Answer» Answer: PVC pipes are manufactured by extrusion of raw material PVC, and generally follow the same steps of typical pipe extrusion operations: Feeding of raw material pellets / powder into the PVC twin screw extruder. Melting and heating in multiple extruder zones. Extruding through a die to shape into a pipe. Most manufacturing environments fit into one of five general CATEGORIES: Repetitive, Discrete, JOB Shop, Process (batch), and Process (continuous). In the diagram below, each letter represents a different PRODUCT. "White space" indicates set-up, tear-down, or a changeover activity of some type. Explanation: Manufacturing Process Plastic extrusion: Plastic is heated and pushed through a heated chamber by a screw. Molding: Plastic is FORCED through a die that creates the final shape of the part. Cooling: The extruded plastic is COOLED. Cut or spool: The continuous shape is spooled or cut into lengths. |
