Ukufakwa kwe-investimenti, okubuye kwaziwe ngokuthi i-wax casting elahlekile, ivame ukusetshenziswa ekusakazeni amandla adonsela phansi ngokunemba: khetha izinto ezifanele zokutshala izimali (ezifana nopharafini) ukwenza isikhunta sokutshala imali;cwilisa ngokuphindaphindiwe i-refractory coating kusikhunta sokutshala imali, ufafaze isihlabathi esiphikisayo, wenze igobolondo lesikhunta libe lukhuni futhi lome, bese uncibilikisa isikhunta sokutshala imali sangaphakathi ukuze uthole umgodi wokubumba;bhaka igobolondo lesikhunta ukuze uthole amandla anele, ushise izinto ezisele zokubumba utshalomali;ukuphonsa kudinga ukuqinisa nokupholisa izinto zensimbi, Ngemuva kokugoqa, ukuchithwa kuzokwenziwa ukuze kutholwe imikhiqizo eqediwe enembayo ephezulu.Ukwelashwa kokushisa, ukucubungula okubandayo kanye nokwelashwa kwendawo kuzokwenziwa ngokuvumelana nezidingo zemikhiqizo.

Izimboni ezikhiqiza isihlabathi nezikhiqiza ngobuningi kufanele zidale izimo.Ulayini wokukhiqiza we-shaker yakudala noma umshini wokubumba we-shaker one-molding ethuthukisiwe nezindlela zokwenza umnyombo awuphezulu ngokwanele, amandla okusebenza kwabasebenzi aphakeme, umsindo uphakeme, futhi awufaneleki izidingo zokukhiqiza ngobuningi.Ama-castings amancane kufanele aguqulwe isinyathelo ngesinyathelo Umugqa wokukhiqiza umshini wokubumba ovundlile noma ome mpo unomsebenzi ophezulu wokukhiqiza kanye nendawo encane yaphansi.Ngokusakazwa kosayizi ophakathi, imigqa ehlukahlukene yokukhiqiza umshini wokubumba enengcindezi enomzimba webhokisi kanye nemigqa yokubumba yomthelela womoya ingakhethwa.Ukuze kuhlangatshezwane nezidingo zemigqa yokukhiqiza yokubumba esheshayo nenembayo, indlela yokwenza ingqikithi ingakhethwa njengalokhu: ukukhiqizwa okuphezulu kwebhokisi eliwumgogodla obandayo, ibhokisi elishisayo elishisayo, umgogodla wegobolondo nezinye izindlela eziyinhloko.

I-resin self-harding sand molding and core making ingacatshangelwa njenge-castings enkulu naphakathi.Ngokwehliswa okukhulu ekukhiqizeni ama-batch amancane, ukumodela okwenziwa ngesandla kuseyindlela ebalulekile.Ukumodela okwenziwa ngesandla kuyavumelana nezimo ukuze kuhlangatshezwane nezidingo ezihlukahlukene eziyinkimbinkimbi futhi akudingi imishini eminingi yokucubungula.Isikhunta sesihlabathi sengilazi yamanzi, isikhunta sesihlabathi sengilazi ye-VRH yamanzi, i-organic ester water glass self-harding sand mold, isikhunta sesihlabathi esomile sobumba, isikhunta se-resin self-harding sand kanye nesikhunta sesihlabathi sikasimende singasetshenziswa;kuma-castings amakhulu akhiqizwa ucezu olulodwa, indlela yokubumba umgodi inezindleko eziphansi zokukhiqiza, isivinini sokukhiqiza esisheshayo, kanye nokukhiqizwa ngobuningi noma ukukhiqizwa kwesikhathi eside kwemikhiqizo eqediwe, ifaneleka kakhulu ekubunjweni kwamabhokisi amaningi kanye nebhokisi elincane nakuba ukutshalwa kwezimali kwe isikhunta nebhokisi lesihlabathi liphezulu, Kodwa linganxeshezelwa ngezici zokonga isikhathi sokwenza kanye nokuthuthukisa ikhwalithi yomkhiqizo.

