Development of Pollution-Free Rapid Plating System
It is in the plating process that the worst bottleneck occurs in plant automation. We, however, have succeeded in making our plating process free from pollution and compact, allowing us to install this system within a production line and consequently establish a continuous production line resulting in a decrease in plating cost to about 1/2 of the previous cost. We have achieved an excellent chrome plating speed of 60µ/min, by placing an anode relatively close to the part to be plated and by sending the plating solution into the space between the two by means of a pump. This provides a plating speed 100 times faster than with conventional methods, while improving the quality of the plating coat considerably. The system is optimum for functional platings, and can be used for the plating of shock absorber rods, engine valves, engine cylinders, etc.
