Forged: isando sokwakha sebenzisa amandla okuthinta aphindaphindayo noma ingcindezi yokucindezela ngakho-ke sidinga ukushintsha umumo ongenalutho nosayizi wendlela yokucubungula ingcindezi.

I-Extrusion: insimbi yensimbi ibekwe ku-extrusion evaliwe uJane, faka ingcindezi engxenyeni eyodwa yensimbi kusukela egodini le-die ukuze uthole i-extrusion enqunywe kusengaphambili inomumo ofanayo nosayizi wendlela yokucubungula umkhiqizo ophelile esetshenziselwa ukukhiqizwa kwensimbi yensimbi engeyona ayoni. .

Ukugingqika: insimbi engenalutho yensimbi ngokusebenzisa ipheya yegebe (yesimo esihlukahlukene) imiqulu ezungezayo, ngenxa yokucindezelwa komqulu wesigaba esiphambanayo kuyancishiswa, ubude bendlela yokucubungula ingcindezi eyengeziwe.

I-Pullout: insimbi egoqiwe ingenalutho (uhlobo lweshubhu, imikhiqizo, njll.) ngokusebenzisa ukudayela kwe-die orifice ekuncishisweni okuncishisiwe kwengxenye edonsayo ubude okwandayo kokucubungula kusetshenziswa kakhulu kubanda.
