Prototypes and permanent molds are substantially less expensive than injection molds.
Better Physical Properties In Finished Part
In thermoforming, the heated sheet is virtually stress free compared to other polymer manufacturing methods. When properly formed, the sheet is stretched at the forming temperature before it is cooled against the mold. This sets up a very minimum of internal stress in the finished part.
Ability To Take Advantage Of Multiple Layer Sheet Material
Thermoforming technology makes full use of multiple layer sheet material. Decorative and/or weather resistant caps can be applied to the extruded sheet prior to forming.
This combines a strong impact resistant substrate with a functional and highly cosmetic surface.
Pressure Forming Fine Detail
A thermoforming process similar to Vacuum Forming, with a pressure assist forcing the material to conform to every detail of the mold.
Ability To Form Very Large Parts
Relative to other processing methods, part sizes up to 5 ft x 8 ft (1.524 x 2.44 m) can be thermoformed easily and economically.
