Sanding machine rubber roller 

Printing machine rollers (rollers) are made of various materials (cast iron rollers, cast steel rollers, aluminum rollers, chrome-plated rollers, etc.). If the appropriate repair process cannot be selected in a targeted manner, poor repairs will often occur: 1. There is thick and hard printing ink remaining on the surface of the used roller (roller), and there is more dirt in the corroded depressions. If only brush plating is used, the bonding force between the coating and the substrate will be low. However, if a cold welder is first used for priming and then brush plating, such a problem will not occur. 2. The plating thickness capability of traditional plating solutions is poor, and the safe thickness is generally less than 0.2 mm (unilateral). For workpieces whose restored size is greater than the safe thickness, the quality of brush plating cannot be guaranteed, and the stacking thickness of our company's cold welding machine is unlimited. 3. The coating deposition speed is slow,…
