D-M-E Company (Madison Heights, MI) has introduced its new Turbulent Flow Plastic Baffles for faster mold cooling and reduced cycle times. The innovative plastic baffle design creates turbulence within the cooling liquid—typically water or oil—serving to increase heat transfer and cool parts more quickly than traditional baffles. The turbulent flow plastic baffles feature a proprietary design that promotes uniform flow of cooling liquid and seals tightly within the mold’s cooling channels to ensure uniform cooling. Made entirely with an engineering grade, thermoplastic-glass reinforced polypthalamide, Turbulent Flow Plastic Baffles perform extremely well even in high heat production environments and maintain their rigidity and other physical and mechanical properties at high temperatures over time. They are less expensive than brass baffles and because they can be cut to length with standard shears, there is no need for secondary procedures associated with cutting and soldering traditional brass baffles. Incorporating a Turbulent Flow Plastic Baffle into a mold’s design nearly eliminates stagnant laminar flow cooling as turbulent flow dissipates about three times the BTUs compared to laminar flow. This cooling method reduces “hot core” syndrome, lowers the ?T across the mold surface and increases coolant wall velocity. Better cooling at the hot-spots in a mold can result in significant improvements in overall cycle times, sometimes approaching 20 percent or better. The feedback and response from beta testing of D-M-E’s Turbulent Flow Baffle has been overwhelmingly positive.
