Vacuum forming is a simplified version of thermoforming, where a sheet of plastics (in various forms HIPS (High impact polystyrene) for low impact products, or for Bathroom shower trays ABS, and exterior vehicle parts HDPE, plus various other types of vacuum formable materials) is heated to a forming temperature, stretched onto a single-surface mould, and forced against the mould by a vacuum. This process can be used to form plastic into permanent objects such as turnpike signs and protective covers. Normally draft angles are present in the design of the mould (a recommended minimum of 3°) to ease removal of the formed plastic part from the mould.

Relatively deep parts can be formed if the formable sheet is mechanically or pneumatically stretched prior to bringing it into contact with the mold surface and applying the vacuum.

Suitable materials for use in vacuum forming are conventionally thermoplastics.

Thanks our special vacuum tank, Desert Star plastics can form parts with very small details.

Cost: it is divided in different sections

         1/ mold: the customer provides the mold or we make it

         2/ the vacuum box to be placed under the mold: standard or we do it

         3/ plastic: what kind of plastic (thickness, product) and quantity (each panel is always a little bit oversized for clamping)

         4/ the time for the set up

         5/ the time to mold each part

         6/the time to finish the part, meaning removing the extra plastic and cosmetic

On pictures, DSP displayed some parts done in polycarbonate (the clear and blue) and in abs (white and blacl)
