Automatic Die Rolling

Automatic die rolling is a cold-form manufacturing technique that doesn’t just minimize the problems of machining: it eliminates them. Thanks to this pioneering innovation, Electropin can deliver pins faster, less expensively, and more accurately than any other manufacturer.

How Automatic Die Rolling Works

Automatic die rolling is a manufacturing process in which raw material is pushed into a custom die and forced to conform to the shape of that die. Unlike machining, this technique generates no heat, produces no scrap, and requires no retooling. Instead, automatic die rolling generates five pins a second with an unbeatable defect rate.

Is Automatic Die
Rolling for Me?

If you’re only looking to make a few pins, automatic die rolling is not the right process for you. Similarly, if you require complex geometry for your pin, you may not be able to reap the technology’s benefits. For everyone else, however, automatic die rolling is the least expensive, most accurate, and fastest manufacturing process available.
Here’s why automatic die rolling is…



Machining can only produce a pin as fast as a blade can cut through metal. With cold-forming, you can get up to five pins a second.


Lowest Cost

With automatic die rolling, when you pay for five pounds of material, you get five pounds of pins. You also won’t have to worry about the regular (and costly) retooling that comes from machining.


More accurate

Because automatic die rolling tools don’t dull or change shape with heat, you can get an error rate of just one pin per 600,000,000. And no, that’s not a typo. No other method of making pins even comes close.
