Ukuthetha ngezinto eziluncedo nezingeloncedoukuphosa ukufainkqubo:
inzuzo:
(1) Iindawo zetsimbi ezinemilo entsonkothileyo, inkcazo ecacileyo, iindonga ezibhityileyo kunye nemingxuma enzulu inokwenziwa.Ngenxa yokuba isinyithi esinyibilikisiweyo sigcina i-fluidity ephezulu phantsi koxinzelelo oluphezulu kunye nesantya esiphezulu, iindawo zetsimbi ekunzima ukuzisebenzisa ngezinye iinkqubo zinokufumaneka.
(2) Ukuchaneka komdaiicastings zokufaiphezulu, ukuya kwi-IT11-13 grade, ngamanye amaxesha ukuya kwi-IT9 grade, uburhabaxa bomphezulu bufikelela kwi-Ra0.8-3.2um, kwaye ukutshintshiselana kulungile.
(3) Izinga lokusetyenziswa kwezinto eziphathekayo liphezulu.Ngenxa yokuchaneka okuphezulu kwee-die castings, zinokudityaniswa kwaye zisetyenziswe kuphela emva komatshini omncinci, kwaye abanyeiicastings zokufainokuhlanganiswa kwaye isetyenziswe ngokuthe ngqo.Izinga layo lokusetyenziswa kwezinto eziphathekayo li malunga ne-60% -80%, kwaye izinga lokusetyenziswa elingenanto lifikelela kwi-90%.
(4) Ukusebenza okuphezulu kwemveliso.Ngenxa yokuzaliswa kwesantya esiphezulu, ixesha lokuzalisa lifutshane, imboni yensimbi iqinisa ngokukhawuleza, kwaye umjikelezo wokusebenza ngokufa ukhawuleza.Phakathi kweenkqubo ezahlukeneyo zokuphosa, indlela yokufa ineyona mveliso iphezulu kwaye ifanelekile kwimveliso yobuninzi.
(5) Ukusetyenziswa ngokulula kwezifakelo.Kulula ukuseta indlela yokubeka kwindawo yokubumba i-die-casting, elungele ukuphosa inlay kwaye ihlangabezana neemfuno zentsebenzo ezizodwa zendawoiindawo zokuphosa ukufa
ukusilela:
1. Ngenxa yokuzaliswa kwesantya esiphezulu kunye nokupholisa ngokukhawuleza, igesi kwi-cavity ishiywe kakhulu ukuba ikhutshwe, okubangelwa ubukho be-pores kunye ne-oxidized inclusions kwiindawo zokulahla i-die-casting, ngaloo ndlela ukunciphisa umgangatho weendawo zokufa. .Ngenxa yokwandiswa kwegesi kwi-pores kwiqondo lokushisa eliphezulu, umphezulu we-die-casting uya kubhobhoza.Ke ngoko, i-die-casting ene-pores ayinakunyangwa ngobushushu.
2. I-Die-castingoomatshini kunye ne-die-casting molds ziyabiza kwaye azifanelekanga kwimveliso encinci yebhetshi.
3. Ubungakanani be-die castings bukhawulelwe.Ngenxa yokunciphisa amandla okubamba umatshini wokufa kunye nobukhulu besikhunta, akunakwenzeka ukufa-ukuphosa iindawo ezinkulu zokufa.
4. Iindidi zee-alloys zokufa zilinganiselwe.Ngokubaukufa-kuphosaukungunda kuthintelwe ngubushushu bokusebenza, okwangoku zisetyenziselwa i-die-casting zinc alloys, i-aluminium alloys, i-magnesium alloys kunye nealloys zethusi.
