Cov laj thawj tseem ceeb ntawm cov kab weld yog: thaum cov yas molten ntsib cov ntxig ntxig, qhov, qhov chaw uas tsis muaj qhov nrawm nrawm lossis qhov chaw uas cuam tshuam cov dej ntws hauv cov pwm kab noj hniav, qhov sib txuam ntawm ntau yam melts;Thaum lub qhov rooj txhaj tshuaj molding tshwm sim, cov ntaub ntawv tsis tuaj yeem raug fused tag nrho.Piv txwv li, cov khoom siv hluav taws xob plhaub,mov nplej plhaubSandwich tshuab yas plhaub , yas khau khib ,tsheb OEM pem hauv ntej bumper, thiab lwm yam Tom ntej no, peb yuav qhia txog cov laj thawj tshwj xeeb thiab cov kev daws teeb meem ntawm cov kab weld.
1. Qhov kub thiab txias yog qis heev
Qhov qis-kub yaj muaj qhov tsis zoo shunting thiab confluence kev ua tau zoo thiab yog ib qho yooj yim rau kev weld kab.Hauv qhov no, qhov kub ntawm lub thoob thiab lub nozzle tuaj yeem tsim nyog nce lossis lub voj voog txhaj tshuaj tuaj yeem txuas ntxiv los txhawb qhov nce ntawm cov khoom kub.Nyob rau tib lub sijhawm, qhov dhau ntawm cov dej txias hauv pwm yuav tsum tau tswj thiab cov pwm kub yuav tsum tau nce kom tsim nyog.
2. Pwm tsis xws luag
Cov txheej txheem tsis zoo ntawm cov pwm pouring system muaj kev cuam tshuam zoo rau kev sib xyaw ntawm cov khoom siv molten, vim tias qhov tsis zoo fusion feem ntau tshwm sim los ntawm kev sib txawv thiab kev sib txuam ntawm cov khoom molten.Yog li ntawd, lub rooj vag daim ntawv uas muaj kev sib txawv tsawg yuav tsum tau txais kev pom zoo kom deb li deb tau thiab lub rooj vag txoj hauj lwm yuav tsum raug xaiv kom tsim nyog kom tsis txhob muaj qhov tsis sib xws ntawm pwm filling tus nqi thiab cuam tshuam cov pwm ntim cov khoom ntws.Yog tias ua tau, ib lub rooj vag taw tes yuav tsum raug xaiv, vim tias lub rooj vag no tsis tsim ntau cov kwj ntawm cov khoom, thiab cov khoom molten yuav tsis converge los ntawm ob qho kev qhia, uas yog ib qho yooj yim kom tsis txhob weld marks.
3. Pwm tsis zoo
Tom qab qhov kev ua txhaum no tshwm sim, ua ntej ntawm tag nrho cov, xyuas seb lub qhov tso tawm ntawm cov pwm yog thaiv los ntawm cov khoom ruaj khov ntawm cov khoom molten lossis lwm yam khoom, thiab seb puas muaj cov khoom txawv teb chaws ntawm lub rooj vag.Yog tias cov ntsiab lus carbonation tseem tshwm sim tom qab tshem tawm qhov thaiv, ib lub qhov tso pa yuav tsum tau ntxiv rau ntawm qhov chaw khaws khoom tuag.Nws tseem tuaj yeem ua kom nrawm dua los ntawm kev hloov kho lub rooj vag lossis tsim nyog txo qhov kaw quab yuam thiab ua kom qhov sib txawv ntawm qhov tso pa tawm.Nyob rau hauv cov nqe lus ntawm cov txheej txheem kev khiav hauj lwm, pab kev ntsuas xws li txo cov khoom kub thiab pwm kub, shortening high-pressure txhaj lub sij hawm thiab txo cov kev txhaj tshuaj siab kuj yuav coj.
4. Kev siv tsis raug ntawm kev tso tawm tus neeg sawv cev
Ntau dhau pwm tso tawm tus neeg sawv cev lossis ntau yam tsis raug yuav ua rau cov cim ntawm cov khoom yas.Hauv kev txhaj tshuaj molding, ib qho me me ntawm tus neeg sawv cev tso tawm feem ntau siv sib npaug nkaus xwb ntawm qhov chaw uas tsis yooj yim rau demould, xws li xov (txhaj tshuaj yas kev cai PA6 txiv ntoo).Nyob rau hauv txoj cai, tus nqi tso tawm tus neeg sawv cev yuav tsum raug txo kom tsawg.Kev xaiv ntawm ntau tus neeg tso tawm yuav tsum tau txiav txim siab raws li cov txheej txheem molding, cov duab ntawm cov khoom yas thiab ntau yam khoom siv raw.
5. Cov qauv yas tsis tsim nyog tsim
Yog tias cov phab ntsa tuab ntawm cov khoom yas yog tsim los nyias nyias, tej zaum yuav muaj qhov sib txawv ntawm cov thickness thiab ntau dhau, uas yuav ua rau tsis zoo fusion.Yog li ntawd, thaum tsim cov qauv qauv ntawm cov khoom yas, nws yuav tsum tau ua kom ntseeg tau tias qhov thinnest ntawm cov khoom yas yuav tsum ntau dua li qhov tsawg kawg nkaus phab ntsa thickness tso cai rau lub sij hawm molding.Tsis tas li ntawd, kev siv cov ntawv ntxig yuav tsum raug txo kom tsawg thiab cov phab ntsa thickness yuav tsum zoo ib yam li qhov ua tau.
