Abstract

A variety of parts in microsystems technology are manufactured by injection moulding of polymeric materials. In Particular the high cooling velocity affects negatively the process and the resulting part properties. The scope of this paper is to investigate the influence on the reachable flow length in injection moulding of different polymeric materials. The results indicate that the mould temperature has less impact on the achievable flow length of the polymer melt as the injection pressure. A higher mould temperature leads only to a slight increase in flow length. In addition, a transcending of the glass or the crystallization temperature of polymeric materials with the mould temperature shows no effect on the achievable flow length of the material.

摘要

微系统技术中的各种部件是通过聚合物材料的注塑成型制造的。特别是高冷却速度会对工艺和最终部件性能产生负面影响。本文的范围是研究不同聚合物材料在注塑成型中对可达流动长度的影响。结果表明，模具温度对聚合物熔体可达到的流动长度的影响小于注射压力。较高的模具温度只会导致流动长度略有增加。此外，模具温度超过聚合物材料的玻璃化温度或结晶温度对材料可达到的流动长度没有影响。
