A kind of manufacturing process of hat metal sign

Abstract

The invention relates to a making process of a metal tag and discloses a making process of a cap metal tag. The making process comprises a blanking process, a punching process, a resistance coating pre-coating process, a pattern outline trajectory numerical control carving process, a first electroplating process, a resistance coating removing process, a bending process, a second electroplating process, a paint coloring process and a drying process; in the paint coloring process, the back surface of the metal tag is absorbed on a magnetic positioning frame, the front surface of the metal tag faces upwards, and an internal area formed by a pattern outline trajectory is dispensed with a layer of nano-sized iron powder paint or a layer of micron-sized iron powder paint; the nano-sized iron powder paint is formed by adding nano-sized iron powder in paint; the micron-sized iron powder paint is formed by adding micron-sized iron powder in paint. The making process provided by the invention solves the problem that the paint is easy to hang on an edge when the arc-shaped metal tag is dispensed.

Description

technical field [0001] The invention relates to a production process of a metal label, in particular to a production process of a hat metal label. Background technique [0002] A typical hat metal sign is made of metal plate and bent into an arc suitable for the hat, with a pattern (including text as the content of the pattern) on the front. In order to improve the aesthetics of the metal signage, a raised golden edge is provided on the contour edge of the pattern (pattern contour trajectory line), and the internal area surrounded by the contour edge of the pattern can be painted to make each area get different colors of paint coating. [0003] In the existing production process of hat metal signage, since the metal signboard has a curved shape, the surface of the painted area is inclined relative to the horizontal plane, which may easily cause the paint to flow along the inclined surface and hang on the golden edge after spot painting, and the serious hanging edge may even...

AI Technical Summary

Problems solved by technology

[0003] In the existing production process of hat metal signage, because the metal signboard has a curved shape, the surface of the painted area is inclined relative to the horizontal plane, which is easy to cause the paint to flow along the inclined surface and hang on the golden edge after spot painting, and the serious hanging edge may even cause Different color paint areas cross colors, not only need secondary treatment, scrape off or repaint the paint hanging on the golden edge, which is not only time-consuming and labor-intensive, but also leads to the deterioration of the appearance quality of the metal signage after secondary treatment

[0004] In order to solve the above problems, the viscosity of the paint can be adjusted to prevent the paint from hanging, but the increase of the viscosity of the paint will reduce the fluidity of the paint, which will easily lead to the unevenness of the coating in the painting area and affect the appearance. The lack of coating is easy to occur at the corners, and it is necessary to manually repaint the missing parts, which is also time-consuming and labor-intensive and affects the appearance quality
