A thermoforming mold device (1) providing a piece with a thin wall starting with a sheet of thermoplastic material is provided. At least one (3) of two parts of the mold (3, 3) comprises at least one means (4) of local deformation of a sheet (2) in the mold (3, 3) in its closed state, the at least one means (4) comprises a piece of hollow molding with a peripheral edge, which can be connected selectively to a source of suction and can be displaced between a folded position, in which the molding piece is situated in close proximity with the wall of the thermoformed piece, and a deployed position, in which the molding piece is applied under pressure with its peripheral edge against the wall of the thermoformed piece upholding the other part of the mold.

THERMOFORMING ASSEMBLY

A thermoforming assembly includes a lower mold part (20) and an upper mold part (34). The two mold parts are able to move in a substantially vertical direction between an open position and a closed position. Retaining members (28) are able to hold a sheet of softened thermoplastic (10) in a substantially horizontal mean plane Pm between the two mold parts. The retaining members include a plurality of rods (28) mounted mobile in the lower mold part (20). The rods (28) project out from the lower mold part (20) when the two mold parts (20, 34) are in the open position, to hold the sheet of softened thermoplastic (10) in the substantially horizontal mean plane Pm and accompany it as the mold closes.

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.

SYSTEM FOR PREFORMING PLASTIC SHEETS

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.

THERMOFORMING PROCESS WITH A REFORMABLE MOLD

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.
