Double Shell Structure Cooling Roller with Q345 Material and High Heat Transfer Efficiency for Customizable Capacity

The Double Shell Structure Cooling Roller Chrome Coating BOPP is engineered for superior performance in bi-oriented stretch film production, featuring advanced cooling technology with chrome-coated surfaces for enhanced durability and heat transfer efficiency.

Modern cooling rollers in bi-oriented stretch film production utilize two primary internal configurations:

• Double-Layer Single-Flow: Features outer shell, inner shell, and spiral baffle design. The working medium (water/thermal oil) enters through a single-flow heat transfer channel for effective heat dissipation.
• Double-Layer Double-Flow: Incorporates dual-path heat transfer channels for higher efficiency, though with more complex manufacturing requirements and higher cost.

Ideal for various industrial applications including:

• Sheet, plate, and compound machines
• Printing and plastic packaging machinery
• Processing of materials including film, aluminum foil, glass, cloth, and decorative materials
• Compatible with PVC, ABS, PP, PE, PT, PC plastics and various surface treatments
