Maitiro ekusuma

3/4 yezvibodzwa zvakaumbwa zvinogadzirwa ne extrusion blow molding.Iyo extrusion maitiro ndeyekumanikidza zvinhu kuburikidza negomba kana kufa kugadzira chigadzirwa.

The extrusion blow molding process ine matanho mashanu: 1. Plastic preform (extrusion of hollow plastic chubhu).2. Vhara iyo flap mold pane parison, sunga mold uye ucheke parini.3. Pfuura mold kumadziro anotonhora emukati, gadzirisa kuvhura uye chengetedza imwe dzvinyiriro panguva yekutonhora.4. Vhura mold uye bvisa zvikamu zvinoputika.5. Cheka flash kuti uwane chigadzirwa chapera.

Extrusion hollow blow molding process
Extrusion hollow blow molding ndeyekunyungudutsa uye kuisa plastiki mupurasitiki mune extruder, uyezve extrude tubular parison kuburikidza tubular die.Kana iyo parison inosvika pahurefu hwakati, iyo parison inopisa mukati mekurova mold.Mhepo yakadzvinyirirwa inozopeperetswa mukati kuti iite kuti parison iri padyo nemadziro egomba rekuumbwa kuti iwane chimiro chegomba, uye pasi pemamiriro ekuchengetedza imwe dzvinyiriro, mushure mekutonhora uye kuumbwa, chigadzirwa chinoputika chinowanikwa nekudhirowa.Nzira ye extrusion blow molding ndeyotevera.
Purasitiki → plastiki uye extrusion → tubular parison → mold kuvhara → inflation kuumba → kutonhora → kuvhura mold → bvisa chigadzirwa
Extrusion blow molding inogona kupatsanurwa kuita nhanho shanu dzinotevera, sezvakaratidzwa muFigure 1-1.
① Iyo polymer inonyungudutswa kuburikidza neextruder, uye iyo yakanyunguduka inoumbwa kuita tubular parison kuburikidza nekufa.
②Apo jeri rinosvika pakureba kwakafanotemerwa, kuvhuvhuta mold yakavharwa, jeri rinosungirirwa pakati pemahafu maviri ekuumbwa, uye jeri rinochekwa roendeswa kune chimwe chiteshi.
③Baya mweya wakadzvanyirirwa mupuriso kuti uwedzere parison kuti iite pedyo negomba rekuumba.
④ Nyarara pasi.
⑤ Vhura mold uye tora chigadzirwa chakaumbwa.
