Laser welding plastic, the laser beam, after transmission through the upper-layer transparent material, will be absorbed by the lower layer. The laser energy, after being absorbed, will be transformed into heat. Since two layers of materials are forced together, the heat will be conducted to transparent layer from absorbing layer, which would make the two layers of materials melt and connected. At the same time, the internal pressure occurs because of the material’s thermal expansion. The total effort of the internal and external pressure can make sure two layers are firmly welded. For the product lower-layer material does not absorb laser, additive needs to be applied to the lower layer.
Almost all thermoplastics and thermoplastic elastomers can use laser welding technology. Commonly used welding materials are PP, PS, PC, ABS, polyamide, PMMA, POM, PET and PBT. However, some other engineering plastics, such as polyphenylene sulfide PPS and liquid crystal polymer, are not suitable for laser welding technology because of their low laser transmittance. Therefore, addictive is often added to the underlying material so that it can absorb enough energy to meet the requirements of laser transmission welding.
