Using vacuum forming products can help us to make many interesting works. The operating principle of the vacuum forming machine is that the flat plastic sheet is heated and softened, and then it is adsorbed on the surface of the mold by vacuum. After cooling, a shape of the model will be formed. Vacuum forming products can be used in schools such as STEM education, lighting, desserts and chocolate mold, product design and other industries. When it used in conjunction with a 3D printer, you can create more variety.
