2 Component Micro - Injection Molding Technology For Manufacturing Of High Precision Micro Parts - A systematic project approach

摘要

The project set itself the goal of the new possibilities of micro-injection molding of shotweight-optimized two component micro parts in regards of quality, flexibility and cost, including in-line measurement and testing with the stages of assembly, handling and logistics in the territory of the production of micro-optical systems. Based on the new machine concept of a two-component micro - injection machine (2C-μIMM) a flexible and compact example of supply chain for the production of reliable optical systems were developed. The process chain contains the technologies of high precision micro injection molding technology, Quality-control by optical control and geometric dimension and shape measurement, separation procedures of the runner and further assembly steps. A process-handling technology with special grippers combines and automates the individual process steps. An optoelectronic sensor, and an application with microfluidic functions for Biotechnology (so called Demonstrators) were selected to test the developed system. In both cases, all stages of product development from product design to be included on replication by injection molding, assembly and integration of handling opereations of the components had to be evaluated. The development of a scalable manufacturing technology for both examples is essential, and will be pursued as a priority.The project provides a variety of results: A novel, multi-flexible manufacturing plant for the production of future-oriented products, innovative individual modules, new and improved production methods and advanced micro-optic products.
