Parametric modeling and configuration design method are a important methods for rapid design in manufacturing. This paper proposes a relation rules which parametrically models a bonnet trimming tool based on Pro/Engineer. The concept of desogn is applied a trimming die of the bonnet outer panel. Trimming die have a many parameters. Each a parameter is related the die face and punch profile. A design system consists of a Pro/Engineer, a Pro/program.

A novel electroplating process is described and effects of anode lay-out thickness distribution and on platiting rate are discussed. Microphotograhic analysis indicates are compact and less "POROUS " than of barrel and rack. With this process production cost reduction and capacity increase could be achieved by a rate of 60% and 97% respectively, as compared to our present barrel plating process. This process disclose a number of beneficial processes such as color coding system on TO-92 package and development of a new tin bath formula.
