Copper pin

for electrical contactsISO

The electrical contact pin is made from high-conductivity copper alloy with a nickel-plated surface for durability and stable performance. With a precision tolerance of ±0.01 mm, it ensures reliable connections in connectors, electronic assemblies, and circuit testing applications. At HLC, electrical contact pins are engineered with precise ±0.01 mm tolerances using high-conductivity copper alloy. Terminals are formed through high-speed stamping and finished with nickel plating to enhance conductivity and corrosion resistance. The plated terminals are then integrated with plastic housings through in-mold riveting or insert molding on our automated assembly lines. Backed by IATF 16949 and ISO 13485 certifications, every pin is inspected to ensure consistent quality and reliable performance for automotive and electronic applications. At HLC, we combine over 20 years of precision manufacturing experience with advanced stamping, molding, and automated assembly technologies. Our IATF 16949 and ISO 13485 certifications demonstrate our commitment to the highest quality standards. With in-house tooling, automated inspection systems, and strict tolerance control down to ±0.01 mm, we ensure every product delivers consistent reliability. From small-scale prototypes to high-volume production, we provide custom solutions tailored to your needs, helping you reduce costs, improve efficiency, and accelerate time-to-market. - Material: Copper alloy + Plastic - Surface: Nickel plated - Tolerance: ±0.01 mm - Application: Connectors, electronic assemblies, circuit testing
