After formal examination, material review, on-site verification, credit review, online publicity and other procedures, ZSME ZSME-HCL-1420 ultra thick surface treatment machine has been recognized as the first (set) major equipment and key components in Nantong City in 2025.

With the trend of thinning, miniaturization, and high-density development of electronic products, high-power electronic devices have higher demands for high current and high reliability. The market tends to use thick copper foil to meet the needs of high-power power transmission.

An important step in the production process of copper foil is surface treatment. Currently, the thickness range of copper foil treated by surface treatment machines in the industry is limited to 9-105μm。

ZSME has successfully developed the ZSME-HCL-14-420 ultra thick surface treatment machine with independent intellectual property rights and core technology, which meets the surface treatment requirements of 105-420 μ m ultra thick copper foil, achieving no scratches, no pressure pits, no color spots, no deviation, and no edge tearing. It fills the gap in the field of ultra thick surface treatment machine manufacturing in the equipment manufacturing industry, provides high-quality raw materials for downstream industries such as electronics and new energy, and promotes the technological upgrading and product iteration of related industries.

ZSME-HCL-14-420 Ultra thick surface treatment machine optimizes and upgrades the materials of mechanical components and power transmission devices, comprehensively enhancing the transmission kinetic energy. The entire section adopts tension PID closed-loop control, effectively avoiding situations such as adjustment oscillation and overshoot.
