Forging: Cov txheej txheem ntawm shaping hlau los ntawm hammering thiab compression, ua nyob rau hauv ob qho tib si txias - ua hauj lwm los yog siab - kub; nws yog ib qho ntawm cov hlau uas yooj yim tshaj plaws thiab qub tshaj plaws - txheej txheem tsim.
Rolling: Ib txheej txheem uas rhuab hlau billets dhau los ntawm cov cylindrical rollers; cov chais no compress cov hlau mus rau hauv ib tug tuag kom ua tau ib tug predetermined zoo.
Hlau Drawing: Ib txheej txheem siv los hloov cov hlau rods rau hauv cov xov hlau zoo los ntawm rub lawv los ntawm kev tuag nrog cov kab me me.
Extrusion: Tus nqi- siv tau zoo, cov txheej txheem tsim khoom txuas ntxiv siv los tsim cov khoom zoo lossis hollow hlau nrog cov ntoo khaub lig sib xws- ntu; nws tuaj yeem ua tau nyob rau hauv ob qho tib si siab - kub thiab txias - ua haujlwm.
Impact Extrusion: Ib txheej txheem siv los tsim cov khoom me me mus rau nruab nrab- qhov loj me uas tsis tas yuav tsum muaj cov kab xev. Nws muaj kev tsim khoom sai, haum rau qhov sib txawv ntawm phab ntsa thicknesses, thiab suav nrog cov nqi tsim khoom tsawg.
Hmoov Metallurgy: Cov txheej txheem tsim khoom siv tau rau ob qho tib si ferrous thiab non{0}}ferrous hlau Cheebtsam. Nws suav nrog ob theem tseem ceeb: sib tov cov hmoov hlau alloy thiab compacting qhov sib tov rau hauv pwm.
Cov khoom hlau yog tom qab sintered (bonded) rau hauv ib daim ntawv los ntawm siab - kub cua sov. Cov txheej txheem no tshem tawm qhov xav tau ntawm machining, ua tiav cov khoom siv raw khoom siv txog li 97%, thiab tso cai rau kev siv cov hmoov hlau sib txawv los sau cov ntu tshwj xeeb ntawm cov pwm.
