Plastic films (such as PE, PP, PET, PA, PVC) are most sensitive to cooling roller temperature. • PE/PP film cooling roller temperature: 20–40℃ • PET film cooling roller temperature: 10–25℃ • PA (Nylon) film cooling roller temperature: 15–30℃ • PVC film cooling roller temperature: 30–45℃

The fastest cooling speed generally refers to: Cooling rollers with a bidirectional spiral flow channel + thin-walled structure + high thermal conductivity material + mirror finish + low-temperature chilled water medium.

The manufacturing process of industrial cooling roller mainly includes material selection, cylinder forming, internal channel design, surface treatment and precision machining.

The working principle of industrial cooling rollers is mainly to transfer heat from the processed material to the surface of the industrial cooling roller, and further to the internal cooling medium, such as water or coolant. The whole process follows the principles of heat transfer by conduction and convection to maintain the appropriate temperature of the processed material.
