Cov txheej txheem ntim khoom yas molding hauv kev lag luam tshuaj pleev ib ce yog muab faib ua ob pawg: txhaj tshuaj molding thiab tshuab moulding.

Txhaj Molding

Txoj kev txhaj tshuaj molding yog dab tsi?

Kev txhaj tshuaj molding yog txheej txheem cua sov thiab ua kom cov yas (cua sov thiab yaj mus rau hauv cov kua dej, plasticity), thiab tom qab ntawd siv lub zog los txhaj rau hauv qhov chaw kaw pwm, cia nws txias thiab khov rau hauv pwm, tsim cov khoom nrog tib yam li cov pwm.Nws yog tsim rau huab hwm coj ntau lawm ntawm qhov chaw nrog complex duab.

Cov yam ntxwv ntawm kev txhaj tshuaj molding txheej txheem:

1. Ceev ceev ntau lawm, kev ua haujlwm siab, siab ua haujlwm automation

2. Cov khoom lag luam muaj qhov ua tau zoo, thiab qhov tshwm sim yuam kev me me heev

3. Muaj peev xwm tsim cov khoom nrog cov duab nyuaj

4. Tus nqi pwm siab

Feem ntau pebairless lub raj mis, ob-phab ntsa tshuaj pleev lub raj misyog tsim los ntawm kev txhaj tshuaj.

Tshuab molding

Cov yam ntxwv ntawm tshuab moulding txheej txheem:

Kev kos duab los ntawm cov txheej txheem iav tshuab tshuab ib txwm siv, tshuab moulding siv cov cua compressed nrog ib lub siab kom inflate thiab txias lub preform (semi-tiav tubular yas lub cev) hauv pwm rau hauv cov txheej txheem molding rau cov khoom hollow.Nws yog tsim rau loj zus tau tej cov hollow yas ntim.

Dab tsi yog cov yam ntxwv ntawm lub tshuab molding txheej txheem?

1. Txoj kev tsim khoom yooj yim, kev ua haujlwm siab ntau lawm thiab automation

2. Tsawg qhov tseeb qhov tseeb

3. Muaj qee yam kev txwv ntawm cov khoom zoo

4. Tsawg pwm tus nqi

Raws li cov txheej txheem ntau lawm thiab cov txheej txheem, tshuab molding tuaj yeem muab faib ua peb hom: extrusion tshuab, txhaj tshuab, thiab txhaj tshuaj stretch tshuab.

Thawj yog nyem thiab tshuab.Raws li lub npe qhia, extrusion tshuab muaj ob theem loj: extrusion thiab tshuab molding.

Thawj kauj ruam yog extrude lub parison-pwm kaw.Cov cuab yeej extrusion txuas ntxiv nyem los tsim lub hollow tubular parison.Thaum lub parison yog extruded mus rau ib tug predetermined ntev, sab saum toj ntawm lub parison yog txiav mus rau ib tug ntev haum rau ib daim, thiab cov pwm ntawm sab laug thiab sab xis yog kaw.

Qhov thib ob kauj ruam, huab cua qhia-trimming.Compressed cua yog txhaj rau hauv lub preform los ntawm mandrel kom inflate.Lub parison zoo adheres rau lub puab phab ntsa ntawm pwm kom txias thiab zoo, thiab cov khoom raug tshem tawm ntawm pwm, thiab lub thib ob trimming yog ua.Tus nqi ntawm extrusion thiab tshuab tshuab thiab pwm yog tus nqi qis, thiab cov nqi tsim khoom kuj tseem tsawg.

Txawm li cas los xij, flashing tshwm sim thaum lub sij hawm tsim khoom, thiab lub qhov ncauj thiab hauv qab ntawm lub raj mis yuav tsum tau muab txiav los ntawm mechanically lossis manually, thiab qee zaum lub qhov ncauj ntawm lub raj mis yuav tsum tau polished thiab trimmed.

