This category contains sites involved in the design and building of one-of-a-kind machines and equipment for a wide range of manufacturing and processing companies. The emphasis is on a needs analysis, appropriate conceptual design, and eventual production and installation. Note: Any firm that simply offers customized machinery in its customary field of equipment should direct its site to the category in which it and its competitors are normally to be found. Thus, a special purpose laminating machine manufacturer belongs in the Converting category, while a company offering customized industrial heating equipment should be allocated to the Furnaces,_Incinerators,_Kilns one. Note: Some parallel exists between this Custom Machinery Builders category and the Technical Services one, in which, there too, the emphasis is on a source of advice and supply that a given manufacturer is unlikely to find available within the normal scope of things.
