Plasma technology is used to spray ceramic coatings onto the piston rods of gate operators.


Plasma technology is used to spray ceramic coatings onto the piston rods of gate operators.

Guangzhou Sanxin uses plasma technology to apply ceramic coatings to hydraulic cylinder piston rods. This ceramic coating technology boasts features such as excellent corrosion resistance, superior wear resistance, high precision in opening and closing strokes, ease of maintenance, and an environmentally friendly manufacturing process. As a result, it will effectively extend the service life and improve the operational efficiency of the equipment, ensuring safe and reliable operation of the project.

Ceramic piston rod hydraulic hoist. During the manufacturing and assembly of the hoist, instruments such as a metal hardness tester, coating thickness gauge, surface roughness meter, and steel tape measure were used to inspect the quality indicators of the piston rod section. The inspection report is shown in the figure below.
