Muaj 2 hom kev ua cov yas hwj, txheej txheem 1 kauj ruam lossis 2 kauj ruam.
Cov txheej txheem 1-kauj ruam, raws li lub tswv yim ntawm kev sib xyaw cov txheej txheem txhaj tshuaj tiv thaiv preform ncab-txheej txheem.PET fwj tau txais ncaj qha los ntawm cov yas PET cob rau hauv tib lub tshuab.
Cov txheej txheem 2-kauj ruam nthuav qhia kev tsim cov yas hwj hauv ob qhov sib cais: thawj cov qauv ua ntej yog txhaj tshuaj pwm ntawm lub tshuab txhaj tshuaj thiab tom qab ntawd rov kho dua thiab ncab-tshuab ntawm lub tshuab PET stretch tshuab. Ob lub tshuab (PET Blowing Machine thiab preform txhaj tshuab) yog qhov tsim nyog.
Eceng Machinery yog PET lub raj tshuab tshuab lub tshuab xa khoom ntawm 2-kauj ruam tus txheej txheem, los ntawm PET preform rau PET lub raj mis.
