Structure and Properties of Injection Molded, Thermoplastic Micro Parts
For the utilization of thermoplastic injection moulded parts in technical or precision applications, optimal properties by processing accordingly to the material and the part are desirable. The interrelations between the processing conditional morphology and the resulting properties from macro to micro parts of semicrystalline thermoplastics were pursued in this work. Thereby the influence of decreasing part dimensions, of the injection moulding material as well as of the processing parameters was researched. For optimization of the part properties the effect of the thermal conductivity of the mould material was observed.
Attributable on increasing cooling and shear rates with decreasing part dimensions distinctly changed morphologies and mechanical data occur. However, by selection of a material with a high rate and ability to crystallize the interference can be significantly reduced. Overall, the processing parameters can be ascribed hardly any influence. By utilization of thermal low conductive mould materials the development of part properties are significantly favoured.Lesen Sie die deutsche Zusammenfassung auf Kunststoffe.de
