[0002] Door gap cover plates can be used on a variety of doors such as fire doors and anti-theft doors. Fire door gap cover plates are specially set in the middle gap of double-opening fire doors. They are long fireproof plates with the same width and height as the door leaf. Their function is to strengthen the sealing performance of the door gap to prevent smoke from spreading and flames from penetrating through the gap. In order to improve the sealing effect and safety performance of anti-theft doors, it is necessary to install door gap cover plates on the door lock side of the anti-theft door or on the middle gap between double-opening anti-theft doors. The conventional molding process of door gap cover plates is generally divided into two processes: beveling and flanging.
