15 Cage Shaft
The cage shaft of the rotary screen paper machine is a long shaft that runs through the entire cage. After the bearing seats at both ends are worn out of tolerance, they cannot be repaired by shaft replacement or surfacing, but can only be scrapped. A net cage is about 8,000 yuan. The use of brush plating technology can accurately repair the out-of-tolerance size of the bearing position and restore the performance of the cage. The cost of brush plating is only about 200 yuan.
casting
Casting and forging equipment work in dusty and corrosive environments, and the wear and corrosion of mechanical parts will be more serious. wococarbie.com can repair various parts of the hydraulic system of the casting machine, such as the repair and renovation of the hydraulic plunger, etc., and cooperate with various parts, such as the bearing position, the sealing position, the chemical industry, and the pesticide machinery because they are often acidic and corrosive. Therefore, when repairing this type of machinery, the problem of anti-corrosion should be considered. The hydraulic plunger of Xinyi Pesticide Factory is repaired by electric brush plating. 1.

glass industry
A layer of ceramics is sprayed on the surface of the lifting roller and the conveying roller by thermal spraying to improve the corrosion resistance of the lifting roller and the conveying roller to the molten glass, inhibit the adhesion of the molten liquid phase on the surface of the roller, and slow down the erosion of the molten glass on the surface of the roller. The roller surface remains smooth for a long time, reducing the maintenance of lifting rollers and conveying rollers, improving glass quality and production yield, and reducing production costs.
Electrician's wire
The carbide ceramic coating is sprayed on the surface of the drawing tower wheel, wire drawing machine, wire drawing wheel, wire wheel, wire drawing cylinder, wire take-up disc, guide groove and other parts by the supersonic flame spraying process, so that the surface hardness can reach HRc75, which is far better than that of abrasive tools. The wear resistance of steel or chilled cast iron is high; the base body of these parts can also be made of ordinary steel or cast iron, which not only reduces the cost, but also prolongs the service life.
