What is an Injection Molding Machine? - Plastic4trade
Injection molding is an important industrial technique. Although it is somewhat similar to die casting, but the raw material used in this case are different. Die casting uses metals that melt at extremely high temperatures, whereas injection molding mostly uses glasses, elastomers, and most frequently thermoplastic and thermosetting polymers. Nevertheless, this process is commonly used to create thermoplastic materials. In this method, raw materials are heated to a certain temperature and then injected under pressure into the mould cavity without changing their composition.
