12 Inserts, 1 Perfect Motion — How the Collapsing Core Achieves Full Synchronization In this mold, we use a 12-segment collapsible core structure, where each insert forms part of the circular geometry.Through an internal synchronized slide linkage mechanism, all inserts expand and retract simultaneously. During mold opening, the slide drives all inserts to expand outward evenly. During mold closing, each insert returns precisely into position to recreate the full circular geometry.This ensures s

A collapsible core mold is designed to form internal undercuts and complex internal geometries that cannot be released by standard mold structures. By collapsing inward during the demolding process, the core allows smooth part ejection while maintaining precise internal dimensions and surface quality. High-quality collapsible core molds require precise mechanical design, tight tolerance control, and high-precision machining to ensure stable movement and long service life. This solution is widely
