Silicone molds are easy to use and very versatile, but the final results depend a lot on how they are used. Many defects occur not because of the mold, but from wrong steps in the casting process.

In this article we present the most common mistakes when using silicone molds and how they can be avoided for clean and consistent results.
Choosing the wrong mold material
One of the most common mistakes is using a material that is not suitable for the type of mold chosen. Molds with fine details or complex shapes require materials that:
-easily penetrates the mold
-does not force the silicone when demoulding
-allows uniform hardening
Using the wrong material can lead to loss of detail or damage to the mold.
Casting at incorrect temperatures

The temperature of the material when casting directly influences the final result. If the material is:
too hot → may affect the elasticity of the silicone
too cold → will not fill in details correctly
Adhering to the recommended temperatures is essential for optimal results.
The appearance of air bubbles
Air bubbles are a common problem, especially in molds with fine details. They usually occur due to:
-rapid casting
-lack of vibration or mold leveling
-lack of air removal before hardening
Light spraying with alcohol and slow pouring can significantly reduce this risk.
Demoulding too quickly
Rushing is another common mistake. If the product is not fully cured:
-the edges may deform
-details can break
-the matrix is ​​unnecessarily forced
It is important to respect the recommended curing time before demoulding.
Forcing the mold when removing the product
Silicone molds are flexible, but should not be handled aggressively. Repeated forcing can lead to:
-loss of elasticity
-breaking thin areas
-loss of details over time
Demoulding must be done gradually, from the edges, without jerking.
Conclusion
Most problems encountered in using silicone molds can be avoided by paying attention to detail and following the correct molding steps. Choosing the right material, controlling the temperature, and properly demoulding contribute to achieving successful products and keeping the mold in good condition over the long term.
