Thermoforming

Thermoforming, sometimes refered to as vacuum forming, is efficient and very cost-effective for the production of many plastic parts depending on their size, shape, and quantity.  Initial project costs are usually much lower, and lead times to tooling and production are generally much shorter than injection molding.

Thermoforming is a great way to get started manufacturing plastic parts.  Let us be your supplier with our 3 thermoforming machines.

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.
