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, and that the second pre-stretcher is at least partially and moveably arranged in a second mold body. A movement relative to the second mold body and towards the same forming cavity of the first pre-stretcher, the second pre-stretcher, and the calibration element, can be individually controlled, and the second pre-stretcher at least partially surrounds the first pre-stretcher and the calibration element.

A system for preforming a sheet of plastic material (MP) including a first element forming a preforming cavity, the system including a second element adapted to be positioned opposite the first element, a set of pressing means sequentially actuated and carried by the second element to apply pressure locally to the sheet of plastic material (MP), so as to press this sheet (MP) against the first element, at least one means for sequential actuation of the pressing means.

A thermoforming apparatus includes a mold with a plurality of sections. Each section is independently movable. The thermoforming apparatus further includes a set of electromechanical actuators. Each electromechanical actuator is attached to a screw that moves each section of the plurality of sections to specific positions. The mold is configured to press against a blank to form a product with a shape corresponding to the specific positions of the plurality of sections.

The present disclosure provides a negative mold for luggage molding and an application thereof. The negative mold includes an upper mold holder (11), a convex mold (12), a lower mold holder (21), a concave mold (22), a lifting platform (23), and a material frame (31). The upper mold holder is arranged with a first airflow channel (111); in the adsorbed state, the upper mold holder abuts against the material frame to define an upper air cavity (112); air is blown downward through the first airflow channel to stretch the sheet (41), while each of the convex mold and the concave mold moves in a direction close to the sheet to define a molding space; in the mold detaching state, each of the convex mold and the concave mold moves toward in another direction away from the material frame to detach the molded sheet.

An apparatus for skin application of a thermoformable film (9) to a support (3), comprising a supporting element (4), defining a working chamber (6) for receiving a support (3), and a closing element (5), which has a lower heating face (8). The supporting element (4) and the closing element (5) are movable between a home position, in which the working chamber (6) is open, and a working position, in which the upper opening (7) is completely closed by the lower heating face (8). The supporting element (4) comprises a housing portion (15), defining a housing (19) for the support (3), a distancing portion (16), between the housing portion (15) and the upper opening (7) and defining a distancing space (21) interposed between the housing (19) and the upper opening (7), and cutting means (23) which surround the housing (19).
