Umzimba Wevaluvu Yemoto Yezentengiselwano — GG25 Cast Iron Investment Casting

Uhlolojikelele Lomkhiqizo

I-Commercial Vehicle Air Brake Valve Body iyingxenye ebaluleke kakhulu kwezokuphepha elawula ukugeleza komoya ocindezelwe kumagumbi amabhuleki emalolini athwala kanzima, amabhasi, nama-trailer. Isebenza ezingcindezini zesistimu ezifika kubha engu-10 (145 PSI) ngokuhamba ngebhayisikili okusheshayo phakathi kokugcwaliswa nokukhululwa, lo mzimba wevalvu ufuna ukunemba okukhethekile kobukhulu, ubuqotho obuqinile obuqinile, kanye nokuvumelana kwezinto ezibonakalayo. I-Ningbo Ruican's GG25 grey cast iron investment cast iletha i-geometry yembobo yangaphakathi eyinkimbinkimbi, ukunemba kwesixhumi esibonakalayo, nokuthembeka okuqukethe ukucindezela okudingekayo abakhiqizi besistimu yamabhuleki ezimoto. I-valve ngayinye ihlolwe ukuvuza okungu-100% futhi yaqinisekiswa ngosayizi ku-CMM ukuze kuqinisekiswe ukuthobela imithetho ye-FMVSS 121 kanye ne-ECE R13 yamabhuleki.

Ukucaciswa Kwempahla

Inqubo Yokukhiqiza

1. Umjovo Wephethini ye-wax : Umjovo we-wax onembayo onezikhonkwane ze-wax ezincibilikayo eziphasejini zomoya zangaphakathi
2. Isakhiwo seShell : Igobolondo le-ceramic elingu-7-9 elinejazi eliyinhloko le-zircon ukuze liqedele phezulu
3. I-Dewaxing & Ukudubula : I-Autoclave dewaxing ku-8 bar, igobolondo lidubula ku-950 ° C
4. Ukuthela : GG25 insimbi empunga ethelwe ku-1380-1420°C ngokwelashwa kokujova
5. Ukunciphisa Ukucindezeleka : Ukuhlanganisa ku-550 ° C amahora angu-2 ukuze ukhulule ukucindezeleka okusele
6. I-CNC Machining : Ukujika kwe-CNC nokugaya kwezimbobo ezinentambo (G1/8, G1/4), ubuso obukhuphukayo, kanye ne-piston bore
7. Ukuhlolwa Kwengcindezi : Ukuhlolwa kokuvuza kwe-pneumatic kubha engu-15 (1.5× ingcindezi yokusebenza), ≤ 3 cc/min ukwamukelwa
8. Ukwelapha Okungaphezulu : I-Phosphate coating noma i-e-coating yokuvikela ukugqwala
9. Ukuhlola : Ubukhulu be-CMM, izinhlayiya kazibuthe, ubulukhuni, ukuhlolwa kokuvuza

Izici Eziyinhloko

• I-Complex Internal Porting : Ukutshala izimali nge-wax cores encibilikayo kudala iziteshi zomoya zangaphakathi ezingenakwenzeka ngokusakazwa kwesihlabathi.
• I-Pressure-Tight Integrity : I-100% ihlolwe kubha engu-15 (ingcindezi elinganiselwe engu-1.5×), idlula izidingo ze-FMVSS 121
• Izimbobo Ezinemicu Enembile : Imicu ye-G1/8 kanye ne-G1/4 BSP emshinini wafinyelela ku-6g ukubekezelela ukufakwa okungavuzi
• I-Piston Bore Precision : I-CNC-ifakwe kumshini wokubekezelela i-H7 (± 0.01mm), iqinisekisa ukusebenza kahle kwepiston
• Ukwehliswa Kwengcindezi : Kufakwe ku-550°C ukuze kuqedwe ukucindezeleka okuyinsalela, kuvinjwe ukuhlanekezela emsebenzini
• Ukuthobela Umthetho : Inqubo yokukhiqiza isekela i-PPAP yesitifiketi se-FMVSS 121 kanye ne-ECE R13

Izinkambu Zokusebenza

• Amasistimu wamabhuleki womoya weloli elisindayo (ama-valve adluliswayo, amavalvu akhulula ngokushesha)
• Ibhasi nomqeqeshi wamabhuleki we-pneumatic
• Ama-valve okulawula amabhuleki e-trailer nama-semi-trailer
• Ama-valve okulawula ukumiswa komoya
• Amasistimu omoya ocindezelwe amaningi

Kungani Khetha i-Ningbo Ruican

Iminyaka engu-17+ ka-Ningbo Ruican yobungcweti bokutshala imali ngensimbi empunga, kuhlanganiswe nesitifiketi se-IATF 16949, kusenza abahlinzeki abakhethwayo babakhiqizi bezingxenye zamabhuleki ezimoto. Izindikimba zethu zamavalvu e-GG25 zikhiqizwa ngobuchwepheshe be-wax core obuncibilikayo bejometri yangaphakathi eyinkimbinkimbi, futhi ingxenye ngayinye ihlolwa ukuvuza okungu-100% ku-1.5× yengcindezi yokusebenza. Sihlinzeka ngemibhalo egcwele ye-PPAP Level 3, ukwesekwa kokuthobela i-FMVSS/ECE, nezifundo zamakhono (Cpk ≥ 1.33).
