Lub tshuab tshuab moulding yog ib yam khoom siv uas siv cov txheej txheem tshuab moulding los tsim cov thawv hollow los ntawm cov yas granules. Cov hom muaj xws li ib- kauj ruam tshuab moulding tshuab siv PP thiab PE, txhaj tshuaj stretch tshuab moulding tshuab siv PET, PC, los yog PP rau ob-kauj ruam molding, thiab tsim tshiab multi- txheej tshuab moulding thiab stretch tshuab moulding tshuab.
Feem ntau cov tshuab tshuab moulding tseem yog ob- cov tshuab kauj ruam, txhais tau tias cov khoom siv yas yuav tsum tau ua ntej ua ntej ua ntej tshuab. Tam sim no, PET, ib puag ncig tus phooj ywg yas, feem ntau siv. Lub tshuab tshuab moulding: Lub tshuab no txau cov kua yas thiab siv cov cua ntws los tshuab lub cev yas rau hauv pwm kab noj hniav ntawm ib qho tshwj xeeb los tsim cov khoom. Nws kuj yog ib hom tshuab moulding tshuab, uas yog lub tshuab hydraulic tshuab moulding.
Tubular yas preforms tau los ntawm extrusion los yog txhaj tshuaj molding ntawm thermoplastic resin yog muab tso rau hauv ib tug sib cais pwm thaum kub (los yog rhuab mus rau ib tug softened xeev). Tom qab cov pwm raug kaw, compressed cua yog tam sim ntawd nkag mus rau hauv lub preform kom inflate nws thiab ua kom nws nruj nreem rau lub puab phab ntsa ntawm cov pwm. Tom qab txias thiab demolding, ntau yam khoom hollow tau txais.
