Ose ari maviri maitiro aya anoshandiswa kugadzira maburi, asina musono zvikamu kubva kune thermoplastic polymers.Rotational molding inogonawo kushandiswa kune thermosets.Zvikamu zvinosiyana muhukuru kubva kumabhodhoro madiki epurasitiki e5 ml chete (0.15 oz) kusvika kumadhiramu makuru ekuchengetedza e38,000 l (10,000 gal) kugona.Kunyangwe iwo maviri maitiro achikwikwidza mune zvimwe zviitiko, kazhinji ivo vakawana yavo niches.Blow molding inonyanya kuenderana nekugadzirwa kwakawanda kwemidziyo midiki inoraswa, ukuwo kutenderera kuumbwa kuchifarira mahombe maumbirwo.
Blow molding inzira yekuumba umo kudzvanywa kwemhepo kunoshandiswa kupinza purasitiki yakapfava mugomba.Iyo yakakosha maindasitiri maitiro ekugadzira imwe-chidimbu maburi mapurasitiki ane madziro matete, semabhodhoro nemidziyo yakafanana.Sezvo zvizhinji zvezvinhu izvi zvichishandiswa pazvinwiwa zvevatengi zvemisika mizhinji, kugadzirwa kunowanzo kurongerwa huwandu hwakanyanya.Iyo tekinoroji inokweretwa kubva kuindasitiri yegirazi iyo mapurasitiki anokwikwidzana nawo mumusika unoraswa kana kudzokororwa wemabhodhoro.
Extrusion Blow Molding.Iyi fomu yekuvhuvhuta inoumbwa nekutenderera kunoratidzwa pazasi.Muzviitiko zvakawanda, maitiro akarongwa seyakanyanya kugadzirwa kwekugadzira mabhodhoro epurasitiki.Iyo inoteedzana inongozviitira uye inowanzo sanganiswa neyekudzika mashandiro akadai sekuzadza mabhodhoro uye kunyora.Kazhinji chinodikanwa kuti chigadziko chinoputika chive chakasimba, uye kusimba kunoenderana nekukora kwemadziro pakati pezvimwe zvinhu.
Jekiseni Blow Molding.Mukuita uku, parison yekutanga inoumbwa jekiseni kwete kuwedzeredzwa.Kutevedzana kwakapfava kunotsanangurwa pazasi.Kuenzaniswa neayo extrusion-based competitor, iyo jekiseni inoputika-inoumba maitiro ine yakaderera chiyero chekugadzira, iyo inotsanangura chikonzero nei isinganyanyi kushandiswa.
Mukusiyana kwekuumba jekiseni kuvhuvhuta, kunodaidzwa kuti stretch blow molding, tsvimbo inofuridza inokwira ichidzika pasi mujekiseni yakaumbwa parison panguva yenhanho 2, nekudaro kutambanudza purasitiki yakapfava uye kugadzira kushushikana kwakanyanya kwepolymer pane kwakajairika jekiseni kuvhuvhuta kana extrusion blow molding. .Chimiro chinokonzeresa chakanyanya kuomarara, nepamusoro pekujeka uye zvirinani kukanganisa kuramba.Iyo inonyanya kushandiswa zvinhu zve stretch blow molding is polyethylene terephthalate (PET), polyester ine yakaderera permeability uye inosimbiswa nekutambanudza-blow-molding process.Iko kusanganiswa kwezvivakwa kunoita kuti ive yakanaka semudziyo wezvinwiwa zvecarbonated.
Zvishandiso uye Zvigadzirwa.Blow molding inogumira kune thermoplastics.Polyethylene ndiyo polymer inonyanya kushandiswa kuvhuvhuta;kunyanya, high density uye high molecular weight polyethylene (HDPE neHMWPE).Mukuenzanisa zvivakwa zvavo neaya epasi density PE yakapihwa chinodiwa chekuomarara muchigadzirwa chekupedzisira, zvine hupfumi kushandisa izvi zvinodhura zvinhu nekuti madziro emidziyo anogona kuitwa matete.Kumwe kuvhuvhuta kunogadzirwa ne polypropylene (PP), polyvinylchloride (PVC), uye polyethylene terephthalate.
Midziyo inoraswa yekurongedza zvinhu zvemutengi zvemvura inoumba chikamu chikuru chezvigadzirwa zvinogadzirwa ne blow molding;asi handizvo chete zvigadzirwa.Zvimwe zvinhu zvinosanganisira madhiramu mahombe ekutakura (55 galoni) ezvinwiwa nehupfu, matangi makuru ekuchengetera (2000 galoni), matangi emotokari epeturu, matoyi, uye mapuranga emaseiri nemabhoti madiki.Muchiitiko chekupedzisira, mapuranga maviri ezvikepe anogadzirwa mune imwe chete kuumbwa uye anozochekwa kuita maviri akazaruka mabhuru.
