A method including inserting into a mold a first tool having a first surface. The method further includes printing a second tool from a polymer material and inserting the second tool into the first tool. The second tool having a smaller wall thickness than the first tool and including a second surface opposing and in contact with the first surface of the first tool and a third surface formed on an opposite side of the second tool than the second surface.

A thermoforming device (1) is provided for performing a heating process of radiationally heating a resin film (4) to a predetermined temperature (C21) by a radiation heater (6) and a bonding process of bonding the radiationally heated resin film (4) to a pulp mold (10) set on a base (52). The thermoforming device (1) is provided with a vacuum pump (7) to evacuate a space between the pulp mold (10) and the resin film (4) to bring the resin film (4) to be in close contact with the pulp mold (10) in the bonding process. The radiation heater (6) is changeable in its distance to the resin film (4) between a first heating position to perform radiation heating of the resin film (4) in the heating process and a second heating position to perform radiation heating of the resin film (4) in the bonding process.

An apparatus for skin application of a thermoformable film (9) to a support (3), comprising a supporting element (4), defining a working chamber (6) for receiving a support (3), and a closing element (5), which has a lower heating face (8). The supporting element (4) and the closing element (5) are movable between a home position, in which the working chamber (6) is open, and a working position, in which the upper opening (7) is completely closed by the lower heating face (8). The supporting element (4) comprises a housing portion (15), defining a housing (19) for the support (3), a distancing portion (16), between the housing portion (15) and the upper opening (7) and defining a distancing space (21) interposed between the housing (19) and the upper opening (7), and cutting means (23) which surround the housing (19).

A method of forming a vacuum insulated structure includes providing a structural envelope an insulating cavity defined within the structural envelope. An expanding device is attached to opposing outer walls of the structural envelope and the interior cavity is expanded by pulling the opposing outer walls away from one another to define an expanded state. An insulating material is disposed within the insulating cavity to occupy substantially all of the insulating cavity in the expanded state. Gas is expressed from the insulating cavity to collapse the structural envelope to a final state and a final interior volume that is less than the expanded interior volume. The final state of the structural envelope defines a densified state of the insulating material within the insulating cavity. The vacuum port is then closed to hermetically seal the insulating cavity.
