injection Mold Making

It is remarkable that it is possible to open a package from Sweden, clean up EDM tool, and install it in an engine lathe spindle made in upstate New York, and indicate the run-out with a dial indicator made in Switzerland, held by a magnetic base made in Japan. This is amazing in itself, but the truly amazing thing is that it all works, quite well!

In this example, which actually happened to me, the run-out was less than .0001in/.0025 mm, right out of the box, first try. This is what precision tool measurement is all about.

The number of precision tools used by an injection mold maker are numerous. A partial list would include:

Precision measurement tools

  • Granite surface plate
  • Surface gage
  • Dial indicator
  • Height master/Cadillac gage
  • Gage blocks
  • Pin gages
  • Sine plate
  • Magnetic squaring block
  • Vee-block
  • Precision micrometers
  • Spin fixture

One of the more challenging aspects of building a mold is to have all of the various measuring tools calibrated to the same standard. This is why the EDM chuck from Sweden fit in the American lathe spindle: the accuracy was traceable to a common standard.

It doesn’t mean much if you are accurate within .0002 in., if your micrometer is off! It just won’t work. Shops need to have a master set of gage blocks that are traceable to the NIST, or National Institute of Standards and Technology. This is not as hard as it sounds, you just need to invest in a good set of gage blocks, not some made by child labor in a developing nation.

The proper care and use of these expensive tools is critical as well. They need to be treated with respect, handled carefully, kept free from rust and grinding grit. They need to have a clean storage place, with a grit-free surface on which to sit.

There are many places that you can cut costs in Plastic mold making, precision measurement tools is not one of them. It simply makes no sense to save money by buying a cheap dial indicator, for example. It is only going to haunt you in the long run. The same holds true for gage blocks, micrometers, squaring blocks, sine plates and so on.

With large items, such as the optical comparator or coordinate measuring machine, it is especially important to obtain a reliable tool. Valuable shop time can be quickly consumed with trouble-shooting a low quality machine. Not only that, but what if the measurements are unreliable? The mistakes can become extremely expensive and will quickly erase the initial savings.
