High-Precision Washer Stamping Metal Die For Fastener Supply

Coil strip feeds automatically into the washer stamping metal die. At the first station, a small punch cuts the center hole with a precise clearance. The strip advances, and a larger punch blanks the outer diameter, separating the washer completely. The scrap skeleton exits continuously, so no manual part removal interrupts the fast cycle.

We grind all punches and die buttons to tight tolerances, which produces a smooth shear face and keeps burrs small. Ball-bearing guide posts align the upper and lower halves perfectly, reducing punch wear. A simple lubrication of the strip before it enters the die is enough to protect the cutting edges and keep the operation clean.

The die runs in mechanical presses up to 45 tons and can be adapted for different washer sizes by swapping punch-and-die insert sets. Its sturdy build dampens vibration, which also helps keep noise lower on the shop floor. For fastener suppliers, this die means steady quality and high daily numbers without needing a dedicated operator at every press.
