Both the mobile phone metal casing and the electronic cigarette metal shell require surface treatment after CNC precision machining, and put on a gorgeous coat for them, which not only looks good but also increases the performance of the electronic cigarette metal shell itself, such as: Anti-corrosion, rust removal, etc. The commonly used metal for the metal shell of electronic cigarettes is aluminum, but there are many materials that use zinc alloy, stainless steel, glass, ceramics and other materials as the shell. This article mainly talks about the surface treatment of the metal casing of electronic cigarettes. I hope you will gain something after viewing.
1. Anodizing
Anodizing is most common in the electronic cigarette metal shell made of aluminum alloy. This surface treatment uses alloy (or metal) as the anode for oxidation, and electrolysis is used to form an oxide film on the surface of the electronic cigarette metal shell. The surface of the smoked metal shell will form a smooth matte effect, which not only improves the corrosion resistance of the material itself, but also improves the wear resistance and material hardness. At present, anodizing is the most widely used and environmentally friendly non-toxic surface treatment technology on the market.
2. Sandblasting (bead spraying)
Because sandblasting has the characteristics of no fingerprints, not easy to scratch, non-slip and anti-sweat, it is favored by handheld electronic products. It uses the fully automatic high-speed sandblasting process to compress air to generate power to eject high-speed jets, which can remove stains on the surface of the electronic cigarette metal shell, and at the same time enhance the composite force of the electronic cigarette metal shell and the coating, so that the durability of the coating film Increase 4-5 times. For example: Juul, IBACCO 2.0, etc. have adopted sandblasting surface treatment.
3.PVD
PVD uses physical methods to vaporize the material source-solid or liquid surface into gaseous atoms, molecules or part of ionization into ions, and deposit a film with a certain special function on the surface of the substrate through a low-pressure gas (or plasma) process . The surface treatment of PVD can make the surface texture of the electronic cigarette metal shell of the product outstanding. For example: Linx, iPhone XS and other electronic products have used PVD.
4. Laser
Laser is the use of laser engraving technology to remove the material on the surface of the Electronic cigarette metal shell by using the laser high temperature to achieve the surface treatment process of engraving characters and patterns. It can keep the processed LOGO or text with no trace, smoothness and no wear.
5. Mirror polishing
In order to make the electronic cigarette metal shell smoother and have a good radiation effect, chemical or physical machinery will be used to reduce the surface roughness of the material to achieve a mirror effect. Due to the different requirements of the product on the degree of fineness, it can be divided into: cloth wheel, nylon wheel, hemp wheel, and water milling process to choose from.
Suggestion: Use cloth wheels and nylon wheels for grinding with low requirements. On the contrary, for higher requirements, you must use hemp wheels and water milling processes.
Summarize
Of course, the popular ones are the metal drawing used by ASVAPE S.ONE, the IML used by SMOORE, and the spraying used for EVOVE lite. The high-end electronic cigarette metal shell depends on the choice of surface treatment. The company undertakes electronic cigarette metal shell machining and surface treatment processing, and there are more than 15 surface treatment processes for you to choose from. Hope this sharing can bring you some gains.
