Product Description

If you want to start making your own carbon fibre parts the first thing you'll need to do is make moulds for the parts you want to make. If you're new to composites this can be a daunting task and for this reason we have put together a comprehensive mould making kit which makes use of brand new materials and techniques to make the process of making high quality moulds as quick, easy and clean as possible.

Included in the kit is 750g of special mould making 'putty', epoxy resin tooling gel coat, their appropriate hardeners, a tin of wax and some gloves. This amount of putty and gelcoat is sufficient to make a sufficiently strong mould of about 30cm x 30cm, depending on the shape of the mould.

What is this putty?

The mould making putty in the kit replaces the need for chopped strand mat (unwoven fibre glass mat), polyester resin and catalyst normally used in fibreglass mould manufacture. The reason for doing this is that polyester resin and its catalyst are both rather nasty to work with and very difficult to ship. For making smaller parts especially, this new putty material is a fast, clean and highly effective way of making moulds requiring no prior fibreglass experience. Because of the way the putty is ‘formed’ into shape, it avoids the pitfalls of air-voids and blisters that can blight early mould making attempts with traditional fibreglass.

In the kit is a plastic container with 750g of slightly fibrous putty. With gloves on the putty can be handled, pulled apart and pushed back together with ease. Also in the kit is a small container of hardener for the putty which is darkly coloured. With the right amount of putty in your hand for the job you add the appropriate amount of hardener and mix the two materials together thoroughly. The putty is then shaped over and around the gel-coated pattern/part to form the body of the mould. A thickness of 1cm of putty for a small part or 2cm for a larger part would make for a strong durable mould. The process is clean and odourless.

Comprehensive Instructions

As with all Carbon Mods starter kits, the mould making kit is accompanied by comprehensive instructions that take you through the process of skinning your parts from prep all the way to polish.

could i use it to cover a platic shell of a RC car and then take the plastic out so only the carbon stays
Carbon Mods Reply: Well, this page is a listing for the Mould Making Kit. You could use the plastic shell of an RC car as the pattern for a mould made in the way shown on this page - what you'd be left with is a mould ready to make your own carbon fibre shell.

Hi, just a suggestion to avoid the music on the videos. It only creates noise and makes it harder to understand the narrator. Cheers
Carbon Mods Reply: Agreed. Our new videos don't have any music!

Q. How do I achieve that gloss finish? You mention using 1200 grit sandpaper. Do you start coarser sandpaper?

A. It's important to get the finish you want your mould to have on your part already (where possible). You normally wouldn't do much polishing on the mould, if the part was shiney, your mould will be shiney. You would only start with a coarser abrasive paper if you had coarser stratches or blemishes to get rid of.

Q. What is that liquid you add to the sandpaper in the video?

A. That's just water. You use it to stop the paper from clogging.

Q. What is that last step where you seem to apply something with a piece of cloth?

A. That's polishing compound. It's inlcuded in the kit. It's a fast cut compound that's specially developed for composites.
