D-M-E (Madison Heights, MI) offers its new Eco-Smart Hot Runner System optimized specifically for the processing of bio-resins. Injection molding grade PLA and other bio-resins are "green" materials with applications that mirror those of GPPS (General Purpose Poly Styrene) with some characteristics of PET (Polyethylene Terephthalate). Injection molding of many bio-resins places unique constraints on both tooling and processing. The material is hyper-sensitive to temperature and degrades readily into highly corrosive acids. In normal operation, bio-resins tend to plate out these acids onto the walls of the molding system. Eco-Smart features corrosion-resistant components and addresses the low pressure requirements and cooling issues that bio-resin users face. It promises an uninterrupted material flow path for reduced sheer and a thermal isolation component design for reduced sheer. Eco-Smart Hot Runner Systems incorporate D-M-E's global manifold and components standards to ensure that it provides operational excellence anywhere in the world. The market for renewable/industrially compostable resins is continuously growing. D-M-E is qualifying additional polymers for use with the Eco-Smart as they become available. www.dme.net
