Making your own silicone bait moulds

I have been having a play with making my own lure molds for a while now and had some success with them. I thought it was time to make some more as I wanted to try a different style lure and I also wanted to show you how I make a sweetcorn mould too.

The first thing you will need to do is make yourself a mould template, there are lots of ways to do this but if you don’t mind remaking the templates then the cheapest way to do this is as follows…

You will need some hard cardboard such as that you find on the back of an A4 writing pad, a pair of scissors, some duct tape, a square ceramic tile and some playdough.


On the ceramic tile create the lures that you want to use out of the playdough making sure to leave a space between each lure and also the edge of the tile. (a reusable template can be made using modelling clay and either oven bake or air dry work well)

Next create a tight fitting wall of cardboard around the edge of the tile, securing it in place with the duct tape and that is your lure mould template complete.

For this next part you will need a good quality two part silicone. I get mine from EA Silicones as it is a good value quality product and their service is exceptionally good. The silicone I use is the RTV2015 which is specifically designed for mould making. It is an industrial product and not for preparing food, you can however use RTV1015L which is food safety approved.

The kit comes as two parts firstly the liquid silicone and secondly the catalyst. Mixing couldn’t be simpler, if you are using the whole tub simply tip the catalyst in to the tub and then stir carefully until it is thoroughly mixed together.

Once your mix is ready, carefully pour it over the centre of your mould and slowly work your way around the mould allowing the mix to cover your lure template by around one centimetre.

Leave your mould to set at room temperature for 24 hours, then remove the cardboard from around the edge of the mould and carefully lift the mould off the ceramic tile.

You will now need to gently remove the playdough from the mould and clean any playdough out of the mould that gets left behind.

You now have a few choices on what to make the lure from, you can use a product called plastisol which is basically liquid plastic which you microwave to create the reaction to make it set.

However I much prefer using gel which isn’t as permanent but can be flavoured and will also dissolve if left in water over a period of days. You can make your own gel using the instructions and recipe in one of my previous blogs “Biodegradable Plastic” or you can do what I have done for this blog and buy a gel powder from Fritz Germany.

Making up the gel powder is easy as it is one part gel powder to two parts warm water (boil a kettle and leave to stand for three minutes to give you the perfect temperature water). The gel powder isn’t shelf life so I also add 5g potassium sorbate granules per 20ml of water used.

Then use a syringe to fill the moulds with the liquid gel and allow to cool for about 45 minutes. (less if you put it in the fridge)

To make a sweetcorn mould is exactly the same method but roll out your playdough to the thickness of the sweetcorn you want to make.

Next cut it into squares approximately the size of the corn you want to make.

Then place the squares with a small gap on the ceramic tile and carefully shape into a sweetcorn shape. Then simply carry on with the process as before.

Well I hope you have enjoyed this blog and found something useful from it.

Till next time,
Tight lines and happy experimenting.
