PRODUCTION MANAGEMENT SYSTEM ON THE TECHNOLOGY CORRESPONDING TO ELECTROMAGNETIC COMPATIBILITY FOR ELECTROMAGNETIC ENVIRONMENT PRESERVATION
The electronic devices used for informationcommunication, machine control, etc. , have possibility to emit unnecessary electromagnetic waves while they perform original functions, and those electromagnetic waves possibly become obstacles such as interference to other electronic devices and inducement of malfunction. Po tential damage on human health is also another concern. Therefore it is socially required to establish technological countermeasures to realize electromagnetic com patibility. As technological solutions, there are two ways: devising a design of electronic circuit or adding elec tromagnetic wave shielding functions to housings. We need to construct solutions based on both of those two as pects. This research examines optimization for production management systems focusing on the latter way. Through the research activities we clarified that injection molding based on the composite of extrafine metal fi ber and polymer matrix is most appropriate to create electromagnetic wave shielding function. (1) Optimization of molding dice structure and molding condition control technology is effective to im prove dispersibility of extra-fine metal fibers and performance of shielding function against electromagnetic waves. (2) Fiber type materials with large aspect ratio are effective to perform shielding function against electro magnetic waves. In addition, preventing degradation of polymer matrix with structural function is required from the quality reliability viewpoint. From the aspect, extra-fine stainless steel fiber is most suitable. (3) Polymer matrix with the role of structural function needs mechanical strength, high- level thermal du rability and high-quality moldability, and use of engineer plastics is effective from the quality reliability view point.
