Sinoboom has explained the row of small holes found on its scissor forks.
Rather than being a unique visual mark of the manufacturer’s product, the holes facilitate the flow of electrophoresis fluid inside the fork.
Electrophoresis is one of the most effective methods for coating metal components. The process of electrophoretic coating involves immersing a conductive substrate in an electrophoretic coating tank filled with a low-concentration dilute mixture, as the anode (or cathode), and the corresponding cathode (or anode) is set in the tank. After the direct current is connected between the two poles for a period of time, a uniform fine and insoluble coating film is deposited on the surface of the object being coated.
Compared with other primers, electrophoretic primer has a number of advantages, says the company. The electrophoretic coating has a high penetration rate and can penetrate into the interior and gaps of the coating; the paint film is uniform, fine and compact, has strong corrosion resistance and is impact and wear resistance, along with corrosion, discoloration and aging resistant. Electrophoretic also has low solvent content, which is conducive to environmental protection and production safety.
