流延膜用辊筒㊣　

Casting Film Roller

JWELL 制造的流延膜用辊筒采用严格↓的欧洲专业制造标准，经过多道焊接和热处理工艺，保证辊筒的整体结构坚固可√靠。

为了确☉保其高效的热交换效果，流延辊筒的流道均为特殊的螺旋形设计，并对通◥过流道的冷却液流量进行精确的计算，从而尽可能的减小辊筒表面温度误差，提高了产品的温度均匀性。

流延膜用辊筒的动平衡精度▓尤为重要。专用的大型动平衡校验设∩备和多种平衡检测方案，使其在高转速下运行平稳。

JWELL manufactured casting film roller strictly according to European professional manufacturing standards. Several steps of welding and heat treatment process are applied to give ensurance to the overall rigidity and reliability of roller structure.

In order to ensure its efficient heat exchange, casting roller flow channel are designed with the special spiral, and through accurate calculation of the coolant flow, the roller surface temperature deviation are 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, ensures smooth operation at high rotation speed.

较高的生产线速★度要求流延膜用辊筒具ζ有极高的转速、精确的动平衡精度、快速均衡的热交换效率；

High speed of casting film production line means very high rotation speed of the roller, and this requires precise dynamic balancing, high and balanced heat exchange efficiency;
