Our Vacuum Thermoforming machine uses thermoplastic sheets up to 48″ x 72″ and up to 1/4″ thick. Tooling area is 43″ x 67″ with a 20″ draw. Mold Options: Molds can be 3D printed for fast part production or machined out of tooling board or aluminum for higher quantities. Thermoforming is commonly divided into two categories: vacuum forming and pressure forming. In vacuum forming, the hot plastic sheet is pulled against the contours of the mold by vacuum pressure. Since pressure is only applied to one side of the sheet, vacuum forming is typically selected for parts that are relatively simple in design and that ... Polycarbonate / Lexan Thermoform Plastic Sheets Polycarbonate (often sold under the trade name "Lexan") is the virtually unbreakable thermoform plastic used to make bulletproof glass. Thin-gauge, transparent Polycarbonate is the material of choice for folks who build ultra light, thin plastic parts that are exposed to a lot of abuse. With the thermoFORM system, Polycarbonate plastic sheet is heated to a pliable forming temperature and shaped in a mold. The Polycarbonate Bundle Pack includes multiple 12x12" sheets of white Polycarbonate clear plastic in a thickness of 0.060", perfect for use with the ThermoFORM Vacuum Forming System.
