Lachin OEM repòtaj ductile kas an fè castings papèdi sir envèstisman pwosesis Association. Ductile fè, ki se ke yo rele tou ducitle kas fè, fè nodilè, fè grafit esferoidal, fè jete grafit esferoidal, oswa jis SG fè pou kout.Lè grafit prezan kòm patikil piti, wonn, ak byen distribye, efè febli li yo piti epi jete sa yo ta gen pi wo duktilite. Sa a se kalite fè jete yo rele ductile oswa nodilè fè oswa grafit esferoidal oswa tou senpleman SG fè. Fòm sa a nan grafit ka reyalize lè w ajoute mayezyòm elemantè oswa seryòm oswa yon konbinezon de eleman yo nan fè fonn jete. Manyezyòm ajoute nan kantite 0.07 a 0. 10% ki te swiv pa adisyon Fero-Silisyòm pou ankouraje grafitizasyon. Pandan solidifikasyon, mayezyòm ede nan distribisyon an nan grafit nan tout metal la.
Ductile fè gen pi bon rapò fòs-a-pwa, pi bon machinability ak pi wo valè enpak. Anplis, konpozan yo fè duktil yo pwodui pa pwosesis Distribisyon kote yo ka reyalize pi bon kontwòl sou fòm eleman konpare ak forge gout. Se konsa, anpil yon eleman tankou manivelle aks ak branch bwa ki fabrike anjeneral pa gout Forge se de pli zan pli ranplase pa moule fè duktil.

Kapasite nanFondasyon Distribisyon Envestisman:
• Max Size: 1,000 mm × 800 mm × 500 mm
• Ranje pwa: 0.5 kg - 100 kg
• Kapasite anyèl: 2,000 tòn
• Materyèl Kolèj pou Konstriksyon Shell: Sol Silica, vè dlo ak melanj yo.

Distribisyon Envestisman ta ka rive jwenn tolerans nan Distribisyon:
Dapre diferan materyèl lyan yo itilize pou fè koki a, Distribisyon envestisman an ta ka divize an Distribisyon Sol silica ak Distribisyon vè dlo. Pwosesis Distribisyon envèstisman silica Sol la gen pi bon Tolerans Distribisyon Dimansyon (DCT) ak Tolerans Distribisyon Jeyometrik (GCT) pase pwosesis vè dlo. Sepandan, menm pa menm pwosesis Distribisyon, Klas Tolerans yo pral diferan de chak alyaj jete akòz divès kalite castability yo. Fondi nou an ta renmen pale avèk ou si ou gen demann espesyal sou tolerans yo mande yo. Isit la nan sa ki annapre yo se klas tolerans jeneral nou ta ka rive jwenn tou de pa depoze sol silica ak pwosesis depoze vè dlo separeman:
✔ DCT Klas pa Silica Sol Lost Wax Casting: DCTG4 ~ DCTG6
✔ DCT Klas pa Distribisyon sir pèdi vè dlo: DCTG5 ~ DCTG9
✔ Klas GCT pa Silica Sol Lost Wax Casting: GCTG3 ~ GCTG5
✔ GCT Klas pa Distribisyon sir ki pèdi vè dlo: GCTG3 ~ GCTG5
