Comprehensive Guide to Surface Treatment Techniques for Vape and E-cigarette Materials
Surface treatment involves the artificial formation of a layer on the surface of the base material, which possesses different mechanical, physical, and chemical properties from the base itself.
The primary purpose of surface treatment is to meet product requirements such as corrosion resistance, wear resistance, decorative appeal, or other specialized functionalities. Commonly used surface treatment methods for e-cigarette materials include mechanical polishing, chemical treatments, surface heat treatments, and surface coating. These processes involve cleaning, scanning, deburring, degreasing, and removing oxidation layers from the surface of the workpiece. Let's explore the various surface treatment techniques applicable to e-cigarette materials.
Common Surface Treatment Techniques:
Vacuum Metalizing - Also known as Vacuum Plating, is a physical deposition process that takes place in a vacuum state where argon gas is injected to collide with the target material. This collision causes the target material to separate into molecules, which are then adsorbed onto the conductive substrate, forming a uniform and smooth metallic-like surface layer.
Applicable Materials:
Vacuum metalizing is suitable for a wide range of materials, including metals, soft and hard plastics, composite materials, ceramics, and glass. The most commonly used materials for vacuum metalizing in e-cigarette materials are aluminum, followed by silver and copper.
Natural materials are not suitable for vacuum metalizing due to the potential impact of their moisture content on the vacuum environment.
Process Cost:The vacuum metalizing process involves tasks such as spraying, loading, unloading, and respraying the components, making the labor costs relatively high. However, the cost also depends on the complexity and quantity of the workpieces.
Environmental Impact:Vacuum metalizing has a minimal impact on the environment, similar to the effects of spray coating on the surroundings.
Anodizing – Enhancing Durability and Aesthetics for E-cigarettes

Electropolishing - Enhancing Surface Smoothness through Electrochemical Process for Vape and E-cigarettes
Electropolishing, also known as electrochemical polishing, is a specialized electrochemical process used to improve the surface quality of workpieces immersed in an electrolyte solution. During this process, the atoms of the workpiece are converted into ions, and due to the passage of an electric current, they are removed from the surface. This results in the removal of fine burrs and an increase in the surface brightness, creating a polished and smooth appearance for the workpiece.
Applicable Materials:Electropolishing can be applied to a wide range of metals, making it suitable for enhancing the surface quality of various materials. Among them, stainless steel is particularly commonly subjected to electropolishing, especially austenitic stainless steel used in nuclear-grade applications.
Compatibility Considerations:It is essential to note that different materials should not undergo electropolishing simultaneously, and they should not be placed in the same electrolyte solution to avoid undesirable chemical reactions.
Process Cost:The entire electropolishing process is highly automated, which significantly reduces labor costs. As a result, the overall cost of electropolishing is relatively low compared to some other surface treatment techniques.
Environmental Impact:One of the advantages of electropolishing is its use of chemicals with relatively low harm to the environment. Additionally, the process requires only a small amount of water and is straightforward to operate. Furthermore, electropolishing can extend the properties of stainless steel, delaying its corrosion process and contributing to its enhanced longevity.
In conclusion, electropolishing is a valuable surface treatment technique that can effectively improve the surface smoothness and appearance of various metals, with stainless steel being a popular choice for this process. Its automated nature and environmentally-friendly approach make it a cost-effective and sustainable option for achieving polished and corrosion-resistant surfaces.
