DuPont reveals new technology for greater production efficiency
New, In-Mold Hold Pressure (IMHP) technology from DuPont targets efficiency improvements during the molding process by decreasing the overall cycle time. The concept behind this objective is to apply hold pressure in the mould during the dosing process. According to DuPont research at its European Technical Center in Meyrin, Switzerland, the new technology can lead to a reduction in cycle time by up to 30 percent versus a standard molding cycle while maintaining optimum mechanical and dimensional properties. IMHP technology can only be adopted for semi-crystalline polymers, that require constant holding pressure profiles, and is most effective in the production of thick-walled, high volume parts that use more than 50 percent of screw volume.
