In 2005 precision stamper Weiss-Aug of East Hanover, N.J., achieved a reject rate of less than 1 part per million. The company credits the success to meticulous planning and almost flawless execution. Such an approach applies for Weiss-Aug even when it comes to uncoiling metal.

A die transport system may be needed if current production requirements cannot be met with existing presses, and opportunities for additional contracts are limited by current equipment production volumes; parts can be produced competitively in large batches, but not if the part count is smaller; and shop safety needs to be improved.

Cosma International applies its own hot-forming technique to stamping automotive metal components such as A and B pillars, roof headers, roof rails, rockers, door intrusion beams, and bumpers, to meet new CAFE standards for weight, NHTSA requirements for strength, and to counter problems with springback in UHSS components.

Draw forming is one of the net shape processes, and, as a result, many of the technology advances in the general field of manufacturing have not been as beneficial to draw forming as one would expect. All too often, such advancements as lean manufacturing, statistical process control, just-in-time, and six sigma, have not resulted in benefits for draw forming.

Problems that can arise during metal slitting include poor edge quality, edge burr, edge wave, camber, crossbow, knife marks, and slit width that is out of specification. Some slitting problems can be attributed to poor metal quality; however, it is much more common for the problems to be caused by other variables and factors during the slitting process.

Major technology shifts in how stamping presses are fed have allowed press feed technology to evolve, enabling stampers to realize increased processing speeds, improved processing flexibility, easier setup, and better quality and reliability. Even with today's advancements, a press feed must meet three basic and important criteria to be successful: Setup must be flexible. It must deliver the material with sufficient precision into the tool and die. It must feed at the correct time. Advancements in feed technology include pilot release, space-saving line configurations, transfer/progressive operations, and scratch-free processing.

Stampers face increasing pressure, from external and internal customers, every day. This, combined with increasing responsibilities, can cause production personnel to feel overwhelmed. Long die changeovers gobble up precious time that could be used for better purposes, leaving many production teams operating in a firefighting mode. Doing a thorough time study and using the results to eliminate time-wasting steps is the first step in implementing quick die change, freeing up some time for value-added activities, and getting control over your production processes.

A slitting line can operate efficiently for 20 or more years if properly maintained. Modern slitting lines are high-performance machines that are intended to produce 24 hours a day, 365 days a year. As a result, stampers must be sure that all line elements are properly maintained, which represents a titanic effort if you don't understand what components are critical.
