Laser Cleaning Machine Basics
How Laser Cleaning Works
You use a laser cleaning machine to remove rust, paint, oil, and other contaminants from automotive parts. The process relies on three main principles:
- Photothermal Effect: The laser beam heats the contaminants quickly. This causes them to vaporize or break away from the surface.
- Shock Wave Effect: Rapid heating creates a high-pressure plasma. The plasma forms a shock wave that helps push contaminants off the part.
- Thermal Stress Effect: The laser causes different expansion rates between the contaminant and the base material. This stress helps detach unwanted layers without harming the underlying part.
A laser cleaning machine gives you precise control. You can target only the areas that need cleaning. You avoid damaging sensitive surfaces, which is important for automotive components.
Benefits for Automotive Use
When you compare laser cleaning to traditional methods, you see clear advantages. The table below highlights key differences:
| Feature | Laser Cleaning | Traditional Methods |
