To see these flexible options, please scroll down the the ‘Related Products’ section below.
Orders outside UK and EU
This kit cannot be purchased and shipped outside the UK and the EU because it includes our Copper Electroforming Solution (EU and UK only), one of our range of plating solutions that are regulated for transport.
If you want to purchase and have the Electroforming Kit – Copper kit delivered outside the UK and the EU then you could substitute this solution with our Copper Electroforming Solution (export outside UK and EU only). A link to this substitute solution can be found in the ‘Related Products’ section below this tabbed panel.
Spa Plating’s Electroforming Kit will deposit substantial layers of bright, smooth copper on most conductive and non-conductive surfaces with minimal post electroforming polishing required. Read HERE about how to prepare your item for electroforming using our Conductive Ink and how to set up your electroforming equipment. This kit is ideal for electroforming on plastic, including 3D printed plastic models, organic items such as seed pods and leaves and many other surfaces. Uses our easy to use single shot brightener system which means you can keep your solution plating bright with the minimum of hassle.
This kit (or any of our other kits, equipment or solutions) is not suitable for plating on to aluminium or titanium and therefore can’t be used to plate iPhones and other similar products.
To position the rod electrodes and anode bags correctly in the beaker, make sure that the anode bag is touching the bottom of the beaker and that the top of the anode bag isn’t touching the electrode ring.
One litre of our Copper Electroforming Solution is capable of plating 25 golf balls to a thickness of 100 microns.
Here are some exmples of SLA printed items, supplied to us by the RCA, which have been electroformed using our electroforming process. We recommend that only items printed with the stereolythic process be electroformed with our kit, rather than FDM.
A SLA printed cone-shaped item is being electroformed with the Spa Plating process. The cone needed to be selectively electroformed on the inside, so one of our rod electrodes with one of our anode bags was positioned on the inside. This demonstrates the unique flexibility of our process as it was posible to just grip one of our anodes in the plating arm and clamp and position it inside the cone.
A substantial thickness of copper has been electroformed on the inside of the cone.
This shows how an example plastic soldier looked to start with, then after spraying with our Conductive Ink (hi-grade) and finally after electroforming with our electroforming system. Click on the link to the right to find out about our ELECTROFORMING CALCULATOR and how it will help ensure you achieve a smooth layer of copper at the desired thickness.
Our electroforming kit is great for selective electroforming on glass.
This Electroforming Kit includes our MF Rectifier Mrk2. This power source can be used with our tank, brush and pen plating processes and is very straightforward to use. For instructions on setting it up for tank plating, please click HERE.
Once you have electroformed with copper, you can then use our brush or tank plating equipment to silver or gold plate on top.
All tank plating solutions need the occasional filter to keep them in good working order and this kit includes one of filter kits to keep your solution working at its optimum level.
In between uses of your electroforming solution, it’s a good idea to cover your solution with cling film to stop particles of duct and hair getting in as this will over time shorten the life of your solution. It will also reduce the frequency of having to filter your solution.

Made of non-corrodible metal
Will not rust and contaminate your plating solution
Has six threaded holes to securely hold six of our Rod Electrodes for 1 L Beaker
This allows you a high degree of flexibility. If you only have a small electroforming job, then you may only want to purchase 2 electrodes. Or you can buy the full set of six and arrange them according to the size and shape of the object you’re plating. Either way, you are ensuring you get the optimum performance from our Copper Electroforming Solution.
Hot Plate Stirrer
Fully variable heat control
Allows you to keep your Copper Elecroforming Solution at just the right temperature for optimum performance which is 22 degrees centigrade.
Copper Electroforming Solution is agitated with a magnetic stirrer at the bottom of the beaker during plating.
Mechanical agitation is a safer alternative to air agitation, as it eradicates any risk of the aerosol effect of the plating solution. Mechanical agitation keeps the Copper Electroforming Solution moving over the surface of the item being electroformed in a consistent way, again maximising the efficiency of the electroforming process.
Made from stainless steel
Will not corrode and contaminate gold tank plating solution. When used with clamp, can be moved up or down the stand in any position to fit any size of plating beaker.
Designed to be used with our Plating Arm and Clamp (sold separately)
Allows for complete flexibility – you can adjust height to of arms to accommodate small 250ml tanks up to and including 5 litre tanks
Electrical connection to work via negative lead, plugged into small socket at base of stand
Again avoids having to dangle work on negative lead directly into tank
Made bespoke from solid stainless steel and designed to be used in conjunction with the Plating Arm Clamp
Fully conductiveWill not corrode and contaminate the electroforming solutionWhen used with clamp, can moved up or down the stand in any position to fit any size of plating beaker.
Has ball head join point at one end to accommodate crocodile clip
Ball head allows complete 360 degree movement of crocodile clip, so you can quickly and easily make fine adjustments to the position of you work in the electroforming solution.
Plating Arm Clamp
Made in-house from non-corrosive stainless steel
Will not corrode over time and risk contamination of electroforming solution
Precision made from solid stainless steel to fit our Plating Stand perfectly, with wing screw for easy tightening
Means that you can fully adjust the height of the arm and it will be held firmly and safely in any position on the stand.
