Manufacturing process of stainless steel door

Abstract

The invention discloses a manufacturing process of a stainless steel door. The manufacturing process comprises the following steps that first, a door frame and a door leaf are manufactured, wherein the manufacturing process comprises the following steps of molding the door frame and conducting cutting, bending, punch forming and welding on a door leaf plate; second, the surface is washed, wherein the washing process comprises the following steps that at first, the door frame and the door leaf are soaked in a degreasant water solution for 2-30 min, and are then soaked in clear water for 1-10 min; third, the surface of the door leaf and the surface of the door frame are coarsened; fourth, primer is sprayed, wherein the spraying process comprises the following steps that at first, the door frame and the door leaf are placed in an oven to be heated to 50-200 DEG C, and then the primer begins to be sprayed; fifth, finish is sprayed, wherein the spraying process comprises the following steps that the door frame and the door leaf are placed on a spraying frame to be coated with the finish, the door frame and the door leaf, coated with the finish, are placed in the oven to be heated for 50-200 DEG C, and then the heated door frame and the heated door leaf are dried; and six, packing and warehousing are performed. Before spraying, the door leaf and the door frame are soaked in the degreasant water solution and coarsened, so that the adhesive force of the primer and the finish sprayed on the bottom surfaces and the surfaces of the door leaf and the door frame is improved, the door frame and the door leaf are not prone to be corroded by the outside, the falling of a spraying layer is avoided, and the water resistance of the spraying layer is improved.

Description

technical field [0001] The present invention relates to the technical field of stainless steel doors, and more specifically, relates to a manufacturing process of stainless steel doors. Background technique [0002] Stainless steel doors are generally used as gates. However, cost-effective stainless steel doors require a better manufacturing process. Regarding the production process of stainless steel doors, the disadvantages of the existing technology are that the stainless steel doors after processing are susceptible to external corrosion, Cause the surface spray coating to fall off, and the waterproof performance is poor. For this reason, it is necessary to design an improved manufacturing process for stainless steel doors. Contents of the invention [0003] The object of the present invention is to provide a manufacturing process of a stainless steel door which is not easily corroded and has high waterproof performance. [0004] In order to achieve the above object, ...
