JWELL manufactured casting film roller strictly according to European professional manufacturing standards. Several steps of the welding and heat treatment process are applied to give insurance to the overall rigidity and reliability of the roller structure.
In order to ensure its efficient heat exchange, casting roller flow channels are designed with the special spiral, and through accurate calculation of the coolant flow, the roller surface temperature deviation is reduced to the least possible. It improves the temperature uniformity of the product.
The most important is the precision of dynamic balancing of roller. Specialized large dynamic balance calibration equipment and a variety of balance detection scheme, ensure smooth operation at a high rotation speed.
High speed of casting film production line means very high rotation speed of the roller, and this requires precisedynamic balancing, high and balanced heat exchange efficiency;
Features:
Roller diameter: max. 1600 mm
Roller cylindricity, concentricity both <0.005mm;
Roller surface hard chromium plated, coating thickness is 50 - 80 um
Roller surface temperature deviation 0.5-1C;
roller surface treatment: miror polished, super finishing miror, matt, mist and anti adhesive surface:
Speed: max.800 m/min;
Overall deformation: < 0.05 mm at full load
Best dynamic balance: Q = 3.2
In summary, casting film rollers are crucial for producing high-quality plastic films with consistent properties.
