Today we will discuss plastic injection compression molding or moulding process step by step from jason mould.
Injection molding is a technique used in shaping different materials such as plastics, metals, glass, and sand. Just like everything else, there are different types of molding techniques with the main types being:
Injection
A thermoplastic is usually the raw material used in the process and mold is made of metal. To begin the molding process, the raw material is heated in a heating chamber and then injected into the mould.
It’s then allowed to stay in the mold chamber for sometime where it solidifies. When it solidifies it usually leaves parting lines and sprue lines. The parting lines are left on the final object where the parts of the object meet.
Sprue is the area where the raw material was injected in the mold. In most cases the raw material solidifies in the sprue hole and has to be broken off and as a result leaves marks on the final product.
Rotational
This process is used in creating hollow items that are made of plastic. The molding process begins with the pouring of the heated stock into the mold. The mold is then heated in an oven and rotated slowly in order to spread the stock evenly.
After doing this the mold is cooled and when it solidifies it’s removed. This technique is great as it makes it possible for one to create products of different thicknesses and designs.
