Designing your part to take advantage of Automatic Die Rolling

The biggest consideration is that we cannot make large diameter changes. We can increase the diameter by stamping a “star”, which makes 4 locations around the pin higher; these are often used as insertion stops or when molded in as anti-rotation features. We can make a “collar” or “shoulder” around the diameter of the pin, but it is limited by the ability to raise material. Soft brass can be formed further than hard stainless steel.

In the picture to the right, you can see we stamped a star in the wire, then in the rolling die, rolled part of that star back down. The left side of the star is rolled back to wire diameter, leaving a sharp corner and flat edge to act as an insertion stop. On the right side of the star, we rolled that down, but not completely to wire size, making a part with 3 diameters, wire size, right side star diameter, and overall star diameter.

A Collaborative Process
for Custom Pins

Electropin will quote any pin design you have, but DFM experts are also ready to work with you to refine your designs. Simply tell us all the functionalities you need from your pin, and we’ll work with you to design a pin that performs and takes full advantage of the power of automatic die rolling technology. Electropin’s DFM team prides itself on its capacity for innovation, so the bigger your manufacturing challenge, the more we want to see your project.

A Collaborative Process for Custom Pins

The Cold-Forming
Process

Don’t know if cold-forming is the best manufacturing technique to meet your needs? That’s OK! We’ve developed this customized process to help you get the high-performing pins you need without sacrificing any functionality.

01

Step 1: Discuss Your Performance Needs

Meet with an Electropin DFM expert to tell us everything you need your custom connector pin to do and when you need your first delivery.

03

Step 3: Create a Die Mold

Electropin’s experts will create the tools needed to cold-form custom connector pins to your specifications.

02

Step 2: Refine
the Design

If cold-forming is feasible for your pin, an Electropin engineer will work with you to refine your design to achieve all the functionality you need at minimal cost.
