Hot forming: Strong meets light

May 9, 2006 | By Kate Bachman

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, Part I

May 9, 2006 | By Edmund Herman

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.

How to avoid slit-in coil slitting problems

March 7, 2006 | By Al Zelt

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.

Understanding press feeds

February 7, 2006 | By Bruce Grant

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.

Feeling overwhelmed with pressures?

February 7, 2006 | By Michael P. Schollmeier

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.

Maintaining a slitting line

February 7, 2006 | By Flix Remrez

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.

Coil feed line considerations when stamping HSS

December 13, 2005 | By John Heuring

With its higher tensile and yield strengths, HSS is stronger at any given gauge than conventional "mild" steels. Initially, lighter-gauge HSS was used to replace heavier-gauge mild steel to reduce weight in many automotive parts, and this continues to be the most widely used application for HSS. However, as a new trend to run thicker and thicker gauges of HSS continues, stamping fabricators are evaluating their press feeding and coil handling equipment, as well as press tonnage capacities and die designs to ensure that these harder parts can be formed effectively. The dynamics of HSS have a bearing on feeding, straightening, and coil handling equipment.

Straight to the point

December 13, 2005 | By Brian Landry

The straightener, when set properly, removes the coil set, or curvature of the rolled material. If the machine is used or set incorrectly, the coil set can remain in the material, even after being struck in presses with capacities to hundreds of tons. This can cause a variety of problems: out-of-tolerance parts, difficult feed operations that can disrupt and slow performance, and, to some extent, additional wear and tear on feed line components and tooling.
