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
✅ Flame Resistance: UL94-V0 certification ensures safety in high-risk environments.
✅ LSR with Color: Seamless black pigment integration without machine contamination.
✅ Cost Efficiency: 32 cavities + robotic demolding cut per-part cost by 35%.

5.Industry Applications
- Automotive Electronics: EV battery connectors, sensor housings.
- Industrial Equipment: Flame-resistant seals for control panels.
- Consumer Electronics: High-durability USB/HDMI ports.
