Injection Molding Machine

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.

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.
