This Expansion Box allows you to run multiple brush plating processes at once, without having to stack your leads at your rectifier. It also has a handy ‘Strip up/Plate down’ switch, which makes chrome stripping much easier to manage.

Mounting your Expansion Box on the underside of workbench makes running multi-stage brush plating runs much smoother as it gets rid of trailing wires. For illustrated instructions for fitting your Expansion Box, please click HERE for our Electroplating Manual.

Expansion box plugged straight into rectifier

Features Used for
Three positive output sockets Plugging in three electrode handles and electrodes at once, without having to ‘stack’ your leads; allows you to move seamlessly through a multi-stage brush plating process
Strip up/ Plated down switch Quickly reversing the current for chrome stripping. Means you don’t have to un-plug and plug back in the leads to reverse the current, saving time and hassle
Flashing red light Warning you that you are in stripping mode and that you’ve reversed the current. This stops you from damaging your work by forgetting to reverse back the current before proceeding with the next plating stage, after chrome stripping
Wall mountable Can be mounted on the underside of your bench, to make it even easier to use. For instructions on this please see our manual.


Fitting our Expansion Box for Brush Plating

To get the most out of your expansion box we recommend you fit it permanently to the underside of your bench. You’ll then be able to move seamlessly from one plating stage to the next, without having your leads trailing over your plating trays. Instead, they’ll be neatly stored under your bench and because the box is fixed at waist height, reaching the switch to reverse the current for chrome stripping will also be much easier.

Expansion Box in detail

Our Expansion Boxes allow you to change from strip to plate at the flick of a switch – no more swapping over leads at the rectifier! As well as this, the flashing red light helps you to avoid damaging your work by warning you that you‘re in stripping mode. This avoids one of the most common mistakes in brush plating, where the operator starts the electro-activation/cleaning stage with the electrical current flowing in the wrong direction because they’ve forgotten to reverse the current.

Fitting instructions for the Expansion Box

1. Disassembling the expansion box

To fix your expansion box to your bench, you’ll first have to take the front plate off. Just remove the four screws from the corners of the front plate with a phillips screwdriver.

Here’s how the box should look when you’ve taken it apart.

2. Marking the position of the drill holes

To fix the expansion box to the bench, you’ll need to use screws. In this case we want to attach the box to the underside of the bench top, so the drill holes should go on the top of the box.

3. Drilling the holes

When drilling the holes, try to make sure you’re supporting the box on an even surface.

4. Attaching the box

Position the box carefully and fix to the underside of the bench.

5. Reassembling the Expansion Box

Put all of the contents back in and replace the screws.

6. Connected Expansion Box

The Expansion Box is now connected to the full set of wands and the rectifier, showing just how useful the box is in organising your work area. If you want to place the rectifier at any distance from the Expansion Box, you’ll need to fit a couple of our extension leads, which you can get from our website.
