脱螺纹机构，方便成型，模具结构简单，节省成型时间1/3以上。
Collapsible core demoulding technology is one of key technologies in moulds injection and extrusion, it applies for parts that 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. etc.

Technology characteristic:
1、Ingenious structure, moving and demoulding in limited space
2、High precision and consistency for components
3、Cool machining technology for material with high hardness
4、Security design: avoid damage moulds cavities and components when working
24 Cavity Collapsible Core Mold


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 reduces 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.
