Product Overview
The Haofeng large‑format three‑station positive‑negative pressure thermoforming machine is the third‑generation, fully automatic, multi‑station thermoforming equipment newly upgraded by Haofeng (Tianjin) Intelligent Manufacturing. It is specially designed for large‑scale mass production of high‑requirement, multi‑category, high‑precision blister packaging. Breaking through the limitations of traditional single negative pressure forming, this machine adopts an industry‑leading combined positive‑negative pressure forming process and features a three‑stage workstation circulation design, thoroughly addressing industry pain points such as insufficient filling in deep cavities, uneven wall thickness, and molding defects in irregularly shaped products.
The entire machine is equipped with high‑precision servo drive, segmented constant‑temperature heating, heavy‑duty stable punching, and an intelligent CNC control system, boasting four core advantages: high forming accuracy, broad material compatibility, fast and stable operation, and convenient mold changes and adjustments. It can stably handle mainstream thermoplastic sheets such as PP, PET, PS, and PLA, and is widely used in high‑end fields like food packaging, electronic components, daily necessities, and medical packaging. It is the flagship, high‑capacity, flexible production equipment for medium and large blister packaging factories.
Machine Structure and Three‑Stage Workstation Workflow
The equipment adopts a standardized three‑stage independent workstation circulation design, separating sheet feeding and heating, positive‑negative pressure forming, and punching and stacking processes into independent yet coordinated operations. Each process runs without interference, ensuring efficient and stable operation, significantly reducing failure rates, and adapting well to long‑term continuous mass production and frequent mold‑change scenarios.
Workstation One: Precise Servo Sheet Feeding + Three‑Stage Independent Constant‑Temperature Heating
It uses a 7‑series anodized aluminum alloy chain rail paired with a servo‑driven chain sheet‑pulling system. The chain rail structure is robust and operates smoothly without jamming, delivering precise and stable sheet feeding. It supports electrically synchronized or independently adjustable bidirectional width settings, quickly adapting to different sheet widths and flexibly accommodating various product categories.
Equipped with a three‑stage independent temperature‑controlled heating furnace, featuring Japanese Yamato temperature controllers and imported heating elements, each zone’s heating module can precisely regulate temperature independently. With rapid heating and uniform heat distribution across the entire sheet, it can specifically meet the softening and forming requirements of different materials and thicknesses. The electric furnace also supports automatic removal, greatly simplifying mold changes, furnace cleaning, and equipment maintenance, effectively shortening downtime for debugging and boosting overall production efficiency.
Workstation Two: Positive‑Negative Pressure Collaborative Forming (Core Differentiating Advantage)
As the core process module of the machine, the mold base is integrally cast from high‑strength ductile iron and driven by a heavy‑duty precision planetary gearbox. The parallelism between the upper and lower mold bases can reach 0.03 mm (3丝), ensuring strong rigidity, zero operational deviation, and stable forming benchmarks throughout the machine.
It uniquely employs a two‑way collaborative forming process—negative pressure pre‑forming followed by positive pressure supplementary shaping. First, vacuum negative pressure precisely conforms the softened sheet to the basic contour of the mold; then, positive pressure airflow reinforces and fixes the shape, perfectly resolving the shortcomings of traditional single negative pressure forming, such as insufficient filling in deep cavities, missing edges, uneven wall thickness, and product deformation. The machine also supports servo‑assisted upper mold stretching, allowing precise adjustment of forming depth, suitable for both standard shallow cups and boxes as well as high‑precision forming of deep cavities and complex irregularly shaped blister products. Finished products exhibit uniform weight, rich details, and extremely high yield rates.
Workstation Three: Heavy‑Duty Precision Punching + Fully Automatic Stacking and Discharge
The punching workstation features a dual‑chain lifting mold platform structure paired with a stepped lubrication distributor, ensuring smooth operation and even cushioning throughout, completely eliminating punching vibration and misalignment issues. Its maximum cutting force reaches 120 tons, providing ample load capacity to stably handle precise punching of large‑format, complex die lines, and high‑strength blister products. Cut edges are smooth with no burrs, and dimensional accuracy is consistent.
Equipped with a dedicated automatic forming clamp frame, the machine’s sealing performance is greatly enhanced, effectively preventing air leakage and material shortages during forming, thereby improving the final product qualification rate at the source. At the end, an intelligent robotic arm suction‑stacking system automatically counts finished products, neatly stacks them, and continuously discharges them, adapting to various size specifications and directly interfacing with downstream automated packaging lines to achieve fully unmanned operations.
Intelligent CNC Control System
The machine is equipped with a high‑end CNC control system superior to traditional PLCs, featuring an 8‑axis handwheel with precise mold alignment functions, making debugging intuitive, convenient, and highly accurate. It can store over 500 sets of mature process parameters, enabling one‑click parameter recall and one‑click mold changes, perfectly suited to flexible production scenarios involving multiple product categories, small batches, and frequent switching.
The system includes built-in intelligent self‑diagnosis and remote monitoring functions, allowing real‑time tracking of equipment operating status and precise fault localization, significantly reducing equipment maintenance difficulty and costs. It supports free switching between manual and automatic modes, balancing automated mass production with the need for manual fine‑tuning during new product development, adapting to various production conditions.
