Mold Structure & Design Description

Mold core pins are installed on the core side of plastic injection molds to form internal features of molded parts.
Key design considerations include:

• Accurate pin diameter, length, and tip geometry

• Controlled concentricity relative to cavity inserts

• Proper fit with surrounding mold components

• Structural stability under injection pressure

All core pins are designed and manufactured strictly according to customer drawings to ensure correct mold assembly and stable production.
