Spiral Flow System Casting Roller Matt Surface CPP CPE

Introduction of Casting Roller

The casting roller serves as the primary cooling component within the lamination system, employed to bond materials like LDPE, PP, EVA, EAA, LLDPE, EMA, and EMAA onto BOPP or BOPET films. This casting roller utilizes a jacketed spiral cooling water heat exchange configuration, enabling precise control of the roller surface temperature within a ±1°C range.

This design ensures uniform heat dissipation during the lamination process, critical for maintaining material adhesion and film quality. The spiral cooling structure enhances thermal conductivity by promoting turbulent water flow, which efficiently removes heat generated during the extrusion and bonding of thermoplastic layers.

Characteristics of Casting Roller for Casting Film

Parameter	Specification
Roller diameter	within Φ1600mm
Cylindricity and coaxiality	≤0.005mm
Thickness of the coating	50~80um
Roller surface temperature error	±0.5~1℃
Surface Treatment	matt surface
Running speed	800 meters/min
Overall deformation	<0.05 mm at full load
Dynamic balancing	Q=3.2 during operation

Producing qualified cast films requires adjusting the process on raw materials and mastering the processing conditions, with temperature having significant impact on film performance. The suitable production temperature is 230~250℃.
