Custom Overmolding Mold High Precision Plastic Injection Overmolding Durable

Overmolding combines soft plastic or rubber with a hard substrate through secondary injection molding to create a single-piece product. This process significantly improves product comfort, wear resistance, and appearance, and is a highly efficient and commonly used process in modern plastics processing.

• Mold Structure Design: Determine the interface between hard and soft materials
• CAE Analysis: Verify melt flow and adhesion properties
• CNC Machining: Create high-precision mold cavities
• Mold Assembly: Install locating pins and cooling system
• Mold Trial Inspection: Test the adhesion strength and dimensional accuracy of the secondary overmolding

• One-piece molding reduces assembly steps
• Improves product anti-slip properties and comfort
• Beautiful surface, wear-resistant and durable
• Suitable for high-volume and stable production

• Q1: What products are suitable for overmolding?

  A1: Suitable for plastic parts requiring anti-slip properties, aesthetics, or dual-material structures.

• Q2: What is the precision of the overmolding mold?

  A2: Up to ±0.015mm.
