What does extruding mean?
"Extruding" is the present participle of the verb "extrude," which means to force, press, or thrust something out — most commonly by pushing a material through a shaped opening called a die. In industry, extruding is fundamental to making products such as plastic pipes, aluminium profiles, pasta, and bricks: soft raw material is heated, then squeezed continuously into a fixed cross-sectional shape. The word also carries a broader physical sense, describing anything that protrudes or projects outward, such as lava extruding from a volcano or a tooth extruding beyond the gum line in dental contexts. Derived from the Latin extrudere, formed from ex- ('out') and trudere ('to thrust'), it entered English in the sixteenth century and retains a formal, technical register today. Its close relatives include intrusive, obtrusive, and protrude, all built on the same thrusting root. For anyone describing how things are shaped, expelled, or pushed outward, "extruding" offers a precise, vivid verb.

Etymology of extruding
"Extruding" derives from the Latin extrudere, meaning 'to thrust out' or 'to drive out,' formed from ex- ('out') plus trudere ('to thrust, to push'). The verb entered English in the sixteenth century, initially carrying senses of expelling or driving out before developing its characteristic industrial meaning. It shares this thrusting root with words such as intrusive, obtrusive, protrude, and abstruse, all tracing back to trudere.

How extruding is actually used
"Extruding" is chiefly a technical term used in engineering, manufacturing, geology, and dentistry, so it reads as formal in everyday contexts. The industrial sense (forcing material through a die) is far more common than the physical sense of merely sticking out, which is usually better expressed by words like "protruding" or "jutting."
