Abstract

Abstract This paper reviews the effects of iron-based powder on shape accuracy of injection moulded parts. Analysed specimens were produced on a micro injection moulding machine. At first, specimens of pure polypropylene (PP) were manufactured. Then specimens containing 1, 2 and 3 vol. % of iron powder additive were produced using the same process parameters. Subsequently, the samples were scanned using scanned using Zeiss METROTOM CT scanner. Results were analysed via CAE inspection tools. The main aim was to compare the shape and flatness of the scanned specimens to the nominal models. Results showed that iron-based additives of this vol.% had no significant effect on shape accuracy of produced parts. This paper is a partial result of the ongoing research focused on effect of iron and steel-based additives on material, magnetic and mechanical properties of polymers.
铁基粉末添加剂对注塑件形状精度的影响
摘要本文综述了铁基粉末对注塑件形状精度的影响。分析样品是在微型注塑机上生产的。首先,制作了纯聚丙烯(PP)试样。然后用相同的工艺参数制备含1、2和3体积%铁粉添加剂的试样。随后,使用蔡司METROTOM CT扫描仪对样品进行扫描。通过CAE检测工具对结果进行分析。主要目的是比较扫描样品的形状和平面度与标称模型。结果表明,该体积%的铁基添加剂对加工零件的形状精度没有显著影响。本文是正在进行的关于铁和钢基添加剂对聚合物材料、磁性和力学性能影响的部分研究成果。