Ukukhipha umfutho ophansi, ukusakaza okufayo, ukusakaza okumaphakathi nezinye izindlela zokulingisa zifaneleka kuphela ukukhiqizwa ngobuningi ngenxa yenani eliphezulu lemishini kanye nesikhunta.

Isibonelo, iphinde isetshenziselwe ukukhiqiza amathuluzi emishini emikhulu nokunye ukulingisa.Ngokuvamile, indlela yokwenza ingqikithi isetshenziswa esikhundleni sokwenza isikhunta nebhokisi lesihlabathi kwamanye amafekthri.Amabhizinisi anamaphethini ahlukene enziwe ngendlela yokwenza ibhokisi lesihlabathi anezimo ezihlukene zokukhiqiza (okuhlanganisa amathuluzi, indawo, ikhwalithi yabasebenzi, njll.), imikhuba yokukhiqiza nolwazi oluqoqiwe.Ngokwale mibandela, kufanele sicabangele ukuthi yimiphi imikhiqizo efanelekile nokuthi yimiphi ekhiqizwa Umkhiqizo awufanele.

Izindlela zokulingisa ezihlukene zinokunemba okuhlukile, ukutshalwa kwezimali okuhlukile kokuqala kanye nokukhiqiza, kanye nezinzuzo zokugcina ezihlukene zezomnotho.Ngakho-ke, ukuze kuzuzwe okwengeziwe, ngokushesha, okungcono nokuncane, kuyadingeka ukucubungulisisa zonke izici zezindlela zokusakaza ezikhethiwe zokulinganisa izindleko zangaphambili, ukuze kunqunywe izindlela zokusakaza ezinezinzuzo eziphezulu zezomnotho nokuqinisekisa izidingo zokusakaza.

Nakuba ukuthuthukiswa kwemboni yokusungula yaseChina kusesikhathini esinzima uma kuqhathaniswa, ngokuhamba kwesikhathi, lisekhona ithemba lokuthuthukiswa kwemboni yezokukhiqiza yaseChina, isidingo semakethe sesiqale ukukhula kancane, futhi ngamandla aqinile aseChina. ukuthuthukiswa kwemboni eyisisekelo, ngikholwa ukuthi imboni yaseShayina izokwenza impumelelo egculisayo.

Ochwepheshe bathi ukuze sithuthukise ngokuyisisekelo izinga lobuchwepheshe bokusakaza, kufanele senze la maphuzu amane alandelayo:

I-1, Iwukuthuthukisa ubuchwepheshe bokulingisa, ukuthuthukisa ukunemba kokubikezela, ukuqinisa ukulawulwa kwenqubo, ukuthuthukisa ukubamba ukujwayela kokukhiqiza, okuthinta ukuphuma kokukhiqizwa kwenqwaba.

2, Kuyinhlanganisela yokukhiqiza, ukufunda nocwaningo ukuthi amabhizinisi akufanele nje athuthukise ukuqwashisa kwawo emisha kanye nekhono le-R & D, kodwa futhi anamathisele ukubaluleka futhi aqinise inhlanganisela yokukhiqiza, ukufunda nokucwaninga, okusekelwe ikakhulukazi ekubunjweni okunembayo. amabhizinisi.

3, Kuyisisekelo semboni ukunamathisela ukubaluleka ocwaningweni nasekuthuthukisweni kwezinto ezibonakalayo.Okwamanje, usemkhulu umsebenzi okufanele wenziwe.Emkhakheni we-Aeronautics and Astronautics, ucwaningo kanye nobuchwepheshe bokuncibilika kwezinto ze-alloy, ikakhulukazi ama-superalloy, kufanele kuthuthukiswe, futhi kunegebe elikhulu namazwe angaphandle.

4, Ngakho-ke, ucwaningo nokuthuthukiswa kwemishini yokuphonsa enembile kuseyindawo eshisayo.
