Kev taw qhia txog txheej txheem
Extrusion tshuab moulding yog ib txoj hauv kev ua hollow thermoplastic qhov chaw. Cov khoom siv tshuab tshuab uas paub zoo muaj xws li lub raj mis, lub thoob, cov kaus poom, lub thawv, thiab tag nrho cov thawv ntim khoom noj, dej haus, tshuaj pleev ib ce, tshuaj, thiab khoom siv txhua hnub. Lub tshuab ntim loj molded feem ntau yog siv los ntim cov khoom siv tshuaj, cov roj nplua nyeem thiab cov khoom siv ntau.

Daim duab txheej txheem
Yas → plasticizing thiab melting → extrusion parison → inflation → khoom txias → demoulding → post-processing → khoom
cov kauj ruam ntxaws
duab
Kauj Ruam 1: Ncuav cov khoom polymer rau hauv cov pwm tawv, thiab tsim ib qho colloidal hollow columnar qauv los ntawm cua sov thiab mandrel nruam extrusion
duab
Kauj Ruam 2: Thaum lub hollow columnar qauv yog extruded rau ib qho ntev, cov pwm ntawm sab laug thiab sab xis pib kaw, thiab sab saum toj ntawm tus qauv yuav raug txiav los ntawm cov hniav kom haum rau ib qho ntev, thiab cua. yuav raug txhaj rau hauv tus qauv los ntawm tus pas nrig inflatable, kom tus qauv nyob ze rau ntawm phab ntsa sab hauv ntawm pwm kom txias thiab khov kho, tsim cov duab uas xav tau.
Kauj Ruam 3: Tom qab qhov txias dhau lawm, cov pwm ntawm sab laug thiab sab xis yog qhib thiab cov khoom raug demolded
duab
Kauj Ruam 4: Txiav ib feem nrog cov cuab yeej kho
