Huarong's Microcellular Foam Injection Molding Machine has received the 2027 Taiwan Excellence Award, recognizing its innovative approach to improving dimensional stability, reducing material consumption, and enhancing injection molding efficiency.
The machine integrates a supercritical fluid (SCF) injection system, a specialized plasticizing unit, a shut-off nozzle, and precise injection control technology. By introducing nitrogen (N₂) or carbon dioxide (CO₂) into the polymer melt, the process creates fine, uniformly distributed microcells that help reduce shrinkage, warpage, and sink marks commonly associated with conventional injection molding.
Depending on part geometry, resin properties, and mold conditions, microcellular foam molding can achieve approximately 15% to 20% part weight reduction, 10% to 20% material savings, and a 30% to 50% reduction in required clamping force. In selected applications, holding pressure requirements can also be reduced or eliminated, potentially improving production efficiency.
Featuring Huarong's patented physical foaming injection system (Taiwan Utility Model Patent No. M659181), the machine can also support selected post-consumer recycled (PCR) material applications, subject to material validation. It is suitable for automotive components, consumer electronics, sporting goods, and industrial plastic parts, helping manufacturers improve product consistency while pursuing lightweighting and material efficiency.
Actual performance depends on material properties, part design, mold construction, and processing conditions.
