Copper Plating

After proper inspection of Steel base shell, for proper size and surface, the cylinder after degreasing process, is immersed in formulated Alkaline Pre-Copper tank, to ensure proper bounding of Hard Copper Plating. High purity copper 99.9% oxygen free is used in balanced electrolyte chemistry ensures that the plated cylinder achieves optimum hardness (200 to 220Hv) and grain structure for Engraving cells
