Description

High-Efficiency Three-Station Thermoforming Solution

The Full-Automatic Positive and Negative Pressure Thermoforming Machine is designed for the high-speed production of plastic food packaging, industrial packaging, cosmetic packaging, trays, lids, containers, and other thermoformed products.

The machine integrates electrical, pneumatic, and mechanical systems into one automated production line. Its three working stations perform forming, cutting, and stacking simultaneously, helping manufacturers increase production capacity while reducing labor costs, material waste, product contamination, and manual handling.

A programmable PLC control system and industrial color touchscreen provide accurate control over the complete production process. Multi-stage infrared heating ensures that the plastic sheet is heated evenly before forming, improving wall-thickness distribution, product clarity, forming precision, and overall product quality.

Both positive and negative pressure forming can be used to manufacture products with detailed shapes, deep cavities, sharp edges, high transparency, and complex designs.

Automatic Production Process

The machine completes the main production stages automatically:

Sheet feeding → Multi-stage heating → Positive/negative pressure forming → Cooling → Cutting → Product stacking → Automatic counting

It can also be integrated with additional processes such as punching, labeling, printing, filling, conveying, and packaging according to the customer’s production requirements.

Key Features

Three-Station Automatic Operation

The forming, cutting, and stacking stations operate simultaneously, providing fast and continuous production with minimal manual handling.

Positive and Negative Pressure Forming

The combined pressure-forming system provides improved product definition, accurate corners, uniform forming, and better surface quality compared with conventional vacuum forming.

PLC and Touchscreen Control

The complete machine is controlled through an industrial PLC and high-definition touchscreen interface, making production parameters easy to set, monitor, save, and adjust.

Multi-Stage Infrared Heating

The tunnel-style infrared heating system provides stable and even sheet heating, helping improve forming quality and reduce unnecessary energy consumption.

High Production Speed

The machine can reach a maximum production speed of 45 cycles per minute, depending on the product design, material, sheet thickness, and mold configuration.

Automatic Stacking and Counting

Finished products are automatically stacked and counted, reducing labor requirements and simplifying connection with downstream conveying and packaging equipment.

Stable and Reliable Operation

The machine is designed for continuous industrial production, offering high forming accuracy, dependable performance, simple operation, and a high degree of automation.

Reduced Material Waste

Accurate sheet feeding, heating, forming, and cutting help improve material utilization and reduce production scrap.
