摘　　要：简要介绍了气辅挤出成型技术,回顾国内外关于气辅挤出技术在数值模拟及试验方面近十年来取得的研究进展,并概述气辅挤出成型的特点在于降低挤出压力降、挤出胀大比及消除或延缓熔体破裂,因此在精密挤出制品中具有广泛的、潜在的应用。The gas-assisted extrusion（GAE） technology is introduced briefly and the investigation of numerical simulation and experimental on GAE at home and abroad is reviewed. At the same time, the characteristic of GAE technology can significantly reduce the pressure drop,die-swell ratio and reduce or eliminate melt fracture, so it has potential applications in manufacturing the precise extrusion product.
