·Features: WC mirror roll material selection: high quality domestic steel and imported steel, 20 steel, forging alloy steel (42GrMo, 38grmoal), quenching and tempering with advanced heat treatment process, stress relief and quenching. The wall thickness of the inner hole is uniform after machining and the surface is smooth after quenching;

·The application shows that the service life of WC roller is longer than that of metal roller and ceramic roller, the mesh gap rate is almost zero, the corrosion resistance is stronger, and it is clearer and simpler;

·Adapt to printing services: all kinds of flexo printing, high precision printing, coating printing and other printing services; ·Material selection: high quality domestic steel and imported steel, No. 20 steel, forging alloy steel (42GrMo, 38grmoal), quenching and tempering with advanced heat treatment process, stress relief and quenching. The wall thickness of the inner hole is uniform after processing, and the surface hardness can reach hrc50-58 after quenching

·Internal structure: heating or cooling structure, two or three layers, spiral or Z-shaped channel. Inner sleeve and roller body interference red. Water in and out on both sides or on the same side.

·Surface treatment: spray tungsten carbide.

·Machining accuracy: temperature difference ≤± 1 ℃, thermal deformation ≤ 0.01mm, flatness, runout, coaxiality ≤ 0.001mm.

·Product application: calendering and high precision coating on the surface of plastic sheet, leather, paper, metal, film and nonwovens.
