Polyurethane logo label manufacturing method and polyurethane logo label attachment method
The present disclosure relates to a polyurethane logo label manufacturing method that includes: a first step of preparing a polyurethane image film printed with a logo; a second step of preparing a wing film laminated by combining a polyurethane film and a PET film; a third step of forming an injection hole for injection into a logo groove of the wing film; a fourth step of film molding option of preparing a mold composed of a top plate, a mid-plate, and a bottom plate; and a fifth step of injection molding of injecting polyurethane resin into the logo groove through the injection inlet of the top plate of the fourth step.
1 . A polyurethane logo label manufacturing method comprising:
a first step of preparing a polyurethane image film printed with a logo;
a second step of preparing a wing film laminated by combining a polyurethane film and a PET film;
a third step of forming an injection hole for injection into a logo groove of the wing film;
a fourth step of film molding option of preparing a mold composed of a top plate, a mid-plate, and a bottom plate, that is, of preparing a bottom plate on which a logo groove having the same shape as a logo and having depth by a thickness of the logo is formed and a seat groove having the same shape as the wing film and having a depth by a thickness of the wing film is formed, of preparing a mid-plate closing the logo groove and the seat groove by being assembled to overlap the bottom plate, having a path groove, through which polyurethane resin can flow, on a top thereof, and having an injection hole formed at the path groove to be connected with the injection hole of the wing film, of preparing a top plate closing the path groove by being assembled to overlap the mid-plate and having an injection inlet, through which polyurethane resin can be injected, on a top thereof, and then of inserting the image film onto a bottom of the logo groove of the bottom plate, and of inserting the wing film into the seat groove, thereby mounting the wing film into the mold; and
a fifth step of injection molding of injecting polyurethane resin into the logo groove through the injection inlet of the top plate of the fourth step such that the portion between the image film and the wing film is filled with the polyurethane resin, a logo of the image film is transcribed and thermally bonded to a front of the polyurethane resin by heat of the polyurethane resin, a polyurethane film of the wing film is partially melted by heat of the polyurethane resin and integrally thermally bonded to a bottom of the polyurethane resin, and then of separating the mold.
