Case Study: Delivering Cost-Savings for a Metal Stamped Part

Reduce the costs of the shaft piece and simplify the manufacturing process.

Minimize the assembly costs utilizing a more efficient method that meets quality and design standards.

The shaft component was currently being produced as a sintered metal piece to attain the correct form. This was a time consuming and costly process.
Ultra recommended manufacturing the shaft as a cold-headed piece going forward. This process would produce the shaft more quickly and at a significantly lower cost. The strength of the shaft would also be increased and eliminate fracturing issues during assembly.

With the shaft addressed, Ultra turned to solving the assembly challenges. The most effective solution was to design and build a new progressive stamping die to assemble the part consistently and meet the customer’s production demands.

FIRST, the lever component is metal stamped in our Minster 100-ton press.
SECOND, the shaft and lever components are assembled. The bowl feeders, shown below, orient and feed the shaft components into the progressive die for assembly with the lever components.

Experienced a 90% decrease in the cost of the shaft piece.

Lead times were improved with assembly operations now taking place in the stamping press.

Production increased to 4,800 parts per hour
