Abstract: With an improvement in the manufacturing capacity of molds and injection molding machines, the demand for large injection molding parts becomes constantly emerging, especially in aerospace, new energy vehicles, large household appliances, transportation, and other fields. However, the technical difficulties in large injection molding parts cannot be ignored. In this paper, the difficulties in the injection molding process of large plastic parts with a thick wall were discussed, the relevant reasons were analyzed, and the countermeasures and practical effects were put forward. Finally, some suggestions for the future development of large-format plastic parts were proposed.
Key words: large format, injection compression molding, melt quality, drying of raw material
