Plastiki kuputira
- Hollow blow molding, kukurumidza kugadzirwa kwepurasitiki. Munguva yeHondo Yenyika Yechipiri, kuumbwa kwekurova kwakatanga kushandiswa kugadzira yakaderera density polyethylene flask. Mukupera kwema50s, nekuzvarwa kwepamusoro density polyethylene uye kugadzirwa kwemhepo yekuumba muchina, kuvhuvhuta tekinoroji yakashandiswa zvakanyanya.Kuwanda kwechigadziko chegomba kunogona kusvika zviuru zvemalita, uye zvimwe zvekugadzira zvakadzorwa nekombuta. .
- Mapurasitiki ekuputira kuumbwa ndeye polyethylene, polyvinyl chloride, polypropylene, polyester uye zvichingodaro. Iwo makomba midziyo anoshandiswa zvakanyanya semaindasitiri ekurongedza midziyo. Iyo blowing molding inogona kukamurwa kuita extrusion blow molding uye jekiseni blow molding, uye ichangobva kugadzirwa yakawanda layer blow molding uye tensile blow molding ichangogadzirwa.
