Muaj ntau hom pwm, uas tuaj yeem faib ua:
(1) hlau ua moulds raws li cov khoom ua thiab kev siv technology.
(2) ua cov xim hlau tsis sib xyaw thiab hmoov hlau metallurgy tuaj pwm. Xws li cov pwm yas (xws li ob hom xim pwm, compression pwm thiab extrusion pwm, thiab lwm yam.), Rubber pwm thiab hmoov hlau metallurgy tuaj pwm. Raws li cov yam ntxwv ntawm cov yam ntxwv, lub pwm tuaj yeem raug faib ua ib qho qauv pwm thiab muaj kab noj hniav nrog qhov chaw. Cov pwm no feem ntau yog ib qho khoom me me, cov khoom me me me me.
Kev Txheeb Xyuas Ntau Lawm
Cov pwm yog ib tus qauv, raws li qhov qauv no los ua cov khoom, tab sis cov pwm yog yuav ua li cas tsim nws, tej zaum yuav tsis teb feem ntau ntawm cov kws kho mob. Pwm tau ua lub luag haujlwm hauv peb lub neej, peb txhua hnub yuav tsum tau sib cais Feem coob tsis tuaj yeem raug cais tawm ntawm lub pwm, xws li cov computers, xov tooj, fax machine, keyboards, khob, etc. Cov khoom siv yas no tsis tas yuav hais, lwm lub tsheb thiab lub cev maus taus ntawm lub cav tseem muaj nrog pwm, lub teeb rau txhua lub tsheb Txhua hom pwm yuav siv ntau tshaj 20,000. Yog li ntawd, lub luag haujlwm ntawm lub neej niaj hnub tuaj yeem hloov tsis tau. Ntev npaum li cov khoom loj tuaj tsis tau muab cais tawm ntawm pwm.
