Several common plastic materials include ABS plastic (acrylonitrile butadiene styrene), PP plastic (polypropylene), PS plastic (polystyrene), PPS plastic (polyphenylene sulfide), and PP (polypropylene). For semiconductor laser marking, >laser marking machines, fiber laser marking machines, and CO2 laser marking machines can all be used to mark plastics (regardless of the material), but Zhongtian Laser recommends using the Zhongtian CO2 laser marking machine.

1. Using plastic for Zhongtian fiber optics can easily cause objects to discolor, while CO2 is less likely to cause discoloration.

2. The price of Zhongtian fiber laser marking machines is high. Fiber laser marking machines of the same power are twice as expensive as CO2 ones. For example, a 10W CO2 laser costs 30,000 yuan, while a 10W fiber laser costs 60,000 yuan.

3. The effect of CO2 laser is better than that of fiber laser.

After deciding to use a CO2 laser marking machine, what power level should be chosen??

Actually, there's no standard approach to power, as it depends on your specific requirements such as marking speed and material purity.

1. The faster the speed, the higher the power requirement

2. Regarding material quality, Zhongtian previously worked with a client who specializes in manufacturing lubricant barrels. The client presented two barrels of the same model and material, but different colors. The blue barrel was easily marked using a 10W machine, whereas the red one showed poor marking results with a 10W machine, necessitating the use of a 20W CO2 laser marking machine. The reason behind this is that the red barrel contained more impurities, indicating that the purity of the material in the two barrels differed.
