Raws li cov khoom siv los ntawm cov yas, nws yog cov txheej txheem nyuaj thiab lub nra hnyav ua rau lawv mus rau hauv cov khoom yas uas muaj qee yam zoo thiab siv tus nqi.Nyob rau hauv kev lag luam ntawm cov khoom yas, cov txheej txheem ntawm cov khoom siv yas yog tsim los ntawm plaub ntu txuas ntxiv: kev tsim cov yas, kev siv tshuab, kho kom zoo nkauj thiab sib dhos.
Hauv plaub txheej txheem no, yas molding yog tus yuam sij rau kev ua cov yas.Moulding txoj kev ntau li 30 hom, feem ntau yog ntau hom yas (hmoov, particle, tov los yog dispersion) rau hauv cov khoom uas xav tau los yog billet.Txoj kev molding feem ntau yog nyob ntawm hom yas (thermoplastic lossis thermosetting), thawj daim ntawv, thiab cov duab thiab qhov loj ntawm cov khoom.Yas ua cov thermoplastics feem ntau siv txoj kev yog extrusion, txhaj tshuaj molding, calendering, tshuab moulding thiab kub molding, yas ua thermosetting yas feem ntau siv molding, hloov molding, tab sis kuj txhaj molding.Laminating, molding, thiab thermoforming yog tsim cov yas rau ntawm qhov chaw tiaj tus.Cov txheej txheem ua cov yas saum toj no tuaj yeem siv rau kev ua cov roj hmab.Tsis tas li ntawd, muaj cov kua monomer los yog polymer li raw khoom casting, thiab lwm yam. Ntawm cov txheej txheem no, extrusion thiab txhaj tshuaj molding yog feem ntau siv thiab cov txheej txheem molding feem ntau.
Kev ua haujlwm ntawm cov khoom siv yas yog qiv cov txheej txheem ua cov yas ntawm cov hlau thiab ntoo, thiab lwm yam, los tsim cov khoom yas uas muaj qhov loj me lossis me me, thiab tseem tuaj yeem siv los ua cov txheej txheem molding, xws li cov saw. txiav ntawm extruded profiles.Vim qhov sib txawv ntawm cov yas thiab hlau thiab ntoo, cov yas thermal conductivity tsis zoo, coefficient ntawm thermal expansion, tsis tshua muaj modulus ntawm elasticity, thaum lub fixture los yog cov cuab yeej siab loj heev, yooj yim rau deformation, txiav kub yooj yim rau yaj, thiab yooj yim ua raws li lub cuab yeej.Yog li ntawd, cov yas machining, cov cuab yeej siv thiab cov kev txiav ceev yuav tsum hloov mus rau cov yam ntxwv ntawm cov yas.Feem ntau siv machining txoj kev yog pom, txiav, xuas nrig ntaus, tig, npaj, drilling, sib tsoo, polishing, xov ua thiab lwm yam.Tsis tas li ntawd, cov yas tuaj yeem raug txiav, drilled thiab welded nrog lasers.
Kev koom tes hauv kev tsim cov khoom yas Cov txheej txheem ntawm kev sib koom ua ke ntawm cov khoom yas yog vuam thiab kev sib txuas.Vuam txoj kev yog siv cov cua kub welding electrode vuam, siv kub yaj vuam, raws li zoo raws li high-frequency vuam, txhuam vuam, induction vuam, ultrasonic vuam thiab thiaj li nyob.Txoj kev sib khi tuaj yeem muab faib ua flux, resin tov thiab kub yaj nplaum raws li cov nplaum siv.
Lub hom phiaj ntawm kev hloov kho saum npoo ntawm cov khoom siv yas yog ua kom zoo nkauj ntawm cov khoom yas, feem ntau suav nrog: kev hloov kho tshuab, uas yog, cov ntaub ntawv, sib tsoo, polishing thiab lwm yam txheej txheem, tshem tawm cov burr, burr, thiab kho qhov loj me;Kev ua tiav, suav nrog txheej txheej ntawm cov khoom siv nrog cov xim, siv cov kuab tshuaj ua kom lub ntsej muag ci dua, siv cov qauv txheej txheej txheej ntawm cov khoom, thiab lwm yam;Kev siv cov xim, nrog rau cov xim pleev xim, luam ntawv thiab kub stamping;Kub plating, nrog rau lub tshuab nqus tsev, electroplating thiab chemical silver plating, thiab lwm yam. Cov txheej txheem yas kub stamping yog hloov cov xim txhuas ntawv ci txheej (los yog lwm cov qauv zaj duab xis) ntawm cov yeeb yaj kiab kub stamping rau lub workpiece nyob rau hauv cua sov thiab siab.Ntau yam khoom siv hauv tsev thiab cov khoom siv hauv tsev, cov khoom siv niaj hnub, thiab lwm yam, yog siv cov qauv no kom tau txais cov xim hlau lossis cov qauv ntoo.
Kev sib dhos yog kev ua haujlwm ntawm kev sib sau cov khoom yas rau hauv cov khoom tiav los ntawm gluing, welding thiab mechanical kev twb kev txuas.Piv txwv li, cov yas profiles tau sib sau ua ke rau hauv cov yas qhov rais thav ntawv thiab qhov rooj los ntawm sawing, vuam, drilling thiab lwm yam.
