Petg Txhaj Molding

PETG txhaj tshuaj molding yog ib qho kev siv tshuab uas ua rau cov khoom siv tuab- cov khoom siv phab ntsa, pob tshab thiab tso cai rau kev tsim qauv tsim thiab nthuav dav. Kev tsim khoom ntau dua thiab cov nqi tsim khoom qis dua tuaj yeem pom tau tias piv rau qee yam khoom siv.

PETG, uas sawv cev rau polyethylene terephthalate glycol- hloov kho, yog ib qho zoo heev thermoplastic rau kev txhaj tshuaj molding daim ntawv thov uas xav tau siab clarity, lub zog, tshuaj tiv thaiv thiab kav ntev. Nws lub peev xwm los txhaj tshuaj molded rau hauv cov geometry complex ua rau nws haum rau ntau yam khoom thoob plaws kev kho mob, electronics, ntim thiab cov neeg siv khoom lag luam.

Plasticity
Cov khoom siv PETG muaj cov yas muaj zog thiab yoog raws, nrog qee yam zoo li -cov yam ntxwv nco. Qhov no tso cai rau kev tsim ntau yam khoom tsim, ua rau nws tsim nyog rau cov khoom uas xav tau cov qauv tsim thiab cov ntaub ntawv sib txawv.

Siab Transparency
PETG muab cov pob tshab zoo thiab lub teeb xa tawm. Qee cov ntaub ntawv tuaj yeem ua tiav lub teeb xa hluav taws xob txog li 90%, muab cov khoom siv lead ua rau nws zoo li ci ntsa iab -. Nws cov tawv tawv tshaj li ntawm acrylic, ua rau nws zoo tagnrho rau kev tsim cov khoom yas pob tshab.

Impact Resistance
Qhov cuam tshuam toughness ntawm PETG yog qhov zoo tshaj plaws, mus txog lossis txawm tias dhau ntawm polycarbonate. Nws tuaj yeem nyob twj ywm tsis muaj kev puas tsuaj rau lub sijhawm txuas ntxiv hauv siab -lub zog, siab - qhov chaw siab.

Environmental Friendliness
PETG yog cov khoom siv rov ua dua tshiab. Thaum hlawv tag, nws tsuas yog tawm tom qab CO2 (carbon dioxide) thiab dej, txo cov pa phem ib puag ncig thiab cov peev txheej pov tseg thaum rov ua dua thiab rov tsim dua tshiab.

Yog lawm, PETG tuaj yeem raug txhaj tshuaj molded los tsim qhov nyuaj, pob tshab rau ntau daim ntawv thov. Qhov tseeb, kev txhaj tshuaj molding yog ib qho ntawm ntau tshaj plaws thiab tus nqi - cov txheej txheem tsim tau zoo rau kev ua haujlwm nrog PETG yas.
Cov txheej txheem thermoplastic thiab yaj- ntws cov khoom ntawm PETG ua rau nws yog tus neeg sib tw zoo tshaj plaws rau kev txhaj tshuaj molding. PETG yooj yim ntws mus rau hauv cov pwm geometries thiab kho kom ruaj khov kawg - siv cov khoom.

Kev txhaj tshuaj molding txheej txheem rau PETG muaj peb kauj ruam tseem ceeb:

1. PETG yas pellets yog nqus los ntawm lub hopper rau hauv lub tshuab txhaj tshuaj molding lub thoob.

Lub thoob yog rhuab kom yaj PETG mus rau hauv lub xeev ua kua uas tau yooj yim ntws mus rau hauv pwm kab noj hniav.

2. Lub molten PETG yog txhaj ntawm tus nqi tswj thiab siab rau hauv cov pwm txhaj tshuaj.

Ob lub puab tsaig ntawm cov pwm yog tuav ua ke nyob rau hauv siab los tiv thaiv cov khoom to. PETG siv cov duab thaum nws txias thiab kho hauv pwm.

3. Thaum kho, cov pwm sib cais thiab txhaj tshuaj molded PETG ib feem yog ejected tawm. Cov sprues thiab cov neeg khiav dej num - cov yas kho ntau dhau los ntawm pwm - raug txiav tawm ntawm qhov.

Tom qab tshem tawm, qee qhov kev tshaj tawm ntxiv -moulding lwm yam kev ua haujlwm yuav ua tau zoo ib yam. Qhov no suav nrog kev kho kom zoo nkauj, tsim khoom lag luam lossis sib sau ua ke ntau yam yas ua ke.

Tshuab ntxuav

Ua ntej txhaj tshuaj molding nrog PETG yas, nws yog ib qho tseem ceeb uas yuav tau ntxuav lub tshuab siv pob tshab PC los yog PS cov ntaub ntawv los yog ib tug tshwj xeeb ntsia hlau tu tus neeg saib xyuas. Tsis txhob siv lwm cov ntaub ntawv pob tshab xws li PMMA, ABS, lossis AS los ntxuav; txwv tsis pub, tshuaj lom neeg cov tshuaj tiv thaiv yuav tshwm sim nyob rau hauv lub thoob, ua rau cov khoom discoloration thiab opacity.

Tshuab ziab khaub ncaws

Nws yog ib qho tseem ceeb uas yuav tau txais cov txheej txheem ziab kom zoo tshaj plaws los tiv thaiv PETG qhov chaw los ntawm kev qhia tsis xws li haziness, splay, thiab tawg. Nws raug nquahu kom siv lub tshuab dehumidifying muaj peev xwm ncav cuag -30℃dew point. Feem ntau, ntsuas qhov kub ntawm 60-65℃rau lub sijhawm ziab ntawm 4-6 teev.

Txhaj Ceev

Thaum pib ntawm kab noj hniav, nws tau hais kom siv qhov kev txhaj tshuaj ceev ntawm 10% mus rau 20%. Tom qab ntawd, maj mam nce qhov kev txhaj tshuaj nrawm mus rau 40% -80% txhawm rau ua kom tiav cov khoom ntxiv tom ntej, tiv thaiv qhov tsis xws luag xws li rooj vag cov cim lossis cov kab nrib pleb.

Lub sijhawm txias

PETG muaj qhov txias txias thiab nruab nrab viscosity. Qhov kub thiab txias lub sij hawm molding yuav tsum tau teem raws li cov qauv pwm thiab cov khoom thickness.

Lub sprue lub demolding lub kaum sab xis yuav tsum tau tsim ntawm 3-5 degree, los yog lwm yam sprue yuav lo rau pwm.

Complex geometry- Precision pwm tuaj yeem tsim cov duab sib txawv tsis tuaj yeem ua tau

Kev ua tau zoo- Automated huab hwm coj ntau lawm nrog lub voj voog nrawm dua thiab ua haujlwm qis dua

Kev sib raug zoo- Kev rov ua tau zoo dua qhov raug thiab kho tshuab
