Kev faib tawm tseem ceeb ntawm cov pwm yas
Raws li kev sib txawv molding, cov yas ua pwm tuaj yeem muab faib ua ntau hom sib txawv raws li cov txheej txheem sib txawv. Cov no feem ntau suav nrog kev txhaj tshuaj molding, extrusion molding pwm, nqus cov pwm pwm, thiab siab - ntom polystyrene molding pwm.
1. Yas Txhaj Moulds
Cov no yog cov feem ntau siv molding pwm nyob rau hauv zus tau tej cov thermoplastic qhov chaw. Cov khoom siv rau kev txhaj tshuaj yas pwm yog lub tshuab yas txhaj tshuaj molding. Cov yas yog thawj rhuab thiab yaj nyob rau hauv lub qhov cub cua sov nyob rau hauv qab ntawm lub tshuab txhaj tshuaj. Tom qab ntawd, tsav los ntawm cov ntsia hlau lossis plunger ntawm lub tshuab txhaj tshuaj, nws nkag mus rau hauv pwm kab noj hniav los ntawm kev txhaj tshuaj nozzle thiab pwm qhov rooj kaw lus. Cov yas cools thiab hardens, thiab cov khoom yog tau los ntawm demolding. Nws cov qauv feem ntau muaj cov molding Cheebtsam, lub rooj vag system, kev taw qhia Cheebtsam, ib tug ejection mechanism, ib tug kub tswj qhov system, ib tug venting system, thiab txhawb cov khoom. Cov khoom siv feem ntau yog cov yas pwm hlau, nrog rau cov khoom siv feem ntau suav nrog cov qauv hlau, cov cuab yeej carbon steel, cov cuab yeej hlau alloy, thiab siab - steel ceev. Kev txhaj tshuaj molding feem ntau tsuas yog tsim nyog rau kev tsim cov khoom siv thermoplastic. Cov khoom siv yas uas tsim los ntawm kev txhaj tshuaj molding muaj ntau yam sib txawv, xws li cov khoom siv niaj hnub mus rau cov tshuab ua haujlwm, cov khoom siv hluav taws xob, thiab cov khoom siv thauj mus los. Nws yog txoj kev siv ntau tshaj plaws hauv kev tsim khoom yas.
2. Yas Compression Pwm
Cov no suav nrog ob hom pwm: compression molding thiab txhaj tshuaj molding. Lawv feem ntau yog siv los pwm thermosetting yas, thiab cov khoom siv sib xws yog lub tshuab compression molding. Nyob rau hauv compression molding, raws li cov khoom ntawm cov yas, cov pwm yog rhuab mus rau molding kub (feem ntau 103℃-108 degree). Tom qab ntawd, metered compression molding hmoov yog muab tso rau hauv lub pwm kab noj hniav thiab pub chamber. Cov pwm raug kaw, thiab cov yas softens thiab ntws nyob rau hauv high kub thiab siab, solidifying thiab teeb tsa tom qab ib tug tej lub sij hawm los tsim cov yam khoom uas xav tau. Txhaj tshuaj molding txawv ntawm compression molding nyob rau hauv uas nws muaj ib tug cais chav noj mov. Ua ntej molding, pwm raug kaw, thiab cov yas yog preheated thiab ua viscous nyob rau hauv lub chamber pub. Nyob rau hauv siab, nws yog ces extruded rau hauv pwm kab noj hniav thiab hardened. Compression pwm kuj tseem siv los pwm qee yam tshwj xeeb thermoplastics, xws li nyuaj- rau- melting thermoplastics (xws li, polyvinyl fluoride) blanks (txias pressing), siab - kho qhov muag- kev ua tau zoo resin lo ntsiab muag, thiab me ntsis foamed nitrocellulose automotive steering. Compression pwm feem ntau muaj cov kab noj hniav, noj kab noj hniav, kev taw qhia mechanism, ejection Cheebtsam, thiab cua sov system. Txhaj pwm yog dav siv nyob rau hauv encapsulation ntawm cov khoom siv hluav taws xob. Cov ntaub ntawv siv hauv kev tsim cov pwm compression yog qhov pib zoo ib yam li cov siv hauv kev txhaj tshuaj pwm.
