Ilori eLahlekileyo ye-Foam yokuphosa i-Gearbox Cover ye-Grey Iron

China OEM isiko ezilahlekileyo iimveliso zokuphosa amagwebu yeintsimbi engwevungokwemizobo yakho kunye neemfuno (ukwakheka kweekhemikhali zemathiriyeli, iipropati ezifunekayo zoomatshini, ukunyamezela, unyango lobushushu kunye nonyango lomphezulu), esetyenziselwa umsebenzi onzima webhokisi yegiya yelori.

Ukuphosa igwebu elilahlekileyo, elikwabizwa ngokuba yi-Lost Foam Casting (LFC) okanye i-Full Mold Casting, luhlobo lwe-Evaporative Pattern Casting (EPC) enenkqubo yokuphosa isanti eyomileyo. I-EPC ngamanye amaxesha inokuba mfutshane kwi-Expendable Pattern Casting kuba iipateni zogwebu ezilahlekileyo zingasetyenziswa kube kanye kuphela. Emva kokuba iipateni zamagwebu zigqitywe ngoomatshini abakhethekileyo, emva koko iipateni zeplastiki ezinogwebu zigqunywe nge-refractory coating ukuze zenze iqokobhe elomeleleyo lokumelana nentsimbi etyhidiweyo. Iipateni ze-foam ezinamaqokobhe zifakwa kwibhokisi yesanti, kwaye uyigcwalise ngesanti eyomileyo ejikelezileyo. Ngexesha lokuthululwa, isinyithi esinyibilikisiweyo esiphezulu sobushushu senza i-foam iphethini i-pyrolyzed kwaye "inyamalale" kwaye ibambe i-cavity yokuphuma yeepateni, kwaye ekugqibeleni i-castings efunwayo egqityiweyo ifunyenwe.

Intsimbi yokuphosa yintsimbi ye-iron-carbon cast alloy kunye nezinye izinto ezenziwe ngokunyibilikisa i-iron yehagu, i-scrap, kunye nezinye izongezo. Ukwahlula kwintsimbi kunye nentsimbi, isinyithi esityhidiweyo sichazwa njenge-alloy cast kunye nomxholo wekhabhoni (min 2.03%) oqinisekisa ukuqina kwesigaba sokugqibela kunye nokuguqulwa kwe-eutectic. Ngokuxhomekeke kwiinkcukacha zeekhemikhali, ii-ayini ezityhidiweyo zinokungafakwa okanye zifakwe alloyed. Uluhlu lweentsimbi ezidibeneyo lubanzi kakhulu, kwaye luqulethe ixabiso eliphezulu lamacandelo aqhelekileyo, njenge-silicon kunye ne-manganese, okanye izongezo ezikhethekileyo, njenge-nickel, i-chromium, i-aluminium, i-molybdenum, i-tungsten, ubhedu, i-vana-dium, i-titanium, kunye abanye. Ngokuqhelekileyo, intsimbi etyhidiweyo inokohlulwa ibe yintsimbi engwevu, intsimbi ye-ducitle (intsimbi ye-nodular), intsimbi emhlophe, intsimbi edityanisiweyo yegraphite kunye nentsimbi egayiweyo.

Amanyathelo okuphosa amagwebu alahlekileyo:
I-1- Sebenzisa i-foam molds ukuvelisa iipateni ze-foam kunye ne-gating systems
I-2- Bond iipateni kunye neembaleki ukwenza imodyuli ye-mold bundle
3- Dipha ipeyinti kwimodyuli
4- Yomisa ipeyinti
5- Beka imodyuli kwibhokisi yesanti kwaye uyigcwalise ngesanti eyomileyo
6- ngcangcazelisa ukubumba ukuze ugcwalise umngxuma ngesanti eyomileyo uze udibanise isanti ebumbayo
7- Ukugalela isinyithi esinyibilikisiweyo ukwenza umphunga we-foam kwaye wenze izinto ezifunwayo
8- Emva kokuba i-castings ipholile, coca ii-castings. Isanti eyomileyo inokuphinda isetyenziswe

Izinto eziluncedo zokuphosa ugwebu olulahlekileyo:
✔ Inkululeko enkulu yoyilo yolwakhiwo oluntsonkothileyo
✔ Akukho engile yokuyila efunekayo ukonga iindleko ezininzi.
✔ Iipateni ezidityanisiweyo zogwebu zinokudityaniswa kuthotho lweepateni zamagwebu.
✔ Ukusaswa kogwebu olulahlekileyo yinkqubo ekufutshane nenetha
✔ Ukuba bhetyebhetye okuphezulu ngamaxesha amafutshane okuseta
✔ Ubomi benkonzo yokubumba ye-EPS ende, kungoko kuthotywa iindleko zesixhobo
✔ Iindleko zeNdibano kunye nonyango ziyancitshiswa ngokushiywa kwenkqubo yonyango, iinxalenye zokufakela, ukudibanisa i-screw, njl.
✔ Ukwandiswa kobubanzi bezicelo

Iinyithi kunye ne-alloys zinokuphoswaInkqubo yokuphosa igwebu elilahlekileyo:
• I-ayini ye-Grey Cast, i-Ductile Cast iron
• Intsimbi yeCarbon: Ikhabhoni ephantsi, ikhabhoni ephakathi kunye nentsimbi yekhabhoni ephezulu
• I-Cast Steel Alloys: Insimbi ye-alloy ephantsi, intsimbi ephezulu ye-alloy, intsimbi ekhethekileyo ye-alloy
• I-aluminiyam kunye neengxube zazo
• IBras & Copper.

Imizi-mveliso ye-Foam elahlekileyo esetyenziselwe:
Njengoko kukhankanyiwe ngasentla, ukuphosa amagwebu elahlekileyo kulungele ngokukodwa ukuvelisa udonga olukhulu kunye nolungqingqwa. Bakhonza ubukhulu becalaiilori, oololiwe bakaloliwe, oomatshini bokwakha kunye nabanye oomatshini abanzima abaneemfuno zesakhiwo esintsonkothileyo sezinto ezifunwayo.

Unyamezelo lokuphosa olufikelelwe yiNkqubo yokuphosa ugwebu olulahlekileyo:
Ngokuqhelekileyo, ukunyamezela ukuphosa kwe-foam castings elahlekileyo kungcono kunoukugalela isanti, kodwa kubi ngakumbi kunokusalwa ngundo lweqokobhe kunye neenkqubo zokuphosa ezingabhaki. Kwisiseko sethu, sinokufikelela kula mabakala alandelayo. Kodwa singathanda ukuthetha nawe ngeecastings ezithile kwaye emva koko sithathe isigqibo sokuba ngawaphi amanani esinokukubonelela ngawo.
