Muaj kev hloov pauv rau cov txheej txheem extrusion nyob ntawm seb hom extrusion yog dab tsi.Ntawm no yog saib ntawm ntau hom extrusion, thiab qhov sib txawv ntawm cov txheej txheem yooj yim rau txhua tus.
Ntawv Extrusion
Sheet extrusion, tseem hu ua zaj duab xis extrusion, yog siv los ua cov ntawv yas thiab cov yeeb yaj kiab, thiab feem ntau nws txawv ntawm cov txheej txheem extrusion txheej txheem hais txog cov txheej txheem txias.Tsis yog siv cov dej da dej kom txias cov khoom tiav, cov nplooj ntawv tau txias los ntawm kev rub los ntawm ib qho ntawm peb mus rau plaub pinch rollers.Ntxiv rau qhov txias ntawm cov khoom, cov chais kuj tseem siv los txiav txim siab qhov tuab ntawm cov khoom kawg.
Blown Zaj duab xis Extrusion
Blown film extrusion yog siv los ua cov khoom xws li hnab yas khw.Cov txheej txheem yog tib yam li cov txheej txheem extrusion yooj yim mus txog rau qhov taw tes ntawm cov resin mus rau hauv qhov tuag.Cov tuag yog ib lub tog raj kheej upright nrog ib ncig qhib.Lub melted resin yog rub upwards los ntawm qhov tuag los ntawm ib khub ntawm nip yob siab tshaj qhov tuag.Hloov qhov ceev ntawm cov nip rollers yuav hloov lub thickness ntawm cov yas zaj duab xis.Nyob ib ncig ntawm qhov tuag zaum ib lub nplhaib cua txias raws li cua txias, uas ua rau cov khoom txias thaum nws nce mus.Cua yog cua tshuab rau hauv qhov tuag, nthuav cov khoom extruded.Cov yeeb yaj kiab no tuaj yeem raug spooled los yog luam tawm, txiav rau hauv cov duab, lossis kub-sealed rau hauv lwm yam khoom.
Tubing Extrusion
Tubing extrusion yog siv los ua cov khoom xws li straws lossis tubing kho mob.Cov txheej txheem yog tib yam li cov txheej txheem pib mus txog rau thaum cov resin ncav cuag qhov tuag.Ib tus pin (mandrel) muab tso rau hauv qhov tuag.Lub melted resin yog ces thawb mus rau hauv tuag, tsim nyob ib ncig ntawm lub mandrel.Qhov no yog li cas lub hollow puab ntawm lub raj yog tsim.Cua siab yog siv los ntsuas lub thickness ntawm lub raj.
Cov no tsuas yog qee qhov ntawm cov txheej txheem siv rau yas extrusion.Qhov zoo tshaj plaws rau tag nrho cov ntaub ntawv no ntawm cov txheej txheem yas extrusion yog tias lawv muab ntau yam geometric possibilities dua lwm cov ntaub ntawv ntawm cov ntaub ntawv yas.Qhov sib txawv ntawm cov duab thiab qhov ntau thiab tsawg uas tuaj yeem tsim tau yog qhov loj, nrog rau qhov kev txwv tsuas yog tias cov khoom yuav tsum muaj qhov txuas txuas ntxiv.
