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

Forming options in the modern punch press grow in metalworking

Fab shops are realizing the flexibility of the modern punch press in greater numbers. They are turning to punching technology to improve workflow and lower their cost per part by handling more operations on one machine. This is particularly true for forming processes. The modern punch press makes it possible to bypass secondary operations and… Continue reading Forming options in the modern punch press grow in metalworking

What’s the Correct Reading?

I was recently contacted by a customer whose long-term supplier had manufactured a number of precision, hard-turned parts (0.4-0.8 Ra) inspected on the supplier’s CMM. Upon receipt of the parts, our customer used an air gage to verify the inspection results and found that more than half were outside of the specification. To verify the… Continue reading What’s the Correct Reading?

When metal fabricators and welders enter the “Twilight Zone”

We love to joke about the magic of welding. A shadowy shaman metal crafter takes your broken thing or pile of parts, disappears behind a mostly opaque curtail, says a spell, waves a wand, makes hellish noises. Poof! In a dissipating cloud of smoke, a welder reemerges, holding a finished product worthy of a response… Continue reading When metal fabricators and welders enter the “Twilight Zone”

Understanding Metal Stamping

Basic Concepts of Metal StampingMetal stamping, also referred to as pressing, is a low-cost high-speed manufacturing… Continue reading Understanding Metal Stamping

Stay with mechanical or go to servo? That’s the question for metal stampers

As manufacturing progresses through the 21st century, stamping manufacturers keep on searching for a better mousetrap that will help them be more efficient and effective today and in the future. When you are looking at purchasing a new press and are trying to decide between an eccentric-gear or link-drive mechanical press or a servo mechanical… Continue reading Stay with mechanical or go to servo? That’s the question for metal stampers

Die Science – Stamping Die Essentials: Determine the process first

Author’s Note: Since it’s been about 15 years since my Die Basics 101 series, I’ve been asked to write another series of articles on the fundamentals of stamping die design and construction. As experienced toolmakers and engineers retire, many companies have struggled to find and hire individuals with basic metal stamping tooling knowledge. I hope… Continue reading Die Science – Stamping Die Essentials: Determine the process first

Ask the Stamping Expert: How do metal formers stamp the unstampable?

Q: We have received a quote request from one of our largest customers for a high-volume, thin-gauge stainless steel part, but the feature sizes are too small to stamp for our comfort level. We’re afraid of the fragile punches and tiny die cavities that will be required in our tools, and the breakage, costly maintenance,… Continue reading Ask the Stamping Expert: How do metal formers stamp the unstampable?

Closing the Skills Gap With Sheet Metal Fabrication

New technologies are blurring the lines between CAD/CAM software and equipment to overcome training gaps, enabling more manufacturers to enter sheet metal fabrication. However, even with this technology, following best practices in part design is essential to ensuring that components function as intended. For instance, ensuring there’s enough space around features and providing manufacturers with… Continue reading Closing the Skills Gap With Sheet Metal Fabrication
