Boitšoaro bo Chesang ba Tlhakiso e Chesang ba Motsoako oa Die-Cast AZ91D Magnesium

Ka lebaka la thepa ea eona e ikhethang, kananelo ea lits'epe tse kopantsoeng ka magnesium indastering e ntse e eketseha, 'me pharalla ea kopo le eona ea hola. Hona joale, ka sehloohong eaba ba etsa tshebetso ya ho magnesium motsoako ke shoa-lahla. Ka tlhahiso ea 'nete, ka lebaka la litlhoko tsa maemo a ho sebetsa kapa lintlha tsa tšebetso, hangata hoa hlokahala ho etsa machining ea polasetiki e sa fellang kapa e akaretsang ea magnesium alloy die castings. Ka nako e ts'oanang, ts'ebetso ea polasetiki ea li-cast cast e ka felisa shrinkage le porosity e bakiloeng ke ts'ebetso ea ho lahla. , Ntlafatsa likarolo tse phethahetseng tsa mochini oa thepa. Leha ho le joalo, lits'epe tse kopantsoeng tsa magnesium li na le polasetiki e fokolang 'me ho thata ho li etsa ka polasetiki mochesong oa kamore; li-alloys tsa magnesium tsa die-cast li thata haholo ho etsa machining a polasetiki ka mocheso oa kamore ka lebaka la boteng ba likarolo tse haufi tsa marang-rang tse qhibilihisang moeling oa lijo-thollo, 'me ka kakaretso li hloka machining ea thermoplastic.
