Copper Precision Mold Core Insert for Shampoo Plastic Bottle Cap Mold Parts
Product Overview

Our copper precision mold core inserts are engineered for shampoo plastic bottle cap mold applications, manufactured with exacting tolerances to ensure perfect fit and optimal performance in insert plates and mold cavities.

Manufacturing Excellence

During mold manufacturing, we maintain precise dimensional tolerances to ensure seamless integration with insert plates and mold cavities. Our advanced manufacturing technology and high-tolerance standards significantly reduce fitting time for mold masters.

  • Corner radius manufacturing with 0.2mm step in manual milling machines eliminates post-hardening grinding requirements
  • External dimension tolerance: +0/-0.015mm for smooth pocket fitting
  • Sprue bushing hole tolerance: H7 (0/+0.015mm)
  • Thread depth: 1.5-2 times thread diameter (M8 screw requires 12-16mm depth)
  • Ejector pin guidance: 15-20mm length for smooth ejection and extended lifespan
  • Ejector pin clearance: 1mm larger than pin diameter
