Mold calculator
Use it when you need to know how much silicone or rubber to buy to make a mould.
- Block mould: enter the dimensions of the container (the box where you are going to pour), subtract the volume of the original and the result is the silicone you need. You can measure the volume of the original by submerging it in water and measuring how much the level rises.
- Brush-on mould (blanket): enter the approximate surface area of the original, the number of layers and the thickness per layer. For fluid platinum silicones, 3–5 mm per layer is recommended; for thixotropic ones you can reach 6–8 mm.
- Select the material from the dropdown: the ratio and density load automatically. If your product is not on the list, use «Other» and edit the values manually.
Casting calculator
Use it when you have a mould ready and need to know how much resin, rubber or foam to buy to fill it.
- By dimensions: si tu molde es una forma regular (cubo, cilindro simplificado…), enter length × width × height and the calculator estimates the volume.
- Direct volume: if you already know the volume of the mould (e.g. you have measured it by filling it with water), enter it directly en cm³.
- The result includes the breakdown into component A and component B according to the product ratio, ready to know which format to order.
It is always better to have too much than too little. Running out of material halfway through a pour or with the mould half-filled is one of the most frustrating mistakes — and it usually means scrapping the entire piece. Density values are indicative and may vary with temperature, batch or technique. Use the safety margin (we recommend at least 10–15 %) and, if in doubt, go up a size in format. Leftover material, properly sealed, keeps for months.
