Product Description
Introduction
Rear Guide Pillar is a precision mold guiding component designed for rear-position alignment systems in injection molds, mold bases, stamping dies, and industrial tooling assemblies. Installed at the rear section of the mold structure, it helps maintain accurate positioning between moving plates and supporting components. Its reliable guiding function improves assembly stability, reduces misalignment, and contributes to smooth mold operation throughout repeated production cycles.
Manufactured from premium bearing steel such as SUJ2 or GCr15, the Rear Guide Pillar is processed through precision turning, heat treatment, cylindrical grinding, and polishing procedures. These manufacturing processes provide excellent hardness, dimensional accuracy, wear resistance, and long-term durability. The precision-finished surface ensures smooth interaction with matching guide bushings while minimizing friction and mechanical wear.
Rear Guide Pillars are widely used in automotive molds, plastic injection molds, stamping dies, mold bases, consumer electronics molds, medical device molds, and industrial automation tooling. Available in various diameters, lengths, and precision grades, they can satisfy both standard mold requirements and customized engineering projects. OEM and ODM services are available according to customer drawings and technical specifications.
