In this paper, the theoretical researches on polymer blow molding carried out in our team are summarized in terms of the modeling and simulation of the three stages during the blow molding （ namely, parison formation, parison inflation, and part cooling） and the control strategy of blow-molded part thickness. Then, four kinds of blow molded machines and key technologies with proprietary intellectual property rights, which were developed based on the theoretical researches, are emphatically analyzed. They are the air-traction three-dimensional blow- molding machine and technology, the intelligent control system and technology for the blow-molded part thickness, the key system and technology of the electrically-driven blow-molding machine, and the fast thermal cycling system and optimization for blow mold. Finally, the four blow molded machines and key technologies are integrated, thus saving the energy and material in the process of the blow molding of complex industrial parts.
