SPM Vacuum Forming Machine

Vacuum forming is the simplest type of plastic thermoforming, that uses one mold and vacuum pressure to obtain the desired part geometry. It is ideal for parts that only need to be precisely formed on one side, such as contoured packaging for food or electronics.The process involves heating a plastic sheet until soft and then draping it over a mould. A vacuum is applied sucking the sheet into the mould. The sheet is then ejected from the mould.Vacuum forming takes its name from the fact that a vacuum is used to form a sheet of plastic into a desired shape. It is popular within various industries and sectors because it can produce detailed shapes quickly and affordably.The machine used in vacuum casting allows the duplication of plastic parts using a silicone mold. It has a depressurized chamber to prevent the insertion of air bubbles on the surface of the prototypes. This machine makes it possible to produce parts made of polyurethane (PU) resins simulating the real material.
