Ukukhishwa kwe-investimenti, okwaziwa nangokuthi ukukhishwa kwe-wax elahlekile, kwadalwa eminyakeni engu-5,000 edlule.Le ndlela yokuphonsa ihlinzeka ngezingxenye ezinembile, eziphindaphindwayo neziguquguqukayo ezinezinsimbi ezihlukene kanye nama-alloys okusebenza okuphezulu.Le ndlela yokulingisa ifanele ukusakaza iphunga nezingxenye ezinembayo futhi ibiza kakhulu kunezinye izindlela zokulingisa.Ngokukhiqiza ngobuningi, izindleko zeyunithi zizokwehla.
Inqubo yokutshala izimali:
Ukwenza Iphethini Ye-wax: Abakhiqizi bokutshala imali kufanele benze amaphethini we-wax ekubunjweni kwabo kwe-wax.Izinqubo eziningi zokusakaza utshalomali zidinga ama-wax asezingeni eliphakeme ukuze aqedele lesi sinyathelo.
Umhlangano wesihlahla se-wax: Izindleko zokukhiqiza umkhiqizo owodwa wokutshala imali ziphezulu, futhi ngokuhlanganiswa kwesihlahla se-wax, abakhiqizi bokutshala imali bangakha isivuno esiningi.
Ukwenza amagobolondo: Yenza izikhwama zamagobolondo ezihlahleni ze-wax, ziqinise futhi uzisebenzise enqubweni yokuphonsa elandelayo.
Ukukhipha i-wax: Ukukhipha i-wax ngaphakathi kuzohlinzeka ngomgodi lapho ungathela khona insimbi encibilikisiwe emgodini ophelile.
Igobolondo liyaphuma: Ngemva kokuba insimbi encibilikisiwe iqina, susa igobolondo ukuze uthole isihlahla somkhiqizo wensimbi.Zisike esihlahleni futhi uzoba nomkhiqizo wokugcina wokutshala imali.
Izici zobuchwepheshe:
1. Ukunemba okuphezulu kwe-dimensional kanye nokunemba kwejometri;
2. Ubulukhuni obuphezulu;
3. Ingakwazi ukuphonsa ama-castings anezimo eziyinkimbinkimbi, futhi ama-alloys azophonswa awanqunyelwe.
Ukungalungi: inqubo eyinkimbinkimbi kanye nezindleko eziphezulu
Isicelo: ilungele ukukhiqizwa kwezingxenye ezincane ezinobumo obuyinkimbinkimbi, izidingo zokunemba okuphezulu, noma okunzima ukwenza okunye ukucutshungulwa, njengama-blade enjini ye-turbine, njll.
1. Ingakwazi ukuphonsa ukukhishwa okuyinkimbinkimbi kwama-alloys ahlukahlukene, ikakhulukazi i-superalloy castings.Isibonelo, iphrofayili yangaphandle ehlelekile kanye nokupholisa kwangaphakathi kwe-blade ye-jet injini ngeke kwakhiwe inqubo yomshini.Ukukhiqizwa kobuchwepheshe be-investimenti ye-Investimenti ye-I akukwazi nje ukufeza ukukhiqizwa ngobuningi, ukuqinisekisa ukuvumelana kokusakazwa, kodwa futhi kugweme ukugxiliswa kokucindezeleka kwemigqa ye-blade eyinsalela ngemuva komshini.
2. Ukunemba kwe-dimensional kokusakazwa kwe-investimenti kuphezulu uma kuqhathaniswa, ngokuvamile kufika ku-CT4-6 (CT10~13 yokuphonsa isihlabathi kanye ne-CT5~7 ye-die casting).Yiqiniso, ngenxa yobunzima benqubo yokutshala izimali, kunezici eziningi ezithinta ukunemba kwe-dimensional of castings, njengokuncipha kwezinto zokubumba, ukuguqulwa kwesikhunta sokutshala izimali, ukuguqulwa komugqa wegobolondo lesikhunta ngesikhathi sokubunjwa. Inqubo yokushisisa nokupholisa, ukushwabana kwegolide kanye nokuguqulwa kokusakazwa ngesikhathi senqubo yokuqinisa, ukunemba kobukhulu bokufakwa kwe-investimenti evamile kuphakeme uma kuqhathaniswa, Nokho, ukuvumelana kwayo kusadinga ukuthuthukiswa (ukuvumelana kobukhulu bokubunjwa okuphakathi nendawo nokuphezulu. I-wax yokushisa kufanele ithuthukiswe kakhulu)
3. Uma ucindezela isikhunta sokutshala izimali, isikhunta esinomkhawulo ophezulu we-mold cavity sisetshenziswa.Ngakho-ke, ukuqedwa okungaphezulu kwesikhunta sokutshala izimali nakho kuphakeme kakhulu.Ngaphezu kwalokho, igobolondo lesikhunta lenziwe nge-coating-resistant-resistant coating eyenziwe nge-adhesive high-temperature resistant adhesive and refractory materials, ehlanganiswe nesikhunta sokutshala izimali.Indawo engaphezulu yomgodi wokubumba ethintana nensimbi encibilikisiwe iphezulu.Ngakho-ke, isiphetho esingaphezulu sokubunjwa kwe-investimenti singaphezulu kwalokho kokusakazwa okuvamile, ngokuvamile kufika ku-Ra.1.3.2 μ m.
4. Inzuzo enkulu yokutshala imali ukuthi ngenxa yokuthi ukufakwa kwe-investimenti kunokunemba okuphezulu kobukhulu kanye nokuphela kwendawo, kunganciphisa umsebenzi womshini.Imali encane kuphela yesibonelelo somshini ingashiywa izingxenye ezinezidingo eziphezulu, futhi ngisho nokusakazwa okuthile kungasetshenziswa ngaphandle kokucubungula ngomshini.Kungabonakala ukuthi indlela yokutshala imali ingasindisa amathuluzi amaningi omshini nesikhathi sokucubungula, futhi yonge kakhulu izinto zokusetshenziswa zensimbi.
