    Extrusion molding involves forcing melted plastic through a die into a shape with a fixed cross section. It’s an efficient way to produce many shapes. Since the plastic is melted from a solid form and then resolidified, only thermoplastics can undergo extrusion. The extruded part is cooled and can be cut or rolled for shipment.
