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.
