Rohteils

Rohteils, plural of Rohteil, is a term used in manufacturing and engineering to describe semi-finished components that have undergone initial forming steps but are not yet finished to final specifications. They are intermediate goods intended for subsequent processing to become finished parts. Rohteils can be made from metals, plastics, or composites and may take forms such as rough castings, forgings, extruded profiles, or machined blanks.

In the production and supply chain context, Rohteils sit between raw materials (Rohstoffe) and finished parts (Fertigteile). They are produced by processes like casting, forging, extrusion, or pre-machining, and they require additional operations such as precise machining, heat treatment, surface finishing, or final assembly to meet design tolerances and performance requirements. Rohteils are typically stocked or scheduled for later processing, with lead times and quantities managed according to production planning needs.

Quality and specification of Rohteils differ from finished parts. They usually carry coarser geometries and tolerances, and their surface condition may be designated as as-cast, as-rolled, or pre-machined, depending on the process. Selecting appropriate Rohteils involves design for manufacturability, consideration of downstream finishing steps, and cost optimization to minimize waste and processing time.

Related terms include Halbzeug (semi-finished product), Guss- oder Schmiedeteile (cast or forged parts), and Fertigteile (finished parts). Rohteils play a key role in manufacturing strategies, inventory management, and procurement practices.
