Industrial Processes-Vacuum Forming

A Vacuum Forming Machine Vacuum Forming Vacuum Forming is an industrial technique which may be used for batch production or mass production. A sheet of thermoplastic held by the use of toggle clamps is heated until the plastic becomes malleable (soft and flexible). The air is then sucked out from underneath the plastic using a vacuum pump. Atmospheric pressure presses down on top of the plastic sheet which in turn presses down onto a mould or pattern. The plastic sheet takes the shape of the mould. This process enables thermoplastics to be formed into complicated shapes such as packaging, storage trays and seed trays.

Programmes of Study 4c A range of industrial applications for a variety of familiar materials and processes; 5e That to achieve the optimum use of materials and components, account needs to be taken of the complex interrelations between material, form and intended manufacturing processes.
