Excessive press downtime between jobs is stamping’s perennial albatross around the neck. To expose the culprits in your shop, try scrutinizing every step in a coil handling system, from the coil itself to the material pilot guides in the tool.

An effective PM for dies can't happen without a skilled, engaged workforce. When it comes to uncovering ideas on how to improve a process, workers are the experts.
Most stampers don’t think twice about running a hydraulic press like it has been run for the last 20 years. By doing so, they are losing out on dramatic cost savings associated with a possible energy-saving retrofit that’s centered around a smart variable-speed pump drive.

To realize the importance of a good die preventive maintenance program, all a stamper has to do is recall the last time a press line shut down because of a major die problem. The downtime and reaction of the frustrated customer likely are hard to forget. The associated costs, however, aren’t typically documented. That shouldn’t be the case, because those costs can be very important in trying to convince management that a robust tooling maintenance program is worth every cent invested in it.

: Do you have the right below-the-hook lifting equipment for your material handling needs? Not many metal formers ask themselves that question, but they probably should, especially if they are concerned about eliminating possible coil damage and keeping employees safe.

Designing a production system that produces at a rate that matches customer demand can reduce waste. Right-sized equipment is sized to match customer demand, eliminating the waste associated with overproduction.

In general, troubleshooting of in-die fastening should focuses on four key aspects: the fasteners, the feed system, the in-die tools, and the control system

To stamp out the hidden costs of stamping lubrication, first keep everything consistent. Second, apply it right. Third, don’t forget disposal. And fourth, get lubricant to the press efficiently.

Not all metal forming jobs are done off the coil, so what can stampers do to ensure that the metal is level? They can use a stand-alone hydraulic roller leveler to ensure parts meet original specs.

The ranks within the tool and die community have thinned with the shop closures and business consolidations that followed the Great Recession. As a result, the depth of knowledge about tooling coatings has decreased as well in recent years. This primer is intended to provide a quick explanation of the most common tooling coatings for those that need a quick education.
While stampers struggle with traditional forming of aluminum alloys, particularly in the automotive industry, they should know that research is currently underway to make this tough job easier. Warm forming of certain aluminum alloys is a real possibility when it comes to stamping parts from these difficult-to-work-with materials.

Traditional mechanical presses remain dominant in industry, but sales of servo presses have gone into high gear in recent years. Controlling the press stroke turns out to have many advantages, and the technology’s adopters are reaping the benefits.
Boiled down, quick-die change covers all activities that occur between one job and the next. QDC boils down to reducing those activities by eliminating them altogether, making those remaining activties more efficient, and changing when those tasks are performed.

The days of 1 million unit orders for simple metal blanks are over. But this doesn't mean that stamping can't survive in today's manufacturing environment. A.T. Wall Co. believes it can successfully position stamping as a go-to manufacturing process for parts that were at one time exclusively made through machining.

Two new tooling steels can help stampers improve production efficiency. The metal formers just need to open their minds to the new possibilities.
