1. Kutsini kukhipha .
Lensimbi lesemantini itfululelwa emgodzini wesikhunta ngesimo lesifanele lencenye, bese ngemuva kwekutsi seyicinile, umkhicito wencenye lonesimo lesitsite, bukhulu kanye nelizinga lemhlabatsi uyatfolakala, lokubitwa ngekutsi kufaka. Tintfo letintsatfu letinkhulu: alloy, kumodela, kutfulula kanye nekucinisa. Inzuzo enkulu: tincenye letiyinkimbinkimbi kungakhiwa.
2. Kutfutfukiswa kwekukhipha
Kukhicita kwacala ngemnyaka wa 1930 kusetjentiswa imishini yemoya kanye netinchubo tesihlabathi selibumba lekufakelwa.
Luhlobo lwesihlabathi sesimende lwavela nga-1933
Nga-1944, kwavela luhlobo lwegobolondvo lesihlabatsi lesine-resin lecinile lebandzako .
CO2 emanti lacinile engilazini yesihlabathi sikhunta savela nga 1947
Nga-1955, kwavela luhlobo lwegobolondvo lesihlabatsi se-resin lembonya ngekushisa .
Nga-1958, kwavela sikhunta sesihlabathi se-furan resin lengabhakwa .
Nga-1967, kwavela sikhunta sesihlabathi lesigeleta simende .
Nga-1968, kwavela ingilazi yemanti lene-organic hardener .
Eminyakeni lengu 50 leyengcile, tindlela letinsha tekwenta tikhunta tekukhicita ngetindlela letibonakalako, njenge: kubumba ema pellet emaginethi, indlela yekubumba nge vacuum sealing, kubumba igwebu lelahlekile, njll Tindlela letehlukene tekukhicita letisekelwe etikhunjini tensimbi. Njengekulahlwa kwe-centrifugal, kulahlwa kwemfutfo lomkhulu, kulahlwa kwemfutfo lophansi, kukhishwa kwemanti, njll.
3. Timphawu tekukhipha
A. Kuvumelana nesimo lokubanti kanye nekugucugucuka. Yonkhe imikhicito yetintfo tensimbi. Kuphosa akukhawulelwa sisindvo, ubukhulu kanye nesimo sencenye. Sisindvo singasuka kumagremu lambalwa kuya kumakhulu emathani, bukhulu belubondza bungaba kusuka ku 0.3mm kuya ku 1m, futsi kwakheka kungaba tincenye letiyinkimbinkimbi kakhulu.
B. Liningi letintfo letiluhlata naletisitako letisetjentiswako titfolakala etindzaweni letinyenti futsi tishibhile, njengensimbi lelahliwe kanye nesihlabathi.
C. Castings kungenta ncono kuciniseka dimensional kanye nekhwalithi ebusweni castings ngebuchwepheshe phambili casting, kute tincenye tingajutjwa kancane futsi ngaphandle kwekusika.