Temperature of solutions can be monitored by pointing the probe at the tank, pulling the trigger with the temperature shown on the LED screen.
The temperature of your plating solution can be quickly and accurately monitored without you having to submerge a thermometer into the solution, avoiding contamination of your plating solution.
Conductive Epoxy Filler
A two part resin that you mix together, that’s made of pure silver particles and becomes highly conductive once mixed
To be used to create a conductive join between two surfaces, for example attaching a piece of our Gold Plated Jigging wire to a plastic item before spraying with conductive ink to ensure there’s a good conductive join and electroforming will take place once suspended in the tank.Can also be used to fill in dents and holes before Conductive Ink spraying, to smooth out a surface.
Add small, millilitre sized quantities to you electroforming solution
Keeps the electroforming solution depositing bright layers over multiple uses.
You can work out exactly how much Copper Brightener to use by going to Electroforming Calculator, which you can find on any of our product pages or our Home page.
To work out how much Copper Brightener to add to your electroforming solution, enter in the surface area of the item you’re electroforming and the required thickness of electroformed layer, press the ‘Calculate’ button and the amount of Brightener will be displayed in millilitres.
Tests conductivity of Conductive Ink (hi-grade)
You can test to see how conductive the layers of conductive ink are that you have painted on, before you start electroforming. If the needle clearly moves, then it is conductive and you can go ahead with your electroforming
The polish that provides the greatest degree of cut that we sell.
Great for getting rid of defects in the base material and polishing back thick layers of copper plate before further layers of plate. If you intend to plate after using Autosol, you will need to go through the full cleaning process again.
All tank plating solutions occasionally need filtering to remove particles that build up over time. Our filtering kit makes the process of keeping your tank plating solution in tip top condition easy to set up and mess free. Added to this, regular filtering can help you save money by extending the working life of your tank plating solution.
A key feature of our kits is the flexibility to be able to customise them by removing items you don’t need or adding extra items from our product range. For example, you may already own a hot plate stirrer, or you may want to you downsize or upsize the plating beaker according to the dimensions of the items you wish to plate. The table below will help you do this.

Copper electroforming on plastic is now straightforward with our Electroforming Kit. When used with our on-line Electroforming Calculator, you can now electroform on to most non-conductive and metal surfaces to substantial and measurable thicknesses.
Unlike many other systems, you won’t need to do lots of post electroforming buffing and polishing, as our Copper Electroforming Solution plates consistently bright and smooth.
If the electroforming bath is likely to remain unused for long periods of time, the copper electrodes and Electrode Ring should be removed from the copper electrode bath and stored separately.
This project has four main stages;
1. Preparing the surface of the plastic model soldier to make it conductive with our Conductive Ink (hi-grade).
2. Preparing your electroforming equipment.
3. Electroforming in the Copper Electroforming Solution.
4. Post electroforming plating of silver and gold.
Please note: The Rectifier shown in this project has now been discontinued and replaced by the MF Rectifier Mk II.
Stage 1. Preparing the surface for electroforming
a) Mounting the model soldier
It’s important to mount you work well before starting as this will make surface preparation and electroforming much easier. Drill a small guide hole in an area where it can’t be seen. At this point it’s a good idea to calculate the surface area of your item, in preparation for entering the correct settings into the Tank Plating Rectifier later on. We estimated that this model has a surface area of approximately 20 squared centimetres.
Screw in a brass screw and then attach a small length of our Gold Plated Jigging wire to the other end. This will have two functions; it will form a conductive link between the object and the Copper Electroforming Solution and equipment, ensuring a good electrical circuit. It will also be able to be gripped securely in the crocodile clamp, making sure there’s no danger of your piece falling in to the electroforming solution.
We’ll be spraying on our Conductive Ink (hi-grade) to make the surface conductive and prepare it for electroforming. This could also be painted on.
b) Spraying on the lacquer
Spray the surface with a fine layer of clear lacquer that can be easily bought from any hardware or car accessory shop. We recommend using a solvent based clear lacquer spray.
The lacquer is an essential step as this forms a key layer for the next layer of conductive ink and in the case of porous materials such as wood, seals the surface. Wait for 10-15 minutes and once the lacquer is almost dry but retains a little stickiness, either spray or paint on our Conductive Ink (hi-grade).
c) Using an airbrush to spray on our Conductive Ink (hi-grade)
Charge your airbrush with our Conductive Ink (hi-grade).
Spray on a fine layer of our Conductive Ink (hi-grade). You only need a few drops of ink – just enough to cover the bottom of the airbrush well. Spray at a distance of 5-6 cm and apply only enough to block out the underlying surface of the object. One layer of ink is is usually enough.
Dry in an oven.
Leave in a fan oven at a temperature of 45-50 degrees centigrade for three hours.
Please note that this ink dries far quicker and harder at higher temperatures. However most plastics warp at temperatures in excess of 50 centigrade.
