Inrun

Inrun is a term used in several technical contexts, and it does not have a single, universally accepted definition. In many manufacturing and automation settings, the word is used informally to denote the portion of a process, line, or machine into which materials or parts enter for processing. The in-run is typically distinguished from the out-run, which covers discharge or finished-product flow. The exact meaning, length, and safety considerations of an in-run are specific to the equipment and process, and engineers may use different terminology such as infeed, loading zone, or entry run.

Outside manufacturing, the term may appear in niche writings to describe a phase or segment that occurs as something begins to run or is introduced into a sequence. In such uses, the meaning is highly dependent on the discipline and the authors’ conventions, and there is no standardized definition across fields.

Etymologically, inrun is a compound of in and run, reflecting the notion of movement into a system or process. Because the term can vary in meaning by context, readers should consult domain-specific manuals, diagrams, or glossaries when encountering inrun in technical literature. See also infeed, loading zone, conveyor, and discharge or out-run for related concepts in production and process flow.
