Kev nce qib ntawm cov khoom siv tsis siv neeg xws li kev pub noj tsis siv neeg, tshuab leveling thiab cov khoom khib nyiab rau punch yog qhov tseem ceeb heev. Nws muaj peev xwm daws tau cov teeb meem no thiab muaj plaub qhov zoo:
1. Kev ua haujlwm puv puv tsis siv neeg pub mis yog siv rau hauv kev tsim khoom ntawm kev tuag tas li ntawm cov punch xovxwm, uas yog tsim los tshem tawm qhov tshwm sim ntawm kev nyab xeeb: cov kab ntau lawm tsis siv neeg ntawm cov punch xovxwm siv cov ntaub ntawv coiled, uas tuaj yeem paub txog uncoiling, leveling thiab pub. Tsis tas yuav tsum muaj kev tuav haujlwm hauv kev nruam stamping, uas yog tsim los tshem tawm cov kev phom sij ntawm kev nyab xeeb.
2. Kev siv zog ua haujlwm tsawg thiab cov khoom tsim tau tsim muaj kev ywj pheej: ntxiv rau kev ua haujlwm thaum ntxov thiab kev sim khiav ntawm cov punch tsis siv neeg ntau lawm kab, tsis tas yuav tsum muaj kev tuav haujlwm hauv kev ua raws. Ib tus neeg teb xov tooj tuaj yeem ua haujlwm ntau cov kab ntau lawm, uas tsis yog tsuas yog txo cov kev siv zog, tab sis kuj tso tawm cov khoom tsim tau tiag tiag.
3. Kev ua haujlwm siab tas mus li thiab kev ua tau zoo ntawm cov khoom tiav: kev tsim cov khoom siv tsis siv neeg ntau lawm kab ntawm cov punch feem ntau ntau pua lub sij hawm ntawm phau ntawv stamping, thiab qhov yuam kev ntawm txhua kauj ruam yog tshem tawm los ntawm cov cuab yeej tshwj xeeb so kom ntseeg tau qhov zoo ib yam. ntawm cov khoom tiav.
