Chromatic car spraying method

Abstract

The invention provides a chromatic car spraying method. The method comprises the following steps of: (a) manufacturing a formwork, wherein the edge of the formwork coincides with a boundary of colors to be sprayed; (b) locating the formwork on a car body and aligning the edge with the boundary of the colors to be sprayed; (c) marking the junction of the edge of the formwork and the car body; (d) taking down the formwork, determining a spraying boundary according to the mark and sticking masking paper to the car body parts which do not need to be sprayed; and (e) spraying the colors to be sprayed on the car body. The method has the following beneficial effects that: not only is the manufacturing cost of the formwork saved, but also the formwork can be reused, thus greatly saving the cost; the method is not only simple but also easy to operate; plenty of working hours are saved; the pattern uniformity among the same type of cars is improved; and the chromatic spraying quality can be improved by adopting the method compared with the existing methods.

Description

technical field [0001] The invention relates to a method for spraying an automobile, in particular to a method for over-coloring and spraying an automobile. Background technique [0002] Chromatic spraying means that the car body has different colors, and each color needs to be sprayed in stages. Usually, when spraying the special pattern of the car, especially when there are arcs on the edges of different colors, it is necessary to engrave at least part of the pattern that needs to be masked with a back-adhesive material to make a template. For each part of the car body Both sides need to be over-colored and sprayed, and it is more beneficial to use multiple templates for the parts that need to be covered, then it is necessary to make multiple templates to cover the corresponding parts on the body during the spraying process. [0003] In actual operation, the first color is sprayed on the whole vehicle; after the paint of the first color is dried, the worker pastes the abo...

Problems solved by technology

[0004] The above method has the following disadvantages: First, the template is not easy to fix. Although the template has adhesive backing, it is not easy to control when pasting a large area. The deformation of the pattern will also cause errors between the patterns of different vehicles of the same model; secondly, a set of templates can only be used for the spraying of one car, and a transfer film is required, and the price of each set of templates does not include the design fee. It needs 300-400 yuan, and the production cost is expensive; moreover, this kind of template cannot tightly wrap all the parts that need to be covered, and needs to be covered with masking paper; in addition, although the masking paper can withstand high temperature, the template cannot be baked at high temperature , so the template must be removed after spraying to send the car body to the drying oven for paint, and it is easy to damage the wet paint film when the template is torn off; in addition, there must be errors in the template engraving, and the patterns of each set of templates Inconsistency will cause inconsistency in the pattern of the body
