Engineered for high-speed polyfilm production lines, Huatao Group High-Precision Double-Shell Duo-Flow Chill Roll is the ultimate solution for rapid polymer solidification. Utilizing cutting-edge internal fluid dynamics and special temperature-equalization technology, this chill roller ensures instantaneous and uniform heat transfer across the entire working area. By maintaining a highly consistent surface temperature with a variation of within ±0.5°C, it effectively prevents local supercooling and surface condensation. Crafted from premium alloy or stainless steel, the roller features a heavy-duty chrome plating layer (≥120μm) with an exceptional surface hardness exceeding HRC 62 and an ultra-fine mirror finish of Ra≤0.005μm. It is designed to minimize film defects, optimize polymer crystallinity, and significantly boost the overall yield and surface optical quality of your biaxially oriented and cast film products.
