Cylinder in Hydraulic Support

Product Overview

Composite additive manufacturing technology is applicable for producing new hydraulic support columns and repairing existing ones. The process involves laser additive manufacturing of copper alloy/stainless steel on the inner surface and high-hardness stainless steel on the outer surface, effectively repairing corrosion and wear defects while restoring column dimensions. This method significantly enhances surface wear and corrosion resistance, resulting in a service life three times longer than traditional electroplated columns.
