High Precision Copper Alloy Strip Cold Rolling Mill

The High-Precision Copper Alloy Strip Cold Rolling Mill, developed by GRM Rolling Mill, stands as a core piece of equipment specifically engineered for the precision processing sector of the non-ferrous metals industry. By integrating GRM’s proprietary roll system architecture with an intelligent closed-loop control system, this equipment not only achieves micron-level thickness tolerances but also attains a leading position in China regarding strip shape control and flatness. It represents the ideal choice for producing high-quality copper strips in the fields of electronics and semiconductors, new energy lithium-ion batteries, and aerospace.

Core Advantages:

● The High Precision Copper Alloy Strip Cold Rolling Mill employs six-high reversible cold rolling technology, featuring an optimized work roll diameter design. This ensures a minimum rolling thickness of 0.05 mm while maintaining exceptional rolling stability, thereby resolving the critical challenge of rolling instability associated with ultra-thin strips.

● Equipped with a hydraulic AGC (Automatic Gauge Control) system—integrating high-precision thickness gauges and closed-loop control algorithms—the mill achieves precise thickness control within a tolerance of ±1.5 μm; the Ultra-Precision model attains an exceptional accuracy of ±0.001 mm.

● Utilizing a fully digital drive system and PLC programmable controllers, the mill implements advanced functions such as automatic tension control, automatic coil diameter measurement, automatic strip length recording, and automatic head-end rolling. This significantly reduces the reliance on highly experienced operators.

Application Fields:

GRM Rolling Mill’s High Precision Copper Alloy Strip Cold Rolling Mill is widely applied in:

● Electronics Industry: Lead frames, connectors, and interconnects

● New Energy Sector: Lithium-ion battery copper foil, solar cell substrates

● Automotive Manufacturing: Automotive electronics, heat sink materials

● Aerospace: Specialized copper alloy structural components

● Home Appliance Industry: Refrigeration equipment, motor windings
