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.

Q: How do I define the width of the metal stock required to stamp a part in a new progressive die? A: You need to consider a lot of factors when determining stock width for stamping a part in a progressive die. I assume your question on the stock width is so you can estimate the raw material...

Q: We have a large stamping tool running in a 300-ton press. A changeover tool makes a left part and a right part, each of which is about 0.1 in. thick and shaped like a peanut. One-half of the part (lengthwise) is coined offset one material thickness in depth in addition to a number of other...

To make the best use of servo technology, you must have the best practices, best people in place with ongoing training and support. The first step in getting more out of the servo press is understanding your current processes and their pain points; know your press's capabilities; and understand the critical tolerances for the part--and how servo presses can help overcome limitations.

Advanced high-strength steel (AHSS) materials are multiphase steels that contain martensite, bainite, and/or retained austenite. The use of AHSS materials in the automotive industry is increasing every day, because these steels provide strength and satisfy functional requirements at reduced weight....

Opinions on how to troubleshoot a stamping operation are not in short supply at any production stamping or die-building shop. I’m not trying to stereotype diemakers, designers, or technicians, but their decisions often are made based on insufficient data. Statistically speaking, if I...

Q: We recently received an order for domed spring washers stamped from 0.0010-inch-thick 301 1/2 hard stainless steel. The parts are about 0.250 in. OD and have two 0.006-in.-diameter pierced holes on a 0.150-in.-dia. circle centered on the part. We usually do not stamp anything less than 0.010 in....

Lubrication plays an important role in stamping, as it reduces friction at the tool-workpiece interface. Reducing that friction also reduces die and tool wear in large-volume production, which in turn increases tool life. It also allows smoother flow of the sheet material into the die cavity and...

Waukesha Metal Products, a metal fabricator and metal former based in Sussex, Wis., wasn't going to survive in the long run being a simple stamper of simple metal parts. It needed to reinvent itself and constantly look for ways to evolve if it were to grow and improve its chances of success in the face of more demanding customers. Its in-house knowledge and talent, investment in capacity, and contributions to the overall manufacturing cause are improving its long-term viability. They also have helped the company earn the 2015 Industry Award from The FABRICATOR.

Sometimes it’s the small items that make your workday easier. Standard die components with incremental improvements, such as roller cages with cylindrical rollers, and special gadgets, such as auto-indexing dimplers, can help smooth the stamping process and extend uptime.

Press monitoring systems improve overall equipment effectiveness (OEE) and help identify downtime culprits. Press controls track when the machine is running and when it is not. It counts machine cycles, and can detect both empty strokes and cycles when die protection or tonnage faults exist.
