Muaj rau cov txheej txheem hlau, xws li casting, forging, stamping, machining, hmoov metallurgy thiab txhaj tshuaj molding. Casting: casting yog ib txoj kev ua kom yaj thiab nchuav hlau rau hauv pwm kab noj hniav sib haum rau cov duab thiab qhov loj ntawm cov khoom, thiab tos kom nws txias thiab khov, thiaj li tau txais cov khoom xav tau. Casting yog tsim nyog rau kev tsim ntawm qee qhov loj.
Forging, forging yog ib txoj kev ua haujlwm uas siv cov tshuab forging los ua kom lub zog ntawm cov khoom xyaw hlau los tsim cov yas deformation, thiaj li tau txais qee yam khoom siv, qee yam duab thiab ntau thiab tsawg. Forged yuam sij feem ntau xav tau machining los pab lawv ua tiav. Stamping yog ib txoj kev ua haujlwm uas siv lub zog sab nraud rau daim hlau, strips, cov kav dej thiab cov profiles los ntawm kev nias thiab tuag los tsim cov yas deformation lossis kev sib cais, thiaj li tau txais cov khoom tsim nyog.
Machining yog txheej txheem uas siv cov cuab yeej ncaj qha los txiav tawm ntau cov hlau ntawm qhov khoob hauv cov txheej txheem tsim khoom los ua kom nws ua tau raws li qhov yuav tsum tau ua ntawm daim duab. Qhov no yog qhov peb feem ntau hu ua tig, milling, npaj, sib tsoo, tso tawm thiab lwm yam kev siv thev naus laus zis. Tus neeg twg uas tau kawm nws paub tias machining yog tsim nyog rau kev ua ntawm ib feem. Hmoov metallurgy yog cov txheej txheem uas cov hmoov hlau thiab cov hmoov tsis yog hlau sib xyaw ua cov khoom siv raw, nias rau hauv cov duab, tom qab ntawd sau thiab compacted, thiab thaum kawg cov ntsiab lus hlau yuav tsum tau txais. Nws cov qauv yog qhov yooj yim thiab nws qhov ceev yog qhov siab.
Kev txhaj tshuaj molding yog sib tov cov hmoov hlau nrog cov nplaum yas, qhwv cov hmoov hlau los ntawm cov yas yaj, thiab tom qab ntawd txhaj cov khoom sib tov rau hauv pwm kab noj hniav los ntawm lub tshuab txhaj tshuaj. Thaum kawg, cov nplaum yas hauv cov nyiaj dawb huv cleaver raug tshem tawm los ntawm cov txheej txheem tshuaj lom neeg lossis thermal decomposition, thiab thaum kawg tau sau thiab densified kom tau txais cov hlau kawg, uas yog tsim nyog rau cov khoom loj ntawm cov khoom me me.
