Cov khoom muaj nyob rau hauv ntau yam specifications thiab hom, nrog sib txawv zoo thiab cov yam ntxwv. Lub raj mis xaiv tus number case yog ib qho yooj yim rau khaws thiab thauj, thiab tuaj yeem dipped sai sai thiab xim, ua rau nws tsim nyog rau kev xaiv tsa loj; lub dropper specification yog tsim los ua ib puag ncig tus phooj ywg thiab kev lag luam, thiab muaj peev xwm tswj tau tus nqi ntawm tus number case, uas tsis muaj khib nyiab los yog muaj peev xwm tswj tau tus nqi ntawm tus number case xaiv; cwj mem xaiv xaiv tus cwj mem yog lub teeb thiab nqa tau yooj yim, siv tau yooj yim, thiab yooj yim rau kev ceev cov npav ntawm qhov chaw xaiv tsa.

Kev tsim cov cwj mem xaiv xaiv suav nrog kev paub thiab thev naus laus zis hauv ntau qhov chaw xws li cov khoom siv tshiab, uas xav kom cov tuam txhab tsim khoom muaj qee qhov kev tsim khoom thiab kev tsim nyog. Cov neeg tsim khoom ua kom cov khoom lag luam zoo ntawm kev xaiv tus cwj mem los ntawm kev ua tib zoo sib xyaw cov ntaub ntawv raw, kho cov txheej txheem tseem ceeb, thiab tswj cov txheej txheem ntau lawm. Fujian Aobozi Tshiab Khoom Siv Technology Co., Ltd. yog tsim nyob rau hauv 2007. Nws tau qhia 6 lim kab tuaj ntawm lub teb chaws Yelemees thiab tau nruab nrog cov khoom siv tsis siv neeg puv puv puv. Nws muaj ntau lawm efficiency. Kev xaiv tus cwj mem nws tsim muaj kev ua tau zoo dua thiab ruaj khov zoo.
