Auto Barrel is innovative and versatile plating. Barrel even though it is created to be used on modern automatic plants, for zinc/nickel plating. It can be easily adapted for auto/semi-auto/manual plating lines. Barrel offer state-of-the-art performance for every zinc and nickel plating plant. The barrel body is fully bent with PP material, complete forming without welding, and firm and heavy weight capacity. Further. The components are strengthened by PP to increase temperature and yield resistance. The exterior is covered with PP material of acid and alkaline resistance. The punching diameter on the barrel is designed based on the dimension of the workpiece. The round-type hole on the barrel body is punched to increase the water penetration and electric conduction efficiency.
