Plastitel’s US patent 7665982 B2 is a crowning achievement in their development efforts for a unique production method.
It consists of inserting a component between two plastic sheets during the molding process: metal structure, foam insulation, mechanical inserts, etc.
Different parting lines are also possible: horizontal or vertical.
The size of the parts that we can mold for the twin-sheet process can reach 4 feet x 8 feet, with a depth of up to 48 inches (2 x 24 inches).
For twin-sheet molding, Plastitel can thermoform plastic sheets of different thicknesses, from .060 up to .250 inches.
We thermoform plastic parts by twin-sheet molding with negative-draft, undercut areas.
Tool manufacturing is often very complex in order to achieve these results.
