Augur Metal Products, a sheet metal fabricator that manufactures components for OEMs, punches large stainless-steel sheets for commercial separators. Its punches required sharpening after punching 10 to 15 sheets until it changed to Mate punches made from DuraSteel™ tooling with Maxima® coating and dies made with Mate's Slug Free® design. The new tooling allows the company to exceed 40 sheets between sharpenings and increase press speed by 20 percent.

Custom metal fabricator Total Metal Products, Dallas, had a need for part marking that would be both accurate and cost-effective for small quantities. The company supplies punched parts in single and small-lot quantities of 200, 300, and 400 on a just-in-time (JIT) basis. Its customers include manufacturers in the telecommunications, aerospace, mass transit, and oil refining industries.

The author discusses what not to do to manage slug ejection. He mentions several tooling maintenance errors that he has made over the years, as well as what machine operators can do if they want to experience slug ejection difficulties. He concludes by stating that the easiest solution to slug management is to keep the tooling in good condition and to use the correct die clearance for the material.
