Customization of Rubber Molds for Auto Parts - High-Precision Solutions & Service Details

Core Pain Points: Industry Challenges in Rubber Molds for Auto Parts

New energy vehicle and traditional automakers have stringent requirements for rubber part molds, commonly facing three major issues: insufficient precision leading to seal leakage (failure occurs when tolerance exceeds ±0.02mm), short mold lifespan (ordinary molds only last 100,000-200,000 cycles), and delayed delivery cycles that lag behind vehicle model iteration rhythms (8-12 weeks on average in the industry), seriously hindering production capacity release.

Problem Analysis: Root Cause Lies in Disconnection Between Standards and Processes

Verified through practical operations, the core of the problem stems from three aspects: first, failure to adapt to international mold standards (such as HASCO, MISUMI) resulting in poor part compatibility; second, mismatched material selection with rubber properties leading to insufficient wear and temperature resistance; third, lack of digital design tools causing high mold trial repetition rate and prolonged T1 testing cycle.

Customized Solutions: Full-Link Standardized Implementation

1. Design and Standard System

Supports standards including DEM, HASCO, MISUMI, and Modepao. Accepts drawing formats such as STP, STEP, X_T, DWG, and DXF. Adopts NX, CAD, PROE, and SOLIDWORKS for modeling, combined with MOLDFLOW simulation to avoid warpage and shrinkage in advance.

2. Precise Material Matching

3. Delivery and Testing Specifications

Standard molds are delivered within 30-45 days, and complex parts within 60 days; T1 testing is completed in 3-5 days, including dimensional accuracy and demolding stability verification. Packaging adopts export-standard wooden cases, with EXW terms. Supports supporting injection molding of rubber materials (silicone, fluororubber, nitrile rubber).

Implementation Results: Dual Improvement in Efficiency and Quality

Through the standardized solution, mold precision is controlled within ±0.01mm with Ra≤0.2μm, suitable for core auto parts such as engine oil seals and shock pads; mold lifespan is 2-3 times longer than the industry average, with a customer mold trial pass rate of 98%, helping automakers shorten the new vehicle model iteration cycle by 30%.
