Description

  The present invention relates to a method for manufacturing a door with a molding material and the door.

Patent Document 1 describes a so-called flash door in which a heat insulating material is sandwiched between two steel plates, and a molding material is attached so as to be recessed from the door surface. In this door, the concave portion for embedding the molding material in the steel plate must be processed by pressing or the like, which is costly and troublesome. If there is an error in the shape of the recess, the molding material will rise or fall off the door surface.
Therefore, instead of processing the recess in the steel plate, it can be considered that the steel plate is separated into the inner side and the outer side of the molding material in advance, and then the blank dimension between the inner steel plate and the surrounding steel plate is extended over the entire circumference. It is not easy to ensure a certain level, and it may be difficult to mount the molding material, or may be detached after mounting, which makes the production troublesome.
