Kev faib pwm

Muab faib los ntawm cov qauv pwm, xws li cov txheej txheem pwm ib leeg, sib xyaw xuas nrig ntaus tuag, thiab lwm yam.;Muab faib los ntawm cov khoom siv, xws li tsheb npog qhov chaw, lub cev muaj zog pwm, thiab lwm yam .;Muab faib los ntawm cov khoom ua tiav, xws li pwm rau cov khoom siv hlau, pwm rau cov khoom tsis yog xim hlau, thiab lwm yam;Kev faib tawm ntawm cov khoom tsim pwm, xws licarbide pwm, lwm:

Kev faib tawm raws li cov txheej txheem, xws li kev sib sib zog nqus nqus, hmoov metallurgy, forging, thiab lwm yam. Qee qhov kev faib tawm no tsis tuaj yeem cuam tshuam tag nrho cov qauv thiab tsim cov txheej txheem ntawm ntau yam pwm, nrog rau lawv txoj haujlwm siv.Txog rau qhov kawg no, ib txoj kev qhia dav dav raws li qhov xwm txheejpwm tsimtxheej txheem thiab cov khoom siv tau txais yuav, thiab cov pwm tau muab faib ua: stamping pwm (punching tuag), yas molding pwm, tuag-casting pwm, forging pwm, hlau pwm rau casting, Muaj kaum pawg ntawmtungsten carbide hmoovmetallurgy pwm, iav khoom pwm, roj hmab moulding pwm, ceramic pwm, thiab pwm kev lag luam (pwm yooj yim).Txhua hom pwm loj tuaj yeem muab faib ua ntau pawg raws li cov qauv pwm, cov khoom siv, kev siv zog, thiab cov txheej txheem molding.Subclass los yog ntau yam
