Choosing the right thickness for silicone sheets in mold-making is crucial to achieving the desired results. The ideal thickness largely depends on the specific application and the type of mold being created.

For detailed and intricate molds, thinner silicone sheets, typically around 1mm to 3mm, are often preferred. These thinner sheets provide excellent flexibility, allowing them to capture fine details and produce highly accurate molds. They are also easier to manipulate and conform to complex shapes, ensuring that every detail is replicated.

On the other hand, for larger or more robust molds, thicker silicone sheets, ranging from 5mm to 10mm, are usually more suitable. These thicker sheets offer greater structural integrity and durability, making them ideal for molds that will be subjected to more stress or repeated use. They are less likely to tear or deform, ensuring the mold retains its shape and functionality over time.

In applications where both detail and durability are essential, a medium thickness of around 3mm to 5mm might be the best compromise. This thickness provides a balance between flexibility and strength, making it versatile for a wide range of mold-making projects.

Ultimately, selecting the right thickness for silicone sheets in mold-making depends on the specific needs of your project. By considering the level of detail required, the size of the mold, and the expected usage, you can ensure that your silicone molds are both effective and long-lasting.
