Randteil

Randteil is a German term used in technical and manufacturing contexts to denote the edge portion of a component or the part located near the boundary of a workpiece. The word is a compound of Rand (edge, border) and Teil (part). Its exact meaning is not standardized and can vary between industries and companies, but it generally refers to a portion of a part that lies at or near its outer boundary, or to a marginal component that interfaces with another part.

In practice, Randteil may be identified in engineering drawings to draw attention to edge-related processes such as deburring, chamfering, or edge finishing, or to designate a functional edge such as a lip, flange, or seal interface. It can also describe material that is intended to be machined away or left as a border after trimming, depending on the specific design and production workflow.

Because Randteil is not a universally standardized term, its translation into English is context dependent. It is commonly rendered as edge part or border part in technical documents, but the precise scope should be inferred from the accompanying drawings or specifications.

Related concepts include Rand and Teil as individual words, as well as edge-related terms such as Kante (edge) and Flansch (flange). The usage of Randteil is primarily found in German-language engineering literature, technical manuals, and multinational manufacturing contexts where German terminology is employed.
