0.68 cal TPX plastic hollow pepper balls are made by mold laser welding technology, but because TPX plastic hollow pepper balls are highly transparent plastic pepper balls, the appearance of TPX plastic pepper balls will be affected by a little color difference at the seams during the manufacturing process.

The color difference at the joint of TPX plastic pepper ball is mainly caused by the high laser temperature setting and the long laser irradiation time at the joint when the plastic hollow pepper ball is welded by laser. The solution is to lower the temperature of the laser welding machine and shorten the laser welding time. By adjusting the temperature and time of the laser welding machine, the phenomenon of color difference at the joint of TPX plastic hollow pepper ball can be well solved.
