The trim die is a tool that trims the runner, overflows, and flash
from the casting. The trim dies are single or multiple cavity tools, made in
the same configuration as the die casting die.
Depending on the shape of the
casting, the trim die may be a simple open-and-close trim die or it may include
as many slides as the die casting tool. In some cases multiple station trim
dies will be used for successive trimming operations.
Trim dies require as much attention to detail
in design as the die casting tools and the use of quality materials should be
specified to extend their productive life.
