Hmoov zoo, kev nkag siab tob txog cov khoom siv uas xav tau thiab daim ntawv thov npaj yuav pab nqaim cov npe ntawm cov kev xaiv uas muaj peev xwm ua tau zoo dua. Thaum xav txog daim ntawv thov, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov cov lus nug hauv qab no:
Qhov twg yuav siv tau?
Nws lub neej ua haujlwm ntev npaum li cas?
Cov kev ntxhov siab twg koom nrog hauv daim ntawv thov?
Puas yog kev zoo nkauj ua lub luag haujlwm, lossis yog qhov ua tau zoo ntawm qhov tseem ceeb?
Dab tsi yog cov kev txwv nyiaj txiag ntawm daim ntawv thov?
Ib yam li ntawd, cov lus nug hauv qab no muaj txiaj ntsig zoo thaum txiav txim siab cov khoom xav tau:
Dab tsi yog cov yam ntxwv ntawm kev siv tshuab thiab tshuaj lom neeg xav tau los ntawm cov yas?
Cov yas coj li cas thaum cua sov thiab cua txias (piv txwv li, thermal expansion thiab shrinkage, melting kub ntau, degradation kub)?
Cov yas muaj kev cuam tshuam dab tsi nrog huab cua, lwm yam yas, tshuaj, thiab lwm yam?
Xws li hauv qab no yog ib lub rooj ntawm kev txhaj tshuaj molding yas, txhua tus nrog nws tus kheej txheej ntawm qhov zoo thiab kev siv kev lag luam dav dav:

Thermoplastics yog qhov kev xaiv zoo tshaj plaws rau kev txhaj tshuaj molding. Rau ntau yam xws li recyclability thiab yooj yim ntawm kev ua. Yog li qhov twg cov khoom tuaj yeem tau txhaj tshuaj molded siv cov thermoplastic, mus rau qhov ntawd. Cov khoom lag luam siab hloov tau ntev tau xav tau qhov xav tau ntawm cov thermoset elastomers. Niaj hnub no koj muaj kev xaiv ntawm thermoplastic elastomers. Yog li ntawd koj qhov yuav tsum tau hloov tau yooj yim tsis tshem tawm cov kev xaiv ntawm kev siv cov thermoplastics. Kuj tseem muaj cov qib sib txawv ntawm TPEs los ntawm qib zaub mov mus rau TPEs ua haujlwm siab.
Cov khoom siv yas tau siv rau hauv cov khoom siv niaj hnub. Piv txwv yog polystyrene kas fes khob, polypropylene takeaway tais, thiab high-density polyethylene lub raj mis caps. Lawv pheej yig dua thiab muaj ntau dua. Engineering plastics tau siv nyob rau hauv, raws li lub npe implies, engineering applications. Koj yuav pom lawv hauv tsev cog khoom, cov ntawv vov tsev, thiab cov khoom siv. Piv txwv yog polyamides (Nylon), polycarbonate (PC), thiab acrylonitrile butadiene styrene (ABS). Lawv tuaj yeem tiv taus ib puag ncig hnyav dua. Lawv yuav tiv taus load thiab kub zoo tshaj chav tsev kub. Cov yas ua haujlwm siab ua tau zoo nyob rau hauv cov xwm txheej uas cov khoom lag luam thiab cov khoom siv hluav taws xob tsis zoo. Piv txwv ntawm cov yas ua tau zoo yog polyethylene ether ketone, polytetrafluoroethylene, thiab polyphenylene sulfide. Kuj tseem hu ua PEEK, PTFE, thiab PPS. Lawv pom kev siv hauv cov ntawv siv high-end xws li aerospace, cov cuab yeej kho mob, thiab lub zog. Kev ua haujlwm siab yog kim dua li cov khoom lag luam lossis cov yas engineering. Cov khoom ntawm cov yas pab koj txiav txim siab uas haum rau ib qho kev thov tshwj xeeb. Piv txwv li, qee daim ntawv thov xav tau cov khoom siv muaj zog tab sis hnyav. Rau qhov no, koj piv lawv qhov ceev thiab tensile lub zog.
