Title:
3D FORMING FILM MANUFACTURING APPARATUS HAVING FORMING FILM IDENTIFICATION FUNCTION, AND 3D FORMING FILM MANUFACTURING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/263021
Kind Code:
A1
Abstract:
One embodiment of the present invention provides a 3D forming film manufacturing apparatus and method wherein: shaping of a forming film is performed at uniform pressure by using a volume-variable body and thus it is possible to shape undercut portions; the deviation in thickness of a forming film is reduced and thus the quality of a 3D-shaped forming film is improved; and when a non-certified forming film or die is used, the non-certified forming film or die can be identified. The 3D forming film manufacturing apparatus having a forming film identification function according to an embodiment of the present invention comprises: a die for shaping a forming film; a press head unit arranged to correspond to the die and spaced a variable distance apart from the die; a volume-variable body coupled to the press head unit, having elasticity such that the volume thereof can be changed according to fluid flow into or out of the body by the press head unit, and changing the volume thereof so as to come into contact with a forming film placed in the die and press the forming film, thereby shaping the forming film into a 3D shape; and an ultrasonic analysis unit delivering ultrasound through the forming film so as to analyze the forming film.
