Compared with other commonly used welding techniques, laser welding technology produces virtually no slag and debris, and does not require the addition of any adhesive during the welding process, thus allowing the entire welding process to be completed in a clean room. Laser welding technology has greatly contributed to the development of medical devices, such as active implantable medical device shell packaging, cardiac stents radiopaque marking, ear wax protection, balloon catheters and so on are inseparable from the use of laser welding.
Plastic laser welding machine is a high-end plastic welding technology popular in recent years in China, before this, plastic welding machine are used in the traditional plastic welding methods, such as vibration welding, hot gas welding, ultrasonic welding, implantation welding, friction welding and other ways to connect the plastic before.
Laser welding is more and more widely used in various fields of medical devices due to its advantages of localized heating, precision processing and non-contact heating.
Laser welding uses a high energy density laser as a heat source irradiation in the material connection, so that the separation of the material to absorb the laser energy and rapidly melt or even vaporize and *** with the formation of a molten pool, in the subsequent cooling process together with the solidification and thus connected together. Figure 1 is the tube of the laser welding process, the red area in the figure is roughly the propagation path of the laser, the high brightness of the area is the metal after heat vaporization of the metal vapor. See here some visitors can not help but ask, where is the laser, how do I not see. This is because the laser welding with high-power laser commonly have two kinds: CO2 laser and solid state / fiber laser, the former wavelength of 10.6μm, or the wavelength of 1.06/1.07μm, are in the infrared wavelength band, so the naked eye is invisible.
The brand of the plastic laser welding machine in use is Jinan Yingyun photoelectric
