Precision-Engineered Connector Pins:
Our Expertise, Your Competitive Edge
Connector pins — machined pins, contact pins, turned pins — are microscopic backbone of electronics. At MetalWorks Plus, we specialize in manufacturing these components to the most exacting standards. With over a decade of experience in CNC turning, precision grinding, and surface finishing, our team delivers metal pins with tolerances as tight as ±0.002mm. From prototype to mass production, we serve industries including consumer electronics, automotive connectors, medical devices, aerospace, and industrial automation — all from our ISO-certified facility in Shenzhen, China, with seamless global logistics.
Micron Tolerance
We achieve tolerances down to ±0.002mm on connector pins using advanced Swiss-type CNC lathes and CMM verification.

Mastering the Surface: A Spectrum of Finishing Expertise for Precision Pins
The right surface finish enhances conductivity, corrosion resistance, contact reliability, and aesthetics.
Gold Plating (Electrolytic)
Hard gold and flash gold plating for signal & RF connector pins. Thickness: 0.05–2.54μm.
Tin / Tin-Lead Plating
Cost-effective solderable finish for terminal pins and crimp contacts. RoHS-compliant.
Silver Plating
Exceptional conductivity for high-current contact pins. Thickness: 2–25μm with anti-tarnish.
Nickel Plating
Uniform sub-micron coating providing hardness (HV 500+) and corrosion protection.
Anodizing (Type II & III)
Hard-coat Type III anodizing for aluminum connector pins — up to 50μm thick oxide layer.
Passivation
ASTM A967 & AMS 2700 passivation for stainless steel pins, enhances corrosion resistance.
