Ua ntej, paub qhov txawv ntawm cov ntaub ntawv thiab tsim:
Qhov tseem ceeb tshaj plaws ntawm kev txhaj tshuaj molding pwm yog cov khoom, ces dab tsi zoo ntawm cov ntaub ntawv uas zoo? Ntawm chav kawm, qhov hard disk siab, qhov corrosion kuj muaj zog, thiab qhov kev ua haujlwm polishing zoo, thiab cov pwm siv tau ntev. Tag nrho cov qauv ntawm cov pwm, xws li thimble thiab core; qhov rooj tsim, ntu qhov chaw, qhov chaw nres tsheb, lub qhov rooj loj thiab qhov chaw tsim nyog, tom qab ntawd yog pom tias pwm txhaj qhib thiab kaw, cov khoom loj tsim nyog.
Tom qab ntawd koj tuaj yeem saib cov txheej txheem pwm:
Yuav kom paub qhov txawv ntawm kev siv cov pwm yas pwm, peb yuav tsum xub xyuas seb qhov kev txhaj tshuaj pwm puas yog tsim nyog. Qhov thib ob, qhov tsos ntawm qhov txhaj tshuaj molded yuav tsum huv, thiab qhov sib txuam nto, slider thiab cov tub ntxhais yuav tsum tsis muaj burrs. Yog tias tag nrho cov saum toj no tuaj yeem ua tiav, ces txheej ntawm cov pwm no yog tsim muaj pwm.
Thaum kawg, qhov txawv ntawm qhov zoo ntawm cov khoom pwm:
1. Stability and consistency ntawm cov khoom loj, qhov chaw tiav thiab cov khoom siv.
2. Kev pab cuam lub neej: Tus naj npawb ntawm kev ua hauj lwm ib qho pwm tuaj yeem ua tiav lossis ntau qhov khoom tsim tawm, thaum tswj qhov khoom zoo.
3. Kev siv thiab kev kho ntawm pwm yog qhov yooj yim tshaj plaws, txawm tias nws yog qhov yooj yim rau demould, txawm tias lub sij hawm ntu khoom tsim tawm yog luv li sai tau; kev them nqi kho dua, kev hloov txij nkawm, thiab lwm yam.
Paub txog cov nram qab no, peb tuaj yeem nrhiav kev los txhim kho qhov pwm zoo. Txoj kev tsim cov qauv pwm yooj yim yog cov kauj ruam tseem ceeb tshaj plaws los txhim kho qhov pwm. Ntau yam yuav tsum tau muab xam, xam cov kev xaiv cov khoom pwm, kev siv tau thiab kev ruaj ntseg ntawm cov qauv puab. Lub puab moom tuaj yeem ua tiav thiab pwm txoj haujlwm yog yooj yim, thiab tus qauv tsim yuav tsum ua tib zoo xav.
