Properties, Comparisons, & Benefits Choosing Tool Steels—Balancing Toughness, Wear Resistance, & Compressive Strength Tool steels refer to a variety of carbon and alloy steels that are well-suited and widely used to make tools primarily used for perforating...
Solutions for punch wear, breakage, and other problems come from both time-tested techniques (e.g., adding a larger-than-normal radius under the head) as well as consideration for a wide range of leading-edge engineering solutions (e.g., head alterations) and...
Economic shortcuts in the build process almost always add to production costs in the form of increased maintenance and production scrap. To avoid these costs, initial concerns should be directed toward the type of die construction. Elements such as the stripper...
This report defines basic stamping terminology and illustrates basic stamping functions. We explore the common types of die construction, compare stripper design options, and analyze common die operations. Download PDF
Punch-to-die Clearance: What Works & What Doesn’t? Punch-to-die clearance (Δ) is the space between the cutting edge of the punch and the cutting edge of the die button, which is determined by the thickness and the type of material being punched. Optimizing...
The key to increased productivity Perforating punch to matrix (die) clearances in metal stamping dies have been universally expressed as a percentage of stock thickness, and for clarity should be expressed as percent per side. The old “rule of thumb”...
