Metal shell processing: a perfect transformation from design to finished product
With the rapid development of the electronic product market, metal shells are playing an increasingly important role. In order to ensure product quality and safety performance, the quality of the metal shell processing process is crucial. This article will provide a detailed introduction to the process and technical practices of metal shell processing from aspects such as design, material selection, mechanical processing, and surface treatment, and explore future development trends.
1、 Introduction: Metal shell processing refers to the process of making metal materials into shells that meet design requirements through various processing techniques. In the manufacturing of electronic products, metal shells have a wide range of applications, such as mobile phones, computers, tablet TVs, etc. Therefore, the development of metal shell processing technology directly affects product quality and market competitiveness.
2、 Background knowledge: Metal shell processing involves multiple aspects of electronic product manufacturing, such as material selection, electroplating, spraying, etc. Among them, materials such as aluminum plastic plate and copper foil lamination are widely used in electronic products. Aluminum plastic panels have high heat resistance, moisture resistance, and strong corrosion resistance, and are widely used in the shells of electronic products. Copper foil lamination has good conductivity and corrosion resistance, making it a commonly used material for manufacturing high-performance electronic product shells.
3、 Processing process
Preliminary design: Determine the shell material, structure, and dimensions based on product design requirements.
Material selection: According to design requirements, select suitable metal materials, such as aluminum alloy, stainless steel, titanium alloy, etc.
Mechanical processing: Metal materials are processed through various methods (such as cutting, planing, milling, etc.) to achieve the desired shape and structure.
Surface treatment: To treat the surface of the processed shell, such as electroplating, spraying, etc., to improve appearance quality and durability.
4、 Technical Practice
The application of hard alloy cutting tools in the processing of aluminum plastic plate shells. Hard alloy cutting tools have high wear resistance and cutting edge sharpness, which can ensure the surface smoothness of the casing. However, hard alloy cutting tools are prone to scratching the surface of aluminum plastic plates during the processing, which affects the surface smoothness.
The application of high-speed steel cutting tools in the processing of stainless steel shells. High speed steel cutting tools have good wear resistance and cutting edge sharpness, which can ensure the surface smoothness of the casing. However, high-speed steel tools are prone to chipping when cutting stainless steel, which affects the cutting effect.
The application of diamond cutting tools in the processing of titanium alloy shells. Diamond cutting tools have extremely high hardness and sharpness, which can ensure the surface smoothness and accuracy of the casing. However, diamond cutting tools are expensive and prone to damage to the surface of the material being cut during the machining process.
The application of superhard material cutting tools in the processing of polymer material shells. Superhard material tools include cubic boron nitride tools, ceramic tools and cermet tools. This type of tool not only ensures surface smoothness during the machining process, but also has a fast cutting speed, effectively improving production efficiency.
