A method for manufacturing a part for an aircraft seat includes positioning a heating frame around a stacked structure, locally heating an edge of the stacked structure using a heating frame, externally heating the entire stacked structure, positioning the stacked structure inside a thermoforming mould provided with cutting punches, closing the thermoforming mould and applying a vacuum to the interior of the thermoforming mould, to simultaneously perform, during the same step of shaping the first cover and the second cover, a step of heat sealing an edge of the first cover to an edge of the second cover, bonding the first cover and the second cover to the foam core, and cutting the stacked structure along the circumference thereof using cutting punches.

The present application relates to a thermoforming device. According to an embodiment, the thermoforming device includes a gaseous medium damper for damping a relative movement of the lower mold and the upper mold and/or a gaseous medium damper for damping a relative movement of the lower mold and the ejector plate.

Apparatus and methods of forming sheets of material are disclosed. Profile plates may be placed atop the sheets. Tabs attached to clamp frames may apply uniform pressure on the perimeters of the profile plates during the formation process.

A forming tool is used, which has a tool trough arranged in a stationary manner and a pressure bell, which can be lowered onto and lifted away from the tool trough. An arrangement is created in which a single- or multi-layer, initially flat, flexible laminate separates the trough interior from the pressure-bell interior in a pressure tight manner. A table, on which the 3-D substrate to be coated is located, assumes a lowered position within the trough interior; there is a considerable, free intermediate space (between the laminate and the 3-D substrate. A radiant-heater assembly is inserted into said intermediate space. The radiant-heater assembly has a carrier, on the top side of which radiant heaters that can be activated are attached and on the bottom side of which radiant heaters that can be activated are attached.

A method for making a structural sandwich panel includes the steps of positioning a first and second thermoplastic skin elements in overlying relationship with respect to a heated male and heated female die molds respectively. A first pressure reduction is applied between the first thermoplastic skin element and the heated male die mold and a second pressure reduction is applied between the second thermoplastic and the heated female die mold. A core panel element is positioned between the heated male die mold and the heated female die mold wherein the core panel element has a first adhesive on a first side and has a second adhesive on a second opposing side. The male and female die molds are closed and exert a pressure onto the core panel element to secure the first and second thermoplastic skin elements to the core panel element and form the core panel element.

Pot with an undercut that includes a bottom wall (5), a side wall (6) that is closed on itself and connected to the bottom wall (5), with an opening providing access to the interior of the pot. The outside surface of the side wall of the pot has a non-symmetrical undercut shape for rotation around the vertical direction (Z). The outside surface has at least one vertical demolding plane (P) such that an undercut value of the pot with respective side ends of the pot, with a maximum side spacing of the outside surface in relation to the vertical demolding plane (P), is less than a maximum undercut value of the pot on the circumference of the outside surface of the pot.

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.
