  • Publication number: 20200156305
    Abstract: A method for the crystallization of a film made of a thermoplastic film material, in particular a CPET material, to form a product in which a crystallization process is initiated by shaping the thermoplastic film material within a molding tool. A main crystallization of the crystallization process is carried on outside of the molding tool.

  • Publication number: 20190160725
    Abstract: A thermoforming device is described. It relates to a mold assembly including a first and second mold, and to a mold that can be used in a thermoforming device. It also relates to a method for thermoforming a product. The thermoforming device is characterized in that the thermoforming device comprises a second pre-stretcher, in addition to a first pre-stretcher and a calibration element (19, 20), and that the second pre-stretcher is at least partially and moveably arranged in a second mold body (12, 43). A movement relative to the second mold body (12, 43) and towards the same forming cavity of the first pre-stretcher, the second pre-stretcher, and the calibration element (19, 20), can be individually controlled, arid the second pre-stretcher at least partially surrounds the first pre-stretcher and the calibration element (19, 20).

  • Patent number: 9840036
    Abstract: A thermoforming machine and device are described. The thermoforming device relates to a mold assembly comprising a first and second mold, and to a mold that can be used in a thermoforming process. A method for thermoforming a product is also described. It is noted that the thermoforming device comprises a second pre-stretcher, in addition to a first pre-stretcher and a calibration element, and that the second pre-stretcher is at least partially and moveably arranged inside a second mold body. Movements of the first pre-stretcher, the second pre-stretcher, and the calibration element are configured to be individually controlled.

  • Publication number: 20170348896
    Abstract: A method for producing a thermoformed product on a single machine with several stations and with different tools includes the following steps: (a) melting and homogenizing plastic granules and providing the plastic melt at a preform station; (b) producing a preform at the preform station in a preform cavity; (c) transferring the preform by a transfer carrier to a thermoforming station at the same machine, the thermoforming station having a thermoforming tool having a thermoforming cavity; (d) preferably heating the preform during the transfer; (e) thermoforming of the thermoformed product in the thermoforming cavity. Advantageously, the final thermoformed product is produced directly from the plastic granules using only a single machine, and in particular without any waste, when the preform is dimensioned in such a way that it does not present any excess with respect to the final shape of the product to be produced.
