Description
Fully Automatic Four-Station Thermoforming Production Line
The Full Automatic Positive and Negative pressure Thermoforming Machine (4 Station) is designed for high-speed and high-precision production of plastic packaging products.
The machine combines mechanical, electrical, and pneumatic systems in one automated production line. Its multi-station configuration allows heating, forming, punching, cutting, stacking, and counting operations to be completed continuously, significantly improving production efficiency while reducing manual handling and labor costs.
Positive and negative pressure forming technology provides strong forming capability, accurate product details, clear edges, uniform wall thickness, and excellent surface quality. It is particularly suitable for producing transparent, deep-draw, shallow-draw, square, round, flanged, irregular, and complex-shaped products.
Automated Production Process
The machine can complete the following production stages automatically:
Sheet feeding → Multi-stage heating → Positive and negative pressure forming → Cooling → Punching → Cutting → Stacking → Automatic counting
Optional functions such as labeling, printing, filling, conveying, and automatic packaging can also be integrated according to the customer’s production requirements.
Key Features
Four-Station Integrated Production
The machine combines multiple production processes into one continuous line, reducing secondary handling and increasing overall productivity.
Positive and Negative Pressure Forming
The dual-pressure forming system provides better mold reproduction, sharper product details, accurate corners, and improved surface quality compared with standard vacuum-forming equipment.
Automatic Punching and Cutting
The integrated punching and cutting stations provide accurate holes, clean product edges, consistent dimensions, and efficient separation of finished products.
PLC and Touchscreen Control
The complete production line is controlled by an industrial programmable logic controller and color touchscreen. Operators can conveniently set, monitor, and adjust production parameters through the human-machine interface.
Multi-Stage Infrared Heating
The tunnel-style infrared heating system heats the plastic sheet evenly, helping improve material distribution, product consistency, and forming quality.
High-Speed Production
The machine can achieve a maximum forming speed of 45 cycles per minute, depending on the product design, plastic material, sheet thickness, and mold configuration.
Automatic Stacking and Counting
Finished products are automatically collected, stacked, and counted, reducing manual work and making it easier to connect the machine with conveying or packaging systems.
Reduced Contamination
The continuous automatic process reduces direct manual contact with finished products, making the machine suitable for food, medical, cosmetic, and hygiene-sensitive packaging applications.
Stable Industrial Performance
The machine is designed for reliable continuous operation, with accurate motion control, convenient operation, strong functionality, and a high degree of automation.
