【正文】 equirements, and an increase in production costs. embedded design using the cavity structure. The structure widely used in small and mediumsized plastic parts mold. Processing methods use ordinary machine, CNC machine tools, 2 / 58EDM, LIGA methods. Will be embedded in a cavity of a whole cavity plate, Embedded in the cavity material available lowcarbon or low alloy steel, carburizing quenching after polishing. After production confirmation, this mold structural design ingenious, the ease of operation, the service life is long, models to achieve the specification.keywords： handset battery charger
