Laser welding technology of hollow pepper ball is the latest manufacturing technology of hollow plastic ball. The advantage of laser welding plastic hollow pepper ball is high strength. The welding seam of hollow pepper ball is integrated with the whole plastic hollow ball, and the hollow ball welded by laser is beautiful in appearance.The welding technology of hollow pepper ball requires high accuracy of two plastic hollow pepper ball hemispheres, and two welding positions should be reserved at the welding position of the two plastic hollow pepper ball hemispheres. At the same time of laser welding, the two plastic hemispheres need to be pressurized, that is, when the joints of the plastic hemispheres melt, the two plastic hemispheres need to be pressed together by pressurization, so the tools used for welding also need high accuracy, otherwise the welded plastic hollow balls will be easily dislocated.Laser welded hollow plastic pepper balls have no special requirements on materials, as long as they are thermoplastic.The wall thickness of laser welded plastic hollow pepper ball is not required, so the wall thickness of plastic hollow pepper ball can be designed according to the required strength of hollow plastic ball.There is also a high efficiency. The laser welding speed is very fast, and a plastic hollow pepper ball can be welded in a few seconds.The welding place is beautiful, and there is basically no batch wind, which saves the material cost and brings convenience to the subsequent processing.
