Cast Nylon is a synthetic polymer made by mixing the raw material of Nylon6 with a catalyst, polymerized and molded under atmospheric pressure. It has excellent mechanical properties, self- lubricating, abrasion resistance, chemical resistance and corrosion resistance. It is an excellent material that can be used to replace metal parts in various industry. Different additives can also be added to further improve its mechanical properties, such as OIL and MOS2.
