Classification by Pressurization Method
Vacuum (Negative Pressure) Thermoforming Machine: Relies on negative pressure generated by a vacuum to conform the softened sheet to the mold; this is the most widely used standard model.
Positive Pressure Thermoforming Machine: Uses an air compressor to apply pressure to the front side of the sheet for forming; offers higher precision and is suitable for products requiring fine detail, such as medical devices.
Positive and Negative Pressure Thermoforming Machine: Combines both pressurization and vacuum suction; creates a greater pressure differential, resulting in superior forming precision and detail reproduction.
Classification by Sheet Thickness
Thin-Sheet Thermoforming Machine: Processes sheets 1–2 mm thick (or thinner); commonly used for small packaging products like toy and electronics packaging.
Thick-Sheet Thermoforming Machine: Processes sheets 1–10 mm thick; used for large items such as appliance liners, luggage, and display stand components.
Classification by Automation Level
Semi-Automatic Thermoforming Machine: Features a simple structure with switchable manual and automatic modes; suitable for small-batch production or prototyping.
Fully Automatic Thermoforming Machine: Continuously and automatically performs feeding, heating, forming, and cooling; offers high efficiency and is ideal for large-scale, continuous production.
