Key Challenges & Solutions
Problem 1: Material Shrinkage Variations
- Issue: Dow material's low tensile strength led to tearing, so have to switched to Wacker 3011/50 (material self with black pigment) with 30% higher tensile strength.
- Solution: Redesigned mold core pin for Wacker 3011/50, because of different Material, different mold Shrinkage
Problem 2: Manual Demolding Inefficiency
- Issue: 300s cycle time with labor-intensive handling.
- Solution: Semi-automatic pneumatic fixture reduced cycle time to 120s and defect rate by 60%.Problem 3: Air Extraction Holes
- Issue: Air burrle on surface/Lack LSR material caused dimensional instability.
- Solution: Drill air extraction holes of the rear mold core.
4.Technical Points
✅ Precision Adaptation: Tolerance is according to ISO3302-1 Class M1 facing such complex Structure
