1. Kev xaiv cov khoom siv: Xaiv cov ntaub ntawv xws li hnav-tiv taus, kub-resistant, thiab corrosion-resistant engineering plastics lossis alloy steel.
2. Kev ua haujlwm raug: xyuas kom muaj qhov tseeb ntawm cov pwm los txhim kho qhov zoo thiab kev pabcuam lub neej ntawm lub thawv noj su.
3. Kev tsim qauv: Cov qauv tsim ntawm cov pwm yuav tsum tsim nyog los txhim kho kev tsim khoom, txo cov nqi tsim khoom, thiab yooj yim los tswj thiab hloov cov khoom.
4. Tsis txhob deformation: Vim yog cov phab ntsa nyias nyias ntawm cov phab ntsa nyias nyias, nws yog ib qho tsim nyog yuav tsum xaiv cov khoom siv steel hardness siab thiab siv kev ntsuas los tiv thaiv pwm deformation nyob rau hauv lub sij hawm ntev ntawm kev kub ceev thiab kev kub siab.
5. Kev ua kom zoo rau lub tshuab ua kom txias: txhawm rau tiv thaiv cov khoom deformation, nws yog ib qho tsim nyog yuav tsum ua kom zoo dua qhov txias txias ntawm pwm, kom cov khoom tuaj yeem txias sai sai hauv lub sijhawm luv luv.
6. Tsis txhob muaj teeb meem jamming: Thaum tsim pwm, nws yog ib qho tseem ceeb uas yuav tsum xav txog kom tsis txhob muaj teeb meem jamming kom txo tau qhov zaus ntawm kev tu thiab hloov cov khoom.
7. Kev kho deg: Qhov saum npoo ntawm cov pwm yuav tsum tau polished los txhim kho qhov zoo ntawm cov khoom.
8. Cov teeb meem kev nyab xeeb: Thaum ua thiab kho cov pwm, nws yuav tsum tau ua tib zoo saib xyuas cov teeb meem kev nyab xeeb kom tsis txhob raug mob.
9. Cov teeb meem ib puag ncig: yuav tsum tau them nyiaj rau kev tiv thaiv ib puag ncig thaum lub sijhawm tsim khoom kom tsis txhob muaj kuab paug rau ib puag ncig.
