GMT Roj Teeb Pob Hauv Shield Pwm

GMT (Glass Mat Reinforced Thermoplastic) roj teeb pob nyob rau hauv cov ntaub thaiv npog pwm yog ib qho tshwj xeeb compression molding cuab yeej tsim tshwj xeeb rau cov qauv kev tiv thaiv ntawm lub zog tshiab lub tsheb roj teeb pob. Siv cov khoom tseem ceeb ntawm GMT cov ntaub ntawv-Lub teeb yuag, siab zog, cuam tshuam tsis kam, thiab rov ua dua tshiab-cov pwm no siv lub siab- qhov kub thiab txias, siab - cov txheej txheem kev sib xyaw ua ke kom nruj GMT cov ntawv rau hauv cov ntaub thaiv npog nyuaj uas ua tau raws li chassis installation. Nws ua haujlwm raws li cov kev daws teeb meem tseem ceeb uas sib npaug ntawm kev txhim kho lub teeb yuag ntawm lub zog tshiab tsheb thiab kev tiv thaiv tag nrho ntawm roj teeb kev nyab xeeb.

 

I.Core nta thiab qhov zoo

Cov khoom muaj zog Compatibility:Precisely matched nrog GMT nplooj ntawv raws li PP thiab lwm yam thermoplastic matrices, sib xws nrog mainstream iav fiber cov ntsiab lus specifications ntawm 25% -40%, kom tag nrho plasticization thiab ruaj khov molding ntawm cov ntaub ntawv.

 

Advanced Moulding txheej txheem:Txais cov txheej txheem compression molding zoo, nrog cov txheej txheem ua haujlwm: GMT daim ntawv preheating → ceev tuag kaw thiab nias → Thaum tshav kub kub preservation thiab siab tswj rau plasticization → txias thiab teeb → ruaj khov ejection.Cov txheej txheem yog compact nrog muaj zog controllability.

 

Core Performance Advantages:

High-kev ua tau zoo Mass Production: Lub voj voog luv molding, tsuas yog 60-90 vib nas this ib thooj, ua tau raws li qhov xav tau ntawm cov khoom loj loj.

 

High-Structure muaj zog:Cov khoom molded nta zoo heev rigidity, zoo heev cuam tshuam tsis kam thiab qaug zog kev ua tau zoo, zoo tiv thaiv chassis cuam tshuam thiab kev tiv thaiv kev nyab xeeb roj teeb.

 

Zoo kawg nkaus Lightweight Effect:Cov khoom ntom ntom tsuas yog 1.1-1.3 g / cm³, ua tiav qhov hnyav ntawm 40% -60% piv nrog cov ntaub thaiv hlau tsoos, pab tsheb txo kev siv zog thiab txhim kho kev tsav tsheb.

 

Ntsuab thiab Environmentally Friendly:GMT cov ntaub ntawv tuaj yeem siv tau 100% rov siv dua thiab rov siv dua, nyob rau hauv txoj kab nrog cov qauv tseem ceeb ntawm kev tsim ntsuab ntsuab thiab qis - carbon kev loj hlob hauv kev lag luam tsheb.

 

 

II.Mould Structure thiab Design Key Points

1. Main Pwm Qauv

Pwm Base System:Txais yuav ib qho hnyav hnyav- qauv qauv, ua los ntawm siab - lub zog steel xws li P20 thiab 718H. Nws tuaj yeem tiv taus siab -siab molding yuav tsum tau ntawm 10-20MPa, kom tsis txhob deformation thiab ruaj khov precision thaum siv mus ntev.

Txoj Kev Cavity:

Core thiab Cavity:: Machined ntawm precision xov kom haum rau txoj kev nkhaus nto ntawm daim ntaub thaiv npog. Qhov tseeb polishing nto mus txog Ra 0.8-1.6μm, lav qhov khoom du, tsis muaj qhov tsis xws luag.

Parting Line: Kev tshawb fawb thiab tsim nyog tsim los sib npaug sealing kev ua tau zoo thiab demoulding smoothness, zoo txo ​​flash tiam.

Draft Angle: Teem lub kaum sab xis ntawm 3℃-5℃kom tsis txhob khawb qhov chaw ntawm GMT cov khoom thaum lub sij hawm demoulding, kom ntseeg tau tias cov khoom tsim nyog tus nqi.

Kev taw qhia thiab qhov chaw: Nruab nrog precision qhia pins, qhia bushes thiab positioning pins kom raug tswj pwm kaw qhov sib txawv, xyuas kom pwm kaw precision, thiab ntxiv optimize flash tswj nyhuv.

 

2. Thermal Management System (Core Design)

Cua sov System:Nruab nrog ua - nyob rau hauv hluav taws xob cua sov raj los yog roj cua kub li, nws muaj peev xwm ua tau raws li qhov kub thiab txias tswj nyob rau hauv thaj tsam ntawm 150-220℃raws li GMT cov khoom specifications, xyuas kom meej tag nrho cov plasticization ntawm cov khoom.

Txias System:Txais yuav ib tug conformal cua txias channel tsim, uas tuaj yeem ua kom txias cov khoom pwm kom qis dua 60-80 degree, ua rau lub voj voog molding zoo heev thiab txhim kho kev tsim khoom.

Kub tswj qhov tseeb:Kev tswj qhov kub thiab txias yog tswj tsis pub dhau ± 5 degree, kom ntseeg tau tias cov khoom zoo li qub thiab ruaj khov kho ntawm cov khoom, thiab lav cov khoom zoo ib yam.

 

3. Kev Pabcuam Systems

Exhaust System:Precisely machined pa grooves yog qhib rau ntawm txoj kab parting kom zoo tso pa tawm hauv cov kab noj hniav thiab volatiles generated thaum lub sij hawm molding txheej txheem, tiv thaiv tsis xws luag xws li cov khoom tsis txaus thiab cua qhov nyob rau hauv cov khoom.

Ejection System:Txais yuav cov qauv ua ke ntawm ejector pins thiab ejector daim hlau kom ua tiav qhov ejection ruaj khov ntawm - cheeb tsam molded qhov chaw, tiv thaiv deformation thiab kev puas tsuaj ntawm cov khoom.

Integrated Functions:Qee cov pwm tau koom ua ke nrog kev txiav los yog xuas nrig ntaus kom paub txog "ib qho pwm, ob txheej txheem", txo cov txheej txheem tom ntej thiab txhim kho kev tsim khoom.
