Step-by-step process for rebuilding a mechanical stamping press gearbox

Sometimes, when parts are not stamped properly, it’s not the die that’s at fault; it’s that the press has become out of square or alignment. Machining the bolster, bed plates, uprights, crowns, and gearboxes can get a worn press back to square. Although the bolster, bed plates, and uprights often can be machined on-site, the… Continue reading Step-by-step process for rebuilding a mechanical stamping press gearbox

The Four Slide Metal Stamping Advantage

Metal stamping is used to turn cold sheet metal and other materials — such as copper and brass — into high-performing products and parts that can be used in various industrial and manufacturing processes. Traditionally, power press stamping machines are built to blank and stamp metal parts; these machines are ideal for simple, straightforward operations.… Continue reading The Four Slide Metal Stamping Advantage

How metalworking manufacturers decide whether to fabricate or stamp

Metal fabrication job shops are the Swiss Army knives of manufacturers. Projects may walk in the door that are as varied as imaginable from the ones coming in the day before. “You never know what you’ll be asked to make,” fabricators typically say. “You have to be prepared for anything.” Certainly, metal fabricators competing with… Continue reading How metalworking manufacturers decide whether to fabricate or stamp

Design for stamping manufacturability begins with function

The process of stamping parts—from the initial request for quote (RFQ), through the tooling design/build process, and finally, to the stamping production—can be a long and winding road with a large gap between what is designed and what can be manufactured. A part designed with manufacturability in mind will run the smoothest, with the least… Continue reading Design for stamping manufacturability begins with function

Ask the Stamping Expert: How to calculate tonnage and force for swaging

Q: I am quoting a swaging application for a pitman arm part. The material is a bainitic microalloy steel forging with Brinell hardness from HB 229 to 285. We are trying to size the press for the swaging operation. How do I calculate the required tonnage and force? A: To answer your question, I first… Continue reading Ask the Stamping Expert: How to calculate tonnage and force for swaging

Reducing defects, improving ROI with direct-drive motors

Mechanical servo metal stamping presses use high-torque brushless motors to produce complicated stampings at fast speeds. But the type of motors used—traditional geared, chain drive system, or direct drive—can dramatically affect the final product. Modern stamping machines are highly sophisticated devices and can be a large capital investment. They give metal formers the ability to… Continue reading Reducing defects, improving ROI with direct-drive motors

What’s sizzling in hot stamping?

Stamping manufacturers using hot stamping technology to reduce vehicle weight, fuel consumption, and environmental impact fall into two categories, said Schuler Group Sales Manager Hot Forming Jens Aspacher. “First, there are the newcomers that are forced to step into this technology by their OEM customers. Second, there are manufacturers already hot stamping that face a… Continue reading What’s sizzling in hot stamping?

How stamping press controls have evolved to keep up with automation

Employee shortages and high turnover have made training important so that new employees—or those filling in for others—can adapt quickly to the challenges at hand … not to mention, the task flexibility required by supply chain disruptions. At the same time, press lines and tooling have become more automated with multiple interfaces that result in… Continue reading How stamping press controls have evolved to keep up with automation
