Cov Kev Pabcuam Casting Magnesium
Tsis yog magnesium tsuas yog lub teeb tshaj plaws ntawm txhua yam khoom siv uas muaj cov qauv xwb tab sis nws muaj qhov sib zog thiab lub zog-rau-qhov hnyav zoo heev. Tsis tas li ntawd, nws muaj cov khoom tiv thaiv EMI thiab RFI zoo heev, zoo meej rau cov khoom sib txuas thiab cov tsev hluav taws xob. Nws kuj tseem siv rau cov khoom siv kho mob thiab cov khoom siv hauv chaw kuaj mob. ISO 9001: 2015 thiab IATF 16949: 2016 tau ntawv pov thawj.
Magnesium Casting yog dab tsi?
Magnesium die casting yog ib txoj kev tsim khoom tshwj xeeb uas siv rau hauv kev tsim cov khoom siv hlau thiab cov khoom ua los ntawm magnesium alloy. Cov txheej txheem no, feem ntau hu ua magnesium alloy die casting, cuam tshuam nrog kev txhaj tshuaj magnesium molten rau hauv lub pwm lossis pwm qhov hauv qab siab. Cov khoom tshwm sim, tseem hu ua magnesium cast, yog ib daim duab lossis ib feem uas muaj cov yam ntxwv tshwj xeeb ntawm magnesium alloy.
Cov txheej txheem tsim cov magnesium pib nrog kev npaj cov magnesium alloy. Cov alloy raug yaj kom zoo hauv lub cub tawg thiab tom qab ntawd txhaj rau hauv lub pwm lossis qhov pwm. Feem ntau, cov pwm yog tsim los ntawm cov khoom siv ruaj khov xws li hlau thiab tau tsim kom zoo kom tsim tau cov duab kawg xav tau.
Thaum cov magnesium uas yaj lawm raug muab tso rau hauv qhov pwm, nws yuav txias sai thiab khov sai sai hauv qab kev siab siab. Txoj kev tsim khoom tshwj xeeb no tso cai rau kev tsim cov duab zoo nkauj thiab nyuaj uas yuav nyuaj rau ua tiav los ntawm lwm txoj hauv kev tsim khoom.
