Ngā Āhuatanga o te Hua
(1) Rauemi me te Kaha
Rino Kounga Teitei: He mea hanga ki te rino koranu kounga teitei pērā i te 42CrMoA, kia tino kaha ai te pūtu, kia pakari ai hoki hei tu atu i te pānga kaha me te wiri o ngā keri me ngā puru i raro i ngā āhuatanga mahi uaua.
Ngā Reanga Kaha Teitei: Ko ngā reanga kaha noa ko te 8.8, 10.9, me te 12.9. Ko te kaha kume o ngā pūtu reanga 10.9 he 1000-1250MPa te kaha kume me te kaha hua o te 900MPa, e tutuki ai ngā whakaritenga tono o te nuinga o ngā mīhini hanga; ko ngā pūtu reanga 12.9 he kaha ake, me te kaha kume o te 1200-1400MPa me te kaha hua o te 1100MPa, e tika ana mō ngā wāhanga motuhake he tino teitei ngā whakaritenga kaha.
(2) Hoahoa me te Hanganga
Hoahoa Upoko: Ko te hoahoa upoko hexagonal te tikanga, e whakarato ana i te taipana whakakī nui hei whakarite kia mau tonu te whakakī o te pūtu i te wā e whakamahia ana, ā, kia kore ai e ngāwari te wetewete. I taua wā anō, he watea hoki te hoahoa upoko hexagonal mō te tāutanga me te wetewete me ngā taputapu paerewa pēnei i ngā kī.
Hoahoa Miro: Ko ngā miro tino tika, e whakamahia ana ngā miro taratara, he pai te mahi raka-ā-koe. Ka tukatukahia te mata o te miro kia mau ai te pono me te tika o ngā miro, kia pai ake ai te kaha hononga me te pono o te pūtu.
Hoahoa Tiaki: He taupoki tiaki kei te pane o ētahi pūtu. He mata piko te pito o runga o te taupoki tiaki, ka taea te whakaiti i te waku i waenga i te pūtu me te whenua i te wā e whakamahia ana, ka whakaiti i te ātete, ka whakapai ake hoki i te whai huatanga o ngā keri me ngā puruta.
(3) Te Maimoatanga o te Mata
Maimoatanga Whakarewa: Hei whakapai ake i te ātete ki te waikura o te pūtu, he mea whakarewa te nuinga. Ka taea e te paparanga whakarewa te ārai i te waikura me te waikura o te pūtu i roto i ngā taiao makuku me te waikura, ka roa ake te ora o te pūtu.
Maimoatanga Phosphating: Ka whakaphosphatehia hoki ētahi pūtu. Ka taea e te paparanga phosphate te whakanui ake i te pakeke me te ātete ki te kakahu o te mata o te pūtu, me te whakapai ake hoki i te ātete ki te waikura o te pūtu.
