[Q] What are the requirements for plastic laser welding materials?
First, material type
Plastic laser welding is suitable for most plastic materials, including: ABS, AS, PC, POM, PP, PBT, PA6, PA66, PET, etc. Different materials may have different requirements for welding, so it is necessary to confirm the type of material used before performing plastic laser welding.
Two, Color
In plastic laser welding, the color will have a certain impact on the welding effect. Normally, darker colors are able to better absorb laser energy, resulting in better welding results. Lighter colors may require increased welding time and power to achieve the desired effect. Therefore, the influence of its color on welding needs to be considered when selecting materials.
Third, transparency
For transparent materials, it is necessary to choose materials with high transparency for welding, otherwise the welding quality may be affected. In addition, for thicker transparent materials, special pretreatment is required before welding, such as drilling holes or using ultraviolet laser treatment.
Fourth, material surface treatment
When performing plastic laser welding, the surface of the material needs to be smooth and clean, without impurities such as oil and dust. Therefore, the surface treatment needs to be done before welding, and the surface stains can be removed by chemical cleaning, sandblasting or grinding.
In short, when performing plastic laser welding, different materials need to consider different requirements, including material type, color, transparency and surface treatment. Only after fully understanding these requirements and making appropriate preparations can good welding results be achieved.
