Brass Cold Forging
Brass Cold Forging is a precision metal forming process that shapes Brass workpieces at room temperature by applying high pressure to deform the material into the desired configuration without removing any material. This sophisticated manufacturing technique capitalizes on the exceptional malleability and ductility of Brass alloys, allowing for complex geometries to be achieved with minimal waste. Unlike traditional machining processes that cut away material, cold forging rearranges the metal’s grain structure, resulting in improved mechanical properties, enhanced strength, and superior surface finish. Our advanced cold forging processes enable the production of components with exceptional dimensional accuracy (up to ±0.02mm), tight tolerances, and excellent concentricity. The process is particularly advantageous for high-volume production scenarios, offering significant cost advantages through reduced material usage, decreased energy consumption, and minimal secondary operations, while simultaneously enhancing the performance characteristics of the finished components.
Brass Cold Formed Parts
Brass Cold Formed Parts represent the pinnacle of precision engineering, offering unparalleled advantages in terms of structural integrity, surface quality, and cost-effectiveness. These components, produced through controlled deformation of Brass alloys under high pressure at ambient temperatures, feature a distinctive grain flow pattern that follows the contours of the part, dramatically enhancing fatigue resistance and mechanical strength compared to conventionally machined components. Our cold formed Brass parts exhibit exceptional dimensional stability with repeatable tolerances as tight as ±0.01mm, superior surface finish (typically Ra 0.4-1.6), and remarkable thread quality when applicable. Commonly manufactured items include threaded fittings, valve components, electrical terminals, fasteners, plumbing components, and specialized hardware for demanding applications. The elimination of material waste, combined with reduced secondary operations and finishing requirements, makes our cold formed Brass parts an economically and environmentally sound choice for applications requiring precision, reliability, and aesthetic appeal.
Cold Forming of Brass and Copper
Cold Forming of Brass and Copper encompasses a family of sophisticated manufacturing techniques that leverage the exceptional formability of these non-ferrous alloys to create complex components through controlled plastic deformation. This versatile metalworking approach includes processes such as extrusion, heading, coining, swaging, and thread rolling – all performed below the recrystallization temperature of the material. Our specialized cold forming technologies are optimized for the unique metallurgical properties of various Brass alloys (C36000, C37700, C38500) and Copper grades (C10100, C11000), ensuring maximum material performance and process efficiency. The cold forming process fundamentally alters the metallurgical structure of these materials, increasing hardness and tensile strength by up to 30% through work hardening while maintaining excellent electrical and thermal conductivity. This combination of properties makes cold formed Brass and Copper components ideal for applications requiring mechanical strength coupled with excellent conductive properties, such as electrical connectors, terminal blocks, and heat transfer components.

Manufacturing Processes
Our comprehensive cold forming capabilities include multiple specialized processes, each optimized for specific component geometries and production volumes:
Forward Extrusion: Material is forced through a die opening, reducing cross-sectional area and creating elongated profiles.
Backward Extrusion: Punch forces material to flow in the opposite direction, creating hollow components with controlled wall thickness.
Heading: Material is upset to form larger cross-sectional areas, typically used for bolt and fastener heads.
Coining: High-pressure compression between two dies creates precise surface details and dimensional control.
Thread Rolling: Threads are formed by displacing material between hardened dies, creating stronger threads than cutting methods.
Swaging: Reducing the diameter of tubes or rods by radial compression forces.
Combined Operations: Multiple cold forming operations performed in sequence on progressive tools.
