Flat Wire Rolling Mills

The GRM flat wire rolling mill is a specialized rolling system developed specifically for the high-precision rolling of flat wires and strips. Featuring a modular design, it offers flexible configuration options—supporting either Two-High Rolling Mill units or Four-High Rolling Mill units—to precisely match varying feedstock dimensions and finished product specifications. This system is dedicated to meeting the rigorous demands for high-end flat metal materials across industries such as electronics and appliances, precision springs, and photovoltaic new energy.

Core Applications

This series serves as the ideal solution for the production of the following key components:

Precision connectors, contact reeds, and lead frames

Various types of precision flat springs

Specialized flat conductors, such as photovoltaic busbars

Other flat wire materials requiring exceptionally strict dimensional tolerances and material property consistency

Technical Advantages

● High-Rigidity Constant-Speed Design: The GRM flat wire rolling mills feature a short-stress-line roll system and a high-rigidity stand design, ensuring exceptional dimensional stability and low-vibration operation even during high-speed rolling.

● Micron-Level Precision Control: Standard configurations include a high-response servo control system and a high-precision roll gap adjustment mechanism, enabling micron-level control over material thickness and width.

● Intelligent Flexible Production: The production line supports online dimensional measurement and automatic closed-loop adjustment; optional modules for process lubrication and temperature control are also available to ensure consistent material properties.

● Enhanced Process Support: The GRM flat wire rolling mills are equipped with rapid roll-changing and recipe management capabilities, facilitating flexible production for small-batch, multi-specification manufacturing runs.

Centered on high precision, high stability, and advanced automation, the GRM flat wire rolling mill provides customers with high-quality, high-efficiency flat strip rolling solutions, empowering them to elevate the manufacturing standards and market competitiveness of their core components.
