We specialize in the CNC machining and manufacturing of various stainless steel precision mold guide bushings, guide components, and sliding parts. We are committed to providing core stainless steel guide bushing components with extremely high dimensional accuracy, excellent wear resistance, good fatigue strength, and long-term operational reliability for precision stamping dies, injection molds, die-casting molds, and automated guiding systems.
As a core guiding element in precision molds, ensuring precise mold closing between the moving and fixed molds and guaranteeing forming accuracy, the mold guide bushing's fit clearance, surface hardness, and dimensional stability directly determine the mold's service life and product quality. Stainless steel guide bushings, especially those made of materials such as 440C and 17-4PH, offer excellent corrosion resistance (avoiding rust caused by cooling water or environmental humidity), good wear resistance, and sufficient rigidity, making them an ideal replacement for traditional bearing steel guide bushings.
Stainless steel mold guide bushing Trustworthy- Precision CNC machining
II. We provide full-process engineering services, from guide scheme design, material selection, process development, prototype manufacturing to mass production. Our engineering team is proficient in the performance requirements and processing technology of various mold guide bushings:
1. Multi-type stainless steel guide bushing processing capability
Straight guide bushing: Standard cylindrical guide bushing, used for general mold guidance
Shoulder guide bushing: With flange shoulder structure, easy to install, position and axial fixation
Oil groove guide bushing: Helical or straight oil grooves machined in the inner hole for self-lubrication
Sliding guide bushing: Cooperates with guide pillars for precision sliding guidance
Ball guide bushing: Inner hole with ball retainer for rolling guidance and lower friction coefficient
Custom non-standard guide bushings: Custom-made various irregular guide bushings and guide components according to customer drawings
2. Precise matching of materials and applications
High wear-resistant stainless steel guide bushings 440C, 9Cr18Mo: Martensitic stainless steel, high hardness HRC obtained through vacuum quenching + low temperature tempering. 58-62, suitable for precision molds with high load and high wear resistance requirements.
High-strength corrosion-resistant guide bushing 17-4PH: Precipitation hardening stainless steel, achieving ultra-high strength and good toughness through aging treatment, while also possessing excellent corrosion resistance, suitable for injection molds, medical molds, and other applications requiring high corrosion resistance.
General-purpose stainless steel guide bushing 420J2: After heat treatment, the hardness can reach HRC 50-55, offering high cost-effectiveness and suitable for general working conditions.
III. One-stop precision manufacturing and performance enhancement services for stainless steel guide bushings
We have built a complete manufacturing chain for stainless steel guide bushings with high precision and high wear resistance requirements, focusing on achieving a balance between precision fit and long service life:
Precision datum machining uses high-precision CNC lathes to precisely turn the guide bushing blank, completing the machining of the outer diameter, end face, and steps in a single clamping, establishing precise and unified process datums to ensure coaxiality and perpendicularity in subsequent machining.
