Plastic button switch laser marking, why are RFH UV lasers used?

RFH UV laser allows you to witness different plastic switch marking technology

Plastic switches exist in all aspects of our lives. For example, they are widely used in smart intercom system switches. For the plastic switch of the intercom-only system, it greatly ensures that the wiring attached to it is well protected, and will not be easily damaged or broken, and will not be easily exposed to water or open flames.


Many plastic switches require text and patterns in class. In addition to controllable size and shape, the engraved text and patterns can also ensure that even if the text is small or large, it will never overlap in a small area and make it unclear. And after a long time of use, the text and patterns on the plastic shell will never be blurred or distorted, so that users do not have to worry about losing guidelines or instructions, which can extend the life of the product and effectively guarantee the quality of the product.


Because of this, more and more manufacturers use UV laser marking machines to mark text and patterns on plastic switches. Ultraviolet laser has a very small focus spot and a small processing heat-affected zone, so there is almost no damage caused by heat, so it is called a cold light source. Because of the extremely small heat-affected area of ​​the UV laser, there is no thermal effect, and the deformation or scorching of the processed material is avoided.

Professional manufacturer of UV lasers, Shenzhen RFH.


With 13 years of ingenuity, RFH developed and produced the S9 series of nanosecond ultraviolet lasers that can engrave clear writing on the mouse and keyboard. This kind of handwriting can not only help identify different keys, but also ensure that it will not be blurred or faded after long-term use. The slight protrusion can help the user to distinguish the keys by touch in a darker place. It is practical and long-lasting. Make some progress.


The professor-level team at home and abroad independently develops the laser dedicated power control system to reduce the failure rate

There is a one-to-one correspondence between the power supply and the laser. The stability of the power supply control system determines whether the laser can maximize its performance during operation. RFH has the advantages of independent research and development of power supply technology, which can update the function modules of the power control system in time, and improve the function modules according to the needs of the laser. 12 years of R & D technology accumulation, domestic and foreign experts, doctoral level R & D team.

This is a solid backing for the stable operation of RFH's entire laser system.

Rigorous production system and dust-free production workshop are the cornerstones of forging high-quality green lasers

From procurement-pre-production quality inspection control-rigorous assembly process-finished product testing-warehousing quality inspection-pre-delivery inspection-after-sales service, each level is checked to ensure stable quality and consistency of equipment parameters with actual operating parameters. The clean production environment ensures that all electronic components are produced dust-free and free from pollution. This is the reason why the service life of RFH brand lasers is better than that of peers.

"Small size", "±0.02mm high precision", "high power stability", and "high cost performance" are the core advantages of RFH S9 UV lasers.

Compared with products of the same type, S9 series lasers are smaller in size, exquisitely designed, and more stable in light output. The compact design is not only simple to save space and convenient to move, it can also prevent users from making large optical paths, which greatly reduces production and processing costs.


The new S9 has excellent quality and strong competitiveness. The laser has a wavelength of 354.7nm and a wide range of repetition frequency (single pulse to 200kHz), which can be better absorbed by the material and is less destructive to the material. The superior beam quality (M2<1.2) can be strictly guaranteed in all frequency ranges; the pulse width is <20ns@30k, and the heat-affected area during processing is extremely small.

The S9 series also adopts unique Q-adjusting control technology, and uses fully digital intelligent power supply to control the operation. It is easy to operate and comes with an internal cavity self-purification system, which has a longer life, more stable operation and low maintenance cost.
