Press Release Summary:

May 28, 2010 - Made entirely with engineering grade thermoplastic-glass reinforced polypthalamide, Turbulent Flow Plastic Baffles create turbulence within glycol-based mold coolant, increasing heat transfer and cooling parts evenly and quickly. Baffles can be cut to length with standard shears and are designed to maintain rigidity and other properties at high temperatures over time. Incorporating Turbulent Flow Plastic Baffles into mold's design eliminates stagnant laminar flow.

DME Introduces Turbulent Flow Plastic Baffles

Press release date: May 27, 2010

Innovative design delivers faster cooling performance than traditional brass baffles

Madison Heights, Mich. - DME Company is pleased to introduce its new Turbulent Flow Plastic Baffles for faster mold cooling and reduced cycle times.

The innovative plastic baffle design creates turbulence within the glycol-based mold coolant, increasing heat transfer and cooling parts more evenly and quickly than traditional brass baffles. The Turbulent Flow Plastic Baffles feature a patented, proprietary design that promotes uniform flow of the mold coolant and seals tightly within the mold's cooling channels to ensure quick, 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, they are easier and faster to install. There is no need for secondary procedures associated with cutting and soldering traditional brass baffles.

"The Turbulent Flow Plastic Baffle is an excellent example of our new approach to product development," said Dave Lawrence, President of DME Company. "We complement our engineering talent with the expertise of global partners and inventors to bring the most innovative, problem-solving, products to market more quickly than ever before." Incorporating a Turbulent Flow Plastic Baffle into a mold's design eliminates stagnant laminar flow. Turbulent flow dissipates about three times the BTUs compared to laminar flow. Turbulent Flow Plastic Baffles reduce 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 mold cooling times, frequently approaching 20 percent or better. The feedback and response from customer use of DME Turbulent Flow Plastic Baffles has been overwhelmingly positive, with many customers deciding to change out their brass baffles for this new product to improve performance.
