OEM Custom Grey Iron Casting
Tlhaloso ea Sehlahisoa
Grey iron, kapa grey cast iron, ke mofuta oa tšepe oa tšepe o nang le graphite microstructure.Re bitsa mofuta ona oa tšepe e bohlooho ka lebaka la 'mala o moputsoa oa ho robeha.Bakeng sa graphite e tlotsang sehiloeng le ho pshatla li-chips, tšepe e bohlooho ke motsoako o tloaelehileng oa cast ka lebaka la theko ea eona e batlang e le tlaase le machinability e ntle.Ntle le moo, hobane graphite flakes self lubricate, e boetse e na le galling e ntle le ho se sebetse hantle.
Grey iron e boetse e na le shrinkage e fokolang ea ho tiea ho feta litšepe tse ling ka lebaka la microstructure ea graphite.Ha e ntse e lahla, karolo ea silicon e ka khothaletsa khanyetso e ntle ea kutu le ho eketsa mokelikeli ha o lahla.Ka kakaretso tšepe e putsoa e nkoa e le bonolo ho e cheseletsa.Ha ho bapisoa le tse linglitšepe tsa tšepe, tšepe e bohlooho e na le matla a tlaase a ho tsitsa le ductility;ke ka lebaka leo tšusumetso le ts'oaetso ea ts'oaetso ea mofuta ona oa thepa e batlang e le sieo.

Setsing sa rona, re ka etsa li-castings tsa tšepe tse bohlooho ka mefuta e 'meli e ka tlase:
Ho Lahla Foam e Lahlehileng: Eona feelaho kenya cheletets'ebetso ea likarolo tsa tšepe tse entsoeng ka tšepe, e nang le melemo e mengata ea ho hlahisa li-castings tse nyane tsa tšepe tse bohlooho, joalo ka litšenyehelo tse bolokiloeng tsa hlobo, ho khutsufatsa potoloho ea tlhahiso le ho ntlafatsa katleho ea tlhahiso.Ka ts'ebetso ea ho lahlela foam e lahlehileng, re ka thusa bareki ba rona ho fumana lihlahisoa tse nepahetseng haholo tse nang le pheletso e ntle haholo, mme ts'ebetso e nyane ea machining e tla etsoa.
Resin Sand Casting: Mokhoa o ka sehloohong oa ho lahla lehlabathe bakeng sa li-castings tse nyenyane le tse mahareng.Ha ho bapisoa le lits'ebetso tse ling tsa ho lahla lehlabathe, ho lahla lehlabathe la resin ke mokhoa o nepahetseng oa ho lahla o haufi le ho etsa matsete.Joalo ka ho tiea ho hotle ha lehlabathe la resin le matla a phahameng a hlobo ea lehlabathe nakong ea ha e qala, re ne re ka khona ho felisa lekhalo le honyehang, bofokoli ba ho honyela ha tšepe e putsoa.
