Roehr's RT Series Collapsible Core, C-Core, is a major breakthrough for molding plastic parts requiring internal threads, undercuts, protrusions or cut-outs. The patented design incorporates only three moving parts, which utilize conventional mold movements.

In addition to being automatic in operation, the C-Core enables one to produce parts that, until now, have been considered impossible to mold. Parts with internal protrusions, dimples, interrupted threads and cutouts can now be economically produced on a high or low volume basis. Cycle time can decrease up to 30% when compared to unscrewing or other complex actuating mechanisms.

Full technical details, including basic stripper plate mold construction, core grinding and mold base machining dimensions are available in our downloadable Technical Data Book.
