1. Ho lahla: Ke mokhoa oa ho qhibilihisa tšepe ka har'a mokelikeli o finyellang litlhoko tse itseng ebe o o tšela ka har'a hlobo.Kamora ho pholile, ho tiisa le ho hloekisa, ho lahla (karolo kapa sekheo) se nang le sebopeho se reriloeng esale pele, boholo le ts'ebetso li fumanoa.Theknoloji ea mantlha ea indasteri ea ho etsa mechini ea sejoale-joale.

Ka 3200 BC, lihoho tsa koporo li ile tsa hlaha Mesopotamia.Pakeng tsa lekholo la bo13 la lilemo BC le lekholo la bo10 la lilemo BC, China e kene sehlohlolong sa mehala ea boronse.

Hoo e ka bang lekholong la bo8 la lilemo, Europe e ile ea qala ho hlahisa lihlahisoa tsa tšepe.Kamora Phetohelo ea Liindasteri lekholong la bo18 la lilemo, li-castings li kene nakong e ncha ea ts'ebeletso ho liindasteri tse kholo.
Lekholong la bo20 la lilemo, tsoelo-pele e potlakileng ea ho lahla e 'nile ea ntlafatsoa.Nodular cast iron, alloy cast iron, ultra-low carbon stainless steel, koporo ea aluminium, silicon ea aluminium, le li-alloys tsa aluminium-magnesium li entsoe ka ho latellana.
Lisebelisoa tsa tšepe tse kang titanium-based le nickel-based alloys, 'me ba qapa mokhoa o mocha oa ho kenya tšepe e bohlooho.Kamora lilemo tsa bo-1950, ho ile ha hlaha mohlala o phahameng oa khatello ea lehlabathe le metsi,

Ho na le mefuta e mengata ea ho lahla, e arotsoeng ka: ①Tloaelo e tloaelehileng ea lehlabathe, ho kenyelletsa le mefuta e 3 ea lehlabathe le letala, lehlabathe le omeletseng le lehlabathe le thatafalitsoeng ke lik'hemik'hale.②Ho lahla ka mokhoa o khethehileng, ho ea ka lisebelisoa tsa mohlala, ho ka aroloa ka ho lahla ho khethehileng ka lehlabathe la tlhaho la liminerale le lehlohlojane e le lisebelisoa tse ka sehloohong tsa mohlala (tse kang ho kenya lichelete, ho lahla letsopa, ho lahla likhetla tsa workshop, khatello e mpe ea khatello, ho lahla ka thata, ho lahla ceramic) Joalo-joalo) le ho lahla ho khethehileng ka tšepe e le thepa e ka sehloohong ea hlobo (e kang ho lahla hlobo ea tšepe, khatello ea khatello, ho lahla ho tsoelang pele, khatello e tlaase, ho lahla centrifugal, joalo-joalo).
6. Ts'ebetso ea ho lahla hangata e kenyelletsa: ①Ho lokisoa ha hlobo (lits'oants'o tse etsang tšepe ea metsi hore e be li-castings tse tiileng).Mefuta e ka aroloa ka lehlabathe, tšepe, ceramic, letsopa, graphite, joalo-joalo, ho latela palo ea linako tse sebelisoang.Bakeng sa ho lahloa, ho sa feleng le ho sa feleng, boleng ba ho lokisetsa hlobo ke ntho e ka sehloohong e amang boleng ba li-castings;②Ho qhibiliha le ho tšolloa ha litšepe tse entsoeng, litšepe tse entsoeng ka tšepe (li-alloys) haholo-holo li kenyelletsa tšepe e entsoeng ka tšepe, tšepe e entsoeng ka tšepe le li-alloys tse se nang ferrous;③ Ts'ebetso ea ho lahla le ho hlahloba.Ts'ebetso ea ho lahla e kenyelletsa ho tlosoa ha 'mele oa linaha tse ka ntle ho motheo le holim'a li-castings, ho tlosoa ha li-rosers tse tšolohang, ho hlajoa ha li-burrs le li-drape seams, hammoho le phekolo ea mocheso, sebōpeho, phekolo e thibelang mafome le ho sebetsa ka thata.Kenya valve ea pompo
