CONFORMABLE SHIELDING FILM
A method of thermoforming a rigid film construction. The method comprises: applying a rigid film construction to a mold; and heating the rigid film construction until it conforms to the mold. The rigid film construction includes a rigid polymeric film layer; a light-modifying film layer; and a shielding film layer. The shielding film comprises polymethyl methacrylate (PMMA); and the shielding film layer contacts the surface of the mold.

Apparatus and methods for selective thermoforming
Apparatus and methods of forming selected portions of integral sheets of material are disclosed. Unformed portions of the sheets may remain undistorted during the forming process, allowing them to contain text, art work, or other desired information without material risk of the information being degraded or becoming unintelligible during the forming process. This result may be accomplished, moreover, with less trim than usually occurs in conventional forming processes.

Method of manufacturing cross-corrugated support structures
A method of manufacturing cross-corrugated support structures is provided. A mold having a molding surface with a first plurality and a second plurality of corrugations therein is used to introduce corrugations into a flexible, carbonaceous sheet. Cross-corrugations are introduced into the sheet by placing the sheet onto the molding surface, encapsulating the sheet to form a vacuum chamber, and evacuating the vacuum chamber of air. As air is evacuated from the vacuum chamber, the sheet is drawn upon the molding surface causing the sheet to conform to the shape of the molding surface. Thermosetting resin is infused into the sheet and cured causing the sheet to rigidly retain the shape of the molding surface. The sheet is further reinforced by securing at least one support member to the sheet using thermosetting resin.
Vacuum plastic molding machine
A vacuum plastic molding machine includes a heating device, a plurality of upright posts, a carrier assembly, and a demolding mechanism. The carrier assembly includes an upper carrier and a lower carrier. The upper carrier includes an upper frame, multiple upper movement structures, at least one rotation plate, at least one driving member, and at least one linking mechanism. An adjusting space is defined between the at least one rotation plate and the at least one linking mechanism. The lower carrier includes a lower frame, multiple lower movement structures, and at least one locking tenon. The locking tenon is placed into the adjusting space. The at least one driving member is rotated to change the position of the at least one locking tenon in the adjusting space, and to adjust the distance between the upper carrier and the lower carrier.

UV-CURABLE RESIN COMPOSITION FOR VACUUM FORMING AND REPLICA FILM OF REAL MATERIAL COMPRISING THE SAME
Disclosed are a UV-curable resin composition for vacuum forming and a replica film of a real material including the same. The UV-curable resin composition includes a prepolymer including a urethane-containing oligomer, an acrylate monomer and a photoinitiator.
Blow molding device capable of continuous processing
The present invention relates to a blow molding device including: a heating unit which is configured to heat a molding material; and molds between which the molding material is loaded and molded, in which the heating unit includes: an infrared lamp configured to emit infrared rays, a reflective mirror configured to concentrate the infrared rays emitted from the infrared lamp; and a light transmitting body configured to transmit the infrared rays concentrated by the reflective mirror to the molding material, and in which the molds mold the molding material by using gas pressures applied to surfaces of the molding material heated to a predetermined temperature by the infrared rays transmitted from the light transmitting body.
PRODUCTION PROCESS OF A COMPOSITE PRODUCT
Production process of a composite product (1) comprising a core (2), a first layer (3) comprising a sheet impregnated with a solid polyurethane material, and a polymer-based film (7) applied to the first layer (3), wherein the process comprises: producing a semi-finished product comprising the core (2) and the sheet impregnated by a liquid mixture precursor of the solid polyurethane material; adhering the film (7) to a first half-mould (11) by applying a depression between the film (7) and the half-mould (11); pressing two half-moulds (11, 12) against each other with the semi-finished product interposed between two shaping surfaces (13), so that the film (7) comes into contact with the liquid mixture; with the semi-finished product in the mould, thermosetting the liquid mixture to transform it into the polyurethane solid material so that the film (7) firmly adheres to the first layer (3) and thus producing the composite product (1).
