Fixed Caliper & Floating Caliper Mold – Brake Part High-precision Sealing and Defect Control
Brake caliper molds require ultra-high compactness and air tightness, Xinfeng Mold optimizes flow channel and sealing structure to meet automobile brake safety standards.
Floating caliper low pressure molds maintain 0.05 MPa constant pressure filling, with internal casting compactness reaching 99.3% and zero air leakage rate.
Fixed caliper differential pressure molds adopt fully sealed parting surface design, with vacuum leakage rate controlled below 0.01 Pa/s during production.
Caliper mold steel hardness is stabilized at 44–48 HRC, resisting thermal impact of frequent short-cycle brake part production.
Special curved surface exhaust grooves eliminate blind hole gas accumulation, reducing caliper internal pore defects to below 0.4%.
Mold temperature is precisely controlled at 300–340°C, ensuring uniform solidification of thick and thin wall transition areas of brake parts.
Caliper mold trial products require 100% hydraulic pressure resistance test to verify batch production qualification.
Ejection pin polishing treatment reduces caliper surface scratch rate to zero, meeting brake part appearance standards.
Cooling pipeline internal cleaning every 1600 cycles ensures stable temperature control for high-precision brake molds.
Most manufacturers ignore vacuum sealing detection, causing 29% of caliper casting air tightness unqualified problems.
Caliper mold precision standards are consistent with shock absorber fork molds, belonging to automobile safety component high-precision molds.
Differential pressure molds are preferred for high-end calipers, while ordinary models adopt low pressure casting process for cost balance.
