Detailed explanation of the etching process of machined aluminum alloy parts with surface texture close to the appearance of Apple mobile phones

Parts with high surface texture requirements include: audio panel, nameplate LOG, watch case, etc. However, most of the etching processes used in the industry are on the surfaces of stainless steel, copper, and titanium alloys, but few people try on the surfaces of aluminum alloys, because the chemicals in the etching process themselves are a great harm to the parts. .

VMT CNC processing manufacturers not only challenge the etching process of aluminum alloy materials, but also challenge the aluminum alloy etching parts of three-color oxidation, which is a very difficult job. At the same time, it is also a very meaningful work, because it can meet the needs of many personalized parts, and has accumulated rich experience for us. The following are several ways of exploring, which can provide guidance for you in the same industry.

1. Distinction of processing experience

From the processing experience, the etching factory distinguishes parts that are professionally made of stainless steel and professionally made of titanium alloys. We must choose

A professional manufacturer specializing in the production of aluminum alloy parts.

2. Parts shape distinction

Distinguish from the shape of the parts, making plane parts and making round parts, because the respective equipment is completely different, so the quality and yield rate are also different.

3. Guarantee the depth and surface effect of etching

In order to ensure the depth and surface effect of etching, there are strict requirements for the concentration ratio of chemicals, and the uniform positioning of equipment is also a factor affecting the quality.

4. Protect the surface of aluminum alloy parts from being affected

For the surface not to be affected by chemicals, we will use electrophoresis on the surface to contact the surface with insulating potion. The electrophoretic surface and cleaning method also directly affect the quality of the surface.
