摘　　要：采用正交试验对聚乙醇酸(PGA)的精密注塑工艺进行优化。考察了注塑压力、注塑速度、背压对精密注塑产品质量的影响趋势和程度,并对试验结果进行了极差分析和方差分析。结果显示背压对注塑产品质量影响最大,其次是注塑速度,最后是注塑压力;注塑参数的最优组合为:注塑压力80 MPa,注塑速度60%,背压60%。The precision injection molding parameters of polyglycolic acid(PGA)was studied by using orthogonal tests in this paper.The influence trend and degree of injection pressure,injection speed and back pressure on the weight of the injection molding products were investigated.The experimental results were analyzed by range analysis and variance analysis.The results show that the most significant factor is back pressure,the second is injection speed and the third is injection pressure.The optimal combination of injection molding parameters is as follows:injection pressure 80 MPa,injection speed 60%,and back pressure 60%.
