Mould Core Pins

Mould core pins are precision components used to form internal features, holes, recesses and detailed geometry within injection-moulded parts. Because the finished moulded component is created directly around the core pin, dimensional accuracy and surface quality are critical to consistent production.

Core pins may be used in applications ranging from simple cylindrical features to complex mould geometries. Their design must take into account the moulded material, component geometry, operating conditions and the stresses experienced during repeated moulding cycles.
