1. Blow mold mold design process yakasiyana, blow mold mold design is jekiseni + kuvhuvhuta;Jekiseni kuumba jekiseni + kumanikidzwa;Roll molding is extrusion + pressure;Kuvhuvhuta kunofanirwa kuve nemusoro wakasiiwa nepombi yekukweva, jekiseni rekugadzira rinofanirwa kunge riine chikamu chegedhi, inotenderedza purasitiki yekucheka inofanira kunge ine burr.

2. Kazhinji kutaura, jekiseni molding is solid core, blow molding uye roll molding haina chinhu musimboti.Majekiseni epasi pepamusoro anopenya, kuvhuvhuta uye roll epurasitiki pamusoro haina kuenzana.Blow molding and roll molding comparison at least blow molding ine muromo unofuridza.Uku kuenzanisa kwakawanda.Hameno kana muchigona kunzwisisa!!
3. Shrinkage yemapurasitiki uye ayo anofurira zvinhu
Thermoplastics ine midziyo yekuwedzera kana yapiswa, chibvumirano kana yatonhodzwa, uyezve ichidzikira kana ichidzvinyirirwa.Mukati mekugadzira jekiseni, ipurasitiki yakanyungudutswa inotanga kubaiwa mugomba rekuumbwa, mushure mekuzadza, kunyunguduka kunotonhodzwa uye kusimba, uye shrinkage inoitika kana zvikamu zvepurasitiki zvabviswa mu mold, iyo inonzi kuumba shrinkage.Zvikamu zvepurasitiki kubva pakuumbwa kusvika pakugadzikana kwenguva ino yenguva, pachava nekushanduka kuduku muhukuru, kuchinja kunoramba kuchiderera, shrinkage iyi inonzi post-shrinkage.Imwe mutsauko ndeyekuwedzera kwemamwe mapurasitiki ehygroscopic nekuda kwekutorwa kwemwando.Semuenzaniso, kana mvura yenylon 610 iine 3%, kuwedzera kwekukura kuri 2%;Kana iyo mvura yegirazi faibha yakasimbiswa naironi 66 iri 40%, saizi yekuwedzera i0.3%.Asi kuumba shrinkage kunobata basa guru.
