Collapsible Cores are used in the production of pieces moulded with continuous or interrupted cylindrical undercuts (such as threads or seals) and they replace the insertion of traditional move- ment pieces such as racks and toothed wheels that are cumbersome and subject to wear.
On the market you can find different types of flexible collapsible cores, while our cores are “mechanical” with the following advantages:
- Lower overall dimensions and better performance
- Cycle reduction
- In case of breaking of a sector in our collapsible core it is possible to replace the single damaged element (something not possible in other types).
