Cov txheej txheem tseem ceeb ntawm kev nres ncoo yog kub nias moulding txoj kev, cov xovxwm kub yog muab faib ua ob pawg:Cov Txheej Txheem Ntau Lawm thiab Ntub Dej Ntau LawmCov. Feem ntau cov txheej txheem qhuav ntau lawm yog lub ntsiab, ntub cov txheej txheem ua haujlwm tsis yog tsuas yog ntau cov txheej txheem, ntev, kev lag luam hluav taws xob, thiab siv tau dav.
Cov txheej txheem ntau lawm yog nyob rau hauv kev sib txhuam phaj sib xyaw ua ke cov binder - cob lossis roj hmab los ntawm cov hmoov. Tus txheej txheem no muaj cov yam ntxwv hauv qab no:
1. Cov khoom sib tov ua ke yog cov hmoov puv hmoov sib xyaw.
2. Yooj yim pub rau cov txheej txheem ntawm kev nias, yooj yim rau kev faib covyees hauv cov embryo zoo, thiab tuaj yeem ua rau cov txheej txheem txias thiab tom qab no nias moulding.
3. Cov txheej txheem yooj yim, thiab cov khoom lag luam tuaj yeem hloov kho tau zoo.
4. Thaum lub sij hawm sib xyaw, cov fiber runing yog qhov zoo, thiab kev sib txhuam phaj lub zog yog siab.
5. Tus nqi ntawm kev sib txhuam phaj yog tsawg.
Vim tias cov kev zoo siab saum toj no, cov txheej txheem txheej txheem qhuav tuaj yeem ua tau raws li kev xav tau ntawm feem ntau cov kev sib txhuam cov tshuaj tam sim no.
