Difference Between Injection Molding and Extrusion .

While other forms of molding use extrusion to get the plastic resins into a mold, this process extrudes the melted plastic directly into a die. The die shape, not a mold, determines the shape of the final product. Extrusion molding involves forcing melted plastic through a die into a shape with a fixed cross section.Plastic Injection Molding and Extruding: Plastic Injection molding is simple with the right equipment. All that you need is a heater and some plastic. Recycled plastics will yield the best results if kept to their respective groupings. Refer to the recycle symbols and do not mix type.
