Method for manufacturing automobile casing with design on surface

Abstract

The invention discloses a manufacturing method of a vehicle shell the surface of which is provided with a pattern; the vehicle shell is manufactured by a metal material; the section structure of the vehicle shell is provided with a metal layer; the upper surface on the metal layer is a putty layer; the upper surface of the putty layer is a primer layer; the upper surface of the primer layer is a dye layer for manufacturing the pattern; the upper surface of the pattern layer is a varnish layer; the upper surface of the varnish layer is a glossy paint layer. The manufacturing method includes the following steps of: manufacturing the metal shell according to the shape of the vehicle shell; then uniformly placing and troweling the putty on the metal surface; drawing the pattern on the dye layer; carrying out satinizing and spraying the varnish after the pattern is dry; carrying out satinizing after the varnish is dry and finally covering the glossy paint layer. The manufacturing method has the advantages that: the needed pattern or characters are directly drawn on the primer by adopting the dye, pattern or character grain is clear, shape forming is good and transparency is high as well as no special requirements is needed on the pattern manufacturing technique, thereby manufacturing cost is low and the actual operation is convenient.

Description

technical field [0001] The invention relates to a car shell, in particular to a method for making a car shell with patterns on its surface. Background technique [0002] As a means of transportation, automobiles have entered common people's families. With the substantial increase in the use of automobiles, patterns or characters have been made on the surface of automobiles in this field to achieve the promotion of products or the decorative effect on the surface of automobile shells. At present, the methods of making patterns or characters on the car body are generally divided into the following categories: ① Directly make the pattern or characters on the outermost layer of the paint. The disadvantage of this method is that it affects the brightness of the car surface, and the pattern or characters The text is easy to fade or fade; ②In the process before the car is painted, the decorative pattern or text is made on the rice paper, and then the rice paper is attached to the c...

Problems solved by technology

At present, the methods of making patterns or characters on the car body are generally divided into the following categories: ① Directly make the pattern or characters on the outermost layer of the paint. The disadvantage of this method is that it affects the brightness of the car surface, and the pattern or characters The text is easy to fade or fade; ②In the process before the car is painted, the decorative pattern or text is made on the rice paper, and then the rice paper is attached to the car primer. The disadvantage of this method is that the production process is particularly strict. The manufacturing cost is greatly increased, and it is easy to cause the varnish on the surface of the car to fall off; ③ It has been reported in the published literature that the pattern is sprayed on the surface of the car before the paint is baked. After research, it is found that this method cannot be implemented

Because the above methods all have many deficiencies, they cannot be popularized and applied so far.
