FAQ
Why is a UV laser suitable for precision marking?
UV laser marking uses a 355nm wavelength with a very small focused spot and minimal heat affected zone. Compared with fiber lasers, it provides finer details, cleaner edges and higher contrast on heat-sensitive materials such as plastics, glass, ceramics and electronic components. It is widely used where high precision and excellent surface quality are required.
How do I choose between 3W, 5W and 10W UV laser machines?
A 3W machine is suitable for most precision marking applications on plastics, PCB and electronic components. A 5W machine offers higher productivity and supports a wider range of materials. A 10W model is recommended for higher-speed production, deeper engraving on certain materials and demanding industrial applications. Final configuration should be selected according to material, marking size and production capacity.
Can the machine mark glass and transparent plastics?
Yes. UV laser technology is especially suitable for glass, acrylic and many transparent engineering plastics because the ultraviolet wavelength is more effectively absorbed by these materials. Proper parameter adjustment helps achieve clear and permanent marks while minimizing cracking, melting or discoloration.
What is the minimum character size and line width?
The minimum marking size depends on the optical configuration, material and processing parameters. UV laser systems are capable of producing extremely fine characters and thin lines suitable for micro QR codes, serial numbers and precision electronic components. Exact values should be confirmed according to the selected configuration and application requirements.
Will UV laser marking cause thermal damage?
UV laser marking is considered a cold processing technology. The short wavelength reduces heat transfer to the surrounding material, resulting in a very small heat affected zone. This makes it ideal for heat-sensitive plastics, coated materials, electronic components and medical products that require minimal deformation.
What is the service life of the UV laser source and how is maintenance performed?
The UV laser source is designed for long-term industrial operation under proper working conditions. Routine maintenance mainly includes cleaning the optical lens, maintaining the cooling system, checking electrical connections and keeping the working environment clean. Regular maintenance helps ensure stable performance and extend equipment life.
What are the normal operating costs?
UV laser marking machines require no consumable ink or chemicals. Daily operating costs mainly include electricity consumption, cooling water maintenance and routine cleaning, making the equipment suitable for long-term industrial production with relatively low operating costs.
Which parts are considered consumables?
Under normal operating conditions, common maintenance items include protective optical components, cooling system accessories, filters and certain electrical components. Proper maintenance significantly extends the service life of the equipment.
