Production process and product advantages of C62300 copper strip and copper coil:

1. Production process

Continuous extrusion method

The production of C62300 copper strip adopts continuous extrusion process, which heats and deforms the Φ20 copper rod through continuous extrusion equipment, and combines circulating water cooling to form a blank with the required cross-sectional shape. This technology has the characteristics of high efficiency and energy saving, high yield rate and short production cycle. The product has high conductivity, low oxygen content and excellent mechanical properties.

Rolling process

The process includes: incoming material inspection → milling surface and edge milling → rough rolling → intermediate annealing → finishing rolling → finished product annealing → surface cleaning → shearing → packaging.

Key steps such as annealing (700-750℃) and rolling treatment ensure that the material structure is dense and the performance is stable.

Some processes combine copper powder sintering with multiple rolling to improve material uniformity and mechanical strength.

Application of advanced technology

Adopting large ingot hot rolling, constant pressure cold rolling, thickness automatic control and other technologies, combined with advanced annealing equipment, to ensure high precision and surface finish of the product.

Copper coil stacking technology (such as MULTICOIL®) supports simultaneous processing of multiple coils, reducing stamping downtime and mold loss.
