Thermoforming

Thermoforming is a process of taking a flat sheet of heated pliable plastic and conforming it to a mold.  Sometimes referred to as vacuum forming, it is an efficient and cost-effective way to produce many different plastic parts depending on the size, shape, and quantity.

Thermoforming is an excellent way to ge manufactured plastic parts.  Initial project costs are usually much lower than injection molding, and lead times to tooling and production are generally much shorter than injection molding.

How does Thermoforming Work?

  1. A flat sheet of plastic is heated until it is soft and pliable.
  2. The sheet is lowered on to the mold.
  3. The air is vacuumed out of the voids and the sheet conforms to the mold.
  4. The mold cools the material until it "freezes".
  5. The mold is lowered from the cooled part.
  6. The excess material is trimmed using a secondary process.
