摘要

PURPOSE: A half and through-etching manufacturing method of a door scuff and the half of a door step is provided to make a small gap less than 1mm by forming through-pattern through an etching process.;CONSTITUTION: A half and through-etching manufacturing method of a door scuff and the half of a door step comprises the following steps. The foreign material of a prepared plate(50) is removed(S1,S2). The films(70,80) having a through-pattern(75) is attached to a dry film(60) attached to the surface and rear side of the plate(S3,S4). The ultraviolet ray is firstly exposed to the plate(S5). A part of the plate where the dry film is removed is firstly corroded to the etching solution. The hardened dry film of the plate is removed. The film having an embossment pattern and an intaglio pattern is attached to the surface and rear side of the plate. The ultraviolet ray is secondly exposed to the plate. A part of the plate in which the dry film is removed is corroded. In order that the firstly corroded part is penetrated, it is corroded. The rim of the door side and door step is punched to the mold and is separated from the plate.;COPYRIGHT KIPO 2012
