In the world of injection molding, having the right mold is crucial to producing high-quality plastic parts efficiently. One of the most versatile and widely used types is the Three-Piece Collapsible Mold, designed to simplify the demolding process for parts with undercuts or complex geometries.
A 3-Piece Collapsible Mold features a unique mechanism that allows the core of the mold to collapse after the part is formed, ensuring smooth removal without damaging the product. This innovation not only improves production efficiency but also reduces the risk of defects in intricate designs.

What is a Collapsible Core Mold?
A Collapsible Core Mold is a specialized injection mold equipped with movable cores that can retract or collapse during the ejection process. This type of mold is essential for creating hollow or undercut plastic parts, such as bottles, medical components, and cosmetic containers. By using a collapsible core, manufacturers can achieve high precision in complex parts that would otherwise be difficult or impossible to demold.
Advantages of Using a Three-Piece Collapsible Mold
Ease of Demolding: The collapsible core mechanism allows parts with deep undercuts or complex cavities to be removed effortlessly.
High Precision: Precision Collapsible Molds ensure tight tolerances and consistent quality across large production runs.
Cost Efficiency: Reducing part damage and scrap lowers overall production costs.
Versatility: Suitable for a variety of plastic materials and complex designs.
Durability: High-quality injection molds are built to withstand repeated cycles while maintaining accuracy.
Applications of Collapsible Molds
Automotive plastic components
Medical device parts
Cosmetic packaging containers
Hollow or intricate plastic products
Custom plastic parts for industrial applications
