Puas yog extrusion molding zoo dua li kev txhaj tshuaj molding?

Cia peb nkag siab txog cov txheej txheem ntawm extrusion molding. Extrusion molding yog txheej txheem ntawm extruding yas los yog roj hmab rau hauv cov khoom siv ntev ntev los ntawm cov pwm qhov nrog cov duab hla ntu. Cov txheej txheem no zoo ib yam li cov kev paub ntawm cov tshuaj txhuam hniav raug nyem tawm ntawm lub raj - tsis tu ncua thiab sib xws. Kev txhaj tshuaj molding, ntawm qhov tod tes, koom nrog kev txhaj tshuaj molten yas rau hauv cov kab noj hniav kaw, ua kom txias thiab ua kom ruaj khov los tsim cov khoom. Cov txheej txheem no zoo li cov dej khov nab kuab tau muab tso rau hauv daim phiaj dej khov, tos kom txias thiab khov.
Ib qho txiaj ntsig tseem ceeb ntawm extrusion molding yog nws lub peev xwm los tsim cov khoom ntawm qhov ntev ntev. Qhov no yog vim hais tias cov txheej txheem extrusion yog tas mus li, tsuav yog cov khoom siv tsis tu ncua, nws tuaj yeem tsim tsis kawg. Hauv qhov sib piv, kev txhaj tshuaj molding tsis tu ncua thiab tsuas tuaj yeem tsim tau ib lossis ob peb yam khoom ntawm ib lub sijhawm, ib yam li daim phiaj dej khov tuaj yeem ua tau raws li qhov txwv ntawm cov dej khov nab kuab ib zaug. Yog li ntawd, extrusion molding muaj qhov zoo sib xws hauv kev tsim cov khoom loj xws li cov kav dej thiab cable sheaths.
Qhov thib ob, qhov tseeb qhov tseeb thiab qhov chaw du ntawm cov khoom extruded feem ntau yog siab. Vim yog qhov nruam thiab tsis sib xws ntawm cov ntaub ntawv, qhov sib txawv ntawm qhov ntev ntawm cov khoom extruded tuaj yeem khaws cia zoo ib yam. Kev txhaj tshuaj molded cov khoom yuav muaj qhov hloov pauv loj thiab qhov tsis xws luag vim yog yam xws li pwm hnav thiab tsis sib xws ntawm cov yas molten. Qhov no zoo li qhov sib txawv ntawm cov tswm ciab xuas tes ua thiab lub tshuab ua cov tswm ciab - yav dhau los yuav muaj qhov tsis zoo me ntsis, thaum lub sijhawm tom kawg muaj qhov zoo sib xws.
Nyob rau hauv cov nqe lus ntawm kev siv cov khoom, extrusion molding kuj qhia tau zoo. Vim lub fact tias cov ntaub ntawv poob thaum lub sij hawm extrusion txheej txheem feem ntau yog los ntawm kev txiav thiab tom qab ua, thiab thaum lub sij hawm txhaj tshuaj molding txheej txheem, cov khoom seem xws li rooj vag thiab risers yuav raug generated, uas feem ntau ua pov tseg. Yog li ntawd, cov khoom siv ntawm extrusion molding yog siab dua, uas tsis tsuas yog txo cov nqi tab sis kuj txo qhov cuam tshuam rau ib puag ncig.
Tsis tas li ntawd, qhov ntau lawm ceev ntawm extrusion molding tuaj yeem ceev heev. Tshwj xeeb tshaj yog rau qee cov khoom me me, xws li cov hnab ntim cov hnab yas lossis cov pas nrig, cov extrusion ceev tuaj yeem tshaj qhov kev txhaj tshuaj molding. Qhov no ua rau extrusion molding muaj txiaj ntsig thiab kev lag luam hauv kev tsim cov khoom zoo li no.
Txawm li cas los xij, qhov no tsis tau txhais hais tias extrusion molding yog qhov zoo tshaj rau kev txhaj tshuaj molding hauv txhua yam. Txhaj tshuaj molding muaj qhov zoo tshaj plaws hauv kev tsim cov khoom nrog cov duab nyuaj, qhov loj me, thiab cov kev xav tau siab. Piv txwv li, kev tsim cov khoom siv hluav taws xob nyuaj, cov khoom siv hauv tsheb, thiab lwm yam. feem ntau xav tau cov txheej txheem txhaj tshuaj molding kom ua tiav.
Thaum kawg, cia peb piv cov txheej txheem no los ntawm kev ua piv txwv. Piv txwv tias peb yuav tsum tsim ib pawg ntawm cov laj kab yas. Yog siv extrusion molding, peb tuaj yeem ua kom sov PVC cov khoom rau hauv lub xeev yas thiab ncaj qha extrude lawv los ntawm extruder thiab pwm los tsim ib lub laj kab ntev. Cov strips ntev no tuaj yeem txiav rau hauv txhua qhov ntev raws li qhov xav tau, thiab tag nrho cov txheej txheem txuas ntxiv thiab ua haujlwm tau zoo. Yog tias siv kev txhaj tshuaj molding, peb yuav tsum tsim cov pwm cais rau txhua qhov laj kab, tom qab ntawd txhaj cov yas molten rau hauv pwm, tos kom txias, thiab ua kom tau cov khoom tiav. Txoj kev no muaj kev ua haujlwm qis dua hauv kev tsim cov khoom lag luam ntau tus qauv, thiab tus nqi ntawm cov pwm kuj yog siab dua.
Extrusion molding tau qhia txog qhov zoo ntawm kev tsim cov khoom loj, txhim kho kev siv cov khoom siv, thiab ua kom cov khoom ua tau zoo. Txawm li cas los xij, qhov no tsis tau txhais hais tias extrusion molding tuaj yeem hloov pauv kev txhaj tshuaj molding. Cov txheej txheem ob leeg muaj lawv tus kheej zoo thiab tsim nyog rau kev tsim khoom sib txawv thiab cov yam ntxwv ntawm cov khoom. Thaum xaiv cov cuab yeej ua haujlwm tsim nyog, cov neeg tsim khoom yuav tsum ua tib zoo xav txog ntau yam xws li cov khoom tsim, cov yam ntxwv ntawm cov khoom, cov nqi txwv, thiab kev cuam tshuam ib puag ncig.
