Plastic is one of the most widely used materials in the world; and many of the parts made of plastics and other polymers have to be made to exacting specifications. If the parts do not meet these specifications, then they are utterly useless. In order to ensure precision manufacture of plastic and polymer products, injection moulding has replaced die cutter-style tools as the method of choice.
The reasons for this transition are several; one of the chief advantages of moulding machines over older machine tools for producing plastic parts is their high throughput. A moulding machine can produce thousands of precision-made plastic products daily with very little operator intervention, in any size, shape and color required.
Everywhere a person looks, it is possible to find something made or uses something made on one of these machines. They range from pieces on a child's toy to pieces of a car or computer. These just aren't pieces that humans can make on their own.
An injection mould consists of two parts a mould and an injector. Pellets of plastic or other polymers are fed into the injector through a hopper. Once they enter the injector, they are melted and injected into the mould. A ram or screw provides the force needed for the injection process, pushing the molten plastic or other material into the mould.
The plastic is forced into the mould using a screw or ram. The mould holds the material for a few seconds while it cools sufficiently to set; then the mould is opened either automatically or manually, with the finished part being ejected and the process repeating until the production run is finished.
The total daily output of one of these machines depends on two factors the size of the injection moulder and the size and complexity of the piece to be produced.
The moulds are generally made from aluminum or steel. They are made by machinists with precision machine tools so that they will meet the exact specifications. The reason that they are made from steel or aluminum is that they have to stand up to a great deal of use and they well encounter a lot of heat. That much use and the heat from the plastic could warp other moulds.
The duties of an injection moulding machine operator varies from machine to machine. In most cases, the operator needs to make sure that the hopper is full for their shift. In some cases, they will have to take the finished pieces out once ejected from the mould. The operator will also have to do spot quality checks to make sure that the pieces are being made correctly.
They may not seem glamorous to most of us, but injection moulding machines are vital to the production of many of the items we use very day. They are made in many different sizes and configurations and may be designed to produce either simple or complex products, but regardless, they are an indispensible part of modern industry and modern life.
