Furidzira Kuumbwa kupatsanura

Hollow kupora kuumbwa yakakamurwa kuita jekiseni blow molding, extrusion blow molding uye kutambanudza kuvhuvhuta kuumbwa, jekiseni kuvhuvhuta kuumbwa kwepurasitiki pasi billet nejekiseni rekugadzira nzira, uye ipapo iyo billet mukati mekuvhuvhuta mold yekuvhuvhuta. Mukuita kweextrusion blow molding, iyo chubhu billet inoburitswa zvakananga neiyo extruder uye yakaturikwa mugomba rakapatsanurwa rakaiswa pazasi pemusoro wemuchina. Apo iyo drooping billet inosvika pakureba kwakatarwa, kufa kunovharwa pakarepo, uye tube billet inogurwa nekucheka kwekufa. Kubva pakakamura mold pamusoro pegomba kupinda mumhepo yakamanikidzwa, billet ichivhuvhuta pedyo nemadziro eforoma uye kuumba; Chengetedza kumanikidza, uye tora zvigadzirwa mushure mekutonhodza uye kupedzisa mugomba rekuumbwa.  
 
Kune akawanda marudzi e thermoplastic anoshandiswa kugadzira hollow blow molding. Izvo zvinowanzo shandiswa mbishi zvinhu ndeye polyethylene, polypropylene, polyvinyl chloride uye thermoplastic polyester, nezvimwewo, izvo zvinowanzo shandiswa kugadzira akasiyana siyana emvura ekurongedza midziyo, senge akasiyana mabhodhoro, mbiya, magaba uye zvichingodaro. Kusiyanisa pakati pekufuridza extrusion uye jekiseni molding kuvhuvhuta (kusanganisira jekiseni kudhonza kuvhuvhuta) nzira ndeyekutarisa pasi pechigadzirwa, pazasi pane guvhu senge jekiseni rekuumba poindi yekuumba jekiseni kuvhuvhuta kana jekiseni kudhonza kuvhuvhuta zvigadzirwa, kuzasi kune mold line iri. iyo extrusion inofuridza zvigadzirwa.
