Since its discovery, plastic has proven to have an amazing versatility which has made it among the most commonly used materials on earth. There are a great many different products made from plastics and other polymers, including parts which must be produced to very precise measurements and other specifications. Since meeting specifications is mission critical to manufacturers, cutting tools have largely been replaced by injection moulding machines.
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.
Everything from childrens toys to automotive parts and computer components are made using this method; what they all share is that it would be extremely difficult, if not impossible to produce by hand.
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 amount of pieces that can be produced in a day depends on the size of the machine as well as the size and complexity of the piece. This kind of moulding is good for making pieces that have a lot of nooks and crannies since they all get filled.
The moulds used in these processes are made from steel or aluminum using machine tools to achieve the necessary precision to meet the specifications demanded of the finished product. Moulds are made from strong, heat resistant materials in order to prevent them from warping under the heat and physical stress of the moulding process.
Injection moulding machine operators perform slightly different duties depending on the size and type of machine they operate as well as the procedures and workflow of the manufacturing facility where they work. Generally speaking, operators are responsible for keeping the hopper adequately filled. They will also usually perform spot checks for quality and depending on the machine they use, they may also be tasked with emptying the molds after the parts have set.
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.
