摘　　要：采用电磁动态注射机注塑成型LDPE试样,并对其进行拉伸强度、DSC和X射线衍射测试来探讨振动频率和振幅对制品结构性能的影响。结果表明,施加振动后,拉伸强度提高,熔点向高温漂移,晶粒尺寸变小,完善程度提高,但晶型未发生明显的改变。Electromagnetic dynamic plastics injection molding machine was adopted to mold LDPE samples, and these samples were tested on tensile strength, DSC and X Diffraction to explore the influence of vibration frequency and amplitude on the structure performance of products. The results show that the tensile strength can be enhanced, the melting point has moved to higher temperature, and the dimension of crystal grain has decreased which improve the perfection of crystal, but there is no obvious change in crystal shape.
