文摘
- •
A visualization mold is used to study high-pressure foam injection molding process.
- •
The injection speed and gate resistance had no significant effect on cell density.
- •
The injected-gas content and the melt flow index affect bubble nucleation.
- •
The cell growth rate is inversely proportional to cell density in confined volume.
