Cov txheej txheem kev txhaj tshuaj moulding yog ib txoj kev tsim khoom uas embeds hlau nplaum rau hauv cov ntaub ntawv yas. Nws yog tsuas yog siv los tsim cov khoom siv hlau nplaum nrog cov duab tshwj xeeb thiab kev ua haujlwm. Cov txheej txheem no sib xyaw ua ke ntawm kev ua haujlwm ntawm cov ntaub ntawv sib nqus nrog molding yooj yim ntawm cov yas, kom cov khoom muaj ob qho tib si sib nqus zog thiab complex geometric qauv thiab cov yam ntxwv tiv thaiv. Cov hauv qab no yog cov kauj ruam yooj yim, cov yam ntxwv thiab daim ntawv thov kev taw qhia ntawm cov hlau nplaum txhaj tshuaj molding txheej txheem.
General cov kauj ruam ntawm cov hlau nplaum txhaj molding txheej txheem:
1. Kev xaiv hlau nplaum
Raws li daim ntawv thov ntawm cov khoom kawg, xaiv hom hlau nplaum tsim nyog, xws li NdFeB, ferrite lossis lwm hom.
2. Magnet pretreatment
Cov hlau nplaum yuav tsum tau kho saum npoo ua ntej txhaj tshuaj molding, xws li ntxuav thiab polishing, txhawm rau txhim kho qhov adhesion ntawm cov hlau nplaum thiab cov yas.
3. Pwm tsim
Thaum tsim cov pwm txhaj tshuaj, nws yog ib qho tsim nyog yuav tsum tau tseg qhov kev tso kawm ntawm cov hlau nplaum kom ntseeg tau tias cov hlau nplaum tuaj yeem ruaj khov rau hauv cov yas.
4. Kev txhaj tshuaj molding khoom npaj
Xaiv cov khoom siv yas uas tsim nyog, xav txog nws qhov kev tiv thaiv tshav kub, lub zog txhua yam thiab seb puas yuav tsum muaj cov khoom tshwj xeeb (xws li kub tsis kam, nplaim hluav taws xob).
5. Txhaj tshuaj molding
Nyob rau hauv cov xwm txheej ntawm kev tswj qhov kub thiab txias, cov yas molten yog txhaj rau hauv pwm los puag ncig cov hlau nplaum ua ntej tso. Qhov kub thiab txias yuav tsum tau tswj nruj me ntsis thaum lub sij hawm txhaj tshuaj molding txheej txheem kom tsis txhob kub ntau dhau ua rau demagnetization ntawm cov hlau nplaum.
6. Txias thiab tshem tawm
Tom qab txhaj tshuaj tiav lawm, cia cov yas txias thiab khov rau ib lub sijhawm, thiab tom qab ntawd tshem tawm cov pwm los ntawm pwm.
7. Kev tshuaj xyuas thiab kev sim
Thaum kawg, ntau yam kev ntsuam xyuas xws li cov khoom sib nqus, qhov tseeb qhov tseeb, thiab cov tsos zoo yog ua los xyuas kom meej tias lawv ua tau raws li cov neeg siv khoom xav tau.
