Raws li txoj kev ua lub parison, tshuab moulding tau muab faib ua extrusion tshuab moulding thiab txhaj tshuaj molding.Cov tsim tshiab muaj xws li ntau txheej tshuab moulding thiab stretch tshuab moulding.Qhov txawv ntawm ob lub qauv yog dab tsi?
Extrusion, tseem hu ua extrusion tshuab moulding, yog ib txoj hauv kev siv lub tshuab extruder (extruder) kom ua tiav dhau cov khoom siv hluav taws xob los ntawm kev tuag rau extrude ib yam khoom ntawm qhov xav tau.Extrusion kuj qee zaum siv hauv molding ntawm thermosets thiab tuaj yeem siv rau hauv molding ntawm foamed plastics.
Qhov kom zoo dua ntawm extrusion tshuab moulding yog tias nws tuaj yeem extrude cov khoom ntawm ntau yam duab, nrog kev ua haujlwm siab, thiab tuaj yeem ua haujlwm thiab ua haujlwm tas mus li;Qhov tsis zoo yog tias cov thermosetting plastics feem ntau tsis tuaj yeem ua tiav los ntawm txoj kev no, thiab cov khoom lag luam loj tuaj yeem nyiam.
Kev txhaj tshuaj molding tseem hu ua txhaj tshuaj molding.Kev txhaj tshuaj molding yog ib txoj hauv kev siv lub tshuab txhaj tshuaj molding (los yog lub tshuab txhaj tshuaj) los txhaj cov thermoplastic yaj rau hauv pwm nyob rau hauv siab, thiab tom qab ntawd txias thiab khov kom tau cov khoom.Txhaj tshuaj molding kuj tseem siv tau rau molding ntawm thermosets thiab foams.
Qhov zoo ntawm kev txhaj tshuaj molding yog tias qhov ntau lawm ceev, qhov ua tau zoo yog siab, kev ua haujlwm tuaj yeem ua haujlwm, thiab nws tuaj yeem tsim qhov chaw nrog cov duab nyuaj, uas yog tshwj xeeb tshaj yog tsim rau ntau lawm.Qhov tsis zoo yog tias tus nqi ntawm cov khoom siv thiab cov pwm yog siab, thiab cov kua dej ntawm cov tshuab txhaj tshuaj molding yog qhov nyuaj.
Tshuab moulding tseem hu ua hollow tshuab moulding lossis hollow molding.Tshuab moulding yog ib txoj kev ntawm inflating ib tug kub resin parison kaw nyob rau hauv lub pwm rau hauv ib tug hollow khoom los ntawm txoj kev ntawm lub siab ntawm compressed cua.Tshuab moulding muaj xws li ob txoj kev tshuab tshuab thiab tshuab hollow khoom.Cov khoom ua yeeb yaj kiab, ntau lub raj mis, thoob, jugs thiab cov khoom ua si menyuam yaus tuaj yeem tsim los ntawm tshuab moulding.
Piv txwv li, vim li cas lub raj mis tsuas yog siv cov txheej txheem tshuab moulding, tab sis tuaj yeem siv kev txhaj tshuaj molding?Yog vim li cas yog qhov chaw sab hauv ntawm lub raj mis loj thiab lub qhov ncauj ntawm lub raj mis me me, yog li cov tub ntxhais txhaj tshuaj molding tsis tuaj yeem raug tshem tawm.Yog li ntawd, tshuab moulding manufacturers sandwich cov yas mos yaj nyob rau hauv nruab nrab ntawm cov pwm thiab tshuab nws kom nws lo rau lub puab phab ntsa ntawm pwm yam tsis siv ib tug core.
