Core Applications

This series is the ideal choice for producing the following key types of round wire:

Round interconnect ribbons for photovoltaic modules (PV round wire)

Wire stock for high-end fasteners, bearings, and precision shafts

Various metal wires requiring exceptionally high standards of roundness and surface quality

Technical Advantages

● High-Precision Roundness Control: Employs an optimized pass design and a high-rigidity, short-stress-line structure to ensure that the wire rod maintains exceptional roundness and diameter consistency, even during full-speed rolling operations.

● Superior Surface Quality: Features a precision-engineered roll system and an optional inline process lubrication system, significantly enhancing the wire rod's surface finish while minimizing scratches and surface defects.

● Stable and Efficient Production: Equipped with a highly responsive closed-loop control system and inline monitoring instrumentation, enabling real-time detection and automatic fine-tuning to guarantee dimensional stability and high efficiency in mass production.

● Flexible Configuration: Supports flexible mill stand configurations and rapid roll-changing solutions, accommodating a diverse range of processing paths—from pure diameter reduction to combined "reduction-and-shaping" operations—thereby meeting the flexible production demands for multiple product specifications and material types.

With exceptional roundness precision, outstanding surface quality, and reliable motion stability as its core values, the GRM-R series delivers top-tier round wire rolling solutions to customers—spanning sectors from new energy photovoltaics to high-end precision manufacturing—thereby empowering them to enhance their products' core performance and market competitiveness.
