项目摘要

Within the research project " Verarbeitungsbelastung und werkstoffliche Gebrauchstauglichkeit von spritzgegossenen Mikroelementen" of the DFG Research Group 702 "Maschinen-, Werkzeug- und Prozessentwicklung für neue Verfahren zur Herstellung von Mikrobauteilen über flüssige Phasen" the basic influence of the process conditions on the resulting properties of thermoplastic micro parts could be identified. In particular, different cooling conditions using thermal low conductive mould materials favour the morphology and thus the resulting properties in use. Due to the high wear and the limited controllability of the cooling conditions the application of these materials is limited.The aim of the project is to use the fundamental knowledge about influences on the material be-haviour to investigate the defined local morphology development in injection moulded parts. By means of novel in the mould integrated segmented tempering elements (high performance heating ceramics) the cooling of the material is locally influenced so that either a maximum gradation of part properties or a homogenization of process or geometry-related influences is achieved. Furthermore, interdependencies with regard to the achievable aspect ratio and fill-dependent replication of defined structures are researched in the project.From the knowledge gained in the project to local influence of part properties an algorithmic model should be developed to enable an abstraction of locally expected part properties, using material and process-related input parameters. The knowledge on influencing values, interdependencies and local effects on part properties are transferred into demonstrator part. Furthermore, based on the research results guidelines for mould and process design for manufacturing of micro-components under dynamic mould tempering will be derived.

在研究项目中，在DFG研究组702“ Maschinen-，werkzeug- und prozessentwicklung之间的行为与Werkstoffliche之间的Vera”中，过程条件对产生的塑性微零件的基本影响，可以通过热量材料来识别出较低的冷却条件。冷却条件的有限的可控性限制了这些材料的应用。该项目的目的是利用对材料的影响的基本知识来调查注射模型零件中定义的局部形态开发，这是通过霉菌综合段的发冷元素（高性能加热陶瓷）的最大范围或一部分的冷却型的零件。有影响。此外，在项目中研究了有关可实现的纵横比和填充依赖性复制的相互依存关系。从项目中获得的知识到零件属性的局部影响，应开发算法模型，以实现材料和流程的输入参数来启用局部预期的零件的抽象。对影响价值，相互依赖性和对零件属性的局部影响的知识被转移到演示者部分。此外，将基于在动态模具回火下制造微型组件的霉菌和过程设计的研究结果指南。
