What is the marking effect of UV laser on plastic products


Nowadays, plastic products have become indispensable and widely used in life. Compared with wood, stone, metal and other materials, plastic products have the advantages of low cost and wider application scenarios.



Although plastic products are very common, not everyone knows that, in fact, plastic products have very strict classification standards and usage specifications. If used improperly, it will endanger our health.

Among these categories, the most frequently contacted are: PET (polyethylene terephthalate), which is generally used for filling mineral water, carbonated beverages, fruit juices, etc.; HDPE (high density polyethylene), because of its excellent Corrosion resistance, generally used in the production of color medicine bottles, opaque shampoo bottles, yogurt bottles, chewing gum bottles, etc. PVC (polyvinyl chloride) is generally used in the production of raincoats, PVC plastic pipes, water pipes, plastic switches, sockets, etc.

Regardless of the material, marking is indispensable in processing. In addition to prompting and anti-counterfeiting, plastic marking also plays a significant role in the design of plastic products. At present, laser marking is gradually replacing traditional printing methods and becoming the first choice for plastic marking.


Compared with traditional marking technology, the application of uv laser marking on plastic products has the characteristics of high temperature resistance, strong light resistance, corrosion resistance, water resistance, and scratch resistance. More importantly, laser marking can ensure that the material itself is not damaged and damaged to the greatest extent, and the operation is more convenient, and the process is more environmentally friendly.


RFH laser has done a lot of research and exploration on the marking of plastic products. The S9 series of UV laser products of RFH laser have excellent performance in plastic marking. The following is the marking application of RFH laser on plastics.

RFH S9 series ultraviolet laser can perfectly mark the serial number, product production date, product copy, LOGO, barcode, two-dimensional code and other elements on plastic products. Its marking effect has the characteristics of fast speed, high efficiency, and clear imaging. Distortions, black fonts, and blurred patterns may occur. At the same time, the RFH S9 series laser can make the laser marking of plastic products more stable due to its excellent beam quality and higher pulse frequency, and finally presents a marking effect with uniform lines, strong contrast and fine patterns.

"Small size", "±0.02mm high precision", "high power stability", and "high cost performance" are the core advantages of RFH S9 UV lasers. 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 produce lasers of different powers, and the stability of different power ranges is greatly improved.


The new product series of RFH pulsed ultraviolet solid-state laser S9, the laser wavelength is 354.7nm, the repetition frequency coverage is wide (single pulse to 200kHz), can be absorbed by the material, and the material is less destructive, and has superior beam quality M2<1.2 ), strictly guaranteed in all frequency ranges. The pulse width is less than 20ns@30k, and the heat-affected area is very small during processing. RFH S9 UV laser is the best solution for laser marking of plastic products!



RFH Laser is committed to providing you with the best product experience and the most complete after-sales service. With 15 years of experience and a huge technical team of experts, RFH looks forward to providing you with stronger and better laser technology!
