Inkqubo ephambili yokufakwa kwe-Investment casting ibandakanya onke amanyathelo abalulekileyo, ukusuka ekulungisweni kwezinto eziluhlaza ukuya ekuqulunqweni kokugqibela kwe-precision castings. La manyathelo adibene kwaye asebenzisana, eqinisekisa umgangatho ophezulu kunye nokuchaneka kweemveliso ze-precision castings.
Ukulungiselela iPateni yeMold kunye neWax
Uyilo lwedijithali lusebenza njengendawo yokuqala yokulungiselela ipateni yesikhunta kunye newax, lusebenzisa ubuchwepheshe obuphambili beCAD. Iinjineli zakha ngokuchanekileyo iimodeli zesikhunta ezinemilinganiselo emithathu. Emva koko, ezi modeli ziguqulwa zibe yimfumba ebonakalayo ngezixhobo zomatshini ezichanekileyo, ziqinisekisa ukuba ubukhulu bazo kunye nemilo zihambelana ngokuchanekileyo noyilo. Emva kokuba umatshini womatshini ugqityiwe, inkqubo yokwenza ipateni yewax iyaqala. Apha, izinto zewax ezinyibilikisiweyo zifakwa kwisikhunta, kwaye xa zipholile, kufunyanwa ipateni yewax ehambelana nokufakwa kokugqibela.
Ukwakhiwa kweShell
Inkqubo yokwenza isikhunta seqokobhe iyinkimbinkimbi. Ekuqaleni, umaleko we-slurry ufakwa kumphezulu wemodeli ye-wax, kulandele ukufafazwa kwezinto ezingafunekiyo ezifana nesanti ye-zircon okanye izinto ezisekwe kwi-mullite, kuze kulandele inkqubo yokomisa. Olu landelelwano kufuneka luphindwe amaxesha amaninzi ukuze kwenziwe iqokobhe eliqinileyo elinobukhulu obaneleyo, ukuqinisekisa ukuba linokumelana namaqondo obushushu aphezulu kunye nefuthe lesinyithi esinyibilikisiweyo ngexesha lenkqubo yokubumba.
Ukunyibilikisa nokuphosa
Ukunyibilika nokuphosa izinto ngamanyathelo abalulekileyo ekwakhiweni kwezinto eziphoswayo. Ekuqaleni, imodeli yewax isuswa ngokufudumeza, ishiya umngxuma weqokobhe lesikhunta. Emva koko, iqokobhe lesikhunta liphathwa ngokucoca ukuze lomeleze ukumelana nobushushu obuphezulu. Emva koko, isinyithi siyanyibilika ukuya kubushushu obufanelekileyo size sigalelwe kumngxuma weqokobhe lesikhunta kusetyenziswa ubuchwepheshe bokuphosa nge-vacuum. Emva kokupholisa nokuqina, kufunyanwa isinyithi esihlangabezana neemfuno.
Ukucutshungulwa emva
Inqanaba emva kokucubungula liquka amanyathelo aliqela, kuquka ukushukuma, ukusika, ukugqiba, kunye nokuhlola. Ukushukuma kusebenza ekususeni igobolondo lesikhunta, ukusika kwahlula ukushukuma kwinkqubo yokugada, ukugqiba kuphucula ukuchaneka kobukhulu kunye nokugqitywa komphezulu wokushukuma, kwaye ukuhlolwa kuqinisekisa ukuba ukushukuma kuyahlangabezana neemfuno zoyilo kunye nemigangatho yomgangatho.
