The ductile cast iron castings e hlahisoang ke resin e tlotsitsoeng ka lehlabathe le tsoang k'hamphaning ea China e nang leMechine ea CNCle lits'ebeletso tsa tlhahlobo.
Sehlahisoa sa lehlabathe se koahetsoeng ka resin se sebelisoa haholo ho hlahisali-castings tse tloaelehilengka ditlhoko tse phahameng hofetamokhoa oa ho lahla lehlabathe le letala. Pele o etsa hlobo le mokokotlo, lehlabathe le koahetsoeng le koahetsoe ka filimi e tiileng ea resin holim'a likaroloana tsa lehlabathe. Lehlabathe le koahetsoeng le boetse le bitsoa lehlabathe la shell (core). Mokhoa oa thekenoloji ke oa ho kopanya sefate sa phenolic se phofshoana le lehlabathe le tala le ho tiisa ha se futhumatsoa. E ntlafalitsoe ho ba lehlabathe le koahetsoeng ka ho sebelisa thermoplastic phenolic resin mmoho le latent folisang (joaloka urotropine) le lubricant (joalo ka calcium stearate) ka mokhoa o itseng oa ho roala. Ha lehlabathe le koahetsoeng le futhumatsoa, resin e koahetsoeng ka holim'a likaroloana tsa lehlabathe ea qhibiliha. Tlas'a ketso ea sehlopha sa methylene se qhibilihisitsoeng ke Maltropine, resin e qhibilihisitsoeng e fetoha ka potlako ho tloha mohahong o lekaneng ho ea ho sebopeho sa 'mele o sa tsitsang e le hore lehlabathe le koahetsoeng le tiee le ho thehoa. Ho phaella ho mofuta o akaretsang o omileng oa granular oa lehlabathe le koahetsoeng, ho boetse ho na le lehlabathe le nang le metsi le li-viscous.
Resin e koahetsoeng ka lehlabathe la ho lahla ho na le litšobotsi tse latelang
1) E na le ts'ebetso e nepahetseng ea matla. E ka fihlela litlhoko tsa lehlabathe la mokokotlo oa khetla ea matla a holimo, lehlabathe la lebokoso le chesang le nang le matla a mahareng, le lehlabathe la alloy le non-ferrous alloy e matla a tlase.
2) Mokelikeli o motle haholo, sebopeho se setle sa mokokotlo oa lehlabathe le kemiso e hlakileng, e ka hlahisang li-cores tsa lehlabathe tse rarahaneng ka ho fetisisa, tse kang li-cores tsa lehlabathe la baki ea metsi tse kang lihlooho tsa li-cylinder le lihlopha tsa mochine.
3) Boleng ba bokaholimo ba mokokotlo oa lehlabathe bo botle, bo kopane ebile ha bo lokolohe. Esita le haeba ho sebelisoa ho roala ho fokolang kapa ho se na letho, boleng bo holimo ba holim'a metsi bo ka fumanoa. The dimensional ho nepahala ha castings ka fihla CT7-CT8, 'me holim'a roughness Ra ka fihla ho 6.3-12.5μm.
4) Collapsibility e ntle, e thusang ho hloekisa le ho ntlafatsa ts'ebetso ea sehlahisoa
5) Motsoako oa lehlabathe ha o bonolo ho monya mongobo, 'me matla a ho boloka nako e telele ha a bonolo ho fokotseha, a loketseng ho boloka, ho tsamaisa le ho sebelisoa.
Mekhoa ea tlhahiso ea resin coated sand hlobo (core) making forho etsa likhetla:
1. Mokhoa oa mantlha oa ho etsa hlobo ea lehlabathe e koahetsoeng (konokono) ke: flip kapa blow sand → crust → lehlabathe lahla → thatafatsa → konokono ( hlobo) joalo-joalo.
1) Phetla lehlabathe kapa u butsoe. Ke hore, lehlabathe le koahetsoeng le tšeloa holim'a hlobo ea khetla kapa le phunyeletsoa ka har'a lebokose la mantlha ho etsa khetla kapa khetla ea mantlha.
2) Ho koaheloa. Botenya ba lera la khetla bo laoloa ka ho fetola mocheso oa mocheso le nako ea ho tšoara.
3) Ho tsoa ha lehlabathe. Eketsa hlobo le lebokose la mantlha ho etsa hore lehlabathe le koahetsoeng le sa sebetsanoang le oele holim'a lekhapetla le futhumetseng, 'me le le bokelle hore le sebelisoe hape. E le ho etsa hore ho be bonolo ho tlosa lehlabathe le koahetsoeng le sa qhibilihang, haeba ho hlokahala, mokhoa oa mechine oa ho sisinyeha ka morao le pele o ka amoheloa.
4) Ho thatafatsa. Boemong ba ho futhumatsa, e le ho etsa hore botenya ba khetla bo be bo lekanang, bo etse hore bo kopane le holim'a khetla e futhumetseng ka nako e itseng ho thatafatsa.
5) Nka mantlha. Ntša sebopeho se thata sa khetla le mokokotlo oa khetla ka har'a hlobo le lebokose la mantlha.
