RISDevelopment of Advanced Hybrid Polymer Melt Delivery Systems for Efficient High Precision Injection Molding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel melt manipulation “RheoDrop” concept for hot runner injection molding is presented. In this concept, a controlled rotational shear is applied to a polymer melt in the hot drop to reduce its viscosity without raising ...
Effect of Micro Injection Molding Processing Conditions on the Replication and Consistency of a Dense Network of High Aspect Ratio Microstructures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When molding macroscale polymer parts with a high density of microfeatures (>1 أ— 106/cm2), a concern that presents itself is the ability to achieve uniform replication across the entire domain. In the given study, ...
