This category focuses on companies involved in designing and supplying largely automated systems for assembling a variety of manufactured products. It includes equipment for automatically fastening, riveting, drilling, screw insertion and tightening, and performing similar operations that would otherwise have to be done manually. It also extends to systems and devices for testing and packaging finished products. Note: In effect, the sites indexed here are concerned only with a particular aspect of automated manufacturing. Those that deal with other - and often more extensive - forms of automation belong in - and should be directed to - the main category at http://dmoz.org/Business/Industries/Manufacturing/Factory_Automation/ or one of its subcategories.
