How is the plastic sealing performance of laser welding technology?

Sealing welding of plastic shells is used in many different situations. Such applications are to protect people from open water. As part of the watch design, the bracelet is equipped with sensitive sensors. Once the preset time, water depth and other parameters are exceeded, a red balloon is triggered and an audible warning signal is issued. Plastic shells such as watches require good welding seals. Let's talk about the sealing of plastics with laser welding technology.

Plastic laser weldingThe application of plastic laser welding is already very extensive and mature. Compared with traditional processing methods, plastic laser welding has the advantages of firm welding precision, strong sealing, no leakage, fast welding speed, less resin degradation, less debris, no residue, no vibration, good adaptability, etc. Based on the above advantages, plastic laser welding technology has the advantages of high welding efficiency, high appearance requirements, and wide application.

The optical path system of the plastic laser welding machine is simple, suitable for automated production, and can be directly fixed on the robot. Output power, output power, conversion efficiency, reliability and cost. Although plastic laser welding accounts for less than 20% of the market share of plastic welding processing, because the average efficiency of plastic laser welding is 2-3 times, the overall market share of plastic laser welding continues to increase, especially in some areas where high-efficiency welding is required.

In the application of sealing and welding watch plastic shells, laser welding needs to be divided into several challenges. First, to protect electronic equipment, waterproof and sealed shell parts are required. For some chemical reactions, the color of the shell and the shell needs to look the same within the wavelength range of visible light, but the shell needs to be absorbed by the laser, and the appropriate additives can be used in the plastic in the following way.

The above is the application of laser welding technology in plastic sealing process. Laser welding is mainly used in high-tech fields such as precision plastic electronic components, sterile medicine, food and medicine, and automobiles, because of the advantages and characteristics of plastic laser welding technology itself. Laser welding is widely used in mobile phone parts (casings, headphone sockets, USB sockets), mice, connectors, switches, sensors and other fields. Because laser welding can produce sealing, vacuum sterile products also perform well in the fields of medical devices and sterile environmental protection equipment.
