There is a bit difference between laser etching and laser engraving machine. Laser etching is the process in which the machine melts micro surface to create raised marks and engraving removes material surface to create deep marks. Both processes are important in part traceability. Laser etching process create heat to melt micro surface then it expand and create texture. Laser etching create permanent black and white marks. Also, due to less energy consumption etching process is faster than engraving.
Applications of laser etching machine
A Fiber laser etching machine is used to mark all types of barcodes, data matrix codes, and QR codes but also serial number and data matrix code.
The most common applications of this marking machine are:
Metal industry
Laser etching has great importance in the metal industry. It is used in the traceability program which helps in optimizing the process of smelters and die casters. Also you need etching for any part made of metals except stainless steel.
Medical industry
According to FDA regulations, it is important to identify to identify medical devices. most medical devices can be identified with unique identifiers.
Automobile industry
In car manufacturing industry, manufacturers have been required to trace their suppliers.
When do you need etching?
- When you need faster etching process.
- When you need cost effective laser that require less laser power.
- It focus on small area of the material known as focal point.
Laser etching machine price
Laser etching machine price vary from manufacturer to manufacturer. The initial price range of this machine is 2 lakh. The price may go up to 5 or 6 lakh depending on the material and technology.
Frequently asked questions
Q1. How much etching and engraving depth differ?
Ans. Etching creates very low depth as compared to engraving. The laser etching depth is 0.0001 inch and the engraving depth is 0.0001 to 0.005 inch.
Q2. Where do we use laser etching?
Ans. we use laser etching to mark:
- text
- logos
- serial numbers
- bar codes
- time and dates
- and other manufacturing information
Q3. does etching create permanent mark?
Ans. Yes, it create permanent mark on the metal surface.