The temperature range for drying ranges from 45 to 80 degrees centigrade.
Stage 2. Preparing your electroforming equipment
a) Working out the amps for the MF Rectifier and electroforming times
First, work out the surface area of your work in centimetres.
You can then either enter this into the Electroforming Calculator, which you will find on our website and all the calculations will be done for you,
or you can do it manually. If you choose to do the latter, multiply the surface area of your work by the solution factor for the Copper Electroforming Solution, which is 0.05 For our plastic model soldier the calculation works out as 20 x 0.05 = 1.0, so the plating amps will need to be set to 1.0
Then you need to decide how thick you require your electroformed layer to be and therefore how long it should be electroformed. If you are electroforming an item that is quite fragile, you will probably need to build a fairly thick layer of copper. If this is the case, you should be aiming to leave it in the solution for about 2 hours minimum. Our Copper Electroforming Solution deposits copper at a rate of approximately 1 micron a minute, so after 2 hours you should have a layer of about 120 microns. This plastic soldier is quite rigid, so it will be electroformed for about an hour.
b) Setting up your electroforming kit
Fill the rinse beakers with tap water and turn the Hot Plate Stirrer on to its lowest setting so that the copper solution is being agitated. Make sure the temperature of the solution is in the range of 22-28 degrees centigrade. Plug one end of the black lead as shown into the front of the Tank Plating Rectifier and the other end into the base of the Plating Arm.
c) Setting the volts
Make sure the Output switch is open on your Tank Plating Rectifier and adjust the volts to 3 – 3.5
d) Attaching the red lead
Attach the red lead to the Plating Arm.
e) Closing the Output switch
Close the Output switch and adjust the amps to 0.5 to start with and then, once you’ve started electroforming, after about 15 minutes, you can increase it to the full 1.00 amps.
f) Open the Output switch
g) Attaching the red lead to the Electrode Ring
Attach the red leadto the Electrode Ring
Stage 3. Electroforming in the Copper Electroforming Solution
a) Placing your work into the solution
Lower your work into the solution and start the timer. Turn on Output and check that the amp level is correct; in this case with the plastic soldier it should be reading 0.5 to be increased after after 5 minutes minutes to 1.00
You should quickly see a layer of copper building on your item.
b) Finished electroformed soldier
When the time is up, remove your work from the electroforming solution and pass it through the two rinse beakers. As can be seen in the photograph, your work will be covered in a bright, shiny and substantial layer of copper that will require very little if any, polishing or buffing.
b) Electroforming on other non-conductive surfaces
The same sequence of applying lacquer, conductive ink and then electroforming can be used on natural materials such as shell, wood, stone and leaves.
If you intend to electroform on semi-absorbent surfaces such as wood you will need to apply at least 2-3 layers of lacquer to completely seal the surface.
For electroforming on shell, the surface of the shell must not come into direct contact with the electroforming solution as the solution will etch the shell, so every part of the shell must be covered in layers of lacquer.
If you want to electroform on glass, you’ll need to use our Glass Primer, rather than the spray on lacquer and then follow the same stages with the Conductive Ink. Please see our video on plating a glass plaque which can be found on the Glass Primer page on our shop and see the instructions for use on our online shop.
Stage 4. Brush or tank plating subsequent layers
a) Preparing the copper electroformed surface
Once you have a substantiallayer of electroformed copper on your piece and you have passed it through the rinse stages, you can now go ahead and plate other layers such as silver or gold. If you wish to gold plate, you’ll need to plate a barrier layer of white bronze or silver beforehand.
To prepare the copper electroformed surface for further plating, you can simply dip it into some Acticlean to restore it to that freshly copper plated look; you don’t need to use power via the rectifier.
b) Brush plating a silver barrier layer
The beauty of Spa Plating’s system is its flexibility. You can move seamlessly between tank, brush and pen plating once you have our Tank Plating Rectifier.
To brush plate a barrier layer of silver, set up your brush plating equipment as normal by attaching an electrode handle fitted with a platinum electrode to the red lead and grip a Conductor Strip into the crocodile clip on the black lead. Estimate how much Silver Brush Plating Solution you’ll need with the online Plating Calculator, then follow the instructions for brush plating silver that you’ll find in previous projects in this manual.
c) Gold brush plating
To gold brush plate the item, calculate how much gold solution you’ll need with our Plating Calculator and then refer to the previous projects that include gold brush plating for guidance.

If particulate contamination enters the solution, filter using our filter kit.
Please note that if using copper electrodes, continuous filtration will be necessary. If using
rod electrodes, the solution should only need occasional filtration if at all.
Brightener additions should be made at the start of plating if possible. Additions can
be determined using the Copper Electroforming Calculator by clicking Here
Higher temperatures favour less burning on exposed areas ie: sharp edges or pointed parts.
Solution should only be lightly agitated with the stirring rate set to minimum. Too much
agitation will disturb any copper residues in the anode bags causing them to enter the
solution which will produce a rough deposit.
