Mold Structure & Design Description

Metric core pins with cooling systems are installed on the core side of injection or die casting molds to form internal product features while assisting heat dissipation.
Key design considerations include:

• Alignment between external pin geometry and internal cooling channels

• Controlled concentricity for reliable mold assembly

• Effective coolant flow for temperature regulation

• Structural strength to withstand injection pressure

All components are designed and manufactured strictly according to customer drawings to ensure correct assembly and stable mold operation.
