I-China ye-OEM yesiko lokuphosa i-vacuum yokugalela iindawo ezisecaleni kwiimoto zikaloliwe ze-Cr-Mo zentsimbi exutywe nobushushu, unyango olungaphezulu kunyeCNC inkonzo yomatshini.
I-Vacuum Casting ikwabizwa ngokuba yi-Negative Pressure etywiniweyo, ukuNcitshiswa koxinzelelo okanyeV Inkqubo yokuSasa. Ukuphoswa koxinzelelo lwe-vacuum kufuna ukusetyenziswa kwezixhobo zokukhupha umoya ukukhupha umoya ngaphakathi kwendawo yokubumba, kwaye emva koko usebenzise umahluko woxinzelelo phakathi kwangaphakathi nangaphandle komngundo ukugubungela ifilimu eshushu yeplastiki kwipateni kunye netemplate. Ukubumba okutyhidiweyo kuya komelela ngokwaneleyo ukumelana nentsimbi etyhidiweyo ngexesha lokuphosa. Emva kokufumana i-vacuum mold, gcwalisa ibhokisi yesanti ngesanti eyomileyo ngaphandle kwe-binder, kwaye emva koko uvale umphezulu wesanti yokubumba ngefilimu yeplastiki, ulandelwe yivacuum ukwenza isanti iqine kwaye iqine. Emva koko, susa i-mold, ubeke iinqununu zesanti, uvale i-mold ukwenza yonke into ilungele ukugalelwa. Ekugqibeleni, ukuphosa kufunyenwe emva kokuba isinyithi esityhidiweyo sipholile kwaye siqiniswe.

Zeziphi izinto eziluncedo kwiVacuum Casting?
1) Iukuphoswa kwevacuumbabe nokuchaneka okuphezulu komgangatho, ulwandlalo olucacileyo kunye nomphezulu ogudileyo.
2) Akukho zibophelelo, amanzi kunye nezongezo kwintlabathi yokubumba, eyenza ukuqhutyelwa kwesanti kube lula.
3) Kulula ukucoca i-vacuum castings. Iigesi ezinobungozi ezincinci ziveliswa ngexesha lenkqubo yokuphosa.
I-4) I-vacuum castings ingasetyenziswa kuluhlu olubanzi lwamashishini. Ingasetyenziselwa imveliso yebhetshi encinci yesiqwenga esinye kunye nemveliso yobuninzi, ngakumbi iicastings ezinkulu neziphakathi kunye neentsimbi ezinodonga olucekethekileyo zifaneleke ngakumbi ukuphosa ivacuum.
Zeziphi iinyithi kunye ne-alloys ezinokuphoswa ngokusakazwa kweVacuum?
• I-ayini ye-Grey Cast, i-Ductile Cast iron
• Intsimbi yeCarbon: Ikhabhoni ephantsi, ikhabhoni ephakathi kunye nentsimbi yekhabhoni ephezulu
•Cast Steel Alloys: Intsimbi ephantsi ye-alloy, intsimbi ephezulu ye-alloy, intsimbi ekhethekileyo ye-alloy
• I-aluminiyam kunye neengxube zazo
• IBras & Copper.
Intsimbi yokuphosa ibhekisa kwintsimbi esetyenziselwa ukwenziwa kweentsimbi zentsimbi. Intsimbi yokuphosa kufuneka isetyenziswe xa amandla okuphosa aphakamileyo kwaye ukusetyenziswa kwentsimbi akukwazi ukuhlangabezana neemfuno. Nangona kunjalo, i-fluidity yensimbi etyhidiweyo yensimbi etyhidiweyo ayilungile njengentsimbi etyhidiweyo, ngoko ubukhulu besakhiwo sokugalela akufanele bube buncinci kwaye ubume akufanele bube nzima kakhulu. Xa umxholo we-silicon ulawulwa kumda ophezulu, i-fluidity yensimbi etyhidiweyo inokuphuculwa.Intsimbi yokuphosa inokohlulwa ibe yintsimbi yealloyi kwaye iphose intsimbi yekhabhoni ngokwemichiza yayo, kwaye inokwahlulwa ibe yintsimbi yesixhobo, intsimbi ekhethekileyo, ubunjineli kunye nolwakhiwo kunye nokuphosa intsimbi yentsimbi ngokweempawu zayo.
Intsimbi yengxubevange inokwahlulwa ibe yintsimbi ephantsi yealloyi (izinto ezipheleleyo zealloy zingaphantsi okanye zilingana ne-5%), intsimbi yealloy (izinto ezipheleleyo ze-alloy ziyi-5% ukuya kwi-10%) kunye nentsimbi ephezulu yealloy (i-alloy iyonke). izinto ezinkulu kuno okanye zilingana ne-10%).
