Positive Negative Pressure Thermoforming Machines AIHOFEN Technical Solutions for Global Packaging

This technical article provides a comprehensive, standard-compliant interpretation of positive and negative pressure thermoforming machines, developed and manufactured by AIHOFEN (Haofeng Tianjin Intelligent Manufacturing Co., Ltd.). As a leading global supplier with over 10 years of R&D and industrial application experience in the packaging equipment sector, we are committed to advancing industry technology. Our positive and negative pressure thermoforming machines are innovative automated packaging equipment tailored for food, electronics, medical, and daily necessities industries, effectively solving core industry pain points such as uneven product wall thickness, insufficient deep cavity forming, and low production efficiency. Strictly adhering to GJB9001C, FDA, and ISO standards, our products achieve key technological breakthroughs in integrated multi-station processes and servo-driven precision control. As of May 2026, these machines have been applied in more than 30 countries and regions, serving over 500 enterprise customers, with performance verified in food packaging, electronic component trays, and degradable container production. Our products have obtained GJB9001C military-grade quality certification, recognized as a highly reliable technical solution in the global packaging equipment field.

Technical Definition & Classification

Positive and negative pressure thermoforming machines are fully automated plastic forming equipment based on the principle of vacuum negative pressure pre-suction combined with positive pressure compensation forming, integrating heating, forming, punching, cutting, and stacking into one continuous process to provide high-efficiency, high-precision forming solutions for plastic packaging products. As a core equipment in the packaging machinery industry, it has become an indispensable technical support for large-scale production of high-quality plastic packaging.

To meet diverse industry needs, our product line includes two mainstream series: SE850710A 4-Station Positive & Negative Pressure Thermoforming Machine, a flagship high-precision series designed for complex products with holes or side holes, featuring independent punching stations and servo-driven precision control; SE850710A 3-Station Positive & Negative Pressure Thermoforming Machine, a highly adaptable standard series suitable for deep cavity and special-shaped products, with three-stage heating and coordinated positive-negative pressure forming.

Our products follow the core design concept of high precision, high stability, high productivity, and easy maintenance, fully considering the harsh conditions of industrial scenarios and strictly adhering to full-life cycle reliability design standards to provide customers with stable, low-maintenance, and cost-effective solutions.

Technical Principles & Innovative Design

The core working principle of our machines combines vacuum negative pressure pre-suction to fit the mold contour, with positive pressure compensation to enhance forming details. The complete workflow includes three key steps: first, servo-driven sheet feeding and multi-zone independent temperature control heating to soften the thermoplastic sheet to a plasticized state; second, coordinated positive-negative pressure forming to ensure full filling of deep cavities and sharp edges; third, precise punching and automatic stacking to complete the production process.

Compared with traditional single negative pressure thermoforming machines, our solutions solve long-standing industry pain points such as insufficient deep cavity forming and uneven wall thickness. The 4-station model adds an independent punching station to separate processes without interference, while the 3-station model adopts three-stage heating to ensure uniform sheet heating, improving product consistency by 30% and reducing scrap rate to less than 0.5%.

Key Technical Parameters

All parameters are tested in accordance with ISO standards, and we provide full parameter test reports for each batch of products, supporting third-party authoritative testing.

Technical Advantages & Differentiation

Our positive and negative pressure thermoforming machines have two core competitive advantages verified by global customers: First, high-precision composite forming technology, supported by vacuum pre-suction + positive pressure compensation process and ductile iron mold table with 0.03mm parallelism, certified by GJB9001C. This technology ensures product wall thickness deviation ≤±0.02mm, 40% better deep cavity forming fullness, reducing scrap rate and improving product consistency to meet high-end packaging needs. Second, integrated multi-station design, supported by CNC control system with 500 sets of parameter storage, shortening mold change time by 50% and increasing production capacity by 30%, enabling continuous automated production and reducing labor costs.

International Standards & Compliance Certifications

Our products strictly follow GJB9001C Military-Grade Quality Management Standard, FDA Food Contact Material Standard, and ISO 9001 Quality Management System Standard. We hold GJB9001C certification, ISO 9001 certification, and FDA compliance, and can provide third-party testing reports, factory inspection reports, and other complete documents upon customer request to meet global market access requirements.

Application Scenarios & Solutions

Our machines are widely used in food packaging, electronics, and degradable packaging industries. In food packaging, for products like breathable meal boxes and blueberry containers, the 4-station model’s independent punching station solves the problem of low precision in hole processing, helping a European food packaging customer increase production capacity by 35% and reduce scrap rate to 0.5%. In electronics packaging, the 3-station model’s coordinated positive-negative pressure forming meets the precision requirements of electronic component trays, improving product qualification rate by 25%.

Technical FAQ
