Manufacturing method of metal product with decoration veins and finished product thereof

Abstract

The invention discloses a manufacturing method of a metal product with decoration veins and a finished product thereof. The metal product comprises a metal substrate and decoration veins formed on the outer surface of the metal substrate in brushing manner, wherein the metal substrate is provided with an outer surface. The manufacturing method of a metal product comprises the following steps: preparing the metal substrate provided with an outer surface; preparing a shadow mask provided with two or more hollowed-out grooves; attaching the shadow mask at the outer surface of the metal substrate, and forming an area to be processed at the outer surface of the metal substrate corresponding to the hollowed-out grooves; brushing the area to be processed with a metal brush and forming the decoration veins at the outer surface of the metal substrate; providing a pressure forming mold; and arranging the metal substrate in the pressure forming mold and applying pressure for pressure forming. Moreover, the invention further provides a metal substrate manufactured by using the manufacturing method to ensure that the metal substrate has metallic luster and increases the visual effects such as identification performance and aesthetic property.

Description

technical field [0001] The invention relates to a metal product and its manufacturing method, especially to a metal product with ornamentation and its manufacturing method. Background technique [0002] With the advancement and development of science and technology, the demand of consumers for electronic products such as mobile phones and notebook computers is becoming more and more personalized and refined. The appearance of these electronic products often affects consumption. One of the main reasons why buyers are willing to buy. In addition, in the past, most of the manufacturing methods used to treat the surface of the metal shell of these electronic products are to first pickle or sandblast the surface of the metal plate and then apply molding. However, this manufacturing method will Stretch lines are formed on the surface of the metal sheet or the lines are diluted and blurred, both of which will affect the aesthetics of the surface of the metal sheet. [0003] The k...

[0005] However, the aforementioned casing and its manufacturing method can beautify the surface of the casing. Among them, the publication number 505842 has a rather cumbersome and complicated manufacturing process, which not only requires special tools for processing, but also produces The cost of the shell is also high, and it is not suitable for products that are increasingly low-profit

In addition, the magnesium-aluminum alloy plate produced by the announcement number 555888 does not have the aesthetic feeling of metallic luster
