Injection molding machines are used for manufacturing parts from different plastics in a wide range of colors
shapes and sizes. Processing of thermosetting plastics involves transforming the initial material in the machine into a plastic state by heating it and injecting it under pressure into a closed shape (mold) and removing it from the mold after a cooling phase
