Product Description
Introduction
Inner and Outer Guide Post is a precision guiding component system designed for stamping dies, injection molds, mold bases, and industrial tooling assemblies. By combining internal and external guiding structures, it provides enhanced alignment accuracy and stable movement throughout mold opening and closing operations. This dual-guidance design helps reduce positioning errors, improve tooling stability, and support consistent production quality in demanding manufacturing environments.
Manufactured from premium bearing steel such as SUJ2 or GCr15, the Inner and Outer Guide Post undergoes precision machining, heat treatment, grinding, and polishing processes. These manufacturing methods ensure excellent hardness, wear resistance, dimensional stability, and surface smoothness. The guide posts work together with matching guide bushings to reduce friction, improve movement accuracy, and maintain long-term guiding performance under continuous operating conditions.
Inner and Outer Guide Posts are widely used in progressive dies, stamping molds, automotive tooling, precision plastic molds, electronic component molds, and custom mold base systems. Available in multiple diameters, lengths, and installation configurations, they can meet the requirements of both standard and customized tooling projects. OEM manufacturing and non-standard customization services are available according to customer drawings and technical specifications.
