1. Copper Machined Parts

Machined Copper parts are produced using CNC turning, drilling, tapping, and multi-axis machining, typically from Copper rods or billets (C11000, C10100, Cu-ETP).

These parts are widely used where tight tolerances, conductivity, and repeatability are critical.

Typical Copper machined components include:
Copper terminals, Copper lugs, Copper bushings, Copper machined washers,  Copper Studs for transformers,  Copper bushes,  Copper spacers, Copper sleeves, Copper connectors, Copper studs, Copper inserts, Copper sensor housings, Copper valve components, Copper current-carrying parts, and Copper grounding accessories.

Industries using machined Copper parts include electrical switchgear, power distribution, renewable energy, EV systems, railways, transformers, and industrial equipment.

2. Copper Pressed / Stamped Parts

Pressed or stamped Copper parts are manufactured from Copper sheets or strips using power presses, progressive dies, and precision tooling. These parts are ideal for high-volume production.

Common Copper pressed components include:
Copper terminals, Copper contacts, Copper washers, Copper shims, Copper clips, Copper contact plates, Copper earthing strips, Copper connectors, Copper brackets, Copper fuse links, Copper busbar laminations, and Copper grounding plates.

These components are extensively used in automotive wiring harnesses, electrical panels, circuit breakers, relays, switchgear, electronics, and battery systems.

3. Copper Milled Parts

Milled Copper parts are produced using CNC milling, VMC machining, and multi-face machining, often from Copper plates, flats, or blocks.

Typical Copper milled components include:
Copper busbars, Copper distribution bars, Copper current collectors, Copper heat sinks, Copper plates, Copper mounting blocks, Copper grounding bars, Copper laminated connectors, Copper power plates, and Copper high-current conductors.

These parts are essential in transformers, UPS systems, EV chargers, substations, data centers, power electronics, and renewable energy installations, where low resistance and heat dissipation are crucial.

4. Copper Forged Parts

Copper forged parts are manufactured through hot forging or cold forging, resulting in superior grain flow, high mechanical strength, and low electrical resistance.

Typical Copper forged components include:
Copper forged lugs, Copper forged terminals, Copper forged connectors, Copper forged clamps, Copper forged grounding connectors, Copper forged cable terminals, Copper forged electrical joints, and Copper forged current connectors.

Forged Copper parts are preferred in high-current, high-stress applications such as power transmission, substations, heavy electrical equipment, railways, and industrial grounding systems.
