Engineering Materials

Engineering materials is a discussion led by Design News Contributing Materials Editor Doug Smock on important new developments and applications that affect mechanical design. Metals covered include all types of steel and nonferrous metals, in all shapes. Resins covered include nylons, polycarbonates, polysulfides, polyimides, and polybutylene terephthalate (PBT). Other materials covered include ceramics and rubber. Topics covered include materials enhancement, new applications, process technology, tooling, sustainability, and economic issues. Posts will include latest news from global events such as K 2007, the Alliance of Plastics Processors Annual Conference, the National Plastics Exposition, and the annual technical conference (ANTEC) of the Society of Plastics Engineers.

Complex Assembly Process Used for Fuel Cell

Three advanced plastics welding processes are used in a novel fuel cell based on electroconducting polymer and transition metals in an effort to avoid use of adhesives. “We are using orbital vibration to weld the different membranes (anode and cathode) producing the energy,” comments Didier Perret, sales manager of Branson Ultrasonics in Switzerland. “We are using advanced ultrasonic welding for several assembly operations (to replaces screw, glue or others). And finally we use the latest infrared laser technology GEN 3 to weld the fuel tank with a high safety level.”

Is the chemical enviroment acid? or base? Has the weld process been tested for durability in this enviroment? What pressure does the weld have to hold?
