Iirimu zamavili e-alloy, ekwaziwa ngokuba ngamavili e-aluminiyam, ngamavili emoto enziwe ikakhulu kwi-alloy ye-aluminiyam (okanye ezinye izinto ezikhaphukhaphu ezifana ne-aluminiyam -ingxubevange ye-magnesium) ngeenkqubo eziquka ukunyibilikiswa, ukubunjwa kunye nokuphosa.
Xa kuthelekiswa nawo onke -amavili entsimbi, amavili e-alloy alula (anobunzima obuphakathi kwe-10–20% ngaphantsi), nto leyo enceda ukunciphisa ukusetyenziswa kwamafutha kunye nokuphucula ukuphatha kakuhle; zikwabonelela nge-thermal conductivity egqwesileyo, ukuxhathisa ukubola kunye nokuguquguquka kobuhle, okubenza ukuba bachithe ngokukhawuleza amaqondo obushushu aphezulu avelisiweyo ngexesha lokuqhobosha kwaye ngaloo ndlela banciphise umngcipheko wokonakala kwevili.
Uluhlu lweeMveliso
Ngokusekwe kwinkqubo yokwenziwa, amavili engxubevange ahlulahlulwe kakhulu abe ngamavili enziweyo (aphantsi kweendleko kwaye asetyenziswa kakhulu kwimveliso yobuninzi) kunye namavili abunjiweyo (anika amandla aphezulu kunye nobunzima obulula, kwaye aqhele ukusetyenziswa kwizithuthi ezisebenza{0}eziphezulu).
Amavili akhiweyo, ngokukodwa, aveliswa ngokufaka uxinzelelo lwamawaka okanye amashumi amawaka eetoni ukucinezela ngokuthe ngqo i-ingots ze-aluminiyam ezomeleleyo ukuze zimile, kufana nje 'nentsimbi yokubumba'. Zibonakaliswa ngamandla amakhulu, ubunzima obulula, ukuphucula ukusebenza kakuhle kwamafutha kunye nokuphathwa kakuhle. Amavili e-Cast, kwelinye icala, aveliswa ngokufudumeza i-aluminiyam ukuya kwimeko yolwelo, ukuyigalela kwi-mold kwaye ivumele ukuba iphole kwaye isete. Le nkqubo ilula, ixabisa{3}}iyasebenza kwaye ivumela ulwahlulo olubanzi loyilo. Ukwahlula phakathi kwezi zibini kulele ngokukodwa kwinkqubo yokuvelisa, okubangelwa ukungafani okuphawulekayo ekusebenzeni, ubunzima kunye nexabiso.
Uhlalutyo lokuthelekisa
| Igama lemveliso | Amavili enziweyo | Amavili e-Cast |
| Metal Ulwakhiwo | ubume bemolekyuli obuxinene ngokugqithisileyo, obungenabo porosity okanye ukukhululeka | inokuba nemingxuma emincinci, enesakhiwo esikhululekileyo |
| Amandla kunye Nokuqina | Amandla aphezulu kakhulu kunye nokumelana nempembelelo ebalaseleyo; nangona kunjalo, azinabulukhuni{0}}ngelixa kungalindelekanga ukuba ziqhekeke kwimpembelelo yobundlobongela, zinokuqhekeka kanye. | Amandla aphakathi kunye nokuqina okulungileyo; kungenzeka ukuba bagobe kwaye bagqwese kwimpembelelo yobundlobongela, ngaloo ndlela befunxa amandla empembelelo. |
| Ubunzima | ukukhanya; I-15–20% ikhaphukhaphu kunamavili atyhidiweyo anomlinganiselo ofanayo | ubunzima |
| Uyilo kunye neNkangeleko | Ngenxa yokuthintelwa kwenkqubo yokuvelisa, uyilo lwabo lulula, kodwa banikezela ngokuchaneka okuphezulu kakhulu komatshini. | Ziza kwiintlobo ngeentlobo zoyilo kwaye zinokuthatha uyilo oluntsonkothileyo noluntsonkothileyo. |
| Ixabiso | Phezulu; inkqubo yokuvelisa inzima, kwaye ixabiso liphindwe kaninzi kunelo lamavili, okanye nangaphezulu | Phantsi; ilungele imveliso yevolumu ephezulu-; ixabiso elihle kakhulu lemali |
Xa ukhetha amavili e-alloy, kuya kufuneka ulinganise iinketho zakho ngokusekwe kwiimfuno zakho zokwenyani. Ukusetyenziswa kosapho lwemihla ngemihla, khetha ukufa{1}amavili ecast, anika ixabiso elihle lemali, eze ngeendlela ezahlukeneyo, kwaye uqinisekise ukuhamba ngokukhuselekileyo. Ukuba ufuna amavili alula ukunyusa ukusebenza kokuphatha, okanye ukuba uneemfuno zohlengahlengiso, qwalasela amavili enziweyo, anika amandla amakhulu kodwa eze ngexabiso eliphezulu.
Ngaphaya koko, kufuneka ulumke ngakumbi xa uphucula ubungakanani bamavili. Musa ukulandela ngokumfameka ubungakanani obukhulu; kubalulekile ukuqinisekisa ukuhambelana okungqongqo kunye neeparamitha eziphambili zesithuthi, njengepateni yebholithi, i-offset (ixabiso le-ET) kunye ne-center bore. Ukungaphumeleli ukwenza oko kunokukhokelela kubunzima bofakelo, ukungcangcazela kwendlela okanye nakwiingozi zokhuseleko. Xa kuthengwa, kuyacetyiswa ukuba kubekwe phambili iimveliso eziphumelele isiqinisekiso somgangatho osemthethweni kunye nokuhlola ngononophelo umphezulu wevili kwiziphene ezifana ne-porosity, ii-cracks okanye i-burrs. Ziphephe iimveliso ezingafakwanga gama, nezingaqinisekiswanga 'ezintathu-ezingekho' naphi na apho kunokwenzeka ukuze uqinisekise ukhuseleko lokuqhuba.
