The hierarchical structure of water-assisted injection molded HDPE: SAXS study
关键字：water-assisted injection molding; lamellar;
molding
(CIM) was also characterized. The result shows that
the WAIM part exhibits a distinct skin-core-water channel
structure which is different from the skin-core structure
for the CIM part. In the skin layer of both WAIM and
CIM parts, the shish-kebab structure was formed due to
the shear stress brought by melt filling, but the lamellar
orientation parameter of CIM part is smaller than ...

Numerical simulation and experimental verification of the filling stage in injection molding
关键字：finte element,injection molding,ALE method
The linear low-density polyethylene melt is described by the modified Cross model, the dependence of melt viscosity on temperature incorporated with the Arrhenius
equation, and the Moldflow second-order model in this investigation. The mass, momentum conservation, and constitutive equations are discretized and solved by using the iterative stabilized fractional step algorithm along with the Crank...

A fast approach to the bem-based cooling analysis of injection mold
关键字： injection molding, cooling simulation, approximated sparsification method
Mold cooling system design in injection molding is critical from the viewpoint of productivity and quality of molded parts. Most of the mold cooling simulations are based on the boundary element (BEM). In this paper, a f...

Numerical simulation investigating core deflection in injection molding
关键字： Core deflection, core deflectability, thin-walled injection molding
In the manufacturing of long hollow plastic parts with closed ends, like test tubes, unevenly advancing melt front around the cores results in core deflection, which becomes a pervasive problem especially when the parts are t...
