A network transmission system and a method thereof are disclosed in the invention. A storage cost estimate unit 112 calculates storage cost before and after restructure by using catalog information included in a database 122. As the lamp ages, its electrodes deteriorate, reducing the amount of light directed into a light guide and ultimately onto the adhesive. The finite state automata are then programmed in Programmable Intelligent Search Memory programmable FSA rule blocks and the compressed signature database is programmed in the PRISM signature search engines for evaluating content with the content search rules. In order to increase the productivity, the method mentioned at the start is further developed by the present invention in that a core produced in a first injection molding cycle is coated with a plastic component in at least one subsequent injection molding cycle so as to form a multi-layered grip piece.
