PA pepper ball shell is produced by laser welding technology, which is also the most advanced production technology of PA pepper ball shell at present. The laser welding of PA plastic pepper ball shell requires high hemispherical accuracy, and the welding position should be reserved at the hemispherical joint of PA pepper ball shell. Only in this way, the strength of welded PA pepper ball shell will not be affected and the appearance will be beautiful.The laser welding of PA plastic pepper ball shell needs a set of special tools to produce, that is to say, when welding, it is necessary to pressurize the two hemispheres and press the melted rubber together. Only in this way can the PA plastic pepper ball shell fuse into a whole, ensuring that the PA plastic pepper ball shell has sufficient strength. Because the PA material has high temperature resistance, it is also very important to set the welding temperature of the laser machine during laser welding. If the temperature is too high, the PA material will be burnt. The welding position becomes black, so the welding is not qualified in both strength and appearance. Therefore, the laser welding of PA plastic pepper ball shell needs good technicians to operate in the selection and setting of laser machine.
