摘　　要：对EVA注射成型中成型工艺参数对制品性能的影响进行研究,结果表明:对于密度,模具温度较为显著,模压时间次之,注射压力与模压压力可忽略不计;对于拉伸强度,注射压力较大,模压压力与模压时间次之,注射压力较小,但各因素影响程度相差不大;对于断裂伸长率,模具温度显著,模压时间与注射压力次之,模压压力较小;对于硬度,模具温度显著,模压时间与注射压力次之,模压压力较小,可忽略不计.The affections of processing parameters on ethylene-vinyl acetate copolymer（EVA）injection forming were studied.It was concluded that the effect of molding temperture on density was the most obvious,while molding time the second,and injection pressure and molding pressure could be omitted.And the affections of factors on the tensile strength were as followed：the difference between all parameters was not so distinct while the injection pressure took the most obvious affection,molding pressure and molding time the second,and injection pressure took little affection.And as to breaking elongation ratio,molding temperature took an obvious affection,molding time and injection pressure the second,molding pressure the least.And as to hardness,molding temperature took a obvious affection,molding time and injection pressure the second,molding pressure took the least and could be omitted.
