I believe many people have had this experience, tear open a bag, there are obviously opening lines, but they always can not be torn, not neat. This is not the fault of the hand, but the fault of opening process at that time. With the development of science and technology, the emergence of laser drilling technology has solved a series of problems caused by the traditional opening process.
Laser drilling is used to illuminate the processed material with a high power density laser beam, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. Laser drilling is the earliest practical laser processing technology, and it is also one of the main application areas of laser processing.
Laser drilling has the following significant advantages:
①Laser drilling speed is fast, high efficiency and good economic benefits.
②Laser drilling can obtain a large depth-to-diameter ratio.
③Laser drilling can be performed on various materials such as hard, brittle and soft.
④Laser drilling without tool loss.
⑤Laser drilling is suitable for large number and high density group hole processing.
⑥Small holes can be machined on the inclined surface of difficult-to-machine materials by laser.
Micron level fine light output, according to the set procedure, scribe or punch holes on the surface layer of a specific packaging film to make the surface layer easy to tear line opening. So the inner seal is intact. In this way, not only the effect of easy tearing can be achieved, but also the function of sealing the inner layer can be achieved.
Sino-Galvo Tech. was founded in 2001, and our galvanometer scanners already have got CE, ROHS, FCC and REACH certifications, quality control in accordance with ISO9001 quality system standard, and we exported our products to many countries and regions.We also provide complete marking system including fiber laser marking machine, CO2 laser marking machine, production date batch number serial number laser marking machine and other laser equipment.
