Abstract

본 발명은 얇은 중앙부(2)와 두꺼운 테두리(3)부로 이루어진 자기용 창(1)의 사출성형시 상기 창(1)성형용 원재료에 보라색 안료를 첨가한 후 사출하여 상기 중앙부(2)와 테두리부(3)를 각각 반투명성과 불투명성으로 형성한 도어폰의 자기용 창(1)으로서 적외선의 파상투과 방지와 더불어 제작공정의 단순화를 꾀할 수 있는 특징이 있다.In the present invention, when the injection molding of the magnetic window (1) consisting of a thin central portion (2) and a thick edge (3), the addition of a purple pigment to the raw material for forming the window (1), and then injected into the central portion (2) and the edge As the magnetic window 1 of the door phone in which the sections 3 are formed translucent and opaque, respectively, there is a feature that can simplify the manufacturing process as well as preventing the infrared light from passing through.
