Slug retention machine includes design changes

September 12, 2013

DTC Products has introduced a new version of its patented slug retention machine. The device uses a pneumatically powered grinder to machine a small, angled groove into the side wall of the die cavity in a stamping die, preventing slugs from pulling onto the die surface where they can damage the metal strip, the stamped part, or the stamping die.

Additions and changes to the original design of the device include one thumb screw to adjust the grinder height (replacing the previous four socket head cap screws), a plunger-style grinder head assembly (replacing the earlier turn knob to control the up and down movement), and a grinder head adjustable depth stop to control the grinder’s depth into the die cavity.

The grinder assembly is adjustable to three height positions, each 0.5 in. apart, enabling it to work with a variety of part thicknesses. Flex lights allow the operator to see into the cavity for improved visual inspection of the work area.
