The word “extrude” means “to force out,” and that is precisely what happens during plastic extrusion. extrusion is a method by which molten plastic or any other material is pushed through a two-dimensional die opening. Keeping with the aesthetic theme, a third reason for using surface finishes is to mask any wear-and-tear that may arise from product shipping or other supply chain processes. This process consists of a few standard steps: A parison (a preheated hollow tube made of plastic) is fitted onto the blowing head of the machine and then placed inside of the mould. An injection moulding machine consists of a material hopper, a plunger and a heating barrel. As the plastic fills the mold, it takes on the shape of that mold.
