Vacuum forming or thermoforming is one of plastic processing technologies. At the same time, it is the oldest and most used method. The material is shaped on the form using vacuum. This means that the basic material after heating replicates the shape of the form (which has a form of the final product), using physical and mechanical properties of thermoplastic substances, which change their shape and return to solid condition when cooled. The advantages are lower costs for mold production, fast production preparation, spatial product shape, high detail, possibility of blister production and suitability for serial production. Vacuum forming is used to produce a wide range of products.
