Introduction
Process manufacturing is the process of creating items by combining raw materials according to a formula or recipe. Production is completed in batch or semi-continuous processes.
These manufacturing systems might include batch methods such as mixers, batch reactors, and extruders or semi-continuous methods such as plug-flow reactors, fiber manufacturing, and looms.
Production is completed in batches with a standard batch size and might contain an overall yield along with a scrap factor, such as what is found in chemical reaction manufacturing.
In process manufacturing when certain items are bought or sold, they are measured by weight or volume instead of by the object itself, which is known as catch weight items.
