Dab tsi yog qhov ob txhaj tshuaj overmolding?
Ob- txhaj tshuaj overmolding (tseem hu ua ob- txhaj tshuaj molding lossis 2K txhaj tshuaj molding) yog txheej txheem yas txhaj tshuaj molding uas muaj ob yam khoom sib txawv (lossis ob xim ntawm cov khoom siv tib yam) yog molded ua ke rau hauv ib feem ntawm ob theem ua ntu zus hauv ib lub voj voog molding thiab ib lub tshuab.
Ob txoj kev txhaj tshuaj overmolding yog dab tsi?
Thawj txhaj tshuaj (Substrate Formation)
Cov khoom siv hauv paus (feem ntau yog cov yas tawv zoo li ABS, PC, PA, lossis PBT) yog txhaj rau hauv pwm los tsim qhov pib substrate.
Qhov kev txhaj tshuaj thawj zaug no ua kom muaj zog txaus los tswj nws cov duab tab sis tseem tsim los rau kev sib raug zoo nrog cov khoom siv thib ob.
Pwm tig los yog Hloov
Cov pwm qhib thiab hloov pauv lub substrate, los ntawm kev tig cov pwm core, zawv zawg kab noj hniav, los yog hloov qhov chaw mus rau lwm qhov kab noj hniav hauv tib lub tshuab.
Qhov no tso lub substrate kom lwm cov kab noj hniav sib haum rau kev txhaj tshuaj thib ob.
Kev txhaj tshuaj thib ob (Overmold Injection)
Ib qho khoom siv thib ob (feem ntau yog cov yas softer xws li TPE, TPU, lossis qee zaum lwm cov tawv tawv tawv nrog cov xim sib txawv / cov yam ntxwv) raug txhaj tshuaj los yog ncig thawj zaug.
Txij li thaum ob qhov kev txhaj tshuaj tshwm sim nyob rau hauv ib ntus hauv tib lub voj voog, cov khoom siv thib ob txuas nrog cov khoom tseem - sov thawj cov khoom.
Cooling thiab Ejection
Ob qho khoom siv txias ua ke, tsim ib qho, sib koom ua ke mus tas li.
Cov khoom tiav yog ejected los ntawm pwm, npaj tsis muaj kev sib dhos ntxiv.
Qhov zoo ntawm ob txhaj tshuaj overmolding
Txhim kho cov khoom zoo thiab kev ua haujlwm zoo
Tshaj- molding ua kom muaj kev sib raug zoo thiab sib dhos nruj ntawm cov khoom sib txuas. lt txhim kho cov khoom zoo thiab kev ua haujlwm zoo.
Tshem tawm Fasteners thiab Adhesive
Overmolding qhov chaw tshem tawm qhov xav tau ntxiv rau fasteners lossis nplaum. Piv txwv li, ib tug txhuam hniav roj hmab tuav yog ob- txhaj molded nrog ib tug yas kov. Yog li overmolding tshem tawm cov kev xav tau nplaum.
Txo tus nqi
Yas overmolding tshem tawm kev siv cov kev ua haujlwm thib ob los txo cov nqi zog, lub sijhawm, thiab cov kev xav tau ntawm cov fasteners.
Txhim kho cov khoom ergonomics thiab siv kev paub
Overmolding tuaj yeem muab cov khoom siv roj hmab rau cov cuab yeej, txhuam hniav, thiab lwm yam khoom siv tes. Rubber grips pab txhim kho cov khoom ergonomics. Ob- txhaj tshuaj molding thiab co- txhaj tshuaj molding muaj kev siv hauv kev tsim khoom hauv ntau xim. Ntau xim txhim kho cov khoom zoo nkauj.
Txhim khu kev tsim Flexibility
Kev sib dhos yooj yim tsim thiab tsim khoom ntawm ntau- cov khoom siv yog ua tau nrog overmolding. Piv txwv li, lub tsheb headlights yog tsim los ntawm kev siv ntxig los yog ob - txhaj tshuaj molding.
Quality Control nyob rau hauv ob txhaj tshuaj overmolding
1. Kev Tswj Xyuas Khoom Zoo
Kev txheeb xyuas cov khoom siv sib xws - xyuas kom meej ob daim ntawv cog lus kom raug.
Kev tswj dej noo - ntau yam khoom siv yas (PC, PA, PBT) yog hygroscopic; ziab yog qhov tseem ceeb los tiv thaiv npuas los yog kev sib txuas tsis zoo.
Batch sib xws - xim, viscosity, thiab additive uniformity yuav tsum tau xyuas ua ntej ntau lawm.
2. Txheej txheem tswj
Kev tshuaj xyuas qhov ntsuas qhov ntsuas - qhov kub, siab, ceev, thiab lub sijhawm txias yuav tsum nruj tswj kom tsis txhob muaj kev sib tsoo, kub hnyiab, lossis ua tsis tiav.
Hloov qhov tseeb - yog tias siv cov rotating lossis zawv zawg pwm, kev sib raug zoo raug kuaj xyuas kom tsis txhob muaj teeb meem lossis tsis zoo.
Cycle sib xws - automated sensors thiab tshuab tawm tswv yim kom rov ua tau dua.
3. Bonding & Adhesion Zoo
tev lossis rub-tawm kev sim - xyuas kom muaj zog adhesion ntawm ob cov ntaub ntawv.
Hla -section soj ntsuam - microscopic lossis txiav-ib feem kuaj xyuas kom paub meej tias kev sib raug zoo ntawm kev sib txuas.
Kev tswj kev sib kis ntawm qhov chaw - xyuas kom tsis muaj plua plav, roj, lossis tso tawm cov neeg ua haujlwm thaiv adhesion.
4. Dimensional & Visual Inspection
Dimensional raug - siv CMM (Coordinate Measuring Machines) los yog optical scanners los xyuas qhov kam rau ua.
Flash, cov cim dab dej, warpage - kev kuaj pom lossis cov tshuab tsis pom kev pom pom cov teeb meem zoo nkauj / qauv.
Xim sib piv - txheeb xyuas ob - xim qhov chaw raws li qhov xav tau pom (tsis muaj los ntshav lossis tsis muaj xim).
5. Mechanical & Functional Testing
Kev cuam tshuam thiab kev ntsuam xyuas kev ntxhov siab - xyuas kom cov cheeb tsam overmolded tsis tawg nyob rau hauv load.
Kev ntsuam xyuas kev puas tsuaj - rau cov mos mos uas tuaj yeem hnav (xws li tuav).
Seal kev ncaj ncees - rau overmolds siv los ua gaskets los yog waterproof vaj tse.
6. Cov txheej txheem QC Advanced
Automated optical inspection (AOI) - kuaj pom qhov me me lossis xim tsis xws luag.
X-ray / CT scanning - rau cov geometry nyuaj, xyuas cov voids sab hauv lossis tsis tiav kev sib txuas.
Statistical process control (SPC) - saib xyuas qhov loj me thiab cov txheej txheem tsis dhau sijhawm.
