Angle Cleaning in Metal Surface Treatment    

1. Importance  

• Ensuring thorough cleaning of all angular areas of metal parts is the foundation for successful subsequent processing. It affects the product's appearance, performance, and service life.  

2. Difficulties and Challenges    

• Angular areas are hard to reach, making it easy for contaminants to accumulate and difficult to remove. Different metal parts have complex shapes, requiring customized cleaning solutions.  

3. Cleaning Methods    

• Traditional methods: Manual scrubbing and sandblasting, suitable for simple or small-scale production.  
• Modern technologies: *Ultrasonic cleaning: Efficiently penetrates tiny gaps, suitable for complex shapes.                                                                                                                                                                                                                                                                                         *Laser cleaning: Environmentally friendly and efficient, with no chemical pollution, suitable for high precision requirements.  

4. Cleaning Steps  

• Pre-cleaning: Remove most contaminants from the surface.  
• Key cleaning: Focus on angular areas for meticulous treatment, ensuring no dead corners.  
• Post-treatment and inspection: Ensure overall cleanliness and conduct quality checks.  

5. Precautions  

• Choose appropriate cleaning methods to avoid damaging the metal substrate.  
• Emphasize environmental protection, reducing the use of chemical cleaners.  
• Strictly adhere to safety operating procedures to ensure the safety of personnel and equipment.
