Twin Sheet Thermoforming Process: The top sheet is drawn into the top mold and the bottom sheet is drawn into the bottom mold. The two molds are pressure welded together at designated points around the perimeter. Twin-sheet thermoforming produces double-walled parts, panels and components. In general, thermoforming involves a single or multi cavity mold, an ability to draw vacuum on the mold, and a means of heating thermoformable material to its softening point. Variations include drape forming, plug assist forming, pressure forming, twin sheet forming, etc. Twin Sheet forming Twin Sheet Forming uses distinct top- and bottom molds, heat, and vacuum to create a void between two sheets of plastic while forming a strong edge seal. Founded in 1963, C+K Plastics is recognized as one of the most experienced, state-of-the-art, thermoforming companies in the industry.
