Dab tsi yog qhov sib txawv ntawm insert molding thiab cladding molding?

1, Txheej txheem txhais thiab cov hauv paus ntsiab lus
Ntxig molding yog txheej txheem molding uas embeds preformed qhov chaw (feem ntau yog hlau los yog lwm yam ntaub ntawv nyuaj) rau hauv pwm, thiab ces txhaj cov khoom yas los ua ke nrog cov ntxig rau hauv cov khoom sib xyaw. Cov txheej txheem no tso cai rau cov neeg tsim qauv thiab cov kws tsim qauv tsim kom muaj kev sib koom ua ke ntawm cov hlau ntxig (xws li threaded inserts, cov khoom siv hluav taws xob, thiab lwm yam) rau hauv cov khoom yas, yog li txhim kho lub zog ntawm cov qauv, conductivity, lossis lwm yam khoom tshwj xeeb ntawm cov khoom.
Encapsulation molding yog txheej txheem molding uas ib los yog ntau tshaj molten plastics raug txhaj rau hauv pwm thiab npog mus rau ib qho khoom siv uas twb muaj lawm (uas tuaj yeem yog yas, hlau, lossis lwm yam ntaub ntawv) los tsim ib qho kev tivthaiv. Encapsulation molding tuaj yeem siv ntau yam ntaub ntawv xws li yas encapsulation, mos roj hmab encapsulation, los yog mos roj hmab encapsulation, ua tau ib tug nruj kev sib raug zoo ntawm cov ntaub ntawv sib txawv los ntawm lub cev snap fasteners los yog tshuaj bonding.
2, Kev xaiv cov khoom siv thiab cov qauv tsim
Cov khoom xaiv rau ntxig molding yog qhov hloov tau yooj yim. Lub ntxig tuaj yeem yog hlau (xws li tooj dag, hlau, stainless hlau, thiab lwm yam), ceramic, iav, lossis lwm yam khoom siv tawv, thaum lub hnab yas tuaj yeem xaiv ntau hom thermoplastic resins raws li cov kev xav tau tshwj xeeb. Nyob rau hauv cov nqe lus ntawm cov qauv tsim, ntxig molding yuav tsum muaj kev sib txuas zoo ntawm qhov ntxig thiab cov yas kom ntseeg tau tias lawv tuaj yeem raug kaw nruj nreem thaum lub sijhawm molding txheej txheem, tsis txhob muaj qhov khoob lossis delamination.
Encapsulation molding tsom ntau dua ntawm cov tshuaj sib txuas los yog lub cev sib cuam tshuam ntawm cov khoom sib txawv. Yuav kom ua tiav lub hom phiaj no, encapsulation molding feem ntau xaiv cov khoom sib txuas nrog zoo sib xws thiab adhesion. Piv txwv li, los ntawm kev kho cov mis ntawm cov ntaub ntawv yas los tsim cov tshuaj tiv thaiv nrog cov substrate, tag nrho lub zog thiab durability ntawm cov khoom tuaj yeem txhim kho. Hauv kev tsim qauv, qhov sib txawv ntawm kev nthuav dav coefficient ntawm cov ntaub ntawv yuav tsum tau txiav txim siab rau encapsulation molding kom tsis txhob muaj kev ntxhov siab lossis tawg thaum lub sijhawm molding.
3, Cov Txheej Txheem Ntau Lawm thiab Kev Tswj Xyuas Zoo
Cov txheej txheem ntawm kev ntxig molding yog qhov nyuaj, yuav tsum tau muab tso rau hauv cov pwm kom raug thiab xyuas kom meej tias lawv nyob hauv qhov chaw thaum txhaj tshuaj yas. Qhov no feem ntau yuav tsum tau siv cov cuab yeej tshwj xeeb ntsug txhaj tshuaj molding tshuab los yog cov tshuab siv tshuab kom tswj tau qhov chaw thiab qhov chaw ntawm cov khoom siv. Tsis tas li ntawd, kev tswj xyuas nruj ntawm qhov kub thiab kev txhaj tshuaj siab ntawm cov khoom siv yas yog yuav tsum tau rau kev ntxig molding kom ntseeg tau tias cov yas tuaj yeem ua tiav cov pwm thiab nruj nreem qhwv ib ncig ntawm cov ntxig. Nyob rau hauv cov nqe lus ntawm kev tswj kom zoo, ntxig molding yuav tsum tau saib xyuas lub zog ntawm kev sib txuas ntawm cov ntxig thiab cov yas, qhov tseeb qhov tseeb ntawm cov khoom, thiab qhov zoo ntawm qhov chaw.
Cov txheej txheem ntawm cov txheej txheem molding yog qhov yooj yim, tab sis nws tseem yuav tsum tau them sai sai rau kev sib raug zoo thiab adhesion ntawm cov ntaub ntawv. Thaum lub sij hawm molding txheej txheem, nws yog ib qho tsim nyog los xyuas kom meej tias cov khoom yas muaj peev xwm sib npaug ntawm cov substrate thiab tsim cov txheej txheem zoo. Tsis tas li ntawd, nws yuav tsum tau them sai sai rau lub shrinkage tus nqi thiab deformation ntawm cov khoom thaum lub sij hawm encapsulation molding kom tsis txhob muaj qhov sib txawv ntawm qhov sib txawv los yog cov duab distortions. Nyob rau hauv cov nqe lus ntawm kev tswj kom zoo, encapsulation molding yuav tsum tau them sai sai rau cov tsos zoo, kev sib khi lub zog, thiab huab cua tsis kam ntawm cov khoom.
4, Daim Ntawv Thov Fields thiab Kev Ua Lag Luam Zoo
Embedded molding yog dav siv nyob rau hauv ntau yam lag luam xws li tsheb, kho mob, hluav taws xob, thiab cov khoom siv. Hauv kev lag luam automotive, ntxig molding yog siv los tsim cov khoom siv cav, chassis, thiab cov khoom sab hauv; Hauv kev lag luam kho mob, ntxig molding yog siv los tsim cov cuab yeej phais, kev cog qoob loo, thiab cov khoom siv kho mob casings; Hauv kev lag luam hluav taws xob, ntxig molding yog siv los tsim cov khoom siv hluav taws xob xws li casings thiab connectors. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev txo qis ntawm cov nqi, daim ntawv thov kev cia siab ntawm kev ntxig molding hauv ntau thaj chaw yuav yog qhov dav dua.
Encapsulation molding feem ntau yog siv rau hauv cov xwm txheej uas tsim nyog los txhim kho cov khoom zoo nkauj, txhim kho lub zog ntawm cov qauv, lossis ua tiav cov haujlwm tshwj xeeb. Piv txwv li, hauv cov khoom siv hluav taws xob, encapsulation molding yog siv los tsim cov khoom xws li cov xov tooj, cov keyboards, thiab saib ciam teb; Hauv cov khoom siv hauv tsev, overmolding yog siv los tsim cov khoom xws li cutlery handles thiab khob hau los txhim kho kev nplij siab thiab kav ntev. Nrog rau kev txhim kho txuas ntxiv ntawm cov neeg siv khoom xav tau rau cov khoom lag luam zoo thiab tsim qauv, daim ntawv thov txheej txheem ntawm encapsulation molding tseem yuav nthuav dav ntxiv.
