Niaj hnub no Kev Tshawb Fawb Kev Tshaj Tawm: Yas Pwm

Plastic pwm yog dab tsi?
Yas pwm yog cov pwm ua ke siv rau compression molding, extrusion molding, txhaj tshuaj molding, tshuab moulding, thiab tsis tshua muaj npuas molding. Kev sib koom ua ke ntawm kev hloov pauv ntawm cov pwm thiab concave pwm ntawm cov pwm thiab cov txheej txheem ua haujlwm tuaj yeem ua cov txheej txheem ntawm cov yas nrog cov duab sib txawv thiab ntau thiab tsawg. Yas pwm yog leej niam ntawm kev lag luam, thiab kev tso tawm ntawm cov khoom siv yas. Nws feem ntau suav nrog cov pwm concave nrog cov kab noj hniav sib txawv uas tsim los ntawm concave pwm ua ke substrate, concave pwm tivthaiv, thiab concave pwm ua ke clamp phaj, thiab concave pwm nrog ib tug sib txawv cores ntawm convex pwm ua ke substrate, convex pwm. tivthaiv, convex pwm ua ke clamp phaj, kab noj hniav txiav tivthaiv, thiab ib sab txiav ua ke phaj.
Cov txheej txheem tsim cov yas pwm
1. Thaum lub sij hawm txhaj tshuaj molding, cov pwm yog clamped mus rau lub tshuab txhaj tshuaj molding, thiab cov yas molten yog txhaj rau hauv pwm kab noj hniav, qhov uas nws txias thiab zoo li tus.
2. Sib cais cov pwm sab saud thiab qis, thiab siv cov txheej txheem ejection kom tshem tawm cov khoom ntawm cov pwm kab noj hniav thiab tawm hauv pwm.
3. Cov pwm raug kaw dua rau kev txhaj tshuaj molding tom ntej, thiab tag nrho cov txheej txheem txhaj tshuaj yog cyclic.
Yam cuam tshuam rau kev tsim cov pwm yas
1. Sib faib nto
Thaum cov pwm raug kaw, cov pwm concave thiab convex yog tsim los ntawm kev sib koom ua ke.
2. Cov yam ntxwv ntawm cov khoom
Lawv yog slider, inclined saum, ncaj saum thaiv, thiab lwm yam rau complex pwm.
3. Pwm raug
Nrog rau kev zam ntawm daim npav, qhov tseeb qhov chaw, cov ncej qhia, qhov chaw pins, thiab lwm yam.
4. Pouring system
Nyob nruab nrab ntawm kev txhaj tshuaj molding tshuab nozzle thiab pwm kab noj hniav, nws yog tsim los ntawm lub ntsiab ntws channel, splitter channel, lub rooj vag, thiab cov khoom txias.
5. Cov khoom lag luam zoo
Qhov zoo ntawm qhov chaw, Hardness, elongation thiab lwm yam khoom ntawm cov khoom ua tiav.
6. Pwm ua haujlwm raws li txoj cai
Thaum cov pwm rov ua haujlwm dua, nws yuav tsum tau ua cov txheej txheem ntau zaus xws li pwm kaw, xauv, txhaj tshuaj molding, kev tswj siab, txias, pwm qhib, thiab ejection. Cov txheej txheem no yuav tsum ua kom ntseeg tau tias kev ua haujlwm hloov pauv ntawm txhua lub tshuab. Lubrication yuav tsum tau thiab kev saib xyuas yuav tsum tau ua kom nws nyob rau hauv kev pom kev ua haujlwm zoo.
Cov teeb meem tshwm sim nrog cov pwm yas
1. Kev tawg
Kev tawg yog ib qho tsis xws luag hauv cov khoom yas, feem ntau tshwm sim los ntawm kev ntxhov siab deformation. Muaj cov kev ntxhov siab tseem ceeb, kev ntxhov siab sab nraud, thiab kev ntxhov siab deformation tshwm sim los ntawm ib puag ncig sab nraud.
2. Tsis txaus filling
3. Pitted nto
Yog vim li cas rau qhov tsis xws luag yog qhov tseem ceeb tib yam li tsis txaus sau
4. Lub qhov dej shrinkage
5. Tshaj ntug
6. Weld marks
Lub cim fusion yog tshwm sim los ntawm qhov txias ntawm lub hauv ntej kawg ntawm cov molten resin los ntawm ntau cov lus qhia thiab tsis tiav fusion ntawm qhov sib txuas
ntawm
7. Kub
Kev kub nyhiab tshwm sim los ntawm ntau yam xws li kev siv tshuab, pwm, lossis pwm pwm
8. Nyiaj hlau
Cov hlau nyiaj yog feem ntau tshwm sim los ntawm kev nqus dej noo ntawm cov khoom
9. Dav hlau qauv
Dav hlau streaks yog cov kab uas khoov zoo li nab raws li kev khiav ntawm lub rooj vag. Nws yog tshwm sim los ntawm kev txhaj tshuaj siab ntawm resin pib los ntawm lub rooj vag.
10. Warping thiab deformation
11. Dawb
Ua los ntawm kev demolding tsis zoo
12. Npuas
Kev ceev faj rau xaiv cov pwm yas
1. Tsis txhob tsom ntsoov rau cov khoom tsim thiab tsis saib xyuas cov yas pwm tsim.
2. Tsis txhob saib tus nqi xwb, xav txog qhov zoo, lub voj voog, thiab kev pabcuam los ntawm txhua yam.
3. Tsis txhob muaj kev sib koom tes ntau thiab siv zog ua ke nrog cov yas pwm tsim thiab ua cov khoom lag luam kom ntau li ntau tau.
