Fabrication simulation technology applied to resin component design

摘要

Fujitsu Ten has been pursuing advanced resin molding technology, seeking to replace metal parts with resin, integrate multiple parts into single resin molds, and, ultimately, reduce product weight and production cost. However, since resin partsare becoming highly advanced and complex in shape, it has become difficult to take measures to minimize warping and shape deformation during the molding process. To solve this problem, we installed a resin rheological analysis system in 1997. Usingrheological analysis, we conduct fabrication simulations in the initial parts design stage, and predict possible generation of flaws. This information helps us take necessary measures against deformation in the design stage, thus allowing us to minimizeshape defects in the molding process and reduce resin part development time.An outline of the resin rheological analysis system follows, including an example of its successful application in resin part development for a CD changer deck mechanism. In the case cited, a 20% reduction in the development period was obtained.
