Plural of extrusion; objects or shapes created by pushing or forcing material through an opening or die.
From extrude plus -ion (forming nouns from verbs), then pluralized with -s. The -ion suffix comes from Latin and is one of the most productive noun-forming suffixes in English.
Extrusions are everywhere in modern manufacturing—aluminum window frames, plastic pipes, weather stripping, even the bristles in your toothbrush are extruded! It's one of the most efficient manufacturing processes because it combines shaping and forming into a single step.
