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.

A method for thermoforming synthetic paper is provided, more concretely for thermoforming holding strips of synthetic paper, the strips being used to produce sheet-holding devices of a specific configuration. The devices can be used in the assembly of sheet holders such as calendars, white sheet dispensers or information cards.

Method for shaping a film/sheet, particularly for making three-dimensional shapes in it, in which case the outlines of the shape to be formed are warmed/heated and the film/sheet is stretched along the heated outline, in order to cause the part of the film/sheet inside it to deviate from the plane of the surface. The heated outlines are created by, for example, directing a moving beam of thermal radiation onto it. A countersurface is provided to limit the stretching and ensure that rupture does not occur. By repeating the procedure sequentially, a great variety of shapes may be created.

[Problem] To suppress changes in the recess depth and shape of a three-dimensional molded shape, and to form a uniform protective layer or ornamental layer along the surface of the molded shape. Also, to provide uniform application to the entire irregularly-formed surface and to suppress air pockets and partial defects of bonding. [Solution] In an adherend W having a three-dimensional molded portion in which a plurality of concavities and/or convexities are molded in a regular arrangement, a thermoplastic coating film larger than the area of an adhesion region is integrally adhered by a three dimensional decorative molding procedure in a predetermined adhesion region that includes the three-dimensional molded portion. The predetermined adhesion region includes all of the three-dimensional molded portion and covers more than half the perimeter of the adherend W incenter cross-sectional view.

A dental appliance manufacturing system includes a plate. Molds of dental arches are to be positioned on the plate. The dental appliance manufacturing system further includes a heating section configured to be adjusted based on the molds positioned on the plate. The heating section is configured to heat one or more sheets of plastic to generate one or more heated sheets. The dental appliance manufacturing system further includes a thermoforming chamber configured to simultaneously thermoform the one or more heated sheets over the molds positioned on the plate to form a plurality of dental appliances.

Some embodiments of the present disclosure include a mandrel system for creating a stamp on multiple receptacles. Some embodiments of the method include performing a step in the stamping process on a single receptacle while simultaneously performing another step in the stamping process on a second receptacle. The mandrel system may include a rotating mandrel system for rotating the mandrels that hold the receptacles to various positions, where the positions may be aligned with certain steps, such as heating, stamping, or cooling a portion of the receptacle. Some embodiments include a reversible lid including a fastening mechanism to fasten the lid in at least two configurations. In some embodiments, one side of the lid can be used to stack receptacles and the other side of the lid can be used to hold objects in slots and be used as a seat.

Methods for manufacturing thermoformed objects are provided. In some embodiments, a method includes controlling a material transport system to move a material to a first location proximate to one or more heat sources. The method can include controlling the one or more heat sources to heat a first region of the material to a first temperature and heat a second region of the material to a second temperature. The method can also include controlling the material transport system to move the material to a second location proximate to an object forming element, and controlling the object forming element to form a dental appliance from the material.

A method of forming a blow moulded container in the form of a tub, the method comprising the steps of: providing an injection moulded preform composed of a biaxially-orientable thermoplastic material, the preform being substantially planar; heating the preform; and stretch blow moulding the heated preform within a mould cavity to form a tub having a bottom wall and an annular sidewall having an upper edge, the tub comprising biaxially oriented thermoplastic material in the annular sidewall and at least an outer portion of the bottom wall, the stretch blow moulding step using at least one stretch rod to engage an inner side of the preform and axially to stretch at least a part of the preform prior to blowing a pressurized gas against the inner side which urges the opposite side of the preform radially outwardly against the mould.

A method includes identifying one or more images of a mold of a dental arch, identifying a digital model corresponding to the mold of the dental arch, providing the one or more images and the digital model as input into a trained machine learning model, receiving, from the trained machine learning model, output, and determining, based on the output, whether the mold matches the digital model.

An orthodontic appliance made by a thermal forming process is provided. The thermal forming process can include heating a thermoformable material using a plurality of independently controllable heat sources. The plurality of independently controllable heat sources can produce at least one overlapping heating zone. The thermal forming process can further include monitoring one or more temperatures from a plurality of temperature sensing elements operably coupled to different areas of the thermoformable material. The thermal forming process can further include adjusting power of one or more of the plurality of independently controllable heat sources based on the one or more monitored temperatures such that each of the different areas of the thermoformable material reaches a respective desired temperature. The thermal forming process can further include disposing the heated thermoformable material over at least a portion of a mold to form the orthodontic appliance.
