Continuous Chrome Plating line:
Here follow the main differences between Traditional Plating and the new technology of Continuous Plating Line.
The conventional horizontal Rack Plating or the vertical Dip Plating, which are the most common plating technologies adopted in the Hard Chrome Plating field around the world, can be described as a step-by-step batch treatment requiring considerable human intervention. In the conventional plating methods, the chromium plating operation takes place on stationary bars; the dipping rack carrying the bars deep into the bath, horizontally or vertically, for a period of time.
The bars are mechanically and electrically fixed to the rack which is connected to the cathode. The anodes are placed on the long side of the tank, there is no way to create an electric field concentric to the bars and this leads to thickness variations in the chromium overlay. In Conventional Plating, especially when the chromium-plated bars are pulled out from the tanks, a big deal of harmful fumes escapes into the working rooms. Labor as well as the risks from human exposition to hazardous substances are the most relevant problems related to this technology, not mentioning the problems related to Current Distribution and consequently uneven thickness on the work piece.
The Continuous Plating process is an innovative but well tested method for the production of high quality chrome plated bars and tubes for pistons rod and linear shaft. In the continuous chrome plating process, the grinded bars to be plated run longitudinally through a plating device one after the other continuously.
The Continuous Chrome Plating is an evolution of the traditional galvanic Chromium Plating in terms of management, productivity and efficiency. The grinded bars, depending on size, are moving at different speeds according to the chrome layer we desire to achieve.
The continuous chrome plating process is able to put a multiple-chrome-layer, depending on the number of chrome tanks in line, with the result of increasing the corrosion resistance.
The Continuous chromium plating process is done with many circular anodes, and the bar advances through the anodes, so that a completely homogeneous chrome layer is guaranteed.
