Twin Sheet Forming
The advantages of using twin sheet forming rather than blow molding or
rotational molding are cost and appearance related.
Twin sheet forming is a thermoforming process whereby two sheets of plastic
are
molded at the same time, creating hollow parts fused together into a structural
assembly. Different shapes and contours can be molded on opposite sides of the
part, along with differing color, material types and/or material thickness. By
injecting air pressure between the sheets, finite detail on the outer component
surface is realized (as with the pressure forming technique).
A wide assortment of materials are implemented but not limited to ABS,
Acrylic/PVC ,
Polycarbonate, Ultem, and TPO’s.
