During thermopressing the foam is heated on both the top and the bottom side, then pressed from both directions by a cooled two-part mold, and then released. It is possible to make foldable products with it, or to give very deep patterns to the surface.

The main difference between embossing and thermopressing is that with thermopressing the heating and cooling takes more time, but because of the more thorough heating, much deeper patterns are achievable than with embossing. This also means that thermopressing is a slower process.
