The present disclosure includes dental appliances and methods of making and using such appliances. One method for forming a dental appliance includes forming a liquid thermoset polymer material into a semi-solid first shape, thermoforming the semi-solid first shape of thermoset polymer material onto a dentition mold, and curing the thermoset polymer on the dentition mold with a curative trigger to complete a molecular cross-linking reaction.

Methods of forming a dental appliance. The methods may include partially curing a prepolymer mixture into a semi-solid polymer material having a first shape that is a sheet. The semi-solid polymer material may be placed over a dentition mold, wherein the semi-solid polymer material may take on a second shape corresponding to a shell having one or more cavities for receiving one or more teeth. The semi-solid polymer material may be fully cured by exposure to energy until the semi-solid polymer material thermosets in the second shape.

A method of forming a decorative article comprising placing a decorative cover sheet comprising an untextured skin layer, a cushion foam layer and an adhesive layer in a mold space between a front mold half and a rear mold half, placing a substrate on the rear mold half, heating a textured front mold surface and the skin layer with a first heater arrangement between the front mold half and the cover sheet, heating the cover sheet and the substrate with a second heater arrangement between the cover sheet and the rear mold half, forming the skin layer of the decorative cover sheet into contact with the textured front mold surface, forming into the skin layer a textured surface from the textured front mold surface, pressing the substrate against the adhesive layer of the decorative cover sheet, and bonding the cover sheet to the substrate with the adhesive layer.

A method for continuously fabricating a composite sandwich structure includes the steps of: (1) moving a laminate, substantially continuously, through a preheating zone, wherein the laminate includes a first face sheet, a second face sheet and a core sandwiched between the first face sheet and the second face sheet; (2) preheating the laminate to a preforming temperature above a glass transition temperature of the laminate and below or equal to a crystalline melt temperature of the laminate as the laminate is being moved through the preheating zone; (3) moving the laminate, substantially continuously, through a consolidation zone; and (4) consolidating the laminate as the laminate is being moved through the consolidation zone to form a continuous length of the composite sandwich structure.

A method for producing a multi-component part (200) of a vehicle includes inserting an air-guiding device (10) having at least one contact portion (40) into a cavity (310) of a tool (300). The method then includes heating a composite part (100) having at least one mating contact portion (140) to a melting point of at least one material of the composite part (100), and heating the contact portion (40) of the air-guiding device (10) to a melting point of at least one material of the contact portion (40). The method further includes inserting the heated composite part (100) into the cavity (310) of the tool (300) and pressing the heated composite part (100) into a geometry of the part while simultaneously forming an integrally bonded connection between the mating contact portion (140) of the composite part (100) and the contact portion (40) of the air-guiding device (10).

A composite product comprising a fibrous material (A) and a polymer material (B), wherein the composite product is formed as a sheet, by wet web formation and wherein said web is formed from a suspension of said fibrous material and said polymer material in a double wire press (2a and 2b).

A method for producing a fiber-reinforced resin molded body, including heating a fiber-reinforced resin molded body precursor containing thermoplastic resin as matrix resin to soften it and molding it in a molding die, where temperature unevenness between the inside and surface of the fiber-reinforced resin molded body precursor can be reduced. The method includes a first step of storing a fiber-reinforced resin molded body precursor containing thermoplastic resin as the matrix resin and containing conductive fibrous materials therein into a heating furnace with heating apparatuses while holding the precursor using a pair of holding tools, which also function as electrodes, and then actuating the heating apparatuses while supplying current to the precursor from the electrodes, thereby softening the precursor; and a second step of transferring the softened precursor to a molding die using the holding tools, and molding a fiber-reinforced resin molded body in the molding die.

A conveyance device includes a plurality of holding mechanisms and one or more pressing mechanisms, the holding mechanisms each include a holder that holds a molding material and a holder movement mechanism that moves the holder, and the pressing mechanisms each include a pusher that comes into contact with and pushes the molding material and a pusher movement mechanism that moves the pusher.

A forming device has a machine frame and a forming apparatus disposed on the machine frame. At least one heating chamber is disposed on the machine frame. A heatable support is received in the at least one heating chamber in a position of use for preheating semi-finished products and can be moved in a movement direction out of the at least one heating chamber into a removal position for removal of preheated semi-finished products from the support. In the removal position, the support is at least partially located adjacent to the machine frame and enables access to preheated semi-finished products. At least one heating device is associated with the at least one heating chamber and has one or more convection heating devices that discharge at least one directable heating air flow.

A heating apparatus is provided, and includes a blank and a heating pad in contact with one side of the blank. The heating pad has, or is formed from, a first base matrix. A first region of conductive particles is dispersed within the first base matrix, and a second region of conductive particles is dispersed within the first base matrix. An induction heater is configured to inductively heat the conductive particles within the heating pad. The first region of conductive particles is heated to a first temperature and the second region of conductive particles is heated to a second temperature, which is greater than the first temperature.
