RMM offers a complete range of corrugated roll products, backed by 30 years of experience and strong data support from partnerships with machinery manufacturers, enabling us to provide exceptional technical services that meet industry standards.
Pressure RollsReduce Corrugated Board Deformation
RMM‘s pressure rolls are made from high-strength 45# steel, offering excellent wear resistance and thermal stability. The roll shafts are coated with chrome plating, which enhances their corrosion resistance and durability, ensuring that the pressure rolls can operate reliably in high-intensity work environments over long periods.
Achieves even bonding of all layers of corrugated board for high adhesive quality.
Low thermal expansion, reducing deformation and ensuring even heat distribution during high-temperature operations.
Suitable for high-speed production lines, maintaining stability and consistency.
Accurate crown height to avoid common issues like indentation lines and poor bonding.
Customization available, with pressure rolls designed to meet specific customer needs.
Periphery Heating Pressure RollsUniform Heating for Perfect Bonding
RMM’s periphery heating pressure rolls, made from durable 50# steel with a wear and corrosion-resistant chrome coating. The pressure roll’s precision temperature control system guarantees uniform heat distribution, optimizing bonding and shaping in corrugated production.
Ensures uniform heat distribution, reducing temperature fluctuations and preventing localized heating.
Maintains optimal, stable temperatures to promote glue curing and ensure stronger adhesion between layers.
Minimizes energy waste through a focused heating design.
Stable temperatures ensure smoother production, improving speed and reliability.
Diameter up to 601 mm and width up to 3600 mm, suitable for various production line requirements.
Glue Rolls and Doctor RollsStable and Effective Glue Application Solutions
