What are the advantages of laser welding plastic material products?

So far, the inherent thinking of laser welding machines is still stuck in the welding between metal materials. Many people don鈥檛 know that in fact, plastic materials will have better results when using laser welding in many applications. In the development history of laser welding technology, plastic laser welding has also been continuously accepted and recognized by all parties, that is, laser welding technology can not only weld metals, but also non-metallic materials. Its principle is actually the same as the laser welding process of metal materials, which is to use the laser beam to generate heat to quickly melt the plastic contact surface.

In the early days, the technology of plastic laser welding was not very mature, so its price cost was very expensive. In terms of production, one was the uncertainty of technology, and the other was the high price, which made it unable to compete with early plastic bonding, ultrasonic and other technologies. But now this problem has changed a lot. The initially expensive and immature technology is now not only reasonably priced, but also unmatched in the overall performance of traditional welding processing.

So what are the advantages of laser welding plastic material products now?

(1) Precise, firm and sealed (airtight and watertight), less resin degradation and less debris.

(2) Easy to control, good adaptability, welding small size or complex shape and structure workpiece.

(3) Greatly reduce the vibration stress and thermal stress of the product.

(4)Can weld a variety of different materials.

In addition, for some industries such as food and medical industries, laser welding does not generate residues, which makes it more conducive to food hygiene and safety and national food hygiene supervision than traditional welding methods. For laser welding, the entire welding process is controlled by computer software, so the welding is flexible and has a large degree of freedom. Even some very complex products can be easily handled by laser welding. Compared with other melting methods, laser welding can also greatly reduce the vibration stress and thermal stress of the product. This means that the aging rate of internal components of the product or equipment is slower, and it can be used for welding of fragile products. At present, laser welding technology has been widely used in medical, automotive, electronics, packaging and other fields. Its excellent performance advantages have also greatly improved the quality of plastic products. In the future, as the technology continues to mature and prices fall, this technology will be more widely used in various plastic industries.
