PC hollow plastic pepper ball can only be manufactured by laser welding process, because PC molding processing temperature is high and it is not suitable for blow molding process. The most easy problem of laser welding hollow plastic pepper ball is that the welding position becomes discolored and yellow.

To solve the problem of yellowing of PC hollow plastic pepper ball during laser welding, we should first find the reason from the parameters of the laser welding machine, because too much power adjustment during laser welding will cause the glue to yellow due to high temperature during welding. Adjust the parameters of the laser welding machine from the minimum value, and increase the power of the laser welding machine little by little according to the appearance effect of the welded PC hollow plastic pepper ball. Only in this way can we find the best parameters and ensure the quality of the hollow plastic pepper ball.
