Cov pwm (mu ju) yog siv rau kev txhaj molding, tshuab moulding, extrusion, tuag casting los yog forging xovxwm molding, smelting, stamping thiab lwm txoj kev kom tau ntau yam pwm thiab cov cuab yeej yuav tsum tau siv cov khoom.Yog luv, lub pwm yog ib lub cuab tam kev ua molding cov khoom, uas yog ua los ntawm ntau qhov chaw, thiab ntau qhov chaw yog ua los ntawm ntau qhov sib txawv.Nws mas pom cov khoom ntawm cov khoom zoo los ntawm kev hloov lub cev lub cev ntawm cov ntaub ntawv molding.There yog lub npe "niam kev lag luam" .
Raws li sab nraud ua lub voj voog nrog ib hom khoom thiab me me.Nws yog dav siv hauv nias, forging, nias, hmoov hlau metallurgy, siab nrum, yas, roj hmab, ceramics, thiab lwm yam.Qhov pwm muaj ib qho kev contour lossis puab kab noj zoo, thiab cov duab ntawm cov hniav tuaj yeem sib cais raws li cov duab ntawm lub contour.Qhov zoo ntawm cov kab noj puab lub cev yuav siv tau los coj tus qauv sib thooj sib luag. Cov pwm feem ntau muaj ob feem: tsiv tuag thiab pwm (lossis punch thiab tuag), uas yuav muab faib ua ob qhov tib si.Txav rau daim thaum lawv sib cais, thiab ces tus paug yuav raug txhaj rau hauv cov pwm qhov kabmob.Hauv yog ib qho cuab yeej precision, txoj kev zoo, dais lub hwjchim loj ntawm cov billet, lub zog yam ntxwv , qhov nruj, qhov chaw tawv nqaij, qhov chaw roughness thiab machining cov neeg muaj kev thov dua, kev loj hlob qib ntawm puab pwm yog ib qho tseem ceeb ntawm cov theem ntawm cov khoom tsim.
