Izingxenye ezisele ze-OEM zase-China ze-OEM yezimoto ezithwala impahla zikaloliwe ze-Cr-Mo ingxubevange yensimbi ephathwa ukushisa, ukwelashwa kwendawo kanyeIsevisi yemishini ye-CNC.
I-Vacuum Casting ibizwa nangokuthi i-Negative Pressure Sealed Casting, i-Reduced Pressure Casting nomaV Inqubo yokusakaza. Ukukhishwa kwengcindezi ye-vacuum kudinga ukusetshenziswa kwemishini yokukhipha umoya ukuze kukhishwe umoya ngaphakathi kwesikhunta sokuphonsa, bese usebenzisa umehluko wengcindezi phakathi kwangaphakathi nangaphandle kwesikhunta ukumboza ifilimu yepulasitiki eshisayo kuphethini nesifanekiso. Isikhunta esibunjiwe sizoba namandla ngokwanele ukumelana nensimbi encibilikisiwe ngesikhathi sokubunjwa. Ngemuva kokuthola isikhunta se-vacuum, gcwalisa ibhokisi lesihlabathi ngesihlabathi esomile ngaphandle kwe-binder, bese uvala indawo engaphezulu yesikhunta sesihlabathi ngefilimu yepulasitiki, kulandelwa i-vacuum ukwenza isihlabathi siqine futhi siqine. Ngemuva kwalokho, susa isikhunta, ubeke ama-sand cores, uvale isikhunta ukuze wenze konke kukulungele ukuthululwa. Ekugcineni, ukubunjwa kutholakala ngemva kokuba insimbi encibilikisiwe ipholile futhi iqina.
| Ukusakaza Kwegwebu Elilahlekile vs Ukusakaza Ngevacuum | ||
| Into | Ukusakaza Kwegwebu Elilahlekile | I-Vacuum Casting |
| Ukusakaza Okufanelekile | Ama-casting amancane naphakathi anezimbotshana eziyinkimbinkimbi, njengebhulokhi yenjini, ikhava yenjini | Ukulingisa okumaphakathi nokukhulu okunezimbotshana ezimbalwa noma ezingenawo nhlobo, njengama-cast iron counterweights, i-cast steel axle housings |
| Amaphethini namaPlate | Amaphethini we-Foam akhiwe ngama-moldings | Isifanekiso esinebhokisi lokumunca |
| Ibhokisi lesihlabathi | Phansi noma izinhlangothi ezinhlanu khipha amandla | Izinhlangothi ezine zikhipha i-exhaust noma ipayipi yokukhipha |
| Ifilimu Yepulasitiki | Isembozo esiphezulu sivalwe ngamafilimu epulasitiki | Zonke izinhlangothi zazo zombili izingcezu zebhokisi lesihlabathi zivaliwe ngamafilimu epulasitiki |
| Izinto Zokumboza | Upende osuselwe emanzini onoqweqwe oluwugqinsi | Upende olusekelwe otshwaleni olunoqweqwe oluncane |
| Isihlabathi sokubumba | Isihlabathi esomile esimahhadlazelayo | Isihlabathi esomile esihle |
| Vibration Molding | 3D Ukudlidliza | Ukudlidliza Okuqondile noma Okuvundlile |
| Ukuthela | Ukuthela Okubi | Ukuthela Okubi |
| Inqubo yesihlabathi | Khipha umfutho ongemuhle, vula ibhokisi ukuze uwise isihlabathi, bese isihlabathi sisetshenziswa kabusha | Yehlisa ingcindezi engalungile, bese isihlabathi esomile siwela esikrinini, bese isihlabathi sigaywa kabusha |
Yiziphi Izinzuzo Ze-Vacuum Casting?
1) Ivacuum castingsbabe nokunemba okuphezulu kobukhulu, uhlaka olucacile kanye nendawo ebushelelezi.
I-2) Azikho izibophezelo, amanzi kanye nezithasiselo esihlabathini sokubumba, okwenza ukucubungula kwesihlabathi kube lula.
3) Kulula ukuhlanza ama-vacuum castings. Amagesi ayingozi kancane akhiqizwa phakathi nenqubo yokuphonsa.
I-4) I-vacuum castings ingasetshenziswa ezinhlobonhlobo zezimboni. Ingasetshenziselwa ukukhiqizwa kweqoqo elincane lesiqephu esisodwa kanye nokukhiqizwa ngobuningi, ikakhulukazi ukulingisa okukhulu nosayizi omaphakathi kanye nokulingisa okunezindonga ezincanyana kulungele kakhulu ukusakazwa kwe-vacuum.
Yiziphi Izinsimbi nama-alloys Angaphonswa Ngokusakazwa Kwe-Vacuum?
• I-Grey Cast Iron, I-Ductile Cast Iron
• I-Carbon Steel: Ikhabhoni ephansi, ikhabhoni ephakathi nendawo nensimbi ye-carbon ephezulu
•I-Cast Steel Alloys: Insimbi ephansi ye-alloy, insimbi ephezulu ye-alloy, insimbi ekhethekile ye-alloy
• I-aluminium nama-alloys ayo
• Ithusi nethusi.
Insimbi eyinsimbi isho insimbi esetshenziselwa ukwakhiwa kwensimbi. Insimbi eyi-cast kufanele isetshenziswe lapho amandla okubunjwa aphezulu futhi ukusetshenziswa kwe-cast iron kungakwazi ukuhlangabezana nezidingo. Kodwa-ke, i-fluidity yensimbi encibilikisiwe yensimbi eyinsimbi ayilungile njengaleyo ye-cast iron, ngakho-ke ubukhulu besakhiwo sokuthulula akumele bube buncane kakhulu futhi ukuma akufanele kube nzima kakhulu. Uma okuqukethwe kwe-silicon kulawulwa emkhawulweni ongaphezulu, uketshezi lwensimbi encibilikisiwe lungathuthukiswa.Insimbi ye-Cast ingahlukaniswa ibe yinsimbi ye-cast alloy kanye nensimbi ye-carbon iron ngokusho kwamakhemikhali ayo, futhi ingahlukaniswa ngensimbi yensimbi, insimbi ekhethekile, ubunjiniyela kanye nokusakazwa kwesakhiwo kanye nensimbi ye-alloy cast ngokusho nezici zayo.
Insimbi ye-cast alloy ingahlukaniswa ibe yinsimbi ephansi ye-alloy (ingqikithi ye-alloy element ingaphansi noma ilingana no-5%), i-cast alloy steel (ingqikithi yezakhi ze-alloy ingu-5% kuya ku-10%) bese iphonsa insimbi ephezulu ye-alloy (ingqikithi ye-alloy). izakhi zinkulu noma zilingana no-10%).
