Maikutlo a macha a ho boloka matla a hloka ntlafatso ea moralo ka ho theola likarolo le ho khetha lisebelisoa tse hananang le ho bola tse nang le matla a phahameng ho latela maemo a tekano. Ho fokotsa likaroloana ho ka etsoa ka ho ntlafatsa sebopeho kapa ka ho kenya lisebelisoa tse boima sebakeng sa tse bobebe tse phahameng. Tabeng ena, forging e phetha karolo ea bohlokoa tlhahisong ea likarolo tsa sebopeho se ntlafalitsoeng. Setsing sa Mechini ea Metal Forming le Metal-Forming Machines (IFUM) ho entsoe mekhoa e fapaneng ea mahlale ea ho qapa. Mabapi le ntlafatso ea meralo, ho ile ha batlisisoa maano a fapaneng a ho matlafatsa likarolo tsa lehae. Mathata a bakoang ke sebaka sa heno a ka 'nang a thatafalloa ke ho sebetsa ka thata tlas'a khatello e matla ea hydrostatic. Ntle le moo, libaka tse laoloang tsa martensitic li ka etsoa ka ho theha phetoho ea karolo e susumelitsoeng ka har'a litšepe tsa metastable austenitic. Liphuputso tse ling li ile tsa shebana le ho nkeloa sebaka ha likarolo tse boima tsa tšepe tse nang le li-alloys tse nonferrous tse matla haholo kapa metsoako ea lintho tse nyalisitsoeng. Ho ile ha qaptjoa mekhoa e mengata ea magnesium, aluminium le titanium alloys bakeng sa lisebelisoa tse fapaneng tsa sefofane le likoloi. Ketane eohle ea ts'ebetso ho tloha ho sebopeho sa thepa ka moralo o thehiloeng ho ketsiso ho isa tlhahisong ea likarolo e shebiloe. Ho netefalitsoe hore ho na le monyetla oa ho etsa li-geometri tse nang le sebopeho se rarahaneng ho sebelisa li-alloys tsena.
