The manufacturing process of nylon plastic hollow ball is difficult to break through the field both at home and abroad (BB, Airsoft, BBS) the traditional production of nylon plastic blow molding hollow ball is not complete, the main reason is the nylon material in the molding require very high temperatures, but also have good toughness of nylon, so no matter in passing blow plastic ball or blow mold temperature, the air pressure can bring the nylon plastic blowing hollow plastic ball with a standard shape, so the traditional production process of nylon blow molding hollow plastic ball is unable to do so, Dongguan Jiaji plastic products limited company through the development and efforts of several years, (BB, Airsoft BBS) by the addition of a production technology to produce high precision plastic, nylon hollow plastic ball hollow ball shell controllable, simple technique in two parts, the first part of the two round of the output of Mr. Hollow nylon plastic hemisphere (BB, Airsoft, BBS) two hollow plastic hemisphere a clasp, can put two on the nylon hollow hemisphere fastened together, completed the first step, the second step is to be done with plastic ball ultrasonic fusion machine, ultrasonic machine completes the plastic ball fusion system. Can the heat generated in the production of ultrasonic ultrasonic, the moment the two hemispheres together, the use of this technology in producing nylon plastic hollow ball factory is the main production process is not very stable (BB, Airsoft, BBS) of the machine and the requirements of the operator is very high, the company has a professional production and technical personnel long term production of nylon hollow plastic ball, accumulated a lot of experience, and look forward to the customers demand.
