Here will introduce more details of battery of laser pointer

So I do not use laser welding. This is a big drawback for the pharmaceutical, packaging and consumer products because these products require transparent. Finally, because many mineral-filled compounds can absorb near-infrared laser, it is usually not suitable for welding with a laser. Highly filled glass fiber reinforced material can change the transmittance of the near-infrared laser, reducing the welding efficiency, but the glass content in the raw material suppliers of the formula usually do not exceed this limit. In the automotive industry. Laser welding of plastics technology can be used to produce a lot of auto parts, such as fuel nozzles, the gearshift rack, engine sensors, cab rack, hydraulic oil tank, filter frame, headlights and taillights. The capacity of     green laser pointer is large.
Other automotive applications is also included in the manufacturing of the trachea optical manifold and auxiliary pump manufacturing. Figure 4: The laser welding technology for processing car headlights, the use of a focused laser glass sphere also play a gripping tool role. Laser welding technology can be used in the manufacture of liquid storage tanks, liquid filtration equipment, hose connectors, ostomy bags, hearing aids, graft, the analysis used in microfluidic devices, etc.. Figure 5: The laser welding technology manufacturing microfluidic devices, the use of the precise characteristics of the technology. Laser welding is a vibration-free technology, so it is particularly suitable for machining of precision electronic components. Here will introduce more details of battery of laser pointer .
Mouse, mobile phones, connecting devices and other equipment manufactured by laser technology. Laser technology to manufacture automobile electronic products, automatic door locks, key and out of equipment and sensors. The laser can also be plastic film welded together, which move along the edge of the film, a packaging seal structure formed by bonding effect. Procedure can be completed very quickly. According to the TWI company, which uses 100W carbon dioxide laser can welding speed of 100 m / min to 100 micron polyethylene film. Figure 6: Laser welding microscopic image of two polyethylene film. In the early stages of development of laser technology, the technology of two transparent plastic welding together is impossible. The use and charge description and requirement of the battery of   green laser pointer   will be introduced.
Contact between the two layers of plastic at the infrared absorption of the role of coatings, the bond between two transparent materials. Paint in the irradiation of the laser heating and melting of the adjacent layer of material, thus achieving the purpose of bonding. Figure 7: the plastic surface contact at the laser absorption coating fever and connect the transparent material layer usually can not be welded. Two layers of black plastic in the past, laser welding is impossible, this is because the laser energy has been absorbed before it reaches the welding interface. But now we can be in the upper layer of plastic to add special pigment to the naked eye looks black, but is transparent to the laser, so that the black material of the welding can be achieved. It is CR123A battery of     green laser .
Pigments to ensure that enough laser energy through the upper material so that the two layers of the contact surface melting. Laser welding of plastics technology is very specialized bonding techniques require high-speed welding and welding require precision welding or sterile conditions, which can play to the best advantage of laser welding. The technology used to be subject to the price factor, but with the falling prices of equipment in many applications than ultrasonic welding and hot plate welding more competitive. The main fields of application of laser welding technology areas such as medical, automotive, electronics and packaging. Additives and coatings technology development to overcome the limitations of laser welding technology early applications, so the depth of laser welding technology is widely used in large part thanks to their progress. And it doesn’t mean   200mw laser pointer can be used for 3000 hours after being charged.
