This is what is need on electroplating business. Electroplating need DC power source that can supply DC electric current with stable current flow. This one is a special problem for home industry, beside the supply of Electric source can't stable, and the price of build up DC electric converter with high current flow too expensive. For industrial company this may can supply by high power system that already make with perfect electric circuit, so DC electric current is not a problem anymore. In our country this always problem because electric source that supply from government still don’t stable the range is too far for example from 170 volt to 210 volt, this can make difficult to arrange even use current controller.
The above problem make the quality of deposit coated metal such as in chromium plating can't stable, sometimes thick but sometimes too tin. The brightness and the regularity of thickness can be not even if the electric source is not stable flow. For small part may can result in evenly coated thickness but for wide part this can be problem if electric current flow is not high enough or less from the limitation. The DC current electric source should be able to supply electric current 5 A per sq ft of object to coat by chrome ion. If the electric current up and down to wide span, this can be difficult to arrange.
Chrome plating result itself is not just the preparation of base metal such as electropolishing but also from the DC current electric flow also should be stable. If any certain disturbance while running process the chromium deposit can be very brittle or too soft, out of the standard quality.
