Based on the analyses of wall slip mechanism of polymer melt flowing, the effects of wall slip on melt filling flow behavior in micro injection molding were investigated.
分析了微尺度下熔体壁面滑移机理，研究了微注塑成形中壁面滑移对熔体充模流动行为的影响。
The quoted MFR value is the weight of polymer melt flowing through an orifice in specified conditions, so the higher the MFR value, the lower the melt viscosity and the easier the material will flow.
MF R采用的数值是在一定的条件下通过口模的聚合物熔体的重量，所以MF R越大，熔体粘度越低，而材料的流动性就越好。
To control the melt flowing and foaming of polymer are the key factors to ensure the quality of products during the extrusion moulding of the integral door leaf of low foamed rigid PVC.
