Technical Principles

The core working principle of AIHOFEN positive and negative pressure thermoforming machines is based on the plasticization and forming of thermoplastic sheets, combining negative pressure pre-forming and positive pressure supplement to achieve precise product shaping .

Complete Working Process: 1. Servo sheet feeding + multi-stage independent temperature control heating: Sheets are evenly plasticized to the required temperature ; 2. Negative pressure pre-forming: Sheets are adsorbed to fit the mold contour under vacuum ; 3. Positive pressure supplement forming: High-pressure air is injected to fill deep cavities and details, ensuring full product shaping ; 4. Precise punching + automatic stacking: Finished products are cut and stacked automatically for direct connection to packaging lines .

Core Architectural Innovations: Multi-stage Temperature Control Heating Module: Equipped with Japanese Yamatake temperature controllers and imported heating tiles, each zone is independently controlled to adapt to different sheet materials and reduce downtime for mold changes ; Positive-Negative Pressure Forming Module: Ductile iron mold table driven by servo motors with parallelism of 0.03mm, ensuring stable and precise forming ; Intelligent CNC Control System: Superior to conventional PLC systems, supporting storage of 500+ process parameters and one-click recall, with fault self-diagnosis and remote monitoring functions .

Comparison with Traditional Solutions: Compared to traditional single negative pressure machines, our technology solves the problems of incomplete deep cavity forming and uneven wall thickness, improving product qualification rate by over 15% and increasing production capacity by 30%-50% .
