The Haofeng intelligent manufacturing three-station positive–negative pressure thermoforming machine is the third-generation, fully automatic, multi-station thermoforming equipment, completely upgraded by Haofeng (Tianjin) intelligent manufacturing. It is specifically designed for large-scale production of high‑requirement, multi‑category, high‑precision blister packaging. Breaking through the limitations of traditional single‑stage negative pressure forming, this machine employs an industry‑leading combined positive–negative pressure forming process and features a three‑stage workstation circulation design, effectively addressing longstanding industry challenges such as insufficient filling in deep cavities, uneven wall thickness, and defects in irregularly shaped products. The entire machine is equipped with high‑precision servo drive, segmented constant‑temperature heating, heavy‑tonnage stable punching, and an intelligent CNC control system, highlighting four core advantages: excep
