流延膜用輥筒

Casting Film Roller

JWELL 制造的流延膜用輥筒采用嚴格的歐洲專業制造標準，經過多道焊接和熱處理工藝，保證輥筒的整體結構堅固可靠。

為了確保其高效的熱交換效果，流延輥筒的流道均為特殊的螺旋形設計，并對通過流道的冷卻液流量進行精確的計算，從而盡可能的減小輥筒表面溫度誤差，提高了產品的溫度均勻性。

流延膜用輥筒的動平衡精度尤為重要。專用的大型動平衡校驗設備和多種平衡檢測方案，使其在高轉速下運行平穩。

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.

較高的生產線速度要求流延膜用輥筒具有極高的轉速、精確的動平衡精度、快速均衡的熱交換效率；

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;
