Fog Surface Treatment Casting Roller with Φ1600mm Diameter and ≤0.005mm Cylindricity for Precision Film Cooling

Fog Surface Treatment Casting Roller Casting PP Film

Introduction of Casting Roller:

The casting roller adopts strict European manufacturing standards and undergoes multiple welding and heat treatment processes to ensure that the overall structure of the roller is strong and reliable. In order to ensure its efficient heat exchange effect, the flow channels of the casting roller are all specially designed in a spiral shape, and the coolant flow rate through the flow channels is calculated to minimize the roller surface temperature error and improve improve the temperature uniformity of the product. The dynamic balancing accuracy of rollers used for cast films is particularly important. Dedicated large-scale dynamic balance calibration equipment and multiple balance detection solutions enable it to run smoothly at high speeds.

Characteristics of Casting Roller for Casting Film:

Producing qualified cast films not only requires adjusting the process on raw materials, but also mastering the processing conditions, among which temperature has a greater impact on film performance. ‌The suitable production temperature is 230~250℃. ‌The air knife on the Cooling Roller must be adjusted appropriately to keep the film cooled evenly and to avoid unstable thickness or failure to adhere to the roller, which may cause wrinkles or affect the appearance quality. ‌In addition,‌the key points of the cast film production process include the design of the T-shaped machine head, the surface finishing of the cooling roller, and the monitoring of the film thickness through beta-ray or infrared thickness gauges to achieve satisfactory thickness requirements.

Material: Select high-quality 45# steel pipe, alloy steel pipe, precision steel pipe, etc.

Structure: Various structural designs such as inner tank spiral flow channel and jacket type

Processing: Advanced heat treatment process, quenching and tempering, after turning, assembly and other processing, the red sleeve is hot-fitted and welded to remove the application.

Strength, quenching, fine turning, fine grinding and plating, hard chrome, super fine grinding, precision grinding using American 3M abrasives Polished or sanded to matte finish.
