Principles of laser cleaning-How it works
Laser cleaning is the process of removing oxide, coating, contaminated, dust, etc. layers on metal surface by laser irradiation. By absorbing the energy of high peak pulse power laser beam, the target layer evaporates quickly. In contrast to the target layer, the metal surface below would safe without damage due to its low absorption feature.
Advantages of laser clean
Compare with traditional clean methods (i.e. chemical、sandblast、dry ice and supersonic clean, etc.), laser clean machine is an extremely gentle, faster, and eco-friendly clean method without requiring consumables. Laser Clean Machine is easy to use. It could also be integrated with automatic system to meet different applications/industry requirements, and accuracy control clean area.
Method | Laser clean | Chemical pickling | Sand blasting | Dry Ice |
---|---|---|---|---|
Contact Method | None Contact | Contact | Contact | Contact |
Damage | Nearly None | Low | High | Medium |
Accuracy | High | Low | Low | Low |
Pollution | None | High | High | None |
Consumable | Nearly None | Chemical Liquid | Aluminum steel balls | Dry Ice |
Applications of laser clean
Rust remove
Laser clean can remove rust without substrate or surface damage, environment pollution and consumable cost.
Welding Bead cleaning
Welding joint process would generate black soldiers road on surface. Laser allows for control ablation it in seconds.
Coating remove
Laser cleaning can provide high micron-sized level clean for removing coating by accuracy energy control.
Mold clean
Oxide will impact yield rate of the following processing. Compared with other methods, laser clean can efficiently remove oxide without damage and impact the accuracy of mold.
Paint-coat clean
For cleaning paint-coat, comparing with pickling of its complex process, laser clean is the high efficiency, accuracy, and eco-friendly method.
Heat treating film clean
Manual grinding is usual way to clean heat-treating film, but inefficiency and ineffective for the heavy layer. Laser clean is a better choice due to its high efficiency and accuracy.
