I-ductile casting iron castings eveliswa yi-resin egqunywe isanti egayiweyo evela kwinkampani yaseChinaCNC Machiningkunye neenkonzo zovavanyo.
I-resin egqunywe ngesanti yokuphosa isetyenziselwa ngokubanzi ukuvelisaiicastings eziqhelekileyongeemfuno eziphezulu kuneinkqubo yokugalela isanti eluhlaza. Ngaphambi kokwenza i-mold kunye ne-core, isanti edibeneyo ihlanganiswe nefilimu eqinile ye-resin phezu kweengqungquthela zesanti. Isanti egqunyiweyo ikwabizwa ngokuba yisanti yeqokobhe (core) sand. Inkqubo yethekhnoloji kukuxuba ngomatshini umthi wephenolic owenziwe ngumgubo kunye nesanti ekrwada kwaye uqine xa ushushu. Iphuhliswe yaba yintlabathi egqunyiweyo ngokusebenzisa i-thermoplastic phenolic resin kunye ne-latent curing agent (efana ne-urotropine) kunye ne-lubricant (efana ne-calcium stearate) ngenkqubo ethile yokwaleka. Xa isanti egqunyiweyo ishushu, i-resin egqunywe phezu kwendawo yentlabathi iyanyibilika. Ngaphantsi kwesenzo seqela le-methylene elichithwa yi-Maltropine, i-resin etyhidiweyo iguquka ngokukhawuleza ukusuka kwisakhiwo somgca ukuya kwisakhiwo somzimba esingenasiphelo ukwenzela ukuba isanti edibeneyo iqiniswe kwaye yenziwe. Ukongeza kwindlela eyomileyo ye-granular yesanti egqunyiweyo, kukho isanti emanzi kunye ne-viscous egqunywe.
I-resin efakwe kwisanti yokugalela inezi mpawu zilandelayo
1) Inokusebenza okufanelekileyo kwamandla. Inokuhlangabezana neemfuno zesanti engundoqo yeqokobhe eliphezulu, isanti yebhokisi eshushu ephakathi nendawo, kunye nesanti yealloy engenawo amandla asezantsi.
I-2) I-fluidity egqwesileyo, ukubunjwa kakuhle kwengundoqo yesanti kunye nolwandlalo olucacileyo, olunokuvelisa i-sand cores enzima kakhulu, njenge-sand cores yebhantshi yamanzi njengeentloko ze-cylinder kunye nemizimba yomatshini.
3) Umgangatho ophezulu wesiseko sesanti ulungile, uhlangene kwaye awukhululekanga. Nokuba kuthe kwafakwa i-coat encinci okanye akukho nto, umgangatho ongcono we-castings unokufumaneka. Ukuchaneka kwe-dimensional of castings kunokufikelela kwi-CT7-CT8, kunye noburhabaxa bomhlaba uRa unokufikelela kwi-6.3-12.5μm.
4) I-collapsibility efanelekileyo, ehambelana nokuphosa ukucoca kunye nokuphucula ukusebenza kwemveliso
5) Undoqo wesanti akulula ukufunxa umswakama, kwaye amandla okugcinwa kwexesha elide akulula ukunciphisa, okulungele ukugcina, ukuthutha kunye nokusetyenziswa.
Ukwenziwa kweenkqubo zokwenziwa kwe-resin coated sand mold (core) ukwenzaukubunjwa kweqokobhe:
1. Inkqubo esisiseko yokwenziwa kokungunda kwesanti egqunyiweyo (undoqo) kukuba: flip okanye ukuvuthela isanti→uqweqwe →ukukhukula kwesanti→ukuqina→undoqo (umngundo) njalo njalo.
1) Phendulela okanye uvuthele isanti. Oko kukuthi, isanti egqunyiweyo igalelwa kwigobolondo lokungunda okanye ivuthelwe kwibhokisi engundoqo ukwenza iqokobhe okanye undoqo weqokobhe.
2) I-Encrustation. Ubunzima bomgca wegobolondo bulawulwa ngokulungelelanisa ubushushu bokufudumala kunye nexesha lokubamba.
3) Ukukhutshwa kwesanti. Ukutshekisa ukungunda kunye nebhokisi engundoqo ukwenza isanti engaphendulwanga egqunyiweyo iwe kumphezulu weqokobhe elishushu, kwaye uyiqokelele ukuze iphinde isetyenziswe. Ukuze kube lula ukususa isanti enganyibilikisiweyo egqunyiweyo, ukuba kuyimfuneko, indlela yomatshini yokugubha ngasemva naphambili ingamkelwa.
4) Ukuqina. Kwimeko yokufudumala, ukwenzela ukuba ubuninzi begobolondo bufanane ngakumbi, yenze ukuba udibanise nomphezulu wegobolondo evuthayo ngaphakathi kwexesha elithile ukuqhubela phambili ukuqina.
5) Thatha ingundoqo. Thatha iqokobhe eliqinileyo imilo kunye nondoqo weqokobhe ngaphandle komngundo kunye nebhokisi engundoqo.

✔ Ukwenza i-Sand Mold eqatywe kwangaphambili. Emva kokufaka iipateni zetsimbi kumatshini wokubumba, isanti ye-resin efakwe ngaphambili iya kudutshulwa kwiipatheni, kwaye emva kokufudumeza, i-resin yokugqoka iya kunyibilika, emva koko iimbumba zesanti zibe yigobolondo yesanti eqinile kunye neentsimbi.
✔ Ukunyibilikisa iCast Metal. Ukusebenzisa i-furnaces induction, izinto ziya kunyibilika zibe yi-liquid, emva koko ukubunjwa kweekhemikhali zesinyithi se-liquid kufuneka kuhlalutywe ukuze kuhambelane namanani afunekayo kunye neepesenti.
✔ Ukugalela isinyithi. Xa isinyithi esinyibilikisiweyo sihlangabezana neemfuno, ngoko ziya kugalelwa kwi-shell shell molds. Ngokusekwe kubalinganiswa abahlukeneyo boyilo lokubunjwa, ukubumba iqokobhe kuya kungcwatywa kwisanti eluhlaza okanye kuhlanganiswe ngamaleko.
✔ Ukudutyulwa kokuqhunyiswa, ukuSila kunye nokuCoca. Emva kokupholisa kunye nokuqiniswa kwee-castings, ukukhuphuka, amasango okanye isinyithi esongezelelweyo kufuneka sinqunywe kwaye sisuswe. Emva koko iintsimbi ziyakucocwa ngezixhobo zokukrola esantini okanye ngoomatshini abadubulayo. Emva kokugaya intloko yesango kunye nemigca yokuqhawula, iinxalenye ezigqityiweyo zokuphosa ziza kuza, zilindele iinkqubo ezingaphezulu xa zifuneka.
