Electroplating is a surface treatment process that reduces and deposits metal onto a workpiece (cathode) from an aqueous solution of metal salts using external current, providing corrosion resistance and a metallic finish. At Kounan Industry, we apply chrome plating to double nickel (semi-gloss nickel and glossy nickel) with high corrosion resistance for product manufacturing. We mainly perform plating on automotive seat belt components. For more details, please contact us or refer to our catalog.

Electrostatic spray painting, which utilizes the characteristics of static electricity to efficiently adhere paint to the workpiece, is mainly used for automotive exterior parts and office equipment components. Additionally, performing electrostatic painting after electrodeposition significantly improves corrosion resistance and weather resistance. By using an electrostatic spray gun and moving the workpiece at a constant speed via a conveyor, we achieve reliable and speedy painting. Furthermore, Kounan Industries actively promotes automation by utilizing reciprocating painting machines. For more details, please contact us or refer to our catalog.

Cationic electrodeposition coating is an electrodeposition method that uses direct current to charge the workpiece at one pole and the paint at the positive pole. The paint has weakly acidic properties and is applied using the cationic method, with a typical coating thickness of around 15 micrometers. It excels in heat resistance and corrosion resistance, and is used as a primer for parts that will undergo electrostatic painting in subsequent processes, in addition to automotive components. The process overview includes three lines: a conveyor-type line for small items and an elevator-type line for large items. Both are full dipping electrodeposition lines. Notably, the elevator-type line features a transfer system for moving jigs and operates with a 90-second cycle time, boasting excellent productivity.

In conventional electrocoating, when bending occurs, the coating can crack, revealing the substrate significantly. By using a paint designed for bending, while it may appear to have fine cracks, the visible cracks that expose the substrate have been eliminated. Improvements in the paint have enhanced its formability (bending), making it effective for processes that involve clinching, such as clamping in subsequent steps.
