在传统的注射成型工艺中,与宏观零件相比,高流动和冷却速度会影响微观零件的形态和摩擦学性能。一种具有动态co2回火的新型模具技术的目标是增强对凝固阶段的温度-时间形态行为的理解,这从根本上主导了结构的形成。本文的范围是提供对加工温度的影响的理解,在这种情况下,模具温度,对注射成型的微观部件的形态和摩擦学性能。此外,在优化测试方法方面,应确定微零件摩擦学测试条件的特征。结果表明,微零件的摩擦学性能主要受近层皮肤性质的影响,通过使用接近结晶温度的模具温度可以大大改善微零件的摩擦学性能。此外,摩擦学测试方法适用于磨合和固定阶段的正确和高解决方案,以确定蒙皮层对磨损行为的影响。
In conventional injection-moulding processes high flow and cooling velocities affect the morphological and tribological properties of microparts when compared to macroscopic parts. A novel mould technology with dynamic CO2-tempering is targeted with an enhanced understanding of the temperature time behaviour of morphology during the setting phase which fundamentally dominates the structure formation. The scope of this paper is to provide an understanding of the processing temperature's influence, in this context mould temperature, on the morphological and tribological properties of injection-moulded microparts. Furthermore, the characteristics of tribological testing conditions in microparts should be identified with regard to optimized testing methods. Results indicate that the tribological properties of microparts are mainly influenced by nature of the skin near layers, which can be greatly improved through the application of mould temperatures close to the crystallisation temperature. Additionally, a tribological testing method is adapted for a correct and high solution of the running-in and stationary phase in order to identify the effects of the skin layer on the wear behaviour.
