Musiyano pakati pesimbi castings uye iron castings:
Simbi nesimbi isimbi dzakati wandei.Kuti zvizadzise zvinodiwa zvekushandisa zvenzvimbo dzakasiyana, vagadziri vanozozvigadzirisa zvakasiyana, uye simbi yakakandwa uye simbi yakakandwa inogadzirwa.
1. Kupenya kwakasiyana.Simbi yakakandwa inopenya zvakanyanya, ukuwo simbi yekukandwa ipfumbu uye yakasviba.Pakati pavo, grey iron uye ductile iron in cast iron ine kupenya kwakasiyana, yekutanga yakasviba kupfuura yekupedzisira.
2. Zvimedu zvakasiyana.Kunyangwe simbi yakakandwa igrey iron kana ductile iron, zvidimbu zvinogona kuonekwa, uye zvidimbu zvegrey iron zvakakura;simbi yakakandwa yakagadzirwa nenheyo yakaoma kwazvo, uye zvidimbu pairi kazhinji hazvionekwe nemaziso.
3. Inzwi rakasiyana.Steel castings ichaita "chaiyo" ruzha painobonderana, asi simbi yakakandwa yakasiyana.
4. Kucheka gasi kwakasiyana.Iyo yepamusoro yesimbi yakakandwa yakashata, ine yakakura riser uye gedhi nzvimbo, iyo inoda kucheka gasi kuti ibvise, asi gasi kutema hakushandi pasimbi yakakandwa.
5. Kusiyana kwakaoma.Kuoma kwesimbi yakakandwa zvishoma zvishoma, zvikamu zvakatetepa-zvakakomberedzwa zvinogona kukotama pa 20-30 degrees, uye grey iron haina kuoma;kuoma kwesimbi yakagadzirwa nenheyo iri pedyo neyo yesimbi yesimbi, iyo iri nani kupfuura iyo yesimbi yakagadzirwa.
