Engineering Overview:
The core challenge lies in the 360-degree internal undercut; JST Mould utilizes precision collapsible cores (缩柯) to allow for damage-free release. This eliminates the need for multi-part assembly, reducing potential leak paths and improving structural housing strength.
Technical Specifications & DFM Insights:
We optimized the collapsing sequence to prevent stress whitening on the internal sealing surface. The mold utilizes high-wear-resistant steel to maintain sharp parting lines on the curved geometry, ensuring a flash-free finish for airtight connections.
Why JST Mould?
We specialize in "impossible" ejection geometries. By integrating complex collapsible core technology, JST Mould helps Tier-1 clients achieve lower cycle times and superior part consistency for high-pressure applications.
Application Fields:
Automotive cooling systems, high-end HVAC plumbing, and industrial fluid transport connectors.
