Founded in 1943 as Autoswage Products, Inc., we are the only custom contact pins manufacturer fully leveraging automatic die rolling technology — cold-forming precision pins with zero scrap and a defect rate of 1 in 600,000,000.
In 1943, Autoswage Products, Inc. was founded in Connecticut with a single purpose: manufacturing fluorescent lightbulb pins using a revolutionary cold-forming process called automatic die rolling. No cutting, no scrap, no waste.
Over three generations, that technology was refined and expanded to serve industries from automotive to medical devices. The core principle never changed — form the material, don't cut it.
In 2019, under the leadership of Keith Brenton, the company relocated to North Carolina and rebranded as Electropin Technologies LLC. New facilities, modernized equipment, same proven technology — now serving manufacturers Worldwide as Electropin Technologies LLC.
Eight decades of continuous innovation in precision pin manufacturing.
Founded in Connecticut as Autoswage Products, Inc. The company begins manufacturing fluorescent lightbulb pins using proprietary automatic die rolling technology — a cold-forming process that shapes wire stock without cutting or wasting material.
Under Keith Brenton's leadership, the company relocates to North Carolina and rebrands as Electropin Technologies LLC. Modernized facilities and expanded production capacity bring three generations of die rolling expertise into the 21st century.
Electropin Technologies LLC stands as the only custom contact pins manufacturer fully leveraging automatic die rolling. Refined processes achieve a defect rate of 1 in 600 million, producing up to 5 pins per second with zero material waste across 12 pin types.
With 35+ years of manufacturing experience, Keith Brenton leads Electropin Technologies LLC with a hands-on approach to engineering and operations. He works directly with customers to ensure every pin meets exact specifications.
Since taking the helm, Keith has driven the relocation to North Carolina, modernized production facilities, and refined the proprietary automatic die rolling technology that sets Electropin Technologies LLC apart. His vision: make Electropin Technologies LLC the go-to partner for manufacturers who demand precision, speed, and zero-waste production.
Work With Our TeamOur cold-forming process delivers advantages that traditional screw machining simply cannot match.
Wire stock is shaped through progressive dies without removing any material. Traditional machining wastes 60–70% of raw material. We waste nothing.
Automated cold-forming runs at production speeds that dramatically reduce lead times. From custom die creation to full runs, we deliver faster.
Consistency that traditional methods cannot match. Every pin is formed to exact specifications with remarkable repeatability from part 1 to part 1,000,000.
Because we form rather than cut, our dies maintain their precision run after run. No degradation, no mid-run quality drift.
Lead is added to brass so when machining it makes easier chips to clean up. Since we don’t create scrap, we don’t need lead. Our cold-forming process preserves material integrity and is REACH/RoHS compliant as standard.
All dies designed and manufactured in-house. Complete control over quality, rapid iteration, and the ability to take designs from concept to production fast.
