Nowadays, medicine supervision is more intelligent. Each medicine has its own supervision code and this code equals to the identification of the medicine. With this supervision code, every medicine is under strict control.
Supervision code of medicine is supposed to be long lasting. For if any problem happens to the specific medicine, the national medicine supervision sector can take some measures very quickly. With laser marking technique, medicine supervision will enter into an era of high efficiency and environmental friendliness.
In the past, the medicine identification code used to be finished by inkjet printer. Inkjet printer releases pressure to the internal ink by controlling the internal gear pump or the external compressed air. Then the electriferous ink will deflect and project through the nozzle to form different kinds of characters and patterns.
Since inkjet printer depends on static electricity for deflection. Therefore, when static electricity accumulates to a certain degree, there will be fire. What’s more, if the inkjet printer doesn’t have well-contact earthing, the printing quality will become poor, leading to unclear marking. In addition, the inkjet printer’s ink is corrosive and easy to volatilize, posting great risk to human’s health.
Comparing with inkjet printer, laser marking machine is more precise and more environmental friendly. It uses high energy laser light as the “pen” to “draw” the supervision code on surface of the medicine package with the combination of computer and precision machinery.
Medicine supervision code laser marking machine is often powered by UV laser which is a “cold light source”. That means it has a very small heat-affecting zone and doesn’t damage the surface of the material surface. However, it still generates heat, like all the industrial equipment does. To maintain its long-term performance, the heat must be taken away in time. S&A Teyu industrial process chiller CWUL-05 is widely used to cool the UV laser source of the laser marking machine and has attracted so many fans in the printing industries, medicine industries and other high precision processing industries.
