Metal injection molding (hereinafter referred to as MIM) is a large-scale production technology for small parts with complex shapes. It has been widely used in electronic products. In recent years, it has been applied to medical devices. With the development of minimally invasive surgery, the integration and miniaturization of various parts have also made MIM process more and more important. This process will produce injection defects on the finished products, which will seriously affect the appearance and even the strength of the finished products.
In this thesis, we discuss the development process of a new medical component, and compare the actual situation by a analysis software - Moldex3D CAE, then draw up and estimate the situation after improvement.
The analysis result shows that using CAE simulation analysis technology can effectively pre-discover the defect positions in the mold design. Designers can virtually test products in a digital environment, greatly reducing the time and cost lost by traditional trial-and-error method. Through simulation analysis, the possibility of injection defects can be identified in advance, and the design can be optimized to improve the quality and performance of the finished products.
This research is of great significance for improving the development efficiency and product quality in MIM process. By using CAE simulation analysis, designers can more accurately evaluate and optimize mold design to reduce injection defects, and improve consistency and reliability of products. This will help to speed up the development process of medical parts while saving time and cost, improving production efficiency and product competitiveness.
