Abstract: Provided is a method for manufacturing a metal card which is capable of allowing metal card antennas to have no interference with a metal sheet by including a processed plastic layer formed on the metal sheet, and an insulating sheet. The metal card is capable of improving sensitivity of antenna coil, thereby solving an existing problem of the difficulties in performing RF communication because of material characteristics of a metal layer.

Abstract: A sub-frame mounting structure is provided. The sub-frame mounting structure includes an outer pipe that is mounted on a vehicle body and an inner pipe that is inserted into and coupled to the outer pipe and detached from the outer pipe when an impact load of a predetermined size or greater is transferred thereto. An anti-rotation structure prevents a relative rotation between the inner pipe and the outer pipe. A sub-frame is fastened to the inner pipe to support the vehicle body through the outer pipe to stably support the vehicle body by the sub-frame and to detach the sub-frame from the vehicle body during a collision.

Abstract: Disclosed is a bulletproof panel that can replace glass of a vehicle, an elevator, a meeting room, a ticket booth, or the like. The bulletproof panel includes a base layer, a reinforcing layer provided on each of opposite sides of the base layer, and an adhesive layer provided on the base layer and each of the reinforcing layers and made of a UV-curable urethane resin. The bulletproof panel is characterized in that when the panel is impacted by a bullet, the base layer breaks and absorbs a rotational force of the bullet, while the reinforcing layers provided on respective opposite sides of the base layer suppress broken pieces of the base layer from scattering. Thus, the bulletproof panel can exhibit an excellent bulletproof effect because the bullet is fixed in the base layer and does not penetrate therethrough, while preventing broken pieces generated by the bullet from scattering.

Abstract: A mounting unit is provided that improves compatibility to be applied to various parts of a vehicle body which is coupled with a chassis by manufacturing the mounting unit to include a bracket and hardware. The mounting unit includes a bracket that has a first panel and a second panel, which are respectively bent several times, are combined with each other to form an empty portion to be surrounded by the first panel and the second panel and fixed to a vehicle body. Additionally, the mounting unit includes a hardware that is disposed in the empty portion to be fixed by being combined with the first panel and the second panel and adapted to form a thread for engaging a fastening mechanism.
