The silicones for molding will allow you to work with different materials and make fully customized shapes, the molds can be used to create your own molds for edible products, such as cookies, chocolates, ice cream, etc., as well as for molds for hygiene products (soaps), decorative and handicraft pieces, jewelry and much more.
Silicone putty for molds
TheSilicone puttyFor molds is ideal for use alone or with different materials:
Among the components that you can use with silicone are wood, ceramic or plaster.
But you can also use it alone to make molds that can be used to work with soaps, candles, plasters, resins, etc. Transformable materials in general. By making your own mold you will be able to create your own figures and shapes totally personalized and to your liking.

Sale of silicone for molds, we offer you different types
Low hardness silicone
Thelow hardness silicone,Although it has that name, it is a very resistant material, so it will be ideal for working with more complicated products, both chemically and mechanically. In addition, it will allow you to manufacture a large number of parts per mold thanks to its durability.
Thanks to this silicone you will be able to create a very elastic mold, which will allow you to demold complicated and elaborate figures without the risk of breaking them.
Undoubtedly one of the best silicone options in terms of value for money, as it is an "inexpensive mold silicone" compared to all the benefits you will get.
Platinum Silicone Mold Silicone
This type of silicone will allow you to work with different materials and create a large number of molds and parts. In addition, they are very resistant (even creating thinner molds), thanks to their great resistance to corrosive products, humidity and prolonged use.
EASYPLAT will also help you to increase the life time of your molds, as it always maintains the softness of the silicone, so your parts are always perfect.
Silicone of tin for metals
This type of silicone is characterized by its high quality of hardness, so it will allow you to work perfectly with very complicated materials that require to be worked at high temperatures, such as low melting point metals.
Thismetal siliconeHas a low mixing viscosity and when cured you will not have to worry about any noticeable shrinkage. It also has a much higher tear strength than other low melting point metal silicones on the market.
Silicone Food Safe
Food silicone as theEasyl 940-FDA, is undoubtedly the most specialized silicone for molds in this area, as it is perfect for use in food products (making chocolates or cakes, candies or other sweets, ice, etc.)
Food grade silicone is a type of platinum silicone that is very easy to manufacture and will allow you to make fantastic molds to your liking (always being careful with the products you use and maintaining the safety rules for platinum silicones).
In addition, this type of material, specifically for the food industry, has excellent thermal resistance (220 Cº) and negligible shrinkage.
It is a product that also has a very low viscosity, which makes it flow very well to make the mold and leaves practically no bubbles.
How to make silicone molds once you have chosen the silicone?
-
The first thing you need to make a silicone mold is to have a figure that will serve as an example and a container with the appropriate size (that fit in it the chosen figure and the mass of silicone, having a certain distance between them and the walls of the container), try that this container is metal or plastic and that has the right size.
Our recommendation is that you use a relief figure that is not too complicated or too nuanced to produce a perfect mold.
-
Then apply release agent to both the container and the figure. This is important, because if either of the two is porous, especially the figure, this will cause the silicone to penetrate and it will not be possible to demold it, and you would risk damaging the figure and the container.
However, one of the great advantages of silicone is that most of the time it does not require the application of release agent, since this will only be necessary if there is a lot of pore.
-
Next, read the instructions on the silicone molding package carefully (as each product has specific specifications) and prepare the materials to make the mold.
-
Mix well and be careful to seal the base well; let it dry for a while and then fill the rest of the container completely.
-
Once done, let the mold dry for 24 hours and, after this time, carefully demold it using a knife or your hands.
If you use food grade platinum silicone, once the mold has cured and 24 hours have elapsed, you will need to clean the inside of the mold with dishwasher before placing any food.

Preguntas frecuentes
What's the difference between platinum silicone and tin silicone?
Platinum silicones (addition) offer greater dimensional stability, are translucent and skin-compatible. They're ideal for prosthetics, lifecasting and high-precision molds. Condensation silicones (tin), like EASYL 3520 or EASYCLEAR, have very good value for money and are perfect for polyurethane and epoxy resin molds, although they shrink slightly over time and require mold release.
How do I choose the correct Shore hardness for my mold?
It depends on the geometry of the piece. For originals with lots of undercuts, choose a soft silicone (Shore 00-30 or Shore A10-A20) that deforms easily when demolding. For flat molds or with little relief, a Shore A25-A40 hardness offers more rigidity and withstands more pours. As a reference: EASYPLAT 00-30 (Shore 00-30) is very soft for prosthetics, while EASYPLAT MOLD-40 (Shore A40) is harder and more resistant.
Can silicone be used on any surface?
Most condensation silicones work on almost any surface with proper mold release. Platinum silicones, on the other hand, can suffer cure inhibition if the original contains sulfur (sulfurous plasticines, latex, tin rubber or certain adhesives). If you're unsure, always do an inhibition test on a small area before pouring the complete mold.
How many uses can a silicone mold withstand?
A well-maintained silicone mold can withstand between 25 and 100 pours or more, depending on the material you pour and how you treat it. With polyurethane or epoxy resins, cleaning well between pours and using mold release greatly extends its life. Platinum silicones tend to be more durable than condensation ones, which can degrade faster with aggressive solvents.
Can silicone be pigmented?
Yes. You can add silicone-specific pigments before mixing the two components. At Feroca we have pigments like Neill Gorton's Key-Pigments and the DYE PLAT range, formulated for platinum silicones. Never use acrylic or water-based pigments: they can inhibit cure and ruin the mold.
Is silicone suitable for food use?
Not all silicones are. For pastry, chocolate or candy molds you must use food-certified references. At Feroca we have Easyl 925-FDA and Easyl 940-FDA, which comply with FDA regulations and withstand temperatures up to 220°C. The rest of the silicones in the catalog are not certified for food contact.
