Casting Film Roller

Suzhou Jwell Precision Machinery Co.,LTD located in the Chengxiang Industrial 

Park,Suzhou city Jiangsu province,is a professional company for making screw and barrel, roller and  other large size of high precision components.

We have many sets of CNC machines, heavy duty processing machines and complete heat treating line. We use the modern manufacturing techniques and strict quality management  system, and we extend the quality controlling to R&D and pre-sale and after-sale service  to ensure the high quality of  machinery and service.      

we will always help our customers and partners to create more value by our technology, quality, service advantages.

Our ability in roller making:

Suzhou Jwell Precision Machinery Co.,Ltd would like to share our many years’ rich experi-ence in the roller and surface refine area.Our products are widely used in plastic sheet and film processing, non-woven fabric, leather processing, paper making, printing,thin steel manufac-turingetc. We are trying our best to reach the highest performance index for the geometry dimensions,roundness,roughness of the surface and the using life.

● Max. diameter and length of the roller：Φ1600×14000mm

● Max. weight of the roller：15000kg

● Roundness and coaxiality：≤ 0.01mm

● Roughness of the surface：Ra 0.005～0.01μm

Casting Film Roller:

JWELL manufactured casting film roller strictly according to European professional manufac-turing 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 tempera-ture 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.

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;
