충격내구성을 고려한 자동차 도어트림 미세망 스피커그릴 개발

The object of this research is fineness net speaker grille design and mold development and test analysis specification standardization. We established main design factor that influence in quality for speaker grille of door trim that is required from customer, achieved design optimization, and established manufacture standard, test method and test specification for request quality. We developed process for confirmation about reliability of speaker grille of door trim. We will apply process in new model design project. We apply product that study on deluxe car and will contribute to high-quality improvement. We studied actively about design condition grasping, product design technology acquirement, material application, localization of mold technology about fineness net. Injection molding technology for production, confirmation about reliability and specification and cost down through reduction of process. Result presentation of design condition, mold technology, injection molding technology and confirmation about reliability, etc consisted about fineness net speaker grille that is preceding product. Effects are world competitive power increase as engineering technology and reliability construction test method and standardization process settlement. Plan is world market conquest as apply to high-class automobile and cost down through localization, reduction of process.
