Our hydraulic manifold is processed by advance horizontal CNCs, equipped with a high-end profile cutter to ensure the verticality and flatness of the valve port. In addition, we conduct different surface treatments according to the material, for instance, the aluminum alloy material hydraulic manifold is mainly treated by hard anodizing and nickel plating or galvanized nickel plating for carbon steel. All of our hydraulic manifolds can be qualified the salt spray resistance test for more than one thousand hours, reaching C4H standard and meeting various low temperature and complex operational conditions.
