Question

which process is used to manufacture platic pipes

​

Answer 1

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.

Answer 2

Pipes are first and foremost produced through an extrusion process. ... Inside the extruder barrel the material is heated up to the melting point around 200°C by electricity and the friction in the screw system. The melted material is pushed through a cavity, called a die-head and thereby formed into a pipe.
