Ukufakwa kwe-investimenti (i-wax casting elahlekile) kuyindlela yokunemba kwenqubo engakhiqiza imininingwane eyinkimbinkimbi yomumo we-net-net isebenzisa ukuphindaphinda kwamaphethini we-wax. Ukutshala imali noma i-wax elahlekile kuyinqubo yokwenza insimbi ngokuvamile esebenzisa iphethini ye-wax ezungezwe igobolondo le-ceramic ukwenza isikhunta se-ceramic. Lapho igobolondo loma, ingcina iyancibilika, kusale isikhunta kuphela. Khona-ke ingxenye yokuphonsa ikhiwa ngokuthululela insimbi encibilikisiwe esikhunjini se-ceramic.
Ngokuvumelana nezihlanganisi ezihlukene zokwakha amagobolondo, ukufakwa kwe-investimenti kungahlukaniswa ngokufaka utshalomali kwe-silica sol binder, ukusakaza kwe-investment binder yengilazi yamanzi kanye nokufaka utshalomali ngezingxube zakhona njengezinto ezihlanganisayo.
Ingilazi yamanzi, eyaziwa nangokuthi i-Sodium Silicate, iwuhlobo lwe-silicate yensimbi ye-alkali encibilikayo, eyingilazi esesimweni esiqinile futhi yakha isixazululo sengilazi yamanzi lapho incibilika emanzini. Ngokomehluko wezinsimbi ze-alkali eziqukethwe, kunezinhlobo ezimbili zengilazi yamanzi e-potassium nengilazi yamanzi e-soda. Lokhu kokugcina kuncibilika kalula emanzini, kuqukethe ukungcola okuncane, futhi kunokusebenza okuzinzile. Ngakho-ke, ingilazi yamanzi yokutshala imali ingilazi yamanzi ye-sodium, okuyi-Na20 · mSiO2, Isixazululo se-colloidal esobala noma esiguquguqukayo esakhiwe ngemva kwe-hydrolysis. Izingxenye zamakhemikhali eziyinhloko zengilazi yamanzi yi-silicon oxide ne-sodium oxide. Ngaphezu kwalokho, iqukethe nenani elincane lokungcola. Ingilazi yamanzi ayiyona inhlanganisela eyodwa, kodwa ingxube yezinhlanganisela eziningi.
Enqubweni yokutshala imali, i-binder yengilazi yamanzi kanye ne-coating inokusebenza okuzinzile, intengo ephansi, umjikelezo omfushane wokwenza amagobolondo kanye nokusetshenziswa okulula. Inqubo yokwenza igobolondo lengilazi yamanzi ifaneleka ukukhiqizwa kokutshala imali okufana nensimbi ye-carbon, insimbi ye-low-alloy, i-cast iron, ithusi ne-aluminium alloys edinga ikhwalithi encane yendawo.
Custom ingxubevange steel casting izingxenye ezisele byulahlekelwe inqubo yokutshala imali ye-waxngengilazi yamanzi (isixazululo esinamanzi se-sodium silicate) njengezinto ezihlanganisayo zokwenza amagobolondo. Ikhwalithi yokwenza amagobolondo ithonya ukunemba kokulingisa kokugcina ngakho-ke kuyinqubo ebaluleke kakhulu ngesikhathi sokutshala imali. Izinga legobolondo lihlobene ngokuqondile nobulukhuni kanye nokubekezelelana kobukhulu bokubunjwa kokugcina. Ngakho-ke, kuwumsebenzi obalulekile we-investment casting Foundry ukukhetha indlela yokukhiqiza efanelekile yegobolondo lesikhunta.Ngokwezinto zokunamathisela ezihlukene noma izinto zokuhlanganisa zokwenza igobolondo lesikhunta, isikhunta sokutshala imali singahlukaniswa sibe amagobolondo okunamathela engilazini yamanzi, amagobolondo okunamathisela e-silica sol, amagobolondo okunamathisela e-ethyl silicate kanye namagobolondo ayinhlanganisela e-ethyl silicate-silica sol. Lezi zindlela zokumodela ziyizindlela ezisetshenziswa kakhulu ekulingiseni utshalomali.
Igobolondo le-Mold nge-Water Glass (isixazululo esinamanzi se-sodium silicate)
Ukufakwa kwe-investimenti okukhiqizwe igobolondo lengilazi yamanzi kunobunzima obuphezulu obuphezulu, ukunemba kobukhulu obuphansi, umjikelezo omfishane wokwenza amagobolondo kanye nenani eliphansi. Le nqubo isetshenziswa kabanzi ekukhipheni i-carbon steel, i-low alloy steel, i-aluminium alloy ne-alloy yethusi.
