Shock Absorber Fork Mold – Gravity Casting Process Optimization and Wear Resistance Upgrade

Shock absorber fork molds focus on wear resistance and dimensional stability, Xinfeng Mold optimizes gravity casting process to improve shock absorption part batch consistency.
Shock absorber fork gravity molds adopt step-type gating design, with filling speed controlled at 14–17 cm/s to avoid curved surface flow mark defects.
Mold cavity surface adopts high-precision polishing, with roughness controlled below Ra 1.2μm, reducing post-processing workload by 30%.
Mold steel after special thermal refining treatment has hardness of 42–47 HRC, supporting 105,000+ continuous production cycles.
Targeted exhaust structure at fork bending positions reduces cold shut defect rate to below 0.9% in seasonal temperature changes.
Mold preheating temperature is fixed at 310–350°C to eliminate internal residual stress of shock absorber structural parts.
Uniform cooling channel layout controls fork overall deformation within 0.12 mm, ensuring assembly matching accuracy.
Trial production of shock absorber fork molds requires 22 sample dimensional and appearance full inspection.
Quarterly mold surface hardening treatment extends service life by 20% for long-term mass production.
Many factories ignore bending position exhaust optimization, causing 33% of fork curved surface defect problems.
Shock absorber fork mold technology is compatible with motorcycle swingarm gravity molds in basic process parameters.
Gravity casting is the most cost-effective process for shock absorber fork mass production compared with low pressure schemes.
