A supply of metal parts are electroplated by progressively transferring the parts with a computer controlled robot into a series of open top tanks containing solutions. The tanks have submerged metal fixtures which temporarily support the parts, and each fixture in the electroplating tank is individually connected to a direct current power source through a corresponding timer switch controlled by the computer so that each part is plated for a precise time period independently of the time the part remains in the plating solution. Each fixture is coated with an insulation material and has a base with metal contact with a removable fixture member having limited metal line contact with the supporting part. A plurality of electroplating lines each include the above components, and common tanks in the lines receive an electroplating solution recirculated through a common filter and service tank where the solution is heated and controlled.
