Puas yog extrusion txheej txheem casting?

1, Cov txheej txheem txheej txheem thiab cov yam ntxwv
Casting: Casting yog ib txoj kev tsim uas yuav tsum tau nchuav cov hlau los yog hlau rau hauv cov pwm npaj ua ntej, tso cai rau nws kom txias thiab khov kom tau txais cov duab xav tau thiab qhov loj ntawm qhov chaw lossis qhov khoob. Cov txheej txheem casting feem ntau suav nrog cov kauj ruam xws li melting, pouring, txias thiab solidification, thiab demolding, nrog rau cov tub ntxhais ntawm kev siv cov fluidity ntawm hlau los sau cov pwm qhov chaw.
Squeezing: Squeezing yog siv lub zog siab los quab yuam cov khoom siv raw xws li hlau, yas, ceramics, thiab lwm yam los ntawm lub qhov lossis qhov khoob ntawm cov pwm, ua rau cov yas deformation thiab tau txais cov khoom zoo thiab qhov loj ntawm cov khoom. Cov txheej txheem extrusion feem ntau suav nrog cov theem xws li kev npaj cov khoom siv raw, cua sov (rau cov hlau), extrusion deformation, thiab tom qab ua tiav (xws li cua txias, txiav, straightening, thiab lwm yam). Tus yuam sij rau extrusion yog nyob rau hauv kev siv cov yas deformation muaj peev xwm ntawm cov khoom kom ua tiav cov kev hloov pauv raws li qhov txwv ntawm pwm.
2, Khoom siv tau thiab cov yam ntxwv ntawm cov khoom
Casting: Cov txheej txheem casting yog tsim rau ntau yam khoom siv hlau xws li hlau, hlau, txhuas, tooj liab, nrog rau qee yam khoom tsis yog xim hlau xws li xuab zeb hauv xuab zeb casting. Casting cov khoom feem ntau muaj qhov loj me, los ntawm qhov me me ntawm ob peb millimeters mus rau cov khoom loj ntawm ob peb meters, uas tuaj yeem tsim tau. Txawm li cas los xij, qhov zoo thiab cov qauv sab hauv ntawm cov khoom cam khwb cia feem ntau ua tsis zoo rau cov khoom forged thiab machined, nrog rau qhov tsis xws luag xws li porosity thiab shrinkage.
Extrusion: Extrusion tshuab yog dav siv nyob rau hauv kev ua ntawm ntau yam ntaub ntawv xws li hlau, plastics, ceramics, thiab lwm yam. Squeezed khoom muaj zoo xws li high precision, siab nto zoo, zoo mechanical zog, thiab seem stability. Tshwj xeeb tshaj yog hlau extrusion khoom, xws li txhuas alloy profiles, tooj liab kav, thiab lwm yam., muaj ntau yam kev siv nyob rau hauv aerospace, automotive manufacturing, tsev kho kom zoo nkauj thiab lwm yam teb.
3, Qhov sib txawv thiab zoo sib xws ntawm Extrusion thiab Casting
Los ntawm kev xav ntawm cov txheej txheem txheej txheem, ob qho tib si extrusion thiab casting koom nrog cov khoom deformation thiab siv cov pwm, tab sis muaj qhov sib txawv tseem ceeb hauv lawv cov qauv deformation thiab kev tsav tsheb. Casting cia siab rau qhov fluidity ntawm cov ntaub ntawv los sau qhov chaw pwm, thaum extrusion siv cov yas deformation muaj peev xwm ntawm cov ntaub ntawv kom ua tiav cov kev hloov pauv raws li qhov txwv ntawm pwm. Tsis tas li ntawd, thaum lub sij hawm extrusion txheej txheem, cov khoom yog feem ntau nyob rau hauv ib tug ntau dua kub thiab siab lub xeev, uas yuav pab txhim kho nws cov plasticity thiab flowability, ua rau nws yooj yim mus cuag complex zoo forming.
4, Puas yog extrusion belongs rau cov txheej txheem casting
Raws li kev soj ntsuam saum toj no, peb tuaj yeem xaus tias extrusion tsis koom nrog cov txheej txheem casting. Txawm hais tias ob qho tib si muaj kev siv dav hauv kev ua cov khoom siv, muaj qhov sib txawv tseem ceeb hauv lawv cov txheej txheem txheej txheem, cov yam ntxwv, cov khoom siv, thiab cov khoom nta. Casting feem ntau yog nyob ntawm qhov dej ntawm cov ntaub ntawv los sau cov pwm qhov chaw, thaum extrusion ua tiav cov duab hloov los ntawm cov yas deformation ntawm cov ntaub ntawv. Yog li ntawd, cais extrusion raws li txheej txheem casting yog tsis raug.
