Sheet metal shell processing is a complex process that may encounter some common problems. Here are some common problems and their solutions.

1. Shell deformation: Due to the easy deformation of sheet metal materials during processing, the shape of the processed shell does not meet the requirements. The solution can be to use more stable fixtures during the machining process, adopt appropriate cooling methods, and avoid excessive heating of the material.

2. Scratching: Scratching is prone to occur during cutting, punching, and other processing of the shell, which affects the surface quality of the shell. The solution can be to adjust the angle of the tool, change the cutting speed and pressure of the material, or add a protective layer to the cutting area.

3. Welding issues: The welding joints of the shell may have problems such as uneven welds and insufficient welding strength. The solution can be to use appropriate welding equipment and processes, improve welding operation techniques, and select more suitable welding materials.

4. Surface treatment issues: The surface treatment of the shell can affect its appearance and corrosion resistance. Common problems include surface oxidation, coating peeling, etc. The solution can be to optimize the surface treatment process, increase the thickness and corrosion resistance of the surface treatment layer.

5. Dimensional deviation: The dimensions of the shell after processing may not meet the design requirements, resulting in deviations. The solution can be to strengthen the measurement and control process, use higher precision processing equipment, adjust processing parameters, etc.

6. Sound issue: Some casings may produce noise during use, affecting the effectiveness of the product. The solution can be to add noise absorbing materials, improve the design structure, and reduce friction with other components.

7. Durability issues: The casing used in harsh environments may experience oxidation, corrosion, and other issues that affect its durability. The solution can be to choose materials with good corrosion resistance, perform surface treatment, and design reasonable protective measures.

8. Safety issues: Hazardous materials such as solvents and power sources may be involved in the processing of the casing. The solution can be to strengthen labor protection measures, adopt safe and reliable equipment and processes, and provide necessary training and guidance.

9. Environmental issues: Shell processing involves environmental issues such as wastewater and exhaust gas. The solution can be to reasonably control the discharge of wastewater and exhaust gas, adopt environmentally friendly equipment and processes, and strengthen the treatment and recycling of waste.

The above is an introduction to common problems and solutions in the process of sheet metal shell processing. During the processing, it is necessary to constantly summarize experience and improve processing technology to ensure the quality and performance of the shell.
