Product Overview
The Haofeng three-station negative-pressure thermoforming machine belongs to the Haofeng HF/SE series of economical, mainstream blister-forming equipment. It is a fully automated mass-production model specifically designed for shallow-cavity, medium-deep-cavity, and non-perforated general-purpose blister packaging. The machine employs a mature industry-standard three-station integrated process, integrating heating, negative-pressure forming, cutting, and stacking into a fully automated workflow. By eliminating complex, redundant structures, it emphasizes four core advantages: stable operation, simple operation, high cost-effectiveness, and low maintenance costs.
This machine features a proprietary pure negative-pressure forming process with no positive-pressure air-supply structure, ensuring gentle, stable forming that minimizes material breakage, produces uniform wall thickness, and maintains consistent product weight. It is compatible with conventional thermoplastic sheets ranging from 0.2 to 1.5 mm thick, such as PP, PET, PS, PE, and PLA, and is widely used in food packaging, daily-use packaging, electronic-industry inner trays, biodegradable eco-friendly products, and other general applications. It is the preferred mainstay equipment for small and medium-sized packaging factories seeking standardized, low-cost, 24-hour continuous mass production.
Machine Structure and Three-Station Sequential Workflow
The Haofeng three-station negative-pressure thermoforming machine adopts a three-stage sequential operation—servo-driven sheet feeding and heating, negative-pressure vacuum forming, and cutting and stacking for discharge—integrated into a single unit without separate connections. This streamlined process results in low failure rates and strong mass-production stability, enabling fully automated closed-loop production.
Station One: Servo Sheet Feeding + Multi-Zone Constant-Temperature Heating
The machine is equipped with a high-precision servo chain sheet-drawing system that supports electric width adjustment, automatic deviation correction, and full-range tension closed-loop control, ensuring smooth, precise sheet transport while preventing misalignment or uneven tension. It also features dual-sided infrared heating ovens with independent multi-zone temperature control, providing uniform heating across the entire sheet surface and accommodating various materials and thicknesses. The electric oven includes an automatic ejection function, greatly simplifying mold changes, material clearing, and equipment cleaning and maintenance, thereby improving production-switching efficiency.
Station Two: Pure Negative-Pressure Vacuum Forming (Core Process)
As the core forming station, this machine uses a ductile iron mold platform paired with servo-driven control, achieving a parallelism tolerance of up to 0.03 mm (3丝). The overall machine boasts high precision, strong rigidity, and excellent forming consistency. It employs a pure vacuum negative-pressure forming process without positive-pressure air supplementation, relying solely on vacuum suction to tightly adhere softened sheets to the mold cavity.
This process is particularly suited for standardized products with shallow cavities, medium-deep cavities, no reinforcing ribs, and no undercuts. The forming process is gentle and stable, effectively preventing sheet tearing, localized thickness variations, and other forming defects. Finished products exhibit uniform wall thickness, stable weight, and high yield rates, making them ideal for large-scale standardized production.
Station Three: High-Precision Cutting + Fully Automated Stacking and Discharge
After forming, the parts proceed to the integrated cutting station, which houses a 60–100-ton hydraulic/servo cutting system capable of delivering ample cutting force and producing clean, burr-free cuts. During production, finished products and waste are automatically and precisely separated, with waste automatically collected and stored without manual sorting. A dedicated robotic arm then completes stacking, counting, and orderly discharge of finished products, all without human intervention, enabling fully automated continuous mass production.
Intelligent CNC Control System
The machine is equipped with a high-end CNC control system superior to traditional PLCs, supporting precise manual mold alignment, storage of over 500 production parameters, one-click parameter recall, and efficient, convenient mold changes and debugging. It also features built-in intelligent fault diagnosis and safety interlock protection functions, along with an intuitive, easy-to-understand Chinese-language operating interface that allows beginners to quickly get started while balancing production efficiency and operational safety.
