Chromium plating of rollers for different fields of industry, in particular for through-feed presses used for the ironing and polishing of leathers.
Rollers’ hard chrome coating has a variable thickness from 0,1 mm to 0,2 mm and 70 HRC hardness approximately, while the final roughness Ra = 0,001 micron approx.
Superfinished surfaces, mirror polished, are obtained on the chrome layer through special and sophisticated processes permitting to reach an approximate surface roughness Ra = 0,001 micron.
These types of surface’s finishing give the possibility to get the maximum shine on leathers, highlighting their quality.
The processes of matt, sandblasting and microengraving made on the surfaces, at different roughness and obtained through exclusive processes, have the purpose to hide the existing defects on leather’s surface, reaching the best evenness increasing the leather quality as much as possible.
All these solutions are offering evident and considerable advantages if compared with the traditional haircell embossing, avoiding repeating marks and permitting to remake the sandblasted or microcell process on damaged rollers or the transforming from a type to another one independently from the roller’s body diameter.
