Hauv extrusion tshuab molding (EBM), yas yog melted thiab extruded rau hauv ib tug hollow raj (ib tug parison). Qhov no parison yog ces ntes los ntawm kaw nws mus rau hauv ib tug txias hlau pwm . Cua yog ces cua tshuab mus rau hauv lub parison, inflating nws mus rau hauv cov duab ntawm lub hollow lub raj mis, thawv, los yog ib feem.

Hauv qhov no, lub tshuab Moulding tshuab ua haujlwm li cas?

Tshuab molding yog cov txheej txheem ntawm kev tsim lub raj molten (hu ua parison lossis preform) ntawm cov khoom siv thermoplastic (polymer lossis resin) thiab muab cov parison lossis preform nyob rau hauv pwm kab noj hniav thiab inflating lub raj nrog compressed cua, coj cov duab ntawm kab noj hniav thiab txias ib feem ua ntej tshem tawm ntawm lub pwm.

Kuj Paub, dab tsi yog qhov txheej txheem txhaj tshuaj molding? Txhaj Tshuab Moulding . Tshuab molding yog txheej txheem ntawm inflating kub, hollow, thermoplastic preform los yog parison nyob rau hauv ib tug kaw pwm , yog li nws cov duab conforms rau ntawm cov pwm kab noj hniav. Muaj ntau yam tshuab molded hollow qhov chaw, nrog rau lub raj mis yas, tuaj yeem tsim los ntawm ntau yam yas siv qhov no txheej txheem.

Ntawm no, qhov txawv ntawm extrusion tshuab moulding thiab txhaj tshuaj molding yog dab tsi?

Cov Extrusion tshuab Moulding txheej txheem tsim ib tug ob-seem khoom whereas lub txhaj tshuaj molding txheej txheem tsim cov khoom peb-dimensional raws li qhov kawg tso zis. Qhov thib ob sib txawv lus dag hauv cuab yeej uas yog siv nyob rau hauv ob qho tib si txheej txheem.

Dab tsi yog cov theem ntawm tshuab Moulding?

Feem ntau, muaj peb yam tseem ceeb ntawm tshuab molding : extrusion tshuab molding , txhaj tshuaj tshuab molding , thiab txhaj tshuaj stretch tshuab molding . Cov tshuab molding txheej txheem pib nrog melting cia cov yas thiab tsim nws mus rau hauv ib tug parison los yog, nyob rau hauv cov ntaub ntawv ntawm kev txhaj tshuaj thiab txhaj stretch tshuab molding (ISB), preform.
