Guide Pins and Guide Bushes
Product Introduction: High-Quality Mold Guide Pins and Guide Bushes
In the guide system of plastic molds and stamping molds, Guide Pins and Guide Bushes are core components that ensure mold alignment accuracy and prevent eccentric wear during opening and closing. As a mold manufacturer that produces for our own use, we maintain extremely stringent standards for wear resistance, concentricity, and surface finish of guide pins and bushes. Every set undergoes precision screening to ensure smooth, stable, and stick-free operation during long-term high-frequency movement.
Self-Produced and Self-Used, Rigorously Selected
We are not only a supplier of mold components but also a mold producer ourselves. Through extensive practical experience in our own molds, we have repeatedly validated the material, hardness, surface treatment, and fit clearance of guide pins and bushes. Only those with stable performance and exceptional durability are approved for our supply system.
Premium Materials, Precision Machining
Guide pins are manufactured from SUJ2 bearing steel or SKD61 heat-resistant steel, carburized and hardened to a surface hardness of HRC58-62. Guide bushes are made from wear-resistant copper alloy or steel-backed copper alloy with graphite inserts, combining high strength with self-lubricating properties. Precision grinding ensures that pin roundness and bushing inner diameter tolerances are controlled to micron levels.
Perfect Fit, Smooth Movement
We strictly control the fit clearance between guide pins and bushes to ensure stable, wobble-free mold opening and closing. This effectively protects the core and cavity from lateral forces, extending the overall lifespan of the mold.
Complete Specifications, Customized Solutions
For standard specifications, we maintain regular inventory of common diameters, lengths, and mounting types to support quick dispatch. For non-standard customization, based on your mold structure requirements, we offer custom guide pins and bushes with various materials, dimensions, oil groove patterns, and self-lubricating designs, with fast turnaround times.
We Can Also Source for You
If you have requirements for guide pins, guide bushes, or other mold components, whether standard or non-standard, we can leverage our production experience and supply chain resources to select and procure the most suitable parts for you. We know molds, and we know components.
