Pōkaitiapepa parahi, he pepa whakarewa hanganga porowhita, ka hangaia, ka whakaputaina hoki mā te tikanga hurihuri ā-tinana, ko tōna tukanga whakaputa penei:
Te whakauru:Ka utaina te rauemi mata ki roto i te oumu rewa hei whakarewa ki roto i tētahi poro pou tapawhā. Mā tēnei tukanga ka whakatau te rauemi o te hua whakamutunga. Mō ngā hua koranu parahi, ka hanumihia ētahi atu konganuku i tua atu i te parahi i roto i tēnei tukanga.
↓
Taratara(Wera)Te hurihuri:Ka whakamahanahia te ingot ka hurihia hei hua takawaenga kua kopikopiko.
↓
Te Whakapūkara Waikawa:I muri i te hurihanga taratara ka horoia te hua takawaenga ki te otinga waikawa ngoikore hei tango i te paparanga waikura me ngā poke i runga i te mata o te rauemi.
↓
Te tika(Mātao)Te hurihuri:Ka hurihia anō te hua takawaenga rīpene kua horoia kia tae rā anō ki te matotoru e hiahiatia ana. I te mea he parahi te rauemi i roto i te tukanga hurihuri, ka pakeke haere tōna ake rauemi, ka uaua te hurihuri i te rauemi tino pakeke, nō reira, ina tae te rauemi ki tētahi pakeketanga, ka whakamahanahia kia whakaitihia te pakeketanga o te rauemi, kia māmā ake ai te hurihuri. I taua wā anō, kia kore ai e puta ngā rōra i roto i te tukanga hurihuri ki runga i te mata o te rauemi nā te whakairo hohonu rawa, ka whakanohoia he mira kounga teitei ki waenganui i te rauemi me ngā rōra i roto i te kiriata hinu, ko te kaupapa kia teitei ake te mata o te hua whakamutunga.
↓
Te tango hinu:Ko tēnei mahi e wātea ana i roto i ngā hua papai anake, ko te kaupapa he horoi i te hinu miihini i uru mai ki roto i te rauemi i te wā e hurihuri ana. I roto i te tukanga horoi, ka mahia te maimoatanga ātete waikura i te pāmahana rūma (e kiia ana ko te maimoatanga passivation), arā, ka tukuna he kaihoko passivation ki roto i te wai horoi hei whakaroa i te waikura me te tae ke o te pepa parahi i te pāmahana rūma.
↓
Te whakamahana:Ko te whakatioatatanga ā-roto o te rauemi parahi mā te whakamahana i te pāmahana teitei, ā, ka whakaitihia tōna mārō.
↓
Te whakataratara(Whiringa): Ka whakakorikoria te mata o te pepa parahi (ka rehuhia te paura parahi, te paura cobalt-nickel rānei ki te mata o te pepa parahi, kātahi ka whakamaroke) hei whakanui ake i te pakari o te pepa parahi (hei whakapakari i tōna kaha kiri). I roto i tēnei tukanga, ka rongoatia hoki te mata kanapa ki te maimoatanga waikura pāmahana-tiketike (kua whakakikoruatia ki te paparanga konganuku) hei whakanui ake i te kaha o te rauemi ki te mahi i ngā pāmahana teitei me te kore e waikura, e memeha rānei te tae.
(Kia mōhio: Ko te tikanga ka mahia tēnei tukanga ina hiahiatia aua rauemi anake)
↓
Te tapahi:ka wehea te rauemi konumohe parahi hurihuri ki te whānui e hiahiatia ana kia rite ki ngā whakaritenga a te kiritaki.
↓
Te whakamātautau:Tapahia ētahi tauira mai i te rōra kua oti hei whakamātautau i te hanganga, te kaha kume, te roa, te manawanui, te kaha kiri, te taratara, te whakaotinga me ngā hiahia o te kiritaki hei whakarite he tika te hua.
↓
Te tākai:Tākaihia ngā hua kua oti te whakarite kia tutuki i ngā ture i roto i ngā puranga ki roto i ngā pouaka.
