When we usually buy things, we pay special attention to the production date of the goods, especially food. Use the production date to compare the shelf life to identify whether the product has expired. If it expires, you cannot buy it. There are many styles of production date on current products, and inkjet and laser marking are the main two.

3W5W UV laser marking the production date of soy sauce plastic bottle caps

UV laser damage-free marking plastic

 

When we usually buy things, we pay special attention to the production date of the goods, especially food. Use the production date to compare the shelf life to identify whether the product has expired. If it expires, you cannot buy it. There are many styles of production date on current products, and inkjet and laser marking are the main two.

 

Friends who observe carefully will find the difference between the two styles: the surface of the inkjet code is flat, and it will be worn away if there is more contact friction; the laser marking surface is recessed and is not easy to be worn away. These differences arise from the differences between their processes.

 

Inkjet printing uses ink jet printing. The ink is a chemical dye, which will oxidize and fall off after a long time, or be worn off by artificial factors (bad merchants use this to refurbish expired products, which seriously damages the rights and interests of consumers). The coded information "disappears"; while laser marking is non-contact, the high-energy laser instantly burns the flask body and cap and other parts to produce scoring information, which will not be worn away due to oxidation or other factors.

 

Because of this difference (in fact, it is a shortcoming), inkjet coding has gradually withdrawn from marking the production date of commodity outer packaging, and laser marking has gradually become the mainstream.

 

In addition, different materials have different types of laser marking applications. For example, soy sauce plastic bottle caps should be cold-processed and marked with UV lasers.

 

However, even for similar lasers, the quality is different, and the marking effect is also different. Consumers can see clearly on the outer packaging of the product. If you find that the processing effect of the factory next door is better, it is likely that the laser used in his marking machine is high-end, such as RFH ultraviolet laser.

 

RFH's 3W-5W Expert II 355nm UV laser is the royal laser of many UV laser marking machine manufacturers. It has a short pulse width (<14ns@30K), superior beam quality (M2<1.2) and perfect spot characteristics (spot ellipticity>90%), and can maintain consistent performance under extreme industrial and scientific research conditions Stable quality, so the marking speed is fast and the efficiency is high. Moreover, it has unique Q-switching control technology, which is suitable for various laser application control needs. In addition to marking the production date of soy sauce plastic bottle caps, it can also be competent for other purposes. At the same time, it also contains an internal cavity self-purification system, which makes the laser long life.

 

RFH has been deeply cultivated in the brand for 12 years and is recommended by users.
