Kune zvikamu zvealuminium, zvinogona kuumbwa kuburikidza nekukandira jecha, kukanda kwechigarire mold uye kufa kwekukanda maitiro.

Die casting inzira yekugadzira yekugadzira yakanyatso mativi, yakatsanangurwa zvakanyanya, yakatsetseka kana yakashongedzwa-pamusoro pesimbi zvikamu.Inoitwa nekumanikidza simbi yakanyungudutswa pasi pekumanikidzwa kwepamusoro kuita simbi inoshandiswa zvakare inofa.Maitiro acho anowanzo kutsanangurwa sechinhambwe chipfupi pakati pezvakagadzirwa uye chigadzirwa chapera.Izwi rekuti "die casting" rinoshandiswawo kutsanangura chikamu chakapedzwa.

Izwi rekuti "permanent mold casting" rinodaidzwawo kuti "gravity die casting" Rinoreva zviumbwa zvakagadzirwa nesimbi pasi pemusoro wegiravhiti.

Permanent mold casting inoshandisa simbi kana imwe simbi molds uye cores.Kukanda kwakasimba kunoumbwa nekudururira aluminium muforoma.Zvisingaperi molds anoshandiswa kugadzira zvakanyanya kudzokorora zvikamu nekuenderana.Mareti avo ekukurumidza ekutonhodza anoburitsa yakawedzera kuenderana microstructure, iyo inogona kuvandudza ma mechanic properties zvakanyanya.

Permanent mold casting inoshandiswa kugadzira mavhiri alloy.Mavhiri eAluminium zvakare akareruka kupfuura mavhiri esimbi, anoda simba shoma kuti atenderere.Ivo vanopa hukuru hwemafuta kunyatsoshanda, pamwe nekubata zvirinani, kukurumidza, uye braking.Nekudaro, kune inorema-basa maindasitiri track application, mavhiri esimbi anonyanya kushandiswa.Kugara kwadzo kunoita kuti zvisave nyore kukotama kana kutsemuka.Kana yakashandiswa panjanji, mavhiri esimbi anowedzera kukanganwira kukanganisa kwenzira, kuwedzera kuchengetedzeka.

Kukandwa kwejecha kunogadzirwa nekurongedza musanganiswa wejecha wakanaka wakatenderedza patani yechigadzirwa chaunoda.Iyo pateni yakati kurei pane yekupedzisira chigadzirwa kubvumira shrinkage yealuminium paunenge uchitonhora.Kukandira jecha kune mari nekuti jecha rinogona kushandiswazve kakawanda.Izvo zvinoshandawo pakugadzira mahombe moldings kana ayo ane akadzama magadzirirwo.Mari yekumberi yemidziyo yakadzikira, asi pachikamu-chete mitengo yakakwira, zvichiita kuti jecha rive rakakodzerwa nehunyanzvi hwekukandira pamusoro pekugadzirwa kwakawanda.

Aluminium inokandira nehudiki hwayo, kuramba kwecorrosion uye akati wandei emhando yepamusoro, anoshandiswa zvakanyanya mumhepo, mota, michina uye mamwe maindasitiri.Kunyanya muindasitiri yemotokari, kuitira kuderedza kushandiswa kwemafuta kuvandudza mashandisirwo emagetsi, zvikamu zvakawanda zvemotokari zviri kuchinjirwa kuita aluminium zvinhu.
