The cheapest material, from which it is possible to make forms for forming products by the method of vacuum forming, is certainly MDF. We collect the required thickness of the future form from high-quality MDF boards and cut it on a CNC milling machine according to the previously designed 3D model. Then the surface of the mold is peeled and covered with the composition to avoid transfer of the roughness of the mold to the surface of the product. The next and final stage of production of the matrix for forming is the final grinding of the tool.
