Transfer Stamping Die For Brass Plumbing Fitting Bodies

The brass slugs enter the first station where they are squared and centered. Then the transfer fingers carry each part to the forming stations. Because the fingers hold the part firmly, the die can create deep hex shapes without the part slipping. The stations are spaced evenly, so the feed timing stays simple.

Thread forming is done with cold forming punches rather than cutting. This makes the threads stronger and leaves no chips inside the water passage. The punches are coated to resist wear from brass friction. A small air line blows any brass dust off the die face after each stroke, which keeps the guide rails clean.

The finished fitting drops through the last station into a collection bin under the press. The die has a built-in misfeed sensor slot, so the factory can add a sensor that stops the press if a part is not in the correct position. This protects the tool from double hits and broken punches.
