Mold Guide Bushing
A mold guide bushing is a precision alignment component used in injection molds, stamping dies, and tooling systems to ensure smooth and accurate movement between guide posts and mold plates. The mold guide bushing is manufactured with high-strength materials and precision machining processes to maintain tight tolerances, reduce friction, and provide stable guiding performance.
- Hardness: HRC 58-62
- Materials: SUJ2, S45C, 20CR
- Tolerance Accuracy: ±0.005mm
- Processing Technology: High-frequency/Carburizing heat treatment
- Customization: Standard sizes in stock, non-standard sizes can be customized
Product Description
Introduction
The mold guide bushing improves mold reliability and operational efficiency by reducing wear, enhancing alignment stability, and extending the service life of tooling systems. Compared with standard bushings, it offers better load distribution, smoother guiding motion, and reduced maintenance requirements during high-cycle production. This component is widely used in automotive mold manufacturing, electronics housing production, precision stamping, and plastic injection molding industries where accuracy, durability, and consistent output are essential.
Three Key Customization Aspects, Tailored to Your Needs
Ensure accurate movement and extend service life.
Precision Manufacturing, Excellent Quality
High Hardness
With strong stamping resistance, the guide bushings are made from SUJ2 material and undergo carburizing heat treatment, increasing hardness and enhancing wear resistance by 30%.
High Fit Precision
High-precision fit with guide posts,
The guide bushing and guide post feature high-precision sliding fit, with a fitting gap within ±0.005 on both sides. The tolerance is precise, offering excellent stamping resistance and wear resistance.
High Concentricity
High-precision fit with guide posts,
Concentricity within 0.01, with surface finish Ra 0.6-0.8. The high surface finish improves vertical alignment and enhances wear resistance.
High Precision
Precision tolerance of ±0.005mm, with internal and external diameter tolerance and runout within ±0.005mm. The precise tolerances ensure greater durability.
