Multi-Station Door Lock Progressive Die For High Volume Lock Cases

The strip travels through a drawing station that shapes the deep body of the lock case. Subsequent stations trim the flange and punch holes for the latch and cylinder with exact positions. Because everything is indexed in one die, the hole locations stay true relative to the case body, which is essential for smooth lock operation.
High-wear areas use carbide or coated tool steel inserts that can be replaced individually. This reduces the cost and time of reconditioning. The die also has built-in oil channels that lubricate the forming zones, lowering heat and friction at high stroking speeds.

After the final cut-off, the case falls onto a conveyor without needing a separate transfer system. This cuts labor and allows one press operator to oversee the entire output. For lock producers aiming at the residential and commercial security market, this progressive die is a smart capacity-building choice.