Igobolondo Lesikhunta nge-Silica Sol Shell (ukuhlakazwa kwezinhlayiya ze-silica zesikali se-nano-scale emanzini noma kwi-solvent)
I-silica sol investment cast inobulukhuni obuphansi, ukunemba okuphezulu kobukhulu, kanye nomjikelezo omude wokwenza amagobolondo. Le nqubo isetshenziswa kakhulu ekubunjweni kwe-alloy ekwazi ukumelana nokushisa okuphezulu, ukusakaza kwensimbi ukumelana nokushisa, ukusakaza kwensimbi engagqwali, ukukhishwa kwensimbi ye-carbon steel, ukukhishwa kwe-alloy ephansi, ukubunjwa kwe-aluminium alloy kanye nokusakazwa kwe-alloy yethusi.
Igobolondo Lesikhunta ngu-Ethyl Silicate Shell
Ekubunjweni kokutshalwa kwezimali, ukulingwa okwenziwa kusetshenziswa i-ethyl silicate njengesibophezelo ukwenza igobolondo libe nokuhwalala okuphansi, ukunemba kobukhulu obuphezulu, kanye nomjikelezo omude wokwenza amagobolondo. Le nqubo isetshenziswa kakhulu ekubunjweni kwe-alloy ukumelana nokushisa, ukubunjwa kwensimbi engangeni ekushiseni, ukubunjwa kwensimbi engagqwali, ukukhishwa kwensimbi ye-carbon steel, ukukhishwa kwe-alloy ephansi, ukubunjwa kwe-aluminium alloy kanye nokusakazwa kwe-alloy yethusi.
Insimbi ye-Carbon, insimbi ephansi ye-alloy, nezinsimbi zensimbi zamathuluzi zisetshenziswa ezininganaizicelo zezimbonikanye nezindawo. Ngamamaki azo amaningi, insimbi nama-alloys azo kungenziwa ukushisa ukuze kuthuthukiswe isivuno sawo namandla aqinile; futhi, lungisa ubulukhuni noma i-ductility ezidingweni zohlelo lukanjiniyela noma izici zomshini ezifiselekayo.
Ukufakwa kwe-investimenti yensimbi ye-alloy engagugi yizingxenye zokusakaza ezikhiqizwa inqubo yokusakazwa kwe-wax elahlekile eyenziwe ngensimbi engagugi. Kwa-RMC Foundry, izinqubo eziyinhloko zokuphonsa isihlabathi esingazisebenzisa ekwenzeni insimbi engagugiyo i-alloy casting, ukufakwa kwesihlabathi esimbozwe inhlaka, ukubunjwa kwesihlabathi esingabhaki, ukuphonswa kwegwebu okulahlekile, ukufakwa kwe-vacuum nokufaka utshalomali. Ukwelashwa kokushisa, ukwelashwa kwendawo kanye nemishini ye-CNC nakho kuyatholakala embonini yethu ngokwemidwebo kanye nezidingo zakho.
Phakathi kwezinhlobonhlobo eziningi ze-casting alloys, insimbi eyinsimbi engagqoki iyinsimbi esetshenziswa kabanzi. Insimbi esakazwayo ekwazi ukumelana nokugqokwa ithuthukisa ikakhulukazi ukumelana nokuguga kwezinsimbi zensimbi ngokwengeza okuqukethwe okuhlukile kwezakhi zengxubevange, njenge-manganese, i-chromium, ikhabhoni, njll., kungxubevange. Ngesikhathi esifanayo, ukumelana nokugqoka kwe-castings yensimbi engaguquki nakho kuncike endleleni yokwelashwa kokushisa esetshenziswa yi-Foundry kanye nesakhiwo sokuphonsa.
Ngokwezici zokugqokwa ezihlukene, ukugqokwa kwensimbi kungahlukaniswa kube ukuguguleka, ukunamathela okunamathelayo, ukukhathala, ukugqwala nokugqokwa okukhathazayo. Izinsimbi zensimbi ezingagqoki zisetshenziswa kakhulu emikhakheni yezimboni enezimo zokusebenza eziyinkimbinkimbi kanye nezidingo eziphezulu zokusebenza kwemishini, njengezimayini, i-metallurgy, ukwakhiwa, amandla, i-petrochemical, ukongiwa kwamanzi, izimboni zezolimo nezokuthutha. Ama-casting ensimbi angagugi asetshenziswa kakhulu ezimeni zokuhuzuka ezinomthwalo othize womthelela, njengezisetshenziswa zokugaya, ama-excavators, ama-crusher, ogandaganda, njll.
