Rectifiers for any type of metal plating, whether nickel, tin plating or another, are placed and programmed to give better control of a plating project and allows the option of altering the currents when wanted. Currents can be sent in various combinations, reversed, pulsed or just be a basic forwards movement. The more control an electroplating service has over their project, the better the results. Plating rectifiers allow that kind of control.

Rectifiers today

The kind of concept that rectifiers come from now is much the same as a few decades ago, but of course, there have been improvements in materials used and methods in manufacturing. Those advances are of most obvious in computerization and electronics. There are five things all rectifiers have in common;

  1. A transformer that is there to lower the high voltage from the utilities to what electroplaters use which is 6 to 18 volts usually.
  2. Power regulators.
  3. To be able to change currents from AC, alternating current, to DC, direct current with a rectification system.
  4. A way to cool the components down.

Basic rectifiers versus more complex

Single-stage rectifiers are more affordable than ones that can handle different currents, patterns and styles. But the extra cost of the more complex versions can be worth paying for, it is something any electroplating service has to decide on. That choice will depend on things like how many materials they are producing, how much money there is to invest in that project and the kind of control that is needed for that particular project.

If you are a home plater working from home then investing in extra equipment is a lot harder, the space needed, the money and so on. For you, something basic and simple is affordable at less than a hundred dollars and can still help with your project.

Keep it cool

It is important when using rectifiers that they are kept cool. It should be kept close to the solution tank so that there is not too much of a loss in current, but still away enough that cooling from a fan does not affect the corrosives in the bath. Most often air cooling is an easier solution but in some cases when tin plating or doing any electroplating, water-cooled units can be used. These are made to be airtight so vapours from the component will not be able to get inside the unit.

Rectifiers need to be kept at the right temperature because otherwise if they overheat that directly impacts how well they can deliver the power in a consistent and smooth manner. The only moving part on rectifiers is the cooling fan if being air-cooled. If they are looked after properly and filters are cleaned or changed regularly, they can have a very good life span.

Summary

For the best in experience, knowledge and skill when it comes to using rectifiers and electroplating, find an electroplating service near you with good reviews and a good reputation in the industry.
