An optimal robust design methodology has been developed to minimize the warpage in a decorating panel of monitor molded by the plastic injection. For the associated methodology, the Taguchi's Design Of Experiment (DOE) based on orthogonal arrays and Signal-to-Noise Ratio is combined with commercial simulation tools f3r injection molding. An optimal robust design solution is statistically resulted from the computational simulation. The related experiment was done for evaluations of the warpage in the decorating panel part of monitor. This research showed that the warpage under the applied optimal design conditions was comparatively reduced.

Carbon board, an electromagnetic shielding new material, is expected to be applied to the art wall by combining draft designs. When environment-friendly architecture materials are used as an interior wall, they are suitable as finishing materials. According to the increasing tendency of the application of carbon board, various styles could be made by decorating the whole or a part of a wall with tiles with module structure or by patterning the wall with panel-type woodcut or pictures or sculpture. And more graphic design based on diverse variation, and reconstruction and combination between other motif is being on the rise as a new expression. In this paper, make it possible to applying in MDF board and carbon board pattern design using the woodcut technique. The structural and physical properties were compared by usability of abrasion, toughness, stability. Samples are analyzed dependent on the hardness and relative density, change of detail pattern design and trimming technique. These results have shown that the possibility of applying of carbon board can be a high rank interior materials, capable of creating value of the living system, connects with MDF board, also can express humanism in a beautiful manner.
