Tshuab moulding yog ib txheej txheem zoo heev rau kev tsim khoom Hollow yas khoom. Nws cuam tshuam nrog tso rau ib tug parison alison rau hauv pwm thiab ntxiv nws siv cov cua compressed. Nws yog dav siv nyob rau hauv lub ntim, Automotive, kho mob, thiab cov kev lag luam. Nws cov ntsiab lus zoo nyob hauv nws lub peev xwm los tsim cov chaw nrog cov txheej txheem nyuaj, thiab lub teeb sib npaug ntawm cov nqi, thiab ntsuas hluav taws xob tsis zoo thiab thev taus.
Based on the technical principles, blow molding is divided into three categories: extrusion blow molding, injection blow molding, and stretch blow molding. Extrusion tshuab moulding yog qhov haum rau cov thawv loj thiab hollow tshuab moulding ntawm qhov xav tau siv nyob rau hauv cov ntawv thov, xws li tshuaj ntsuam, xws li cov tshuaj uas xav tau. Ncab tshuab moulding txhim kho khoom siv zog los ntawm kev ncab kev ncab, txuas ntxiv kho cov khoom siv tshuab ntawm cov khoom tiav. Qhov yooj yooj yim ntawm cov txheej txheem no ua rau cov khoom siv roj ntau, xws li cov khoom siv roj kev ua si, lossis cov kev xav tau ntawm cov khoom ntim ntim.
Kev xaiv cov khoom yog qhov tseem ceeb rau kev ua haujlwm ntawm tshuab pwm. Polyethylene (PE), polypropylene (PP), thiab polyethylene terephthalate, muaj cov ntaub ntawv tseem ceeb, thiab pob tshab ntim, feem. Nyob rau hauv xyoo tsis ntev los no, kev qhia ntawm enasticering plastics xws li polycarbonate (pc) tau nthuav dav qhov hauv siab {} {{4 4}}}} lub zog applications. Tsis tas li ntawd, los ntawm kev sib xyaw thiab kev hloov kho lossis ntxiv cov nplaim taws retardants, cov khoom siv tshwj xeeb muaj peev xwm ua tau tshwj xeeb ntxiv.
Tus nqi ntawm tshuab - moulded seem lus dag tsis tsuas yog nyob rau hauv kev tsim khoom ua haujlwm tab sis kuj nyob hauv lawv txoj kev txhawb nqa kom muaj kev txhim kho. Lub khaub ncaws hnav ncaj qha txo qis kev thauj hluav taws xob, thaum cov kev siv hluav taws xob thoob plaws los siv cov txheej txheem rau kev lag luam ncig. Nrog rau kev sib koom ua ke ntawm digital pwm tshuab thiab txawj ntse tswj cov tshuab, lub tshuab moulding muaj zog ntawm cov nqi siab dua thiab muaj txiaj ntsig zoo rau kev lag luam ntau rau ntau yam kev lag luam.
