Pane misiyano kune iyo extrusion process zvinoenderana nerudzi rwe extrusion iri kuitwa.Heano kutarisa kune akasiyana marudzi e extrusion, uye misiyano kubva kune yakakosha maitiro kune yega yega.
Sheet Extrusion
Sheet extrusion, inozivikanwawo semufirimu extrusion, inoshandiswa kugadzira mapepa epurasitiki nemafirimu, uye inowanzosiyana kubva kune yekutanga extrusion maitiro maererano nekutonhora maitiro.Pane kushandisa kugeza nemvura kutonhodza chigadzirwa chakapedzwa, mapepa anotonhodzwa nekudhonzwa kuburikidza nematatu kusvika mana pinch rollers.Mukuwedzera kune kutonhora kwechigadzirwa, ma rollers anoshandiswawo kuona kuwanda kwechigadzirwa chekupedzisira.
Yakaputika Firimu Extrusion
Blown film extrusion inoshandiswa kugadzira zvigadzirwa zvakaita semabhegi ekutenga epurasitiki.Maitiro acho akafanana neyekutanga extrusion process kusvika padanho resin inopinda mufa.Divi icylinder yakatwasuka ine denderedzwa.Iyo resin yakanyungudutswa inodhonzwa kumusoro kubva kufa nepeya yenip rolls yakakwira pamusoro pedhiya.Kuchinja kumhanya kweaya nip rollers kuchachinja ukobvu hwefirimu repurasitiki.Kutenderedza kufa kunogara mhepo inoyerera yakavakirwa kutonhora mhete, iyo inotonhorera chigadzirwa apo inofamba ichikwira.Mhepo inopeperetswa mufa, ichiwedzera iyo extruded chigadzirwa.Iyi firimu inogona kubva yaiswa spooled kana kudhindwa, kucheka kuita maumbirwo, kana kupisa-yakavharwa mune zvimwe zvigadzirwa.
Tubing Extrusion
Tubing extrusion inoshandiswa kugadzira zvigadzirwa zvakaita semashanga kana tubing yekurapa.Maitiro acho akafanana neyekutanga maitiro kusvika resin yasvika kufa.Pini (mandrel) inoiswa mukati mekufa.Iyo yakanyungudutswa resin inosundirwa mufa, ichigadzira yakatenderedza mandrel.Aya ndiwo magadzirirwo ehollow shape ye tubing.Air pressure inoshandiswa kuyera ukobvu hwetubhing.
Aya angori mashoma emaitiro anoshandiswa epurasitiki extrusion.Kubatsira kukuru kune ese aya mafomu epurasitiki extrusion process ndeyekuti ivo vanopa huwandu hwakasiyana hwekuita geometric pane mamwe mafomu ekugadzira epurasitiki fomu.Misiyano yezvimiro uye saizi inogona kugadzirwa yakakura, ine ganhuriro chete iri yekuti chigadzirwa chinofanirwa kunge chine chimiro chinoenderera.
