这段话是有关铸模工艺的,求准确的.Standard reciprocating screw injection molding machines with a high compression screw (minimum 3:1 and preferably 4:1) and low back pressure (0.36 Mpa/50 PSI) are favored. Using a low compression screw (I.E. general purpose 2:1 compression ratio) can resul这段话是有关铸模工艺的,求准确的.Standard reciprocating screw injection molding machines with a high compression screw (minimum 3:1 and preferably 4:1) and low back pressure (0.36 Mpa/50 PSI) are favored. Using a low compression screw (I.E. general purpose 2:1 compression ratio) can result in unmelted particles and poor melt homogeneity. Using a high back pressure to make up for a low compression ratio may lead to excessive shear heating and deterioration of the Celcon material.
回答：配备一个高压锁紧螺钉（最小值3:1，首选值4:1)且低反压力(0.36 Mpa/50 PSI)的标准的往复式注坯模型机器为有利。采用低压缩螺旋(即通用压缩比2:1)可导致融性差和产生不熔粒子。使用高反压力补偿低压缩比可能会导致过分的剪切热和聚甲撑氧材料的恶化。
