Product Specification

Matt Surace Casting Roller  EVA Film Lamination 

Introduction of Casting Roller:

Casting Roller is the main cooling roller of the Lamination System, which is used to Laminate LDPE,PP,EVA,EAA,LLDPE,EMA,EMAA on BOPP  or BOPET film, Generally  the casting roller adopt jacket spiral cooling water heat exchange structure, it can control the roller surface temperature even .

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.
