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...

Machining process: Machining is the process of cold working the metals into different shapes by using different types of machine tools. This process is mainly used to bring the metal objects produced by means of different fabrication techniques to final dimensions. Machining is accomplished with the use of machines known as machine tools. For production of variety of machined surfaces different types of machine tools have been developed. The kind of surface produced depends upon the shape of cutting, the path of the tool as it passes through the material or both. Depending on them metal cutting processes are called either turning of planning or boring or other operations performed by machine tools like lathe, shaper, planer, drill, miller, grinder etc. Classification of machining processes: Machining process are material removing operations in which the desired shape and surface finish on the finished product are obtained by removing surplus material. 1.
