摘　　要：介绍了气体辅助注射成型的工艺过程、特点,气体辅助模设计的基本方法、要求和几种常用控制熔体均衡填充型腔的方法。阐明注射喷嘴进气比模具型腔进气在改善制件的外表面质量及生产效率有更大的优势。利用CAE模拟技术优化气道尺寸和气道布置。The process and characteristic of gas-assisted injection moulding technology were stated. Presentation was also made on basic methods, requirements and some common approaches to con- trol balancing filling of melt in cavities. Researches show that gas-in via injection nozzle is more advantageous than gas-in via cavity in improving the external qualities and production efficiency of products. The dimensions and arrangements of gas passage were also optimized via CAE simulation technology.
