Injection Blow Molding (IBM) machines rely on precise mechanical coordination among three core stations: injection parison forming, blow molding shaping, and product ejection. The rotary indexing table serves as the central rotating carrier of the entire IBM machine, responsible for accurate station switching and fixed-angle positioning of molds and workpieces. Its positioning accuracy directly determines
