Ib, Qhov tseem ceeb ntawm Pwm raug nyob rau hauv Consumer Electronic Plastic Parts
Cov khoom yas rau cov neeg siv khoom siv hluav taws xob feem ntau yog me me, nyias-walled, thiab cov txheej txheem nyuaj, thiab yog li ntawd muaj qhov nruj me me thiab kev ua siab ntev. Yog tias pwm tsis raug txaus, nws tuaj yeem ua rau muaj teeb meem hauv qab no:
Nyuaj hauv kev sib dhos: Yog tias cov khoom yas tsis haum ua ke kom zoo, lawv yuav tsis raug teeb tsa kom raug.
Cov kev txwv ua haujlwm: khawm, keyboards, lossis kev sib tshuam uas tsis ua haujlwm zoo tuaj yeem ua rau nws nyuaj rau kev siv cov khoom ib txwm.
Cov tsos mob tsis zoo: Warping, shrinking, los yog indentations yuav hloov li cas cov khoom zoo li.
Tus nqi siab dua: Tsawg- cov khoom yas yas yuav tsum tau muab txiav los yog ua tiav dua.
2, Kev cuam tshuam ntawm cov khoom siv pwm thiab kev ua haujlwm raug
Cov khoom siv los ua pwm muaj qhov cuam tshuam ncaj qha rau qhov raug thiab qhov zoo ntawm cov khoom yas. Qee yam khoom siv yog:
Hlau (P20, H13): muaj lub siab tawv, tiv taus hnav, tsis nthuav ntau thaum cua sov, thiab muaj txiaj ntsig zoo rau kev ua ntau yam khoom.
Aluminium yog ib qho yooj yim rau kev ua hauj lwm nrog thiab zoo rau kev ua prototypes los yog batch me me, tab sis nws hnav sai sai, uas ua rau nws tsis tshua muaj tseeb rau lub sij hawm ntev - manufacturing.
Qhov tseeb ntawm kev ua pwm kuj tseem ceeb heev. CNC machining nrog siab precision, EDM paug machining, thiab sib tsoo tuaj yeem pab ua kom cov kab noj hniav qhov ntev tib yam. Qhov roughness ntawm pwm qhov chaw cuam tshuam li cas cov khoom yas 'ntws zoo li cas thiab zoo npaum li cas lawv haum ua ke. Yog hais tias thermal expansion tsis tswj kom zoo, cov khoom yas yuav shrink los yog distort unevenly.
3, Yuav ua li cas tus qauv tsim pwm cuam tshuam qhov raug
Kev tsim cov qauv pwm muaj feem cuam tshuam rau qhov tseeb ntawm cov khoom yas hauv cov hauv qab no:
Parting nto tsim: Yog hais tias qhov parting nto tsis nyob rau hauv qhov chaw, nws yuav yooj yim distort los yog flash npoo. Nyias-cov phab ntsa yog qhov rhiab heev thiab yuav tsum sib npaug ntawm qhov lawv saib thiab yooj yim npaum li cas lawv tshem tawm ntawm pwm.
Gate design: Tus naj npawb, qhov loj, thiab qhov chaw ntawm lub rooj vag txhua tus txiav txim siab seb cov yas ntws zoo li cas. Kev tsim tsis zoo tuaj yeem ua rau shrinkage, contraction, lossis npuas.
Exhaust system: Qhov chaw thiab tus naj npawb ntawm cov pa tawm qhov cuam tshuam zoo li cas cov cua ntws tawm. Yog tias qhov tso pa tawm tsis zoo, nws tuaj yeem ua rau lub qhov cua lossis qhov ua txhaum.
Tsim cov cua txias: Tus nqi ntawm shrinkage thiab tus nqi ntawm warping nyob ntawm seb qhov sib npaug ntawm qhov ua kom txias. Yog tias qhov txias txias tsis yog, qhov ntev tuaj yeem hloov pauv.
Ib qho zoo- qauv pwm tsim yuav ua kom paub tseeb tias qhov loj thiab zoo ntawm cov khoom yas nyob twj ywm tib lub sijhawm.
4, Kev sib koom tes ntawm kev txhaj tshuaj molding txheej txheem thiab pwm tsim
Nws tsuas yog ib qho tseem ceeb rau kev ua pwm thiab kev sib dhos kom raug. Yog hais tias lub machining tsis raug txaus, cov khoom yas tuaj yeem muaj qhov tsis raug. Yog tias qhov kev sib dhos ua tsis tau zoo, cov npoo flash, warping, lossis cov qauv tsis sib xws tuaj yeem tshwm sim. Ua kom cov khoom ruaj khov rau lub sijhawm ntev
Siv high -paj machining technologies kom paub tseeb tias cov kab noj hniav qhov ntev yog lawm.
Xyuas kom tseeb tias qhov sib txawv ntawm cov pwm yog me me heev kom qhov chaw sib cais yog du.
Txheeb xyuas cov pwm rau hnav thiab tsim kua muag tsis tu ncua, thiab kho thiab tswj lawv raws li xav tau.
Tag nrho qhov zoo ntawm cov yas yog nyob ntawm seb cov pwm raug tsim thiab muab tso ua ke.
5, Yuav ua li cas tus tsim pwm thiab cov txheej txheem txhaj tshuaj molding ua hauj lwm ua ke
Txawm hais tias cov pwm ua tau zoo- ua, qhov tseeb ntawm cov khoom yas tseem tuaj yeem cuam tshuam los ntawm kev tswj tsis zoo ntawm cov txheej txheem txhaj tshuaj molding. Cov txheej txheem tseem ceeb tshaj plaws yog:
Kev nrawm thiab siab ntawm kev txhaj tshuaj: Yog tias lub siab qis dhau lawm, lub filling yuav tsis ua tiav thiab cov khoom yuav ntsws.
Tuav lub sijhawm: Yog tias lub sijhawm tuav tau luv dhau lossis ntev dhau lawm, nws tuaj yeem ua rau qhov txawv txav los yog muaj kev ntxhov siab ntau dhau.
Tswj lub sijhawm txias thiab qhov kub thiab txias: Yog tias qhov txias txias tsis yog, cov khoom tuaj yeem ntswj lossis ntsws tsis sib xws.
Txhawm rau kom paub tseeb tias cov khoom yas yog qhov loj thiab zoo, cov pwm tsim yuav tsum ua haujlwm zoo nrog cov txheej txheem txhaj tshuaj molding.
6, Feem ntau cov teeb meem raug
Qee qhov teeb meem tshwm sim nrog qhov tseeb thaum ua cov khoom yas raucov khoom siv hluav taws xob yog:
Warping deformation tshwm sim thaum qhov chaw txias tsis sib xws, cov phab ntsa tuab heev, lossis qhov sib cais ntawm qhov tsis zoo.
Shrinkage thiab shrinkage: Cov no yuav tsum ua nrog kev tsim ntawm lub rooj vag, kev tswj lub siab npaum li cas, lossis qhov nrawm ntawm cov yas shrinks.
Dimensional sib txawv: tsis txaus txaus nyob rau hauv pwm ua los yog tsis muaj peev xwm tswj thermal expansion zoo.
Flow marks, npuas, thiab dents ntawm qhov chaw hloov li cas cov khoom zoo li thiab li cas tib neeg siv lawv.
