The difference between laser processing and etching processing

1. The principle is different: laser processing uses the laser beam to cauterize the local surface of the medium to realize gasification and etching processing, and uses the redox reaction between substances to realize metal dissolution.

2. Different effects: laser engraving can't achieve deep engraving on metal medium and high-density substances, and the depth of metal etching can reach 0.01MM, which can realize diversified color decoration.

3. Different scope of application: the laser engraving process has a wider scope, and most media can be processed by laser. The etching process can consider aluminum, iron, stainless steel, copper and titanium alloy.

4. Different technological processes: the laser process is simple, with few processes, more etching processes and more details.

5. Different production efficiency: laser engraving is suitable for small batch processing and production, while hardware etching can be used for large batch production.

6. Different precision: the thickness of Stainless steel etching production precision is 0.01 mm.
