Most of the plastic shell pepper balls are manufactured by laser welding. Because of the poor fluidity of the materials, they cannot be produced by blow molding. Although the plastic shell pepper balls are produced by laser welding with high strength, it is easy to produce poor appearance at the weld.

The main reason for the bad appearance of the plastic shell pepper ball weld is that the melted rubber was carbonized at high temperature during laser welding, so when laser welding PC hollow ball, the time of laser welding should be strictly controlled. The longer the plastic shell pepper ball is welded, the higher the rate of bad appearance, and the choice of laser power. Too high power will also cause the carbonization of the rubber at the weld, So when purchasing the laser welding machine, you should choose the right model of the laser welding machine, so as not to use the laser welding machine you bought back, and the pepper ball with plastic shell will cause unnecessary waste.
