简要地介绍了国外近年来喷射成形工艺方面的进展。随着该工艺的改进及其生产成本的进一步降低，其应用范围将进一步扩大。其中以铝基合金、铁基合金、高温合金及铜合金方面的研究最为活跃。近来喷射成形已逐渐进入了规模化、实用化的生产阶段。 Briefly introduced the foreign injection molding process in recent years progress. With the improvement of the process and the further reduction of the production cost, the application range will be further expanded. One of the most active research in aluminum-based alloys, iron-based alloys, superalloys and copper alloys. Recently, injection molding has gradually entered the large-scale, practical production stage.
