Cast firimu imhando yeisina-yakatambanudzwa, isina-yakatarisana flat extrusion firimu inogadzirwa nekunyunguduka kukanda nekudzima.Pane nzira mbiri dze single layer salivation uye multi-layer co-extrusion salivation.Inofananidzwa nefirimu yakaputirwa, inoratidzirwa nekukurumidza kugadzira kukurumidza, kubuda kwepamusoro, kujeka kwefirimu, kupenya, kufanana kwakakora, etc. Panguva imwecheteyo, nokuti ifirimu ye-flat-extrusion, maitiro anotevera akadai sekudhinda uye lamination zvakanyanyonakira.Naizvozvo, inoshandiswa zvakanyanya mukurongedza machira, maruva, chikafu uye zvinodiwa zvezuva nezuva.
Kugadzirwa kweCPP kune nzira mbiri: single-layer casting uye multi-layer co-extrusion casting.Iyo imwe-layer firimu inonyanya kuda kuti zvinhu zvive zvakanaka zvakaderera-kupisa kupisa-sealing performance uye kuchinjika.Multi-layer co-extruded cast firimu inogona kupatsanurwa kuita zvidimbu zvitatu: kupisa seal layer, tsigiro layer, uye corona layer.Sarudzo yezvinyorwa yakafara kupfuura imwe layer film.Izvo zvinhu zvinosangana nezvinodiwa zvega rega rega zvinogona kusarudzwa mumwe nemumwe, zvichipa iyo firimu zvakasiyana Mabasa uye kushandiswa.Pakati pavo, chisimbiso chekupisa-chisimbiso chinoda kuvharwa-chisimbiso, kunyunguduka kwezvinhu zvakaderera, pfuma yakanyunguduka yakanaka, kupisa-kupisa kwekushisa kwakafara, uye kuvhara kuri nyore;chikamu chekutsigira chinotsigira firimu uye chinowedzera kuoma kwefirimu;corona Iyo dhizaini inoda kudhindwa kana kugadzirwa nesimbi, uye ine mwero pamusoro tension inodiwa.Kuwedzerwa kwezvinowedzera kunofanira kunge kuine zvishoma.
