Moulding hauv kev tsim cov khoom yas Qhov txuas tseem ceeb hauv kev ua yas. Ntau hom yas (hmoov, pellets, kev daws teeb meem lossis kev faib tawm) tau tsim ua cov khoom lossis cov khoob ntawm qhov xav tau. Muaj ntau npaum li peb caug hom kev txhaj tshuaj molding. Nws qhov kev xaiv feem ntau yog txiav txim siab los ntawm hom yas (thermoplastic lossis thermosetting), thawj daim ntawv, thiab cov duab thiab qhov loj ntawm cov khoom. Feem ntau siv txoj hauv kev rau kev ua cov yas ntawm cov yas suav nrog extrusion, txhaj tshuaj molding, calendering, tshuab moulding thiab thermoforming. Kev ua yas yas ntawm cov thermoset yas feem ntau siv cov yas molding, hloov moulding, thiab txhaj tshuaj molding. Laminating, molding, thiab thermoforming tab tom tsim cov yas ntawm ib qho chaw tiaj. Cov txheej txheem txheej txheem yas saum toj no tuaj yeem siv rau kev ua cov roj hmab. Ib qho ntxiv, muaj cov castings siv cov kua monomers lossis polymers ua raw khoom. Ntawm cov txheej txheem no, kev siv extrusion thiab txhaj tshuaj molding feem ntau siv, thiab lawv kuj yog cov txheej txheem yooj yim tshaj plaws.
Cim npe nrov: cov yas muaj xim zoo nkauj thiab nylong gasket rau kev sib khi, Tuam Tshoj, cov chaw muag khoom, chaw tsim khoom, lub Hoobkas, ntau, pheej yig, tus nqi qis, hais lus
