The role of vacuum technology in the thermoforming process

Inline thermoformers require several precisely controlled vacuum levels:

 

Pumps

 

Thermoforming vacuum (vacuum forming)

shapes the bottom film cleanly into the mold – depends on film thickness, material, and temperature

Pumps for process vacuum

 

Process vacuum for evacuation

determines the residual oxygen values – particularly critical for meat, cheese, and MAP

Support and control pressure zones inline thermoformer

 

Control and support pressure zones

enable fast, repetitive movements – important for high cycle rates in inline operation

 

To ensure that these processes run smoothly, the thermoformer needs a vacuum solution that responds quickly, remains pressure-stable, operates energy-efficiently and at the same time withstands the challenging conditions of food production, such as moisture, cleaning processes and temperature differences.
