Cold light source UV laser can avoid heat deformation of PE film when marking date

PE film has a density of about 0.92g/cm3, good heat-sealability, waterproof and moisture-proof; low tensile strength, high tensile elongation, easy to wrinkle, and more easily deformed when heated. Therefore, when drying, the surface temperature of the film should not be too high (within 55 degrees). PE film can be used as the inner layer of food bags, clothing bags, composite bags, and packaging for cosmetics, pickles and pastries.

Because PE film is easily deformed by heat, when marking the bar code or production date on its surface, it is necessary to use an ultraviolet laser with the title of the father of cold processing for marking. The wavelength of the UV laser is 355nm, the beam quality is good, the focused spot is small, and the processing heat-affected zone is small. It is especially suitable for ultra-fine marking and marking of PE film materials. It will not produce thermal effects and will not cause material scorching problems; fast marking speed , High efficiency; stable performance, small size, low power consumption and other advantages.


Based on 13 years of solid-state laser research and development experience, RFH has newly launched S9 series pulsed ultraviolet solid-state lasers for PE film coding applications, which are smaller in size, more refined in design, and more stable in light output. The small and exquisite design means that the user of the marking machine does not need to make a large optical path, which can greatly reduce the cost, save space, and be lightly installed in the field of flying marking equipment. The S9 ultraviolet laser is not only compact, but also has a more stable cavity structure and stronger scalability than similar products. The same cavity can generate lasers of multiple powers, and the stability of different power ranges is greatly improved.


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


To be able to forge such high-quality products, let's approach RFH together.


All S9 UV laser products are produced strictly in accordance with the "Quality Management System" regulations

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. This is the reason why the service life of RFH brand lasers is better than that of peers


S9 UV laser is produced in a dust-free workshop

The clean production environment ensures that all electronic components are produced dust-free and free from pollution.


A team of professors at home and abroad independently researched and developed S9 UV laser dedicated power supply control system. The power supply and the laser have a one-to-one correspondence. 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. 13 years of R&D technology accumulation, domestic and foreign professors, doctoral level R&D team. This is a solid backing for the stable operation of RFH's entire laser system.

 Power supply + laser head + cooling system, complete system sales From the user's point of view, RFH has launched a complete laser system sales program to ensure the stability of the entire laser system and its best performance


 The S9 UV laser adopts a fully digital display, supports communication with a computer, and can remotely monitor the laser. The integrated compact design facilitates equipment integration.
