PLASTICS PROCESSES

Manufacturing of plastic parts can involve one or several of the following steps: Shaping operations - This involves transforming a polymer pellet, powder or resin into a final product or into a preform using extrusion or molding processes such as injection, compression molding or roto molding. Secondary shaping operation - Here a preform such as a parison or sheet is transformed into a final product using thermoforming or blow molding. Material removal - This type of operation involvesmaterial removal using machining operations, stamping, laser, drilling, etc. Joining operations - Here, two or more parts are assembled physically or by bonding or welding operations.
