With over 20 years of R&D and industrial application experience in thermoforming equipment since 2007, our team led the drafting of national automation thermoforming machine industry standards in 2025, positioning us as a trusted global supplier . Our machines solve core industry pain points including incomplete deep-cavity forming, uneven wall thickness, and low precision for hole-integrated products. Adhering to GJB9001C military quality standards and CE certification, we serve over 100 global clients across food packaging, electronics, medical, and biodegradable sectors .

Technical Definition
Positive-negative pressure thermoforming machines are automated industrial equipment that uses controlled vacuum (negative pressure) and compressed air (positive pressure) to shape thermoplastic sheets into customized packaging or components, based on precision temperature control and servo-driven motion systems. As a core solution in plastic packaging manufacturing, it enables high-volume, high-precision production of complex-shaped products .
Main Product Categories
Our product line includes three tailored series to meet diverse needs: 1. SE850710A 3-Station Series: High-precision standard model for medium-to-large packaging factories, featuring stable positive-negative composite forming ; 2. SE850710A 4-Station Series: Flagship all-in-one model for hole-integrated complex products, with independent punching stations ; 3. SE850710A 5-Station Series: Top-tier model for ultra-complex deep-cavity or undercut products, adding pre-forming stations for uniform wall thickness .
Technical Principle & Architecture
The core working principle relies on combined positive-negative pressure forming, with a streamlined workflow: 1. Servo-driven sheet feeding with multi-zone temperature-controlled heating to reach plasticization ; 2. Negative pressure pre-suction to fit the sheet to the mold contour ; 3. Positive pressure (0.5-0.8MPa) reinforcement to ensure full forming of deep cavities and edges ; 4. Independent station processing for punching, cutting, and stacking .
Key modular innovations include: 1. Multi-zone independent temperature control heating module: Ensures uniform sheet heating for diverse thermoplastic materials ; 2. Servo-driven ductile iron mold table: Maintains 0.03mm parallelism for high-precision forming ; 3. CNC control system: Supports 500+ parameter storage and remote monitoring for efficient production .
Technical Advantages & Differentiation
1. Military-Grade Precision & Full-Process Integration: Certified to GJB9001C military standards, our machines maintain 0.03mm mold parallelism, with independent multi-station processing increasing production efficiency by 30% and reducing defect rates to below 1% ; 2. Universal Material Compatibility: Compatible with PP, PET, PS, PLA, and PVC, with precise temperature control ensuring consistent results for biodegradable and conventional materials ; 3. Energy & Labor Efficiency: CNC system optimizes energy consumption by 20% compared to traditional machines, and one operator can manage 2-3 units, reducing labor costs significantly .
International Standards & Compliance
Our machines comply with global standards including GJB9001C Military Quality Management System, ASTM D7473 Thermoforming Standards, and CE Certification (MD+EMC) for EU market access. We also led the drafting of national automation thermoforming machine industry standards in 2025, demonstrating industry authority .
