141. The real plastic injection molding

When some people talk the plastic injection molding, we still think the process of the plastic injection molding is very difficult. But it is wrong. A variety of custom molds are manufactured using plastic molding process which varies from the smallest component to an entire body component.

The machinery involved in plastic injection molding is costlier and very sensitive and complex equipment. These machines are called as injection molding machines. The machines used are also heavy and some even weigh upto tons of kilogram. But only when these kinds of machines are used the final product turns out to be a quality product. This is so because the plastics are fed into these machines and they are heated until they become fluid.

The injection molding machine has two components namely the injection unit, the mold and the clamping unit. One should not forget that the process involved in plastic molding is not as tough as the size of the machinery. It is a very simple and a systematic process. Initially the injection molding process starts with the injection of the plastic resins or polymers into the injection barrel. The resins are heated to melting point and now the fluid is poured into the mold which is of the desired shape needed. The mold has two components namely the injection mold and the ejector mold. The melted plastic resin in poured into the mold using a sprue the injection mold. And the ejector mold helps in ejecting the plastic part after it is solidified in the mold without any damage using ejecting pins.

After the cooling process there is often change in the mechanical that is both physical and chemical properties of the plastic part. The thickness of the mold is one of the important design considerations of the injection molding process. Usually a mold with an uniform wall thickness is preferred. Thus it reduces the change in mechanical properties of the plastic molds.