3. Yas Extrusion Pwm
Cov no yog cov pwm siv los tsim cov khoom txuas ntxiv -plastics, kuj hu ua extrusion tuag hau. Lawv tau siv dav hauv kev ua cov kav dej, pas nrig, monofilaments, nplooj ntawv, zaj duab xis, xaim thiab cable sheathing, thiab profiles. Cov khoom siv sib xyaw ua ke yog cov yas extruder. Lub hauv paus ntsiab lus yog tias cov khoom yas melts thiab plasticizes nyob rau hauv cua sov thiab siab los ntawm lub rotating ntsia hlau ntawm lub extruder, thiab ces dhau los ntawm ib tug tuag ntawm ib tug tshwj xeeb cov duab los tsim cov khoom yas txuas ntxiv nrog tib tus ntoo khaub lig-section raws li qhov tuag. Cov ntaub ntawv tseem ceeb uas siv rau hauv lawv cov khoom siv xws li carbon structural steel thiab alloy cov cuab yeej. Qee cov pwm extrusion kuj muaj hnav- cov ntaub ntawv tiv taus xws li pob zeb diamond embedded rau hauv qhov chaw uas yuav tsum tau hnav tsis kam. Extrusion molding txheej txheem feem ntau tsuas yog siv rau kev tsim cov khoom siv thermoplastic, thiab lawv cov qauv sib txawv ntawm cov pwm txhaj tshuaj thiab compression pwm.
4. Yas Tshuab Moulding Pwm
Cov pwm no yog siv los tsim cov thawv yas hollow (xws li lub raj mis dej haus, cov khoom siv tshuaj txhua hnub, thiab ntau lub thawv ntim khoom). Tshuab moulding txoj kev, raws li lawv cov txheej txheem txheej txheem, feem ntau suav nrog extrusion tshuab moulding, txhaj tshuaj molding, txhaj stretch tshuab moulding (feem ntau hu ua "txhaj ncab tshuab"), multi- txheej tshuab moulding, thiab ntawv tshuab moulding. Cov cuab yeej siv rau tshuab moulding hollow cov khoom feem ntau hu ua yas tshuab moulding tshuab. Tshuab moulding tsuas yog tsim rau kev tsim cov khoom siv thermoplastic. Tshuab moulding pwm muaj cov qauv yooj yim, thiab cov ntaub ntawv siv feem ntau yog carbon fiber.
5. Lub tshuab nqus tsev tsim pwm
Hom pwm no siv cov ntawv yas los yog daim hlau ua cov khoom siv los tsim cov khoom yas yooj yim. Lub hauv paus ntsiab lus yog siv lub tshuab nqus tsev los yog compressed cua molding kom deform cov ntawv yas los yog phaj, uas yog tsau rau lub concave los yog convex pwm, thiab tom qab ntawd ua raws li cov pwm kab noj hniav kom tau cov khoom xav tau. Nws yog tsuas yog siv rau hauv kev tsim cov khoom ntim khoom siv niaj hnub, khoom noj, thiab cov khoom ua si. Vim tias lub siab ua haujlwm tsawg, lub tshuab nqus tsev pwm feem ntau yog ua los ntawm cam khwb cia txhuas lossis tsis yog-cov ntaub ntawv hlau, uas ua rau muaj cov qauv yooj yim.
6. Siab -Expansion Polystyrene Moulding Pwm
Hom pwm no siv cov polystyrene nthuav dav (ib lub hlaws-zoo li cov khoom siv los ntawm polystyrene thiab foaming agent) los tsim ntau yam khoom ntawm cov ntaub ntawv ntim yas. Lub hauv paus ntsiab lus yog qhov nthuav dav polystyrene tuaj yeem ua rau chav - tsim hauv pwm. Muaj ob hom: yooj yim phau ntawv pwm thiab hydraulic xovxwm ncaj qha -flow foam yas pwm. Cov no tsuas yog siv los tsim cov khoom ntim khoom siv rau kev lag luam. Cov khoom siv los tsim cov pwm no muaj xws li cam khwb cia txhuas, stainless hlau, thiab tooj dag.
