Hot pressing and calendering of high-quality nonwovens places strict demands on roller surface precision and temperature control uniformity. The mirror rollers, created using multi-step precision machining processes, meet medical and filter media manufacturing standards. Rollers are made from alloy steel or 304 stainless steel, heat treated for hardness, and plated with hard chrome for wear resistance and oxidation resistance. The roller body undergoes multi-stage ultra-precision polishing combined with internal temperature circulation channel to ensure stable roller surface temperature and uniform thickness and luster of fabric after hot pressing.
Strict control of roller roundness and alignment ensures balanced force during high-speed pressing, preventing uneven fabric thickness. Laser engraving equipment allows you to create custom roller surface textures, balancing calendering and texture shaping. The company has complete production lines for heat treatment, electroplating and dynamic balancing. The products are compatible with mask fabrics, filter membranes and nonwovens for automotive interiors. Draw process optimization and sample making services are provided to provide reliable support for main rollers for high quality nonwovens production lines.
