消除注塑聚合物零件中的翘曲是当今注塑行业中最重要的问题之一。 这种情况在几何形状中非常严重,由于其几何特征而特别容易受到翘曲的影响,并且由于厚度变化高,具有长而纤细的拓扑结构。 这些特征在这些特殊的几何形状中,不可能用传统技术制造,以满足行业的尺寸和可持续要求。 本文介绍了一种创新的绿色构象冷却系统,该系统专为高度易受翘曲的细长几何形状的部件设计。 此外,作者介绍的工作调查了使用钢合金制成的高导电刀片与使用增材制造的构象通道相结合的重要性,以减少在复杂制造长而纤细部件中具有影响力的参数,如翘曲,冷却时间和残余应力。 本真实工业案例研究的结果表明,使用构象冷却布局使循环时间缩短了175.1 s 66
Eliminating warpage in injection molded polymeric parts is one of the most important problems in the injection molding industry today. This situation is critical in geometries that are particularly susceptible to warping due to their geometric features, and this occurs with topologies of great length and slenderness with high changes in thickness. These features are, in these special geometries, impossible to manufacture with traditional technologies to meet the dimensional and sustainable requi...
