Our Technology

Automatic Die Rolling

Unlike machining, our cold-forming process pushes raw material through custom dies without cutting, heating, or removing material. The result: stronger pins, zero scrap, and consistent quality from part 1 to part 1,000,000.

No Cutting
Material flows into shape
No Heat
Cold-formed at room temp
No Tool Wear
Consistent across runs
REACH/RoHS

Retention Features

Every pin is cold-formed with precision retention features engineered for your specific application requirements.

Star retention feature on connector pin

Star

Highest retention and anti-rotational strength. Diameter up to 50% greater than wire. Ideal for circuit boards.

Spline tabs retention feature

Tabs / Spline

Strong retention with minimal diameter expansion. Best for post-insertion into molded plastic or pressed metal.

Inscribed square retention feature

Inscribed Square

Retention without protrusion. Ideal for high-speed automation where pins slide down tracks without orientation.

Flat retention feature

Flat

Maximum anti-pullout and anti-rotational force. Often oriented 90° from each other on opposite ends.

Product Range

12 pin types across 3 categories, all manufactured with zero waste using automatic die rolling.

How We Work

From your first call to production delivery, our process is built for speed and precision.

01

DFM Consultation

Share your pin requirements. Our engineers review your design and determine if cold-forming is the right fit, then optimize for manufacturability and cost.

02

Custom Die Creation

We build progressive dies in-house to cold-form your exact pin geometry. No outsourcing, no delays — complete control over your tooling.

03

Production & Delivery

First batches in as little as 2 weeks. At 5 pins per second with zero scrap, we scale from prototypes to millions on your timeline.
