  • Why the annealing process is crucial for plastics GMN

     · Annealing is a secondary operation specifically a heat treatment and isn t typically done for all plastics parts or even in most plastic industries but it is an important technology here at Elite Plastics. This is an important step of the molding process because most plastic materials are poor conductors of heat which can lead to part damage.
