Closed-mouri tou, ki rele tou enpresyon-mouri tou, ka pwodwi yon varyete prèske illimité nan fòm ki ranje nan pwa soti nan ons sèlman nan plis pase 200kg. Kòm non an implique, de oswa plis mouri ki gen enpresyon yo te pote ansanm kòm forging stock subi deformation plastik. Paske mouri a mete restriksyon sou koule metal, pwosesis sa a ka sede fòm pi konplèks ak pi pre tolerans pase louvri-mouri tou. Enpresyon-mouri forè kont pou majorite nan aliminyòm tou, tankou pwodiksyon.

Closed-die forging, also known as impression-die forging, can produce an almost limitless variety of shapes that range in weight from mere ounces to more than 200kg. As the name implies, two or more dies containing impressions are brought together as forging stock undergoes plastic deformation. Because the dies restrict metal flow, this process can yield more complex shapes and closer tolerances than open-die forging. Impression-die forging accounts for the majority of aluminum forging production.
