Collapse Core Molds - China

price: contact company for price

COLLAPSE CORE MOLDS China Collapse Core Molds Collapse Core Molds Conventional Custom Plastic Molds Collapsible core injection molding applies on plastic injection molding and extrusion, that is good for the parts what inner cavity dimension is bigger than outer dimension, it could demould quickly and successfully when injection and extrusion, such as pipe/fittings with collapsible, instrument shell, sealed gate.


Collapsible core technology characteristic: Ingenious structure, moving and demoulding in limited space

High precision and consistency for components

Cool machining technology for material with high hardness

Security & reliable mechanical structure for multi-cavities injection mold, and make the tooling size smaller.

The collapsible core having a straight pin improved stability of the collapsible core segments improving the dimensional accuracy of the molded part.

The pin diameter matches the inside diameter of the segments and by being contained by a stripper or containment ring matched to the outside of the segments the pin and the segmented sleeves are self-centering and extremely accurate.

Shorter and spring-loaded segments reduce the possibility of injection pressure opening the segments.

This reduces the time for injection and reduces cycle time.

The increased contact area between the pin and the collapsible core segments improves mold cooling allowing for faster cycle times.

The change of shape of the contact area between the segments and the pin, rounded surfaces moving across flat surfaces, reduces wear allowing for less maintenance.

WIT Mold supply all kinds of molds, such as conventional plastic molds, precision injection molding, unscrewing molds, two shot injection molds etc., and are mainly exported to North America, Europe and other parts of the world.
