Me mohio koe ki te karaihe papa-rua.Ko te hua kapu ake noa me te whakamahia pinepine i roto i to tatou oraraa.Kei te mohio koe ki te tikanga hanga o te karaehe papa-rua?I muri mai, kia mohio tatou ki te kaupapa o te hangarua o te karaehe pupuhi pupuhi:
1. Ko te karaehe paparua-rua ka pupuhihia e te ringa
Ko te pupuhi a-ringa he mahi uaua ake.Tuatahi, me toua tetahi pito o te ngongo parahi, ngongo rino ranei kia rewa ai te karaihe.Me pupuhi koe ki tera pito o te ngongo pupuhi kia pupuhi ki te ahua e hiahiatia ana e tatou, katahi ka whakamahi i te kutikuti hei whakaiti.Ki runga.I roto i te tukanga o te pupuhi a-ringa i te karaehe paparua-rua, ko te ringa o te kaiwhakahaere ko te huri tonu i te ngongo pupuhi kia kore ai e ngaro te otinga karaihe.I tetahi atu taha, ko te tikanga o te whakamahi i te pokey o te karaehe hei hanga ki te ahua e hiahiatia ana e tatou.Ma tenei ara, ka taea te whakakii i te karaehe paparua-rua e pupuhihia ana kia pai ai te mahi tahi me te mahi tahi.Me mohio ko te rahi me te matotoru o te karaehe paparua-rua ka whakatauhia e te nui o te hau e pupuhi ana.
2. Mouled blow molding
Tuatahi whakamahia te parahi, te rino ranei hei hanga tauira tuwhera, katahi ka whakamahi i te ngongo pupuhi hei toua i te rewa o te karaehe, hoatu te wairewa karaihe ki roto i te pokepokea ai ka timata ki te pupuhi kia kapi katoa te otinga karaihe ki te pakitara o roto o te tauira ka tango pokepokea ai.Ma tenei ara, ka taea te hanga i nga kapu karaehe paparanga-rua o nga momo ahua, e taapiri ana i te toi ki te ahua o te tinana kapu.
Inaianei ka whiriwhiria e te tangata he karaehe papa-rua, ehara i te mea he whakaritenga mo tana mahi engari mo tona ahua ano, na reira ka taea e tatou te whakatutuki i nga hiahia o te iwi ma te whiriwhiri i te tikanga pupuhi tika.
