Silicone Casting Moulds

Our silicone casting moulds are available in a wide variety of sizes. They are made using (fully degassed) high quality addition/platinum cure silicone. Each mould is pressure tested to 70 psi. They all have straight sides and square corners. Each mould has a handy indicator line 5mm from the top of the mould to enable you to fill to the right level, you can also cast thicker casts by filling the mould to the top.

Due to their flexible nature our silicone moulds are easier to de-mould compared to HDPE moulds.

We would always recommend the use of a suitable mould release to help protect and extend the life of your silicone moulds and plugs, for more information here's a link to our Care And Instruction Sheets.

Any mould showing as 'out of stock' can still be ordered, and will be made, usually within 1-3 working days.
