5 pitfalls to avoid when implementing SMED

July 5, 2011

By:

Single-minute exchange of dies is a lean manufacturing concept that has grown beyond the world of metal forming. It now stands for any lean exercise that attempts to reduce changeover time to single-digit minutes. In implementing such a program, manufacturing managers need to understand the common pitfalls that plague these efforts.

4 steps to press transfer efficiency

May 9, 2011

By:

Part-holding tooling is a fraction of the total press cost, but it has the most effect on whether a stamping press is running at its peak potential. Taking proactive steps in tooling selection, including working with your supplier, using simulation, choosing the best framework material, and choosing the most suitable end-of-arm tooling, can make all the difference.

The importance of the contact angle in deep drawing

February 25, 2011

By:

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.

Demystifying die protection

November 1, 2010

By:

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.

Tier stamper improves mechanical press productivity with transfer retrofit

September 10, 2010

By:

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.
