Generally speaking amorphous materials like polystyrene, ABS, polycarbonate, PVC, and PVC/Acrylic blends are easier to vacuum form as they do not have such a critical forming temperature. When heat is applied amorphous materials become soft and plia- ... Twin sheet forming has a lower tooling cost than blow molding and still produces a hol-
