To mark the QR code of plastic bottle caps, choose nanosecond solid-state lasers.

In the hot summer, people always have a variety of cold drinks in their lives: milk tea, cola, sprite, iced black tea, etc. Some people even regard "ice cola" as an artifact of summer life. People who don’t drink one or two bottles of ice cola a day can do so. It's as if it's going to be melted. Therefore, in the summer, one or two boxes of Coke and Sprite, or a cup of milk tea are sold out every day.

While enjoying a cool summer ice drink, you can also scan the QR code on the cap of the drink bottle to win a prize.

As the ancients said, "Trees do not grow straight if they are not repaired; people do not learn and have no knowledge. Today, I'm going to show you how the QR code on the cap of the popular science bottle is made.

If you are careful, you will find that most of the beverage bottles are now made of plastic materials. One is that it can save costs, and the other is that it is also convenient to mark on plastics. However, plastics are easily deformed by heat, so UV lasers need to be used for marking.

The ultraviolet laser has a wavelength of 355nm, low thermal influence, marking on plastics, will not be deformed and burnt, safe and environmentally friendly, no consumables, no pollution, no harmful substances, in line with the green environmental protection concept promoted by the country, therefore, marking on plastics The industry has an unparalleled location.

   The 355nm UV laser forged by RFH Seiko in 13 years has been popularized in the field of plastic marking by virtue of the advantages of "±0.01mm high precision, high power stability, and super cost-effective".

   Good products must go through thousands of trials!

How many inspections does RFH's high-quality 355nm UV laser go through before shipment?

Quality inspection and control before production: each component is tested to ensure that the components are 100% qualified before it can enter the production material reserve; early-stage wiring-testing and sealing-debugging, layered checks, quality assurance; finished product testing: all products have passed Strict aging test, product parameters such as power, beam quality, spot ellipticity, beam pointing stability, etc. must be 100% up to standard; warehousing quality inspection: strictly in accordance with the "product warehousing inspection standards", the machine parameters and accessories conform to 100% Only allow storage; pre-delivery inspection: turn on again to test the equipment power, spot ellipticity, beam direction, and other parameters, and the accuracy rate is 100% before delivery.

It is this multiple detection that allows the RFH 355nm UV laser to maintain constant beam quality and high-efficiency power consumption under extreme industrial and scientific research conditions, and it has conquered many domestic and foreign laser equipment manufacturers with its high speed and fine effects. , Is used to manufacture a variety of high-precision laser marking equipment such as food packaging laser marking machine, pharmaceutical packaging laser marking machine and so on.

Of course, it also depends on what technology the laser has.

The RFH 355nm ultraviolet laser has a self-developed fully digital intelligent power control technology, which can update the power control system function modules in time, and improve the function modules according to the laser needs to ensure the stable operation of the entire laser system; it has a unique Q-switching control technology, suitable for all This kind of laser application control needs; has an internal cavity self-purification system, which makes the laser long life and stable operation.

This high-quality UV laser has accumulated 13 years of deep cultivation of RFH.
