Implicit Control-Volume Method for Injection Molding Simulation of Quadrilateral and Triangular Mixed Mesh
关键字： Injection molding, control-volume method, mixed mesh, mid-plane, PCG
Implicit control-volume method based on quadrilateral and triangular mixed mesh was proposed for injection molding simulation with Hele-Shaw approximation. Since control-volume method will generate asymmetric matrix for quadrilateral mesh, the asymme...

A Visualization Method to Investigate the Mechanism of Cell Nucleation and Growth in High-Pressure Foam Injection Molding
Introduction
Foam injection molding (FIM) is one of the most promising technologies owing to its ability to
produce low-density parts with high geometrical accuracy and stiffness-to-weight ratio at fast
production cycles [i]. In this technology, a gas-charged melt is being injected into a confined cavity.In low-pressure FIM, i.e. short shot injection, foaming occurs due to the pressure drop ov...
