Unusual process in plastics
Unusual process in plastics Calender: To prepare sheets of material by applying pressure between two or more counter rotating rolls. Also the machine performing this process. Centrifugal Casting: A method of forming thermoplastic resins in which the granular resin is placed in a rota-table container, heated to a molten condition by the transfer of heat through the walls of the container, and rotated so that centrifugal force included will force the molten resin to conform to the configuration of the interior surface of the container.it is used to fabricated large diameter pipes and similar cylindrical items. Cold molding: Procedure in which a composition is shaped at room temperature and cured by subsequent baking. Drawing: The process of stretching a thermoplastic to reduce its cross sectional area, thus creating an orderly orientation of polymer chains with respect to each other. Embossing: Technique used to create depression of a sp...
