Castings yog qhov tsim los ntawm immersing molten hlau los yog alloy nyob rau hauv lub pwm, tso cai rau nws mus rau tag nrho ntub cov pwm nto, tuav rau ib tug tej lub sij hawm, thiab ces txias thiab solidify, ua rau ib feem ntawm ib tug tshwj xeeb cov duab thiab loj. Casting yog ib qho txheej txheem tsim khoom hauv kev tsim khoom.
Castings tau dav siv hauv kev lag luam xws li aerospace, machinery, automotive, thiab metallurgy, thiab yog ib feem tseem ceeb ntawm kev tsim khoom. Cov cuab yeej siv tshuab loj, xws li cov nkoj thiab cov dav hlau, xav tau ntau cov castings los txhawb lawv cov qauv.
