China OEM custom ductile casting wesi casting deningproses casting investasi lilin ilang. Wesi ulet, sing uga dikenal minangka wesi ulet, wesi nodular, wesi grafit spheroidal, wesi tuang grafit spheroidal, utawa mung wesi SG.Nalika grafit saiki minangka partikel cilik, bunder, lan disebarake kanthi apik, efek lemahe cilik lan wesi tuang kasebut bakal duwe daktilitas sing luwih dhuwur. Jenis wesi tuang iki diarani wesi ductile utawa nodular utawa grafit spheroidal utawa mung wesi SG. Bentuk grafit iki bisa digayuh kanthi nambahake unsur magnesium utawa cerium utawa kombinasi saka rong unsur kasebut menyang wesi tuang cair. Magnesium ditambahake kanthi jumlah 0,07 nganti 0. 10% diikuti karo tambahan ferro-silikon kanggo ningkatake grafitisasi. Sajrone solidifikasi, magnesium mbantu distribusi grafit ing kabeh logam.
Wesi ulet nduweni rasio kekuatan-kanggo-bobot sing luwih apik, kemampuan mesin sing luwih apik lan nilai impact sing luwih dhuwur. Kajaba iku, komponen wesi ductile diprodhuksi dening proses casting ing ngendi kontrol luwih saka wangun komponen bisa ngrambah dibandhingake gulung forging. Mangkono, akeh komponen kayata crank shafts lan connecting rods diprodhuksi biasane dening drop forging tambah akeh diganti dening casting wesi ductile.

Toleransi Casting Bisa Digayuh dening Casting Investasi:
Miturut macem-macem bahan binder sing digunakake kanggo nggawe cangkang, casting investasi bisa dipérang dadi casting silika sol lan casting kaca banyu. Proses pengecoran investasi silika sol nduweni Toleransi Pengecoran Dimensi (DCT) lan Toleransi Pengecoran Geometris (GCT) sing luwih apik tinimbang proses kaca banyu. Nanging, sanajan kanthi proses casting sing padha, Kelas Toleransi bakal beda karo saben alloy cast amarga macem-macem castability. Pengecoran kita pengin ngomong karo sampeyan yen sampeyan duwe panjaluk khusus babagan toleransi sing dibutuhake. Ing ngisor iki minangka kelas toleransi umum sing bisa ditindakake kanthi cara casting silika sol lan proses casting kaca banyu kanthi kapisah:
✔ DCT Grade dening Silica Sol Lost Wax Casting: DCTG4 ~ DCTG6
✔ DCT Grade dening Water Glass Lost Wax Casting: DCTG5 ~ DCTG9
✔ GCT Grade dening Silica Sol Lost Wax Casting: GCTG3 ~ GCTG5
✔ GCT Grade dening Water Glass Lost Wax Casting: GCTG3 ~ GCTG5
