Whether you're using a high-speed stamping press to make simple parts at breakneck speeds or doing something really tricky, like deep drawing a material that puts up a lot of resistance, the information in this technology area is sure to help. The articles, case studies, and press releases cover stamping presses, lubricants, and materials.

In deep drawing, if the contact angle between drawing stages is too large, cracks can appear and swelling can occur, resulting in scoring, curving, and imbalanced flange-lip roundness. Keeping the contact angle between 15 and 45 degrees is key to quality drawn parts.

Originally die protection was developed just to prevent damage to the tool and die during the operation of a stamping press. As sensor and controls technology knowledge has evolved and stampers knowledge of it has expanded, die protection technology has been expanded into other applications, such as increasing production rates and to perform quality assurance.

A Midwestern manufacturer sought to improve productivity on its nearly 10-year-old Verson transfer press. Although the press was in good condition, the original ETF transfer, which had endured 28 million press hits, was causing considerable maintenance costs and lost production. The stamper retrofitted the Verson transfer stamping press with a Schuler Automation AT series tri-axis transfer. This resulted in a 10- to 40-percent improvement in cycle times.

In the home appliance industry, designs are constantly updating to meet consumer tastes and changing market demands. For the stamping supplier forming a new bracket for a new design, high production volumes necessitated tripling the number of shifts. But tripling the number of shifts increased labor costs, as well as utility and material delivery costs. The stamper decreased the labor hours to resume a single-shift operation by implementing quick die change and magnetic die clamping.

When designing a part, you must decide which is the best way to form it. Should you draw it or stretch it? That depends on several factors, including forming depth.
