Optical mold industry at Taiwan attacked by downstream industry continue move out in recent year and financial crisis effect at last year, bring deep decrease about inter-market. Originally for mass marketing exclusive by cheep prices, it’s emerge M-type of distribution by face Strength competition of middle & low price mold at China & Korea and optical production’s mold need high nano-machine. It is very difficult in integrated business environment. So we need think transfer target at mold factory owner in Taiwan and focus research product & technology and talented person training toward explicit mold’s encumbrance of technology R&D、Knowledge Management、Intellectual Property、Business Intelligence by HI-EXACTNESS、HI-SPEED、HI-DEEP&WIDE Ratio. In order to enhance the added value of products with the mold talent forward-looking layout, would not only be a result of rapid change in industry trends, more is eternal survival, The mold industry is the foundation of the industrial products, and it’s also act an important Role . In order to objectively diagnose their relevance, companies need to allow flexibility to fine-tune the organizational structure, so that the major functions of various departments to play to the best performance processes.

Research target for exploring ways through data mining optical mold industry in key performance index and dies for the optical industry's key performance index developed for an analysis, a view to die for our industry to give an innovative and forward-looking direction of development.
