Water Cooling Steel Embossed Chill Roller

This Water Cooling Steel Embossed Chill Roller is designed for film casting, sheet extrusion and lamination lines requiring precise temperature control at the embossing or polishing nip. The roller shell is manufactured from 45# seamless steel pipe or alloy steel and undergoes complete heat treatment to maintain geometry when chilled water flows through at production speeds. An internal double wall spiral flow channel guides cooling water in a continuous spiral path, ensuring uniform heat removal across the entire working surface and preventing hot spots and temperature variations that cause film sticking, surface gloss inconsistencies, and uneven embossing depth.

Key Features

Internal spiral cooling channel: Double wall spiral flow removes heat evenly and maintains uniform surface temperature across the roller width
Even temperature profile: Consistent chilling prevents film sticking, gloss bands, and uneven embossing depth on wide webs
Multiple face options: Mirror polished, matte, or engraved embossing faces tailored to film grade and finish requirements
Heat treated steel shell: 45# seamless pipe or alloy steel is tempered and quenched for stable geometry and extended service life
Chrome plating option: Hard chrome face resists wear and corrosion while simplifying chill surface cleaning
Dynamic balancing: Each roller is balanced for smooth operation at production speeds, protecting bearings and drive components
Custom journal and rotary joint: Shaft ends and water connections designed to match your extruder, casting unit, or laminator layout

Applications

This chill embossing roller is suitable for film casting lines processing CPP, BOPP precursor sheet, and PET film; sheet extrusion lines for PVC and polycarbonate; and lamination lines where a chilled steel roller sets the surface finish of composite webs. It also serves textile coating and non-woven calender lines requiring temperature-controlled rollers at finishing stations. The combination of spiral water cooling and precision-machined faces makes it ideal for optical film polishing, embossed film texturing, and release paper casting, where uniform temperature is critical for first-grade output. For processes with hot films prone to sticking, chrome-plated faces with fine release finishes can be specified alongside internal cooling circuits, providing integrated temperature and surface quality control.

Packaging & Quality Assurance

Each chill roller undergoes flushing, drying, and anti-rust protection before the face is film-wrapped and the roller is secured in a wooden crate with protective end caps. Rotary joints and accessories are packed separately in export-grade cartons. Inspection includes shell material certificates, heat treatment records, hardness testing, cooling channel pressure testing, dimensional checks, and dynamic balancing reports. Our manufacturing facility operates under an ISO 9001 quality system with comprehensive inspection equipment, supported by engineers with over 25 years of roller design experience for film and sheet processes. Please provide your working width, roller diameter, cooling water capacity, and film grade to confirm channel design and delivery schedule for your production line.
