Vacuum forming

Vacuum forming is a typical example that benefits from advantages of Atlas Copco GV series of vacuum pumps. Although products frequently applied in this process are small vacuum pumps, as the size of vacuum forming products become increasingly large, more and more adjustable cental vacuum system is being used in relative process.

Vacuum Forming
In its simplest forming process consists of inserting a thermoplastic sheet in a cold state into the forming clamp area, heating it to the desired temperature and then raising a mould from below. The trapped air is evacuated with the assistance of a vacuum pump and once cooled A low pressure compressed air supply is applied to release the plastic part from the mould.

In its advanced stage pneumatic systems complimented with sophisticated heat and process controllers allow high speed and fast cycling with accurate vacuum level control being needed to satisfy heavy duty and high end volume applications.
