Heavy Machinery Connector Pins | Scrap-Free Cold-Form | Manufacturer

Electropin produces connector pins in lead-free brass and stainless steel as standard material options, with other metals available depending on project requirements. Lead-free brass eliminates the need for leaded alloys commonly used in machined pin production, removing REACH and RoHS compliance concerns without sacrificing conductivity or mechanical performance.

Electropin offers four primary retention features: Star (which can expand pin diameter up to 50% greater than the wire stock), Tabs/Spline, Inscribed Square, and Flat. These features provide anti-rotation and high pull-out retention strength for press-fit into metal, post-insertion into molded plastic, and through-hole PCB mounting applications.

Yes. Because Electropin uses lead-free brass and stainless steel, no leaded alloys are required — unlike many machined pin manufacturers that rely on leaded brass for machinability. This means pins are inherently REACH and RoHS compliant, simplifying regulatory documentation for customers in automotive, medical, and electronics supply chains.

Electropin connector pins support three primary mounting methods: press-fit into metal housings, through-hole PCB mounting, and post-insertion into molded plastic parts. The pin design and retention feature selected are matched to the mounting method, ensuring optimal retention force and dimensional fit for each specific application.

When raw materials are available, Electropin can begin manufacturing and deliver a first batch of cold-formed pins in as little as two weeks. Subsequent batches are delivered on a customer-specified timeline, and production volume can be scaled dramatically when demand increases — reducing supply chain risk for high-volume OEM programs.

Electropin supplies cold-formed connector pins to automotive OEMs and Tier suppliers, farm equipment manufacturers, computer and electronics assemblers, medical device manufacturers, and PCB/circuit board producers. The same cold-form manufacturing platform serves all industries, with pin geometry, material, and retention feature customized per application requirements.
