Design & Manufacturing of Progressive Die with Nut Insert

A customer in the automotive industry contracted A-G Tool & Die, a division of Seilkop Industries, Inc. to design and manufacture a progressive die that would incorporate a nut into a stamped part, thereby eliminating a secondary operation that welded the nut to the part. Working with the customer, our experienced designers were able to develop a concept and design a tool that would make a part to our customer's specifications. Using our in house software, we were able to simulate the entire process and were able to recommend changes that would make the part more formable. After the customer apporved the changes and the die design, we quickly started machining operations. Programmers and CNC machinists processed the various details through machining cells that were developed through our Lean initiative that streamlined the milling, grinding and EDM operations. Die sets, parallels, and hot roll burnouts, were supplied by our sister company, Hamilton Precision LLC. The die was then carefully assembled, set in our press, and adjusted to make a quality part which was inspected on our CMM to verify that the part was dimensionally accurate.

Dimensions of the completed part was 6” in length, 4” in width, and a height of 2”. The tightest tolerance of ± 0.003” was held throughout fabrication. This is an unconventional product for this industry. This part was a challenge for many die shops, a challenge that Seilkop has the substantial experience and technical ability to accept without issue. Turnaround time for this unit was 18 weeks, producing 200,000 parts annually.
