Providien has been a world-leading thermoformer of highly aesthetic, complex medical device enclosures and other plastic products for over 40 years. These decades of experience have helped to make Providien a trusted and competent source for your company’s twin sheet thermoforming needs.
In a twin sheet thermoforming process, two separate sheets of material are heated simultaneously. One sheet is drawn into a top tool and the other sheet is drawn into a bottom tool using a vacuum process. The tools are then brought together and pinched around the perimeter of the part. Air pressure is applied between the sheets, pressing each sheet into its respective tool. The result is a hollow part that is structurally rigid and cosmetic on both sides.
Parts that need to be controlled and/or cosmetic on both sides are ideal candidates for the this process. Doors, panels and lids are great examples of these types of parts. An additional benefit of is that they dampen noise and can act as a thermal insulator.
