Tungsten Carbide Corrugating RollsMaximizing Production Potential

RMM’s tungsten carbide corrugating rolls outperform standard chrome-coated rolls and are manufactured using premium 50CrMo alloy steel and advanced tungsten carbide coating technology. They can be refurbished 3-4 times and offer excellent wear resistance, preventing tooth deformation. RMM’s tungsten carbide corrugating rolls service life is 3-5 times longer than chrome-plated corrugating rolls.

Superior performance in high-speed production lines
Better handling of low-grammage paper production
Consistent and Reliable Product Quality
Significantly Reduced Material Waste
Less Downtime and Maintenance Costs
Maximum Width of Up to 3.6m for Increased Capacity

Micro Flute Tungsten RollsPrecision Meets Performance

To break the prejudice that micro flute corrugating rolls can only be chrome-plated, RMM’s micro flute corrugating rolls with a tungsten carbide coating offer outstanding wear resistance. Featuring high-precision surface treatment with a roughness similar to chrome coating, these rolls significantly reduce the risk of paper damage and provide extended lifespan.

Minimized Paper Stretching and Warping
Reduced Raw Material Waste During Production
300 sets of E flute tungsten coating corrugating rolls yearly
Stable Production Quality for F, G, N, and O-Flute Boards
Enhanced Flatness and Improved Print Performance

Peripheral Heating Corrugating RollsRevolutionizing Efficiency and Quality in Cardboard Production

RMM’s exclusive peripheral heating technology patent features an innovative axial channel heating design, overcoming the limitations of traditional heating methods. This significantly enhances thermal conductivity, enabling rapid heating in just 5 minutes and reducing the banana effect caused by uneven heating. This innovation significantly reduces paper waste and various other wastes by minimizing downtime in the corrugated cardboard production process.

Accommodates Full Range of Base Papers from 50 to 250 g/m²
Effectively Solves low-grammage Paper Breakage Issues
Resolves Adhesion Issues on Wide-Format Production Sides
Reduces Energy Consumption and Exhaust Emissions
Significantly Enhances Cardboard Quality with Superior Corrugation Formation

Unique Production Methods, Exceptional Performance

Advanced Hardening Processes

RMM’s proprietary triple heat treatment method, which includes Nitriding, Quenching, and Cryogenic Treatment, offers enhanced stability for corrugating rolls. This results in higher-quality, flatter corrugated boards that are better suited for printing.

Low thermal expansion coefficient leading to minimal deformation
More uniform temperature distribution during operation
Enhanced hardness uniformity across the corrugating rolls
Effective removal of processing stress
Superior performance with both high-speed and low-grammage paper grades

Innovative Tri-Arc Structure

RMM’s innovative tri-arc structure delivers exceptional performance with faster operating speeds and extended service life. This advanced design effectively reduces resonance and operational noise while expertly handling both heavy and low-grammage papers, minimizing breaks and optimizing energy consumption.

Maximum speed of 450 m/min, 28% faster than standard rolls
Accommodates paper grammage from 50 to 220 g/m² for varied production needs
Lifespan up to 35-50 million meters, up to 130 million meters maximum, 40-100% longer than standard corrugated rollers
Reduces breakage in low-grammage paper production, improving efficiency and saving wood resources and energy
