Extrusion is a compressive forming manufacturing process that creates lengths of shaped cross-sections from metal billets. The process utilizes high force to squeeze the material through a shaped die and achieve the final desired shape and size. The die is made with a material with wear resistance and higher hot strength than that being extruded to ensure precise cross-sections and a smooth surface. As one of many compressive forming techniques for metals, extrusion is used for its manufacturing speed, relatively low cost, and resulting smooth finishes Specifications a.
