Chill Transfer Rollers
Chill transfer rollers are specialized cooling rollers used to cool, shape and stably transfer materials such as plastic film, sheet and coated products during production. With internal fluid circulation structure, they provide efficient and even heat exchange to ensure stable material forming and quality. Made of high-quality stainless steel with precision finishing, they feature excellent thermal conductivity, wear resistance and smooth operation. Widely used in plastic extrusion, laminating, coating and film making equipment, with customizable size, flow design and surface treatment available.
What you may want to know about Chill Transfer Rollers
As a professional high‑precision industrial roller manufacturer, AstraRoll specializes in custom‑engineered chill transfer rollers and precision cooling rollers, critical temperature‑control components for film casting, flexible packaging, extrusion coating, converting, calendaring, printing and plastic processing industries. Our chill rollers integrate internal cooling circulation systems with high‑precision external surface treatment, rapidly cooling, setting and transferring web‑form materials such as BOPP, PET, PE films, plastic sheets and composite substrates. They ensure stable surface flatness, uniform cooling temperature and high‑speed continuous production quality for high‑end packaging and polymer processing lines.
Unlike ordinary conveying rollers, precision chill rollers require strict temperature uniformity, high‑precision surface finish, thermal stability and reliable internal water‑cooling sealing performance. We adopt high‑strength seamless steel tubes, alloy steel and stainless steel roller shells, with internal spiral‑channel or drilled‑hole cooling structures for efficient heat exchange. External surface treatments include hard chrome plating, super‑mirror polishing, nickel plating and anti‑corrosion coatings. We precisely control roundness, straightness, concentricity, surface roughness and cooling‑water circulation efficiency, supporting fully customized roller size, cooling structure, surface finish and working temperature range.

Key Features & Product Advantages
Efficient Internal Cooling & Uniform Temperature Distribution
Optimized spiral‑channel cooling structure ensures rapid heat exchange and consistent surface temperature, avoiding material warping, wrinkling and uneven thickness during cooling.
Ultra‑Smooth Mirror‑Grade Surface Precision
Super‑polished chrome‑plated finish delivers high‑gloss surface transfer, scratch‑free performance and stable web tension, improving finished‑product flatness and transparency.
High Thermal Stability & Deformation Resistance
High‑strength thick‑wall roller shell design resists thermal expansion and high‑speed rotation‑induced deformation, maintaining long‑term dimensional stability.
Excellent Wear & Corrosion Resistance
Hard chrome, nickel or stainless steel surfaces resist abrasion, ink/solvent corrosion and water‑scale erosion, extending service life in continuous industrial cooling production.
Reliable Sealing & Leak‑Proof Structure
High‑precision shaft‑end sealing components prevent cooling‑water leakage, ensuring safe and stable operation in 24‑hour continuous production environments.
Full Customization for Cooling Processes
Customize roller dimensions, cooling channel design, surface roughness, working temperature range and surface coating to match film extrusion, coating, printing and calendaring requirements.
