Mold Structure & Design Description

The Collapsible Core Mold Components are engineered to allow for the creation of undercuts and other complex geometries that cannot be easily achieved with traditional molding techniques. These parts are integrated into the mold to facilitate easy ejection of parts without damaging intricate features.
Key design considerations include:

• Collapsible core design that allows for the removal of parts with complex undercuts

• High-strength steel for improved wear resistance and durability

• Precise machining to ensure proper fit and alignment in mold cavities

• Corrosion resistance for long-term reliability in high-cycle molding

• Adjustable insert design for varying part geometries and mold configurations

These design features ensure smooth ejection, reliable mold function, and consistent part quality.
