1. Los Ntawm Txhais Tes. Tus neeg teb xov tooj tuav cov cutter thiab, raws sab ntug ntawm cov khoom, maj kho tus txeej. Qhov no yog qhov txheej txheem txheej thaum ub. Kev ua haujlwm tsis zoo, tsis muaj kev ruaj ntseg zoo, tshwj xeeb tshaj yog rau cov me me, kev siab tshaj ntawm O-ring yog qhov nyuaj ua kom tiav, netting, thiab yooj yim rau kev puas tsuaj rau lub cev khoom thiab phwj ntawm lub chaw txuas. Feem ntau tawm cov hniav cuav, khoob, kom khiav tawm cov roj, tov thiab lwm yam teebmeem ntawm kev sib tsoo ntawm qhov teeb meem tom qab. Lwm yam tshaj li qhov ntawd.
Kev vam khom rau ntawm kev siv phom rau kev ua haujlwm zoo kuj tseem ceeb.
2. Cov neeg kho tshuab. Yuav kom txhim kho tau qhov zoo thiab ua tau zoo dua, cov khoom siv hluav taws xob tau tshwm sim. Feem ntau yog siv lub tshuab fais fab tshwj xeeb nrog cov tshuab tig. Cov hniav siv rau kev sib raug zoo ntawm cov khoom muag. Yog tias muaj kev txeej ntawm sab hauv thiab sab npoo ntawm qhov khoom. Nws tuaj yeem tsim tau ua ob-edged, ntau ntug. Ua tiav ib qho tiav. Cov cuab yeej ua hauj lwm ntawm cov neeg ua hauj lwm trimming ntau dua li ntawm cov ntawv trimming, thiab qhov ua hauj lwm zoo tshaj yog ob npaug, tshwj xeeb tshaj yog rau ib hom hom kab noj hniav, uas tau tsim los kom phim cov cuab yeej raws li qhov kev npaj thiab kev faib khoom. Tom qab cov khoom no tawm ntawm pwm. Yuav yog tag nrho version ntawm lub tes tsho, ib zaug ua tiav qhov xuas nrig ntaus. Cov cua kub, muaj kaum ob zaug kho tau ib zaug.
Qhov tseem ceeb yog tias qhov xuas ntsuas kub yuav tsum yog tus tswj kom tiv thaiv kom tsis txhob ntev dhau.
3. Khov thiab kho qhov rooj. Cov khoom tiav nrog zoo vulcanization, ua ke nrog cov khib nyiab ntug, raug tshem tawm hauv cov dej khov nab. Kev siv technology yog tsim los ntawm Nyiv Showa carbonate thiab hauv Chao Precision co-invention, xyoo lawm, nrog xaiv cov khov nab kuab, hloov thiab txhim kho txhua yam kev ua haujlwm, khov kho trimming kuj tau ntsib ntau tiam neeg ntawm kev txhim kho, maturing thiab zoo, ua hauj lwm zoo thiab kev ua tau zoo tau zoo tuaj lawm.
