Twin Sheet Thermoforming is a plastic manufacturing process where two sheets of material are heated and formed simultaneously into their respective molds and then quickly pressed together.  While they are being pressed together, a pin is pushed through one of the sheets and air is blown in causing the sheets to be pressure formed.  The heat and pressure cause the 2 sheets to fuse or seal and become a single unit where they are touching and allow the parts to be trimmed completely flush all around.  This creates an extremely strong, rigid part. Products manufactured with the twin sheet thermoforming process may look similar to blow molding or rotational molding but are often less costly to form, and can be highly cosmetic.
