Investment eyahlulayo ikwabizwa ngokuba ilahlekileyo ye-wax okanye i-casting echanekileyo, eyindlela yokwenza isinyithi yokuvelisa iinxalenye ezinokunyamezelana okuqinileyo, imingxunya yangaphakathi enobunzima kunye nemilinganiselo echanekileyo.
Ukutyala imali kutyalo-mali yinkqubo yokuvelisa apho ipatheni ye-wax ifakwe izinto zeceramic. Nje ukuba izinto ze-ceramic ziqiniswe ijiyometri yayo yangaphakathi ithatha imilo yokuphosa. I-wax iyanyibilika kwaye isinyithi esinyibilikisiweyo sigalelwa kwindawo apho bekukho ipateni ye-wax. Isinyithi siqina ngaphakathi komngundo we ceramic emva koko kwaqhekeka isinyithi. Obu buchule bokuvelisa bukwaziwa njengenkqubo ye-wax elahlekileyo. Ukutyalwa kotyalo mali kuphuhlisiwe ukuthandana kumawakawaka eminyaka eyadlulayo kwaye kungalandela iingcambu zawo ukubuyela kwi-Egypt yamandulo nase China.
Ezona nkqubo ziphambili zezi zilandelayo:
Ukudalwa kwepateni -Iipateni ze-wax zihlala zinenaliti ebunjiweyo kwisinyithi kwaye zenziwa njengesiqwenga esinye. Iicres zingasetyenziselwa ukwenza naziphi na izinto zangaphakathi kwipateni. Eziliqela zezi patheni ziqhotyoshelwe kwinkqubo ye-wax gating esembindini (i-sprue, iimbaleki kunye ne-risers), ukwenza indibano efana nomthi. Inkqubo yesango yenza amajelo apho isinyithi esinyibilikileyo esiya kungena kumngxunya wokubumba.
Ukudalwa komngundo - Lo "mthi wepateni" uthi nkxu kuludwe lwamaqhekeza e-ceramic acolekileyo, athiwe wambu ngamasuntswana erhabaxa, emva koko omiswe ukuze enze iqokobhe le-ceramic elijikeleze iipateni kunye nenkqubo yokubamba. Le nkqubo iyaphindaphindwa ide iqokobhe libe shushu ngokwaneleyo ukumelana nesinyithi esinyibilikileyo esiya kudibana nayo. Iqokobhe lifakwa kwi-oveni lize inyibilike inyibilikiswe kushiyeke iqokobhe le-ceramic elingenanto elisebenza njengombumba omnye, yiyo loo nto igama "ukulahleka kwe-wax".
Ukuthulula -Umbumbulu ushushu ngaphambili kwiziko ukuya kuthi ga kwi-1000 ° C (1832 ° F) kwaye isinyithi esityhidiweyo sigalelwa kwilali ukuya kwinkqubo yokubamba yomngundo, igcwalise isikhunta. Ukugalelwa kufezekiswa ngesandla phantsi kwamandla omxhuzulane, kodwa ezinye iindlela ezinje ngomshini okanye uxinzelelo ngamanye amaxesha ziyasetyenziswa.
Ukupholisa -Emva kokuba ukungunda kuzalisiwe, isinyithi esinyibilikisiweyo siyavunyelwa ukuba sipholile kwaye siqine kwimilo yokuphosa kokugqibela. Ixesha lokupholisa lixhomekeke kubukhulu benxalenye, ubukhulu besikhunta, kunye nezinto ezisetyenzisiweyo.
Ukulahla ukususwa -Emva kokuba isinyithi esityhidiweyo sele selehlile, ukungunda kunokwaphulwa kwaye kususwe ukulahlwa. Ukubumba kwe-ceramic kuqhekezwa kusetyenziswa iijets zamanzi, kodwa zikho ezinye iindlela ezikhoyo. Nje ukuba zisuswe, iinxalenye ezo zahlulwe kwinkqubo yokugaywa ngosarha okanye ngokuqhaqha okubandayo (kusetyenziswa initrogen engamanzi).
Ukugqiba Amaxesha ngamaxesha, ukugqibezela imisebenzi enjengokuguba okanye ukubamba isanti kusetyenziselwa ukuhambisa inxenye emasangweni. Unyango lobushushu ngamanye amaxesha lusetyenziselwa ukwenza nzima indawo yokugqibela.
