Concept of mold and molding is quite popular in the plastic industries. Plastic has the advantageous features like high malleability, cheap in cost, high stability. So it is being used pervasively in molding. Basically Plastic injection molding is the main process for manufacturing plastic parts. Coming to the concept of molding, it is a process of manufacturing by which liquid or pliable new material get a rigid shape called a mold. In simple terms, plastic molding is a process where plastic is molded into the desired shape.
Injection molding has a great contribution in manufacturing so many domestic and industrial products. It is used to create many types of equipment like such as electronic housings, containers, bottle caps, automotive interiors, combs, and most other plastic products available today. The features like high tolerance precision, repeatability, large material selection, low labor cost, minimal scrap losses, and little need to finish parts after molding are the major advantages of the injection molding.
The plastic injection mold generally require followings in the process of plastic injection molding-
1. an injection molding machine2. raw plastic material3. A mold.
For manufacturing of plastic injections, there are various types of raw materials such as thermosetting plastic, elastomers and thermoplastic polymers (resins) etc are used for manufacturing of plastic injections as these materials have a greater viscosity. The plastic injection machines have basic component parts such as material hopper, heating unit, plunger etc. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part.