Extrusion-blow molded yas fwj muaj ib txoj kab sib cais (ib txoj kab ncaj nraim) nyob rau hauv qab, thiab lub qhov ncauj ntawm lub raj mis yog ntxhib thiab tsis du, yog li qee qhov muaj kev pheej hmoo ntawm cov kua xau.Cov fwj zoo li no feem ntau yog ua los ntawm cov khoom siv PE thiab siv rau hauv cov tshuaj pleev ib ce xws li lub raj mis ua npuas ncauj, tshuaj pleev lub cev, tshuaj zawv plaub hau thiab tshuaj pleev ib ce.

Qhov thib ob yog kev txhaj tshuaj tshuab, uas muaj ob kauj ruam tseem ceeb: txhaj- tshuab moulding.

Kauj Ruam 1: Preform txhaj-pwm kaw.

Siv cov txheej txheem txhaj tshuaj molding los tsim ib qho kev sib tw hauv qab, thiab lub console tig 120 ° rau lub tshuab molding txuas.

Cov pwm raug kaw, thiab compressed cua yog nkag mus rau hauv lub parison los ntawm mandrel pores rau tshuab molding.

Kauj Ruam 2: Preform inflation-txias thiab demoulding.

Tom qab lub tshuab molded khoom yog kho kom zoo thiab molded, lub console tig 120 ° rau demold cov khoom.Tsis tas yuav tsum tau ua rau theem nrab trimming, yog li cov degree ntawm automation thiab ntau lawm efficiency yog siab.Vim tias lub raj mis tau tshuab los ntawm kev txhaj tshuaj molded parison, lub qhov ncauj ntawm lub raj mis yog tiaj tus thiab lub raj mis muaj cov khoom sib khi zoo dua, xws liTB07 tshuab raj series.

Hom thib peb yog sau ntawv rub thiab tshuab.Nws tau muab faib ua peb kauj ruam: txhaj tshuaj-stretching- tshuab moulding.

Sib txawv los ntawm hom turntable ntawm txhaj tshuaj tshuab, txhaj tshuaj stretch tshuab yog kev sib dhos kab ntau lawm.

Kauj Ruam 1: Preform txhaj-pwm kaw

Muab cov preform uas tsim los ntawm kev txhaj tshuaj rau hauv lub tshuab pwm

Ntxig tus pas nrig thiab kaw cov pwm sab laug thiab sab xis

Kauj Ruam 2: Stretching-Blowing-Cooling thiab demoulding

Lub stretching pas nrig yog longitudinally stretched, thaum huab cua yog txhaj los ntawm lub stretching pas nrig rau lateral stretching

Txias thiab shaping, demoulding thiab tshem tawm cov khoom

Txhaj ncab tshuab yog qhov zoo tshaj plaws, precision thiab tus nqi hauv cov txheej txheem tshuab molding.

Tam sim no, muaj ob txoj hauv kev hauv kev txhaj tshuaj stretch tshuab, hu ua: ib-kauj ruam txoj kev thiab ob-kauj ruam txoj kev.Kev txhaj tshuaj molding thiab tshuab molding yog ua tiav ua ke hauv ib kauj ruam, thiab ob kauj ruam ua tiav ntawm nws tus kheej raws li ob kauj ruam.

Piv nrog rau ob-kauj ruam txoj kev, ib-kauj ruam txoj kev yog ua tiav nyob rau hauv ib-kauj ruam cov cuab yeej los ntawm raw cov ntaub ntawv mus rau cov khoom tiav.Cov txheej txheem ntau lawm yog qhov yooj yim thiab tsis muaj cua sov thib ob raug tso cai, yog li kev siv hluav taws xob qis dua.

Txoj kev ob-kauj ruam yuav tsum tau txhaj tshuaj thawj zaug, thiab tom qab ntawd ua haujlwm thib ob ntawm lub tshuab moulding tshuab.Tshuab moulding yuav tsum tau cua sov thib ob ntawm lub txias preform, yog li lub zog noj yog siab.
