Corrugating Rollers Advantange:
1. The coating is firmly combined with the substrate to ensure long-term use of the coating without falling off;
2, the coating hardness is high, wear resistance increases exponentially, life is linear extension;
3. The coating thickness is uniform and controllable, that is, the precision of the corrugated wheel can be guaranteed;
4. The surface roughness before coating treatment can reach ra0.3-0.5um. After grinding with special diamond grinding wheel cutter, the surface roughness reaches and is higher than the surface roughness of electroplated hard chromium roller.
5. Cooperate with UV type and UVV type corrugated design, can effectively improve the hardness of cardboard, reduce the amount of paste and waste of core paper;
6, in the use of the corrugated type, the theory of wear and tear, long-term guarantee the paper rate unchanged;
7, corrugating roller since the use of the machine, the production of cardboard maintained in the thickness, printing always flat, stable control of cardboard and carton quality;
8. The coating is removed by special method, and the wheel blank can be reused;
9. The improvement of service life reduces the frequency of change, which also saves labor and material costs;
