Thermoforming and Vacuum Forming

Thermoforming and vacuum forming are often used synonymously, but it’s more accurate to say that thermoforming describes the general process of molding heated plastic materials, while vacuum forming specifies a process in which those materials are pressurized or vacuumed over a mold and cooled to retain their new shape.

While thermoforming and vacuum forming are not typically the best methods for mass production or manufacturing hollow parts, they are great choices for a variety of applications and rank highly among other plastic molding methods on affordability, speed, range across small and large parts, level of detail, and number of material options.

Why Choose Thermoforming?


Thermoforming is a fast alternative to many other plastic molding methods, such as rotomolding and compression molding. Custom part production takes a matter of days, rather than the months you might wait if using another method.


Plastic is more cost-effective than fiberglass or metal, and vacuum forming molds are relatively inexpensive, making thermoforming a much smaller investment than other forming methods.


Thermoforming can produce varied components in all sizes, from simple trays to highly detailed flight-critical components.


Plastics used in thermoforming can stand up to environmental pressures and resist degradation without regular maintenance.

Material Options for Thermoforming

  • ABS (Acrylonitrile Butadiene Styrene)
  • Acrylic (Polymethyl Methacrylate)
  • PETG (Polyethylene Terephthalate Glycol)
  • PP (Polypropylene)
  • PVC (Polyvinyl Chloride)
  • TPO (Thermoplastic Polyolefin)
  • KYDEX™ (PMMA / PVC blend)
