Minicore®

Roehr's Minicores broaden the applications of collapsible core molds to parts as small as 0.425 inch. Due to the smaller diameters involved, these Minicores employ three larger collapsing segments combined with three narrow, non-collapsing blades which are part of the center pin. As a result, up to 80% full threads or undercuts can be molded.

In addition to threads, other configurations such as dimples, cut-outs or protrusions beyond the capabilities of unscrewing molds can be successfully molded. Three standard sizes of minicores are available with diameters from 0.425 to 0.965 inch.

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