Why do I need a rectifier for electroforming

A rectifier is probably the first thing you should get if you intend to electroform or electroplate an object. Without a rectifier, you won&#;t be able to provide the electricity needed to plate your creation.

Basically, rectifiers convert AC (alternative current) to DC (direct current). For electroforming, you need a steady direct current to obtain a good plating.

Rectifiers come in all shapes and sizes. If you&#;re a beginner you can get a simple, easy to use power supply. You don&#;t need it to be very powerful since you are using it on very low voltage for electroforming. 

How do you use a rectifier for electroforming

You&#;ll definitely get better results if you know how to properly use your rectifier for electroforming. First, you need to attach your negative clip to the object you wish to electroform and positive to the anode. Then, you need to figure out the right voltage for your project. This is an important part of the electroforming process. To know the exact voltage you need to plate your piece, you have to calculate the square inch of the surface area you want to electroform. It can be done using this tool. You&#;ll be setting your amps at 0.1 amps per square inch of surface area. In other words, if you want to plate 5 inches of surface area, you&#;ll be setting your rectifier to 0.5 amps.

Once your rectifier is turned on and set on the voltage of your choice, you&#;ll notice a slow build-up of metal on your piece. If you use high current, your piece will become grainy. This can be interesting if you wish to have texture on your creations. However, for a smooth result, a low voltage is always best. You&#;ll have to check your piece periodically and make adjustments (turn the power up or down) until you obtain the desired texture. I leave my pendants at least 8 hours in the bath &#; but more often 15-24 hours. 

How to choose the best electroforming rectifier

 

If you&#;ve never bought a rectifier before, you probably don&#;t know what you should be looking for. You don&#;t wanna buy just any power supply and end up with something that&#;s not going to work for electroforming. So, here is how to choose the best electroforming rectifier.

• Type of rectifier

You want your rectifier to be a DC power supply. It&#;s very important because direct current is what you need to plate your objects. Also, choose a rectifier that is adjustable and accurate, because you need to adjust your voltage precisely to get the wanted result. 

• Price

I personally think you do not need to buy a very expensive power supply, especially if you&#;re a beginner. You want your rectifier to last though, so I don&#;t recommend buying the first price either. If like me, you&#;re only using your power supply for electroforming, I suggest getting a rectifier between $50 and $100.

• Size and weight

Don&#;t forget to check the size and weight of your rectifier before you buy it. Especially if you have a small space to establish your setup. Most rectifiers are quite small and lightweight. They are easily portable and can be stored in any cupboard. I like that about mine, and I wouldn&#;t want to be bothered with a big machine.

• Power

If you plan on electroforming dozens of pieces at once, you might want to consider buying a powerful rectifier. Mine is 30V/5A and I plate up to 3 pieces at once with it. I&#;m sure you can do a lot more though. If you have a big bath, you might want to consider getting a 30V/10A power supply. 

• Ease of use

I had no idea how to use a rectifier before I got one. But since most of them come with instruction manuals, it&#;s not too hard to set up. However, I recommend checking reviews that mention the ease of use before buying. 

Electroforming rectifier: Buying guide

Here is a list of some pretty good electroforming rectifiers for beginners. I just want to mention that the power supplies I recommend are best for &#;hobbyists&#; or people like me, who enjoy making jewelry and selling it online. I do not mass produce, I plate around 10 pieces per week &#; sometimes less. If you want to plate hundreds of pieces at once and produce high volumes of electroformed objects, you might want to look at more powerful and more expensive rectifiers. With that being said, here are the best electroforming rectifiers for beginners:

The Eventek DC power supply is the one I&#;m currently using. It&#;s adjustable and can provide power up to 30V/5A. With this, you can easily electroform several pieces at once &#; I always electroform 3 at a time. This power supply is very accurate, and reliable. On top of that, it&#;s pretty affordable, small, and lightweight so it won&#;t take too much space in your home. Safe to use, this rectifier is FCC certified. Also, it has voltage overload protection and hot-circuit protection, so you don&#;t have to worry about using it for long periods of time. It&#;s super easy to use and comes with alligator clips. However, they are super small, but you can just get another pair if this is a problem for you. The Eventek DC power supply is definitely one of the best rectifiers for beginner electroformers.
