Two High Rolling Machine

GRM Two High Rolling Machine is a compact and versatile metal forming machine designed for reducing thickness, adjusting cross-sectional dimensions, and shaping various metal wires, strips, and profiles.
The machine consists of two horizontally arranged work rolls. During operation, the material passes through the roll gap and undergoes controlled plastic deformation under rolling pressure, achieving the required thickness reduction, width adjustment, or profile forming.
The Two High Rolling Mill can be used as a standalone rolling unit for material development and small-batch production, or integrated into GRM continuous rolling lines according to specific production requirements.

PV Busbar Ribbon Production Line

GRM PV Busbar Ribbon Production Line are designed to continuously process TU1 oxygen-free copper round wire into high-precision tin-coated flat conductive ribbon. The line is suitable for PV interconnection ribbon, busbar ribbon, and reflective busbar ribbon production.
The complete line integrates wire drawing, precision rolling, continuous annealing, flux treatment, hot-dip tin coating, and automatic take-up. It helps PV ribbon manufacturers control width and thickness accuracy, tin coating quality, strip straightness, and winding consistency.
The GRM busbar ribbon production line is approximately 26 m long and 3 m wide, with a total line weight of about 14 tons. The design speed can reach up to 150 m/min, depending on copper wire size, finished ribbon dimensions, tinning speed, and take-up method. Under typical production conditions, the monthly output can reach approximately 60-80 tons.
