Cylinder rod is a very important part for hydraulic cylinder,Wuxi YUTONG as a professional manufacturer of cylinder piston rod, we will have many steps to guarantee the quality of the rod, like
Inspection，grinding & peeling,cleaning & masking, and then hard chrome plating.
Hard chrome plating, and then OD grinding is an excellent answer for repairing and/or providing wear resistance to parts such as cylinder shafts, rolls, hydraulic cylinders, rams, pistons and rods. It is used in everything from plating jewellery with gold to applying reflective metal plating to satellites and spacecraft. In this process, objects to be plated are placed in a bath containing a solution of dissolved metal molecules (in our case this metal is a special Chromium formulation). Electrodes are attached to the object to be plated and a positive current is applied to the solution. As the current runs through the solution and out through the electrodes, it causes the dissolved metal particles in the solution to be attracted to and adhere to the metal surface of the metal.
In the case of hard chrome plating, these principles are the same. The chromed rods are placed in this electrolytic soup for a specific length of time in order to build up the required layer of fresh new chrome. This stage is more technical though due to the demands of the hardness, and the quality of the surface finish required. Precisely the right amount of current must be delivered at a steady rate whilst bath chemistry and temperature are maintained for the duration of the plating process. Any mistakes or interruptions in power or temperature at this stage will result in a bad chroming job, which will cause the cylinder to fail very soon after repair.
