A method and system for thermal forming an object. A mold is provided, a shape of which corresponds to a desired shape of the object. A material is inserted into a heating area, and the material is heated using a plurality of independently controllable heat sources that heat different areas of the material. The heated material is then disposed over or into at least a portion of the mold so as to deform the material. The deformed material may then be trimmed so as to form the object.

A method for shaping a preform made from thermoplastic material, and a facility for implementing the method, comprising the following steps: a) providing a preform made from thermoplastic material having a surface; b) supplying thermal energy to the preform by radiation in such a way as to make it ductile; and c) shaping the ductile preform inside a forming mould. Step b) further involves simultaneously spraying a gaseous fluid onto the surface of the preform in order to preserve the surface.

An assembly for manufacturing containers by thermoforming, which includes a magazine of thermoplastic sheet-like blanks, a feeding station for feeding the blanks, a heating station for heating the blanks, and a station for thermoforming containers starting from the blanks. The feeding station includes a closed-loop path and at least two conveyor elements, which move, following each other, along the path between a loading position, in which the conveyor element faces the blank magazine, and an unloading position, in which the conveyor element faces the heating station. The heating station includes a heating carousel, wherein, in the active condition, the conveyor element in the unloading position moves with a substantially linear motion with a speed that is substantially equal to a peripheral speed of the heating carousel.

The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered to the inner surface of the body ply and has a portion extending across the aperture, forming a window into the container. The method involves providing a window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device that is adapted to release pressurized air into the container through at least one of the platens. The container is engaged between the platens in an airtight manner and, optionally, the container window is positioned adjacent the inside wall of the machine pocket. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.

A method of forming an automatic dishwashing pouch comprising the steps of: providing a sheet of material (10); identifying one or more regions of the material; heating the material with a heating device having a non-uniform heating profile, the non-uniform heating profile arranged to heat the identified region(s) to a greater temperature than other regions of the material; and forming the material in a mould to form the automatic dishwashing pouch, the automatic dishwashing pouch including a plurality of cavities (12).

[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 warpage reduction device the present disclosure includes a jig having a warped shape capable of distributing stress of a workpiece, a light source heating the workpiece so as to be flat, a pressurizer applying pressure to the heated workpiece to be pressed against the jig so as to be deformed, a cooler cooling the deformed workpiece, and a controller controlling operations of the light source, the pressurizer, and the cooler.

A system is configured to manufacture an aligner. The system includes a heating section configured to heat a sheet of plastic to generate a heated sheet of plastic. The system further includes a plate configured to secure a mold associated with a dental arch of a patient. The plate includes a keyway and a pin. The mold includes a first feature configured to interface with the keyway and a second feature configured to interface with the pin. The system further includes a thermoforming chamber configured to thermoform the heated sheet of plastic to the mold that is secured to the plate via a first interface of the keyway with the first feature and a second interface of the pin with the second feature to generate a thermoformed sheet of plastic. The system further includes a cutting tool configured to trim the aligner from the thermoformed sheet of plastic.

A method for blow molding a container includes heating a central region of a preformed puck to a first temperature, and heating an annular region surrounding the central region of the preformed puck to a second temperature that is greater than the first temperature. The heated preformed puck is arranged at an upper end of a mold cavity of a mold that defines an outer shape of the container. The heated preformed puck is secured to the upper end of the mold cavity. The heated reformed puck is stretched by pressing a plunger into the heated preformed puck and into the mold cavity in a longitudinal direction of the mold cavity toward a lower end of the mold cavity. Pressurized air is then applied to the mold cavity so that the heated preformed puck stretches to conform to the shape of the inner wall of the mold cavity.

A heating module for heating at least one film element. The heating module has two or more heating segments with in each case one or more heating elements for heating a first area of the film element assigned to the respective heating segment, wherein the heating module and/or at least one of the heating segments includes at least one sensor for measuring the state of the heating of the film element.
