Hauv kev txhaj tshuaj molding,ob -ximthiabpeb -ximKev txhaj tshuaj molding yog hais txog kev txhaj tshuaj ob lossis peb xim sib txawv (lossis cov khoom sib txawv) ntawm cov yas molten rau hauv tib cov khoom yas. Hom txheej txheem no feem ntau yog siv los txhim kho kev zoo nkauj, kev ua haujlwm (xws li kev sib txuas cov yas tawv thiab mos), lossis cov nqi tsim khoom- ua tau zoo ntawm cov khoom.
I. Kev piav qhia ntxaws txog ob-Tsev Xim Txhaj Moulding Technology
Ob- xim txhaj tshuaj molding tshuab muab ob lub xim sib txawv lossis hom khoom siv yas los ntawm kev txhaj tshuaj molding los tsim cov khoom yas nrog ob xim sib txawv lossis cov khoom siv.
1. Thawj Xim Txhaj (Pib Txheej)
Ua ntej, thawj chav txhaj tshuaj ntawm lub tshuab txhaj tshuaj molding tshuab (feem ntau yog rau lub ntsiab lossis lub hauv paus xim) txhaj cov yas molten rau hauv pwm kab noj hniav, tsim cov qauv ntawm cov yas.
2. Pwm tig los yog zawv zawg txav (Reorientation)
Cov pwm rotates (kab rov tav / ntsug) los yog lub slider txav, txav lub hauv paus yas ib feem mus rau qhov thib ob xim txhaj tshuaj.
3. Kev Txhaj Tshuaj Thib Ob (Overlay)
Lub tshuab txhaj tshuaj thib ob txhaj cov yas molten ntawm cov xim thib ob rau hauv cov cheeb tsam tshwj xeeb ntawm lub hauv paus yas, ua tiav ib qho kev sib tshooj lossis cov xim sib txawv.
Cov Ntsiab Lus Tseem Ceeb:
Hauv ob- xim molding, lub zog tuav yog qhov tseem ceeb heev. Txhawm rau kom tsis txhob muaj delamination lossis flashing ntawm ob xim, ib qho kev tuav tuav yog feem ntau yuav tsum tau ua kom ntseeg tau tias ob cov ntaub ntawv tseem nyob ruaj khov thaum lub caij txias.
II.Kev piav qhia ntxaws txog peb - xim txhaj tshuaj molding tshuab
Peb- xim txhaj tshuaj molding yog qhov nyuaj tshaj li ob- cov txheej txheem xim thiab feem ntau yuav tsum tau tshwj xeeb rotary pwm los yog ntau- cov txheej txheem swb.
Nyob rau hauv cov nqe lus ntawm cov qauv pwm, kev sib xyaw ntawm ob qhov txav pwm cores thiab ob lub pwm nyob ruaj ruaj yog feem ntau siv, nrog rau lub phaj tig los hloov ntawm cov xim sib txawv. Qhov no qhia tau hais tias tus qauv tsim pwm siv ntau- xim txhaj tshuaj molding txheej txheem, siv lub phaj tig hloov ntawm cov xim sib txawv los yog cov ntaub ntawv kom tau raws li qhov xav tau ntawm ntau- xim lossis cov khoom siv sib xyaw ua ke.
Hais txog kev txhaj tshuaj, nws feem ntau ua raws li qhov kev txiav txim ntawm cov yas tawv → mos yas → overmolding, los yog pob tshab → xim → overmolding, kom ntseeg tau tias cov khoom siv tau zoo. Qhov no qhia tau hais tias nyob rau hauv multi-xim lossis ntau- cov ntaub ntawv txhaj tshuaj molding, qhov kev txhaj tshuaj ntawm cov khoom muaj feem cuam tshuam rau kev ua tau zoo thiab qhov zoo ntawm cov khoom kawg.
Hais txog cov khoom siv sib xws, feem ntau yog siv los ua ke cov khoom sib txawv, xws li ABS + LSR (cov roj hmab mos), lossis PC + TPU. Qhov no qhia tau hais tias cov pwm thiab cov txheej txheem tsim nyog rau kev txhaj tshuaj molding ntawm ntau yam ntaub ntawv, ua kom muaj kev sib xyaw thiab fusion ntawm cov khoom sib txawv.
III.Application Case Studies
Hauv xyoo dhau los, peb tau ua tiav ntau qhov kev txhaj tshuaj thib ob rautsheb teeb. Ntau- xim txhaj tshuaj molding yog qhov ua tau zoo dua li ib zaug - xim molding nrog ntau cov pwm, ua rau 85% nce hauv kev tsim khoom.
IV.Cov lus nug nquag thiab kev sib tw
1. Vim li cas ho tsis tsuas yog siv tshuaj tsuag pleev xim lossis luam ntawv kom ua tiav ntau yam -xim xim?
Teb: Txawm hais tias cov tshuaj tsuag pleev xim thiab luam ntawv tsis tshua muaj nqi, lawv feem ntau tsuas yog hloov xim ntawm cov khoom thiab muaj kev hnav tsis zoo thiab ua haujlwm ntev. Ob -xim / peb- xim txhaj tshuaj molding yog volumetric, lub ntsiab lus ntawm cov xim los yog cov khoom permeates tag nrho sab hauv ntawm cov yas, muab cov hnav tsis kam thiab ua haujlwm ntev, thiab ua kom muaj kev sib xyaw ntawm cov yas tawv thiab mos kom ua tau raws li qhov yuav tsum tau ua.
2. Dab tsi yog qhov nyuaj ntawm peb - xim txhaj tshuaj molding?
Teb:Cov teeb meem tseem ceeb yog nyob rau hauv qhov nyuaj ntawm pwm tsim thiab cov kev cai nruj rau cov txheej txheem tsis.
Pwm nqi: Peb- xim pwm feem ntau yog 1.5-2 npaug ntau dua li cov pwm xim ib zaug, thiab muaj lub voj voog tsim ntev dua.
Txhaj tshuaj molding tshuab synchronization: Qhov kub, siab, thiab ceev ntawm peb qhov kev txhaj tshuaj yuav tsum tau ua kom raug synchronized los tiv thaiv delamination.
* Kev xaiv cov khoom siv: Cov khoom sib txawv ntawm cov xim sib txawv yuav xav tau kev ua haujlwm sib txawv, thiab peb - xim txhaj tshuaj molding feem ntau txwv los ntawm qhov kub thiab txias.
