  • Preforming Thermoplastic Ducts
    Publication number: 20060273491
    Abstract: There are provided apparatuses and related methods for preforming sheets to form preforms for forming ducts. The preforms can be formed of a thermoplastic material, such as flat sheets of reinforced thermoplastic, which can be lightweight, strong, and perform well in flammability, smoke, and toxicity tests. The apparatus includes a heater for heating the sheet to a processing temperature and a structure for configuring the sheet to a desired shape of the duct. For example, rollers, rods, tubes, or a funnel can be used to bend the sheet.
