As a specialty copper mill, our high quality extruded shapes, rods, and bars are produced from billets we cast in-house. As a leading producer of custom and standard shaped copper extrusions, EM carries an extensive tooling inventory consisting of several thousand dies. However, if custom tooling is necessary, you can rely on our seasoned toolmakers to produce all required extrusion and draw dies in-house.
