Some customers want to know whether fiber laser marking machines can mark plastics. In order to clarify this issue, let’s take a look at what materials fiber laser marking machines are suitable for marking.
Fiber laser marking machines can be used for metals and a variety of non-metallic materials, high-hardness alloys, oxides, electroplating, coating, ABS, epoxy resin, ink, engineering plastics, etc. It is mainly used in fields with high requirements for depth, smoothness, and precision, such as watches, mold industry, bitmap marking, etc.
So the fiber laser marking machine can mark plastics, but not all plastics, only some, such as ABS plastics. For some plastics, you may need to adjust the power, speed, and frequency several times to achieve the desired effect. But plastics are prone to bubbling, so it depends on the specific material of your plastic. You can only try it slowly by yourself. Adjust the power and frequency at five values, and the speed at five hundred values. Each time you adjust, fix two parameters and only adjust one parameter. If you really can’t adjust it, then use a CO2 laser marking machine, which is specially used for marking non-metals.
In addition, many customers are also worried that fiber laser marking machines will burn plastics. There is no need to worry about this, because the output power of fiber laser marking machines is usually not high. As long as the parameters are adjusted correctly, the laser will only evaporate a thin layer on the surface of the plastic, and will not burn the plastic itself. If you want to mark plastics but don’t know whether to purchase fiber or Co2 laser marking machines, just remember one thing: generally, fiber lasers work well on hard plastics, such as pe, pvc, pp, etc., and Co2 can also be used, but the effect is worse. It is recommended to communicate more with the manufacturer before purchasing.
