Pulp molding, raws li tus neeg sawv cev ntim khoom nrov, yog nyiam los ntawm cov tswv lag luam. Nyob rau hauv cov txheej txheem ntawm cov khoom siv pulp molded, cov pwm, raws li cov khoom tseem ceeb, muaj cov kev cai siab rau kev txhim kho thiab tsim, kev nqis peev siab, lub voj voog ntev, thiab muaj kev pheej hmoo siab. Yog li, dab tsi yog cov ntsiab lus tseem ceeb thiab kev ceev faj hauv kev tsim cov ntawv yas pwm? Hauv qab no, peb yuav qhia qee qhov kev paub hauv kev ntim cov qauv tsim rau koj los kawm thiab tshawb nrhiav pulp molding pwm tsim.
01Kev tsim pwm
Cov qauv tsim muaj cov pwm convex, concave pwm, mesh pwm, pwm pwm, pwm rov qab kab noj hniav, thiab cua chamber. Lub mesh pwm yog lub cev tseem ceeb ntawm pwm. Raws li cov pwm mesh yog woven los ntawm cov hlau los yog yas xov hlau nrog ib txoj kab uas hla ntawm 0.15-0.25mm, nws tsis tuaj yeem tsim nws tus kheej thiab yuav tsum tau txuas rau saum npoo ntawm cov pwm ua haujlwm.
Cov kab noj hniav tom qab ntawm pwm yog cov kab noj hniav uas tsim los ntawm qee qhov tuab thiab cov duab uas yog synchronized tag nrho nrog kev ua haujlwm ntawm pwm, txheeb ze rau lub rooj zaum pwm. Lub convex thiab concave pwm yog ib lub plhaub nrog ib tug tej phab ntsa thickness. Qhov chaw ua hauj lwm ntawm cov pwm yog txuas nrog cov kab noj hniav tom qab los ntawm cov qhov sib faib me me.
Cov pwm yog ntsia rau ntawm tus qauv ntawm lub tshuab molding los ntawm lub rooj zaum pwm, thiab lub tshuab cua yog nruab rau ntawm sab nraud ntawm lub template. Cov cua chamber txuas nrog rau sab nraub qaum, thiab tseem muaj ob txoj hauv kev rau compressed cua thiab lub tshuab nqus tsev rau nws.
02 ibShaping pwm
Cov pwm shaping yog cov pwm uas ncaj qha nkag mus rau hauv daim ntawv ntub dej tom qab tsim thiab muaj cov haujlwm ntawm cua sov, pressurization, thiab lub cev qhuav dej. Cov khoom tsim nrog cov pwm shaping muaj ib tug du nto, yog qhov ntev, solidity, thiab zoo rigidity. Cov khoom siv pov tseg pov tseg yog tsim los ntawm cov pwm no. Hauv kev ntim khoom lag luam, qee qhov me me, meej, thiab ntau ntawm cov khoom me me tau ntim cov txheej txheem los ntawm txheej, nrog rau cov khoom ntim khoom siv rau qhov chaw ntawm txhua txheej. Yog tias siv cov khoom siv molded, lawv yuav tsum tau tsim los ntawm cov pwm molding.
Txawm li cas los xij, feem ntau cov khoom ntim khoom lag luam ua haujlwm ntawm ib sab thiab tsis tas yuav tsum tau ua kom sov. Lawv tuaj yeem qhuav ncaj qha. Cov qauv ntawm cov pwm shaping muaj xws li cov pwm convex, concave pwm, mesh pwm, thiab cov khoom cua sov. Lub convex los yog concave pwm nrog ib tug mesh pwm muaj cov kua thiab tso qhov. Thaum lub sijhawm ua haujlwm, daim ntawv ntub dej yog thawj zaug hauv lub puab pwm, thiab 20% ntawm cov dej yog nyem thiab tawm. Lub sijhawm no, cov ntsiab lus dej ntawm cov ntawv ntub dej yog 50-55%, uas ua rau cov dej seem tom qab cov ntawv ntub dej yog cua sov hauv pwm kom vaporized thiab tawm. Daim ntawv ntub dej yog nias, qhuav, thiab zoo li tus tsim cov khoom.
Lub mesh pwm nyob rau hauv lub molding pwm tuaj yeem ua rau mesh cov cim rau ntawm qhov chaw ntawm cov khoom, thiab cov pwm mesh tuaj yeem ua kev puas tsuaj sai heev thaum lub sij hawm extrusion. Yuav kom daws tau qhov teeb meem no, tus tsim pwm tsim tau tsim ib qho mesh dawb pwm, uas yog tsim los siv tooj liab raws li cov hmoov metallurgy. Ob xyoos dhau los, tom qab ntau yam kev txhim kho thiab kev xaiv ntawm cov hmoov me me uas tsim nyog, lub neej ntev ntawm cov mesh dawb shaping pwm tsim yog 10 npaug ntawm cov mesh pwm, nrog rau 50% tus nqi txo. Cov khoom siv ntawv tsim muaj siab precision thiab du sab hauv thiab sab nrauv.
03Kub Pressing Pwm
Tom qab ziab, daim ntawv ntub dej tsis muaj deformation. Thaum qee qhov chaw raug deformation hnyav los yog xav tau siab precision nyob rau hauv cov tsos ntawm cov khoom, cov khoom undergoes ib tug shaping txheej txheem, thiab cov pwm siv yog hu ua shaping pwm. Cov pwm no kuj xav tau cov khoom cua sov, tab sis nws tuaj yeem ua tau yam tsis muaj pwm mesh. Cov khoom uas xav tau shaping yuav tsum khaws cov dej noo ntawm 25-30% thaum ziab kom yooj yim shaping.
Hauv kev xyaum ntau lawm, nws yog qhov nyuaj rau kev tswj cov dej ntsiab lus, uas ua rau nws nyuaj rau cov khoom kom tau raws li qhov yuav tsum tau ua. Ib lub chaw tsim khoom tau tsim cov tshuaj tsuag shaping pwm, thiab cov tshuaj tsuag qhov ua rau ntawm cov pwm sib raug rau cov khoom uas xav tau shaping. Thaum ua haujlwm, cov khoom raug muab tso rau hauv pwm pwm tom qab kom qhuav. Nyob rau tib lub sijhawm, cov tshuaj tsuag qhov ntawm cov pwm yog siv rau cov tshuaj tsuag kub nias cov khoom. Cov pwm no zoo ib yam li cov tshuaj tsuag hlau hauv kev lag luam khaub ncaws.
04 ibHloov Pwm
Cov pwm hloov pauv yog qhov chaw ua haujlwm kawg ntawm tag nrho cov txheej txheem, thiab nws lub luag haujlwm tseem ceeb yog kom muaj kev nyab xeeb hloov cov khoom los ntawm cov khoom siv pwm pwm mus rau lub tais tau txais. Rau kev hloov pwm, nws cov qauv tsim yuav tsum yooj yim li sai tau, nrog cov txheej txheem nqus cov qhov sib npaug los xyuas kom meej tias cov khoom tuaj yeem ua kom zoo adsorb ntawm pwm nto.
05Trimming Pwm
Txhawm rau ua cov ntawv molded cov khoom kom huv si thiab zoo nkauj, cov ntawv molded cov khoom uas zoo li yuav tsum tau nruab nrog ntug txiav txheej txheem. Tuag txiav pwm yog siv los txiav cov npoo ntxhib ntawm cov ntawv molded cov khoom, tseem hu ua ntug txiav pwm.
