Product Description
Introduction
Inner Guide Pillar is a precision guiding component designed for stamping dies, progressive dies, mold bases, and precision tooling systems. Installed inside the die or mold assembly, it provides accurate internal guidance and positioning between moving plates, helping maintain alignment throughout repeated production cycles. Its compact design makes it particularly suitable for tooling systems that require precise movement control within limited installation space.
Manufactured from premium bearing steel such as SUJ2 or GCr15, the Inner Guide Pillar undergoes precision machining, heat treatment, grinding, and polishing processes to achieve outstanding hardness, dimensional accuracy, and wear resistance. The precision-ground surface ensures smooth engagement with guide bushings, reducing friction and supporting stable operation under continuous industrial conditions. Its hardened structure helps extend service life while maintaining reliable guiding performance.
Inner Guide Pillars are widely used in metal stamping dies, precision punch tools, progressive die systems, automotive molds, electronic component molds, and industrial tooling assemblies. Available in a variety of diameters, lengths, and tolerance grades, they can meet the requirements of both standard and custom mold structures. OEM manufacturing and non-standard customization services are available according to customer drawings and technical specifications.
