With the continuous expansion of the application scope of plastic hollow ball, the past manufacturing technology of plastic hollow ball can no longer meet the quality requirements of the latest plastic hollow ball. Under the technical conditions that plastic hollow ball needs high pressure resistance and high strength, the hollow plastic ball produced by traditional blow molding process can not meet the technical requirements of this kind of plastic hollow ball at all.Through years of research and development, Dongguan Jiaji Plastic Products Co., Ltd. has introduced laser technology into the manufacturing process of plastic hollow balls, and also subverted the whole manufacturing process of plastic hollow balls. The advantage of laser plastic hollow balls is that all thermoplastic plastics can be used to produce hollow plastic balls, and the material range of hollow balls is expanded, and the use range of plastic hollow balls is wider.Laser welding hollow plastic balls, first of all, two semi-circular hollow plastic balls should be produced, then the two semi-circular hollow balls should be put together, and then the semi-circular hollow balls should be placed under the laser workbench for welding. A rotatable shaft should be installed on the laser workbench, and the hollow plastic balls should be welded while rotating. When a rotation cycle is completed, the hollow plastic balls will be welded.
