Product Description:

The guide bush is a precision component used in conjunction with a guide pillar to ensure accurate alignment and smooth movement between mold plates during the mold opening and closing process. It is typically made from high-quality alloy steel or bearing steel, and treated with heat treatment and precision grinding for high wear resistance, low friction, and long service life. Widely used in plastic injection molds, stamping dies, and other precision tooling systems.
