Dab tsi yog Kev faib tawm ntawm Cov Pwm Yas?
Dec 27, 2023| Kev faib tawm
A. Txhaj tshuaj molding - TV casing, keyboard nyees khawm, hluav taws xob khoom sab nrauv, computer peripheral yas khoom, khoom ua si, khoom siv hauv tsev (feem ntau siv)
B. Tshuab pwm-dej lub raj mis
C. Compression molding pwm - Bakelite keyboards, scientific porcelain tais diav
D. Hloov moulding pwm - cov khoom siv hluav taws xob sib xyaw
E. Extrusion pwm - kua nplaum raj, hnab yas
F. Thermoforming Pwm - Pob tshab tsim ntim plhaub
G. Rotational pwm - mos yas menyuam roj hmab cov khoom ua si
Raws li qhov sib txawv ntawm cov txheej txheem pouring, pwm tuaj yeem muab faib ua peb pawg:
(1) Loj nozzle pwm: Cov neeg khiav dej num thiab cov rooj vag yog nyob rau ntawm txoj kab sib faib thiab raug demoulded ua ke nrog cov khoom thaum qhib pwm. Nws muaj cov qauv tsim yooj yim tshaj plaws, ua haujlwm yooj yim, thiab muaj tus nqi qis. Yog li ntawd, ntau tus neeg siv lub tshuab nozzle loj los ua haujlwm.
(2) Slim nozzle pwm: Tus khiav thiab lub rooj vag tsis nyob rau ntawm txoj kab sib faib, feem ntau ncaj qha rau ntawm cov khoom, yog li nws yog ib qho tsim nyog los tsim ib qho ntxiv ntawm nozzle parting kab. Tus tsim yog complex thiab kev ua yog nyuaj. Feem ntau, kev xaiv yog nyob ntawm cov khoom xav tau. Fine nozzle system.
(3) Kub khiav pwm: Cov qauv ntawm cov pwm no yog roughly tib yam li cov nozzle zoo. Qhov sib txawv loj tshaj plaws yog tias tus neeg khiav dej num nyob rau hauv ib lossis ntau lub phaj kub khiav thiab cov cua kub kub nrog qhov kub thiab txias. Tsis muaj cov khoom txias demoulding, khiav thiab pouring. Qhov chaw nres nkoj yog ncaj qha rau ntawm cov khoom, yog li tus khiav tsis tas yuav tsum tau demoulded. Qhov system no tseem hu ua qhov tsis muaj chaw nres nkoj, uas tuaj yeem txuag cov khoom siv raw. Nws yog qhov tsim nyog rau cov xwm txheej uas cov khoom siv raw khoom kim heev, cov khoom yuav tsum muaj siab, tsim thiab kev ua haujlwm nyuaj, thiab cov nqi pwm yog siab.
Kub runner system, tseem hu ua kub khiav system, feem ntau muaj lub tes tsho kub khiav, kub khiav phaj, thiab kub tswj hluav taws xob lub thawv. Peb cov kev sib tw kub kub muaj ob hom: ib qho taw tes kub rooj vag thiab ntau qhov rooj kub kub. Ib qho taw tes kub lub rooj vag siv ib lub tes tsho kub sprue ncaj qha txhaj cov yas molten rau hauv pwm kab noj hniav. Nws yog tsim rau yas pwm nrog ib kab noj hniav thiab ib lub rooj vag; multi-point kub rooj vag ceg cov khoom molten mus rau ntau qhov chaw los ntawm ib tug kub khiav phaj. Cov cua sov muab faib rau hauv lub tes tsho sprue thiab ces nkag mus rau hauv pwm kab noj hniav. Nws yog haum rau ib leeg-kab noj mov multi-point noj los yog ntau kab noj hniav pwm.
