Collapsible Core Mold Solutions
for Complex Internal Undercuts
Collapsible core molds provide an innovative and highly efficient solution for molding plastic components with complex internal geometries. By collapsing inward before ejection, these cores eliminate the need for complex and space-consuming stripping mechanisms. Below, explore our successful case studies utilizing collapsible core technology for both round and rectangular plastic parts.
Collapsible Cores for Tubular & Round Plastic Parts
Ideal for components requiring internal circular grooves or internal threads. Compared to bulky mechanical unscrewing setups, collapsible cores take up significantly less space within the mold base. This allows for higher cavitation in smaller machines.
Collapsible Cores for Rectangular Plastic Parts
Ideal for rectangular enclosures and parts featuring internal undercuts on all four sides.
While tailored for different shapes, rectangular collapsible cores operate on the exact same fundamental principles as our round cores. Instead of radial segments, the mechanism utilizes precisely machined square or rectangular slider blocks that collapse inward simultaneously, smoothly releasing the internal undercuts on all four interior walls.
