He aha te pepa parahi hikohiko (ED) me pēhea te hanga?

Pepa parahi hikohiko, he pepa whakarewa hanganga poutū, e kiia ana i te nuinga o te wā he mea hanga mā ngā tikanga matū, ko tōna tukanga whakaputa penei: 

Te whakarewatanga:Ka whakanohoia te rauemi mata o te pepa parahi hiko ki roto i te otinga waikawa whanariki hei whakaputa i te otinga parahi whanariki.

Te Hanga:Ka whakakahangia te porotaka whakarewa (te nuinga he porotaka titanium) ka tukuna ki roto i te wairewa parahi whanariki kia huri ai, ka mimiti te porotaka whakarewa kua utaina i ngā katote parahi i roto i te wairewa parahi whanariki ki te mata o te rakau porotaka, ā, ka puta he pepa parahi. Ko te matotoru o te pepa parahi e pā ana ki te tere hurihanga o te porotaka whakarewa, ko te tere o te hurihanga, ko te angiangi ake o te pepa parahi i hangaia; i tetahi atu taha, ko te puhoi ake, ko te matotoru ake. He maeneene te mata o te pepa parahi i hangaia i tēnei ara, engari e ai ki te pepa parahi he rerekē ngā mata o roto, o waho hoki (ka honoa tetahi taha ki ngā roera whakarewa), he rerekē te taratara o ngā taha e rua.

Te whakataratara(whiringa kore): 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 ki te kiri). 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 tapahite tapahi rānei:Ka tapatapahia, ka tapahia rānei te koiri pepa parahi kia rite ki te whānui e hiahiatia ana i roto i ngā rōra, i ngā rau rānei, e ai ki ngā hiahia o 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.
