GRM-R Series

The GRM-R series is a rolling system specifically designed for the precision reduction, sizing, and shaping of high-quality round wire. Catering to industries with stringent requirements regarding roundness, diameter tolerance, and surface finish, this series offers efficient and stable solutions. It is particularly widely utilized in the manufacturing of photovoltaic solder ribbons (round wire), high-end fasteners, precision shaft components, and specialized wire products.

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.
