Bimetallic Cylinders


It is important that both extruder and injection cylinders are in good condition in order to maintain good productivity and a stable process. Many cylinders supplied by the OEM are nitride hardened but it is best to specify a high quality bimetalic alloy. Below are some of our common material options.
