Extrusion Molding Extrusion is a process used to create objects of a fixed cross-sectional profile. designed in the specific shape of the desired product, forced through a custom die and cut to the requested lengths. Common types of extrusions are o-ring, cord stock and rubber tubing. NEWAY produces the highest quality extrusions in wide variety of standard shapes and materials Plastic Extruded Parts : Nitrile, EPDM, Neoprene, Silicone, Nature Rubber, Foam Rubber and Fluoroelastomer as well as many other custom compounds. Advantages The two main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections, and to work materials that are brittle, because the material only encounters compressive and shear stresses. It also forms parts with an excellent surface finish.
