an opportunity to bring in larger parts. We wanted to outfit the press for future work, eying new business opportunities where we might need more stroke length than we need currently.”
“We also worked with Sangiacomo to discuss what part-size ranges we were seeing with our quotes, which also dictated the specs of the feed line,” adds Childers. “We were quoting a little thicker material than Sangiacomo was used to feeding, because we sometimes need to stamp short, thick washers, and other times large thin washers— quite a variety—and we try to accom- modate that whole mix. That’s what led to the decision to use a Universal Feed coil line.”
A Perfect Complement to a Lean Strategy
Wyan and Childers have found the press to fit perfectly into the facility’s drive to become lean, as it’s been busy conducting lean training for its asso- ciates, including instruction on quick die change. Along with staging dies and material for subsequent jobs in
the queue and equipping die carts with all of the tools needed for changeovers, the firm has prepared work instructions for changeovers. Changing out the 200- lb. die that runs on the Sangiacomo, “we can place the die in the press, set it up and have it running in 20 min.,” Wyan says.
“It’s a fun press to run,” he adds, “and we even can adjust the speed of the press while it runs, which proves
helpful when we’re trialing new dies. We can start at 80 strokes/min., for example, then bump it up to 85 or 90 and watch how it runs, then ramp it up to 120 or 140 strokes/min., then adjust it back down if we need to, should part-quality issues arise. How- ever, oftentimes the faster we run the cleaner the cut when we’re blanking. We’re within 0.001-in. repeatability with this press; the precision is there.” MF
