Ko ngā whakamahinga o te paura karāhe penei:
1. Hei ātete ahi: he āhuatanga ātete pāmahana teitei me te kaha teitei te karāpeti me ōna hua, i roto i te umanga whakarewa e whakamahia ana te nuinga hei hanga para karāpeti, i roto i te hanga maitai e whakamahia ana hei ārai mō te ingot maitai, te arai o te oumu whakarewa.
2. Hei rauemi kawe hiko: e whakamahia ana i roto i te umanga hiko hei hanga i ngā irahiko, ngā paraihe, ngā tokotoko waro, ngā ngongo waro, ngā gasket graphite, ngā wāhanga waea, te paninga ngongo pikitia pouaka whakaata, me ētahi atu.
3. Rauemi whakahinuhinu ātete ki te kakahu: he maha ngā wā ka whakamahia te karāpeti i roto i te umanga miihini hei whakahinuhinu.
Kāore e taea te whakamahi i te hinu whakahinuhinu i ngā āhuatanga tere teitei, pāmahana teitei me te pēhanga teitei, engari ka taea te whakamahi i ngā rauemi ātete-kakahu karāhe i te pāmahana (I) 200~2000℃ i te tere reti tino teitei, me te kore hinu whakahinuhinu. He maha ngā taputapu mō te kawe i ngā mea waikura he mea hanga ki te karāhe i roto i ngā kapu piston, ngā mowhiti hiri me ngā peera, e mahi ana me te kore hinu whakahinuhinu.
He hinu whakahinuhinu pai anō hoki te karāpiti mō ngā tukanga mahi whakarewa maha (te tuhi waea, te tuhi ngongo).
4. Te whakarewa, te whakarewa konumohe, te whakahāngai me ngā rauemi whakarewa pāmahana teitei: nā te iti o te tauwehenga whānui wera o te karāhe, me te kaha ki te whakarerekē i te ru wera, ka taea te whakamahi hei pokepoke karāhe, i muri i te whakamahi i te karāhe pango whakarewa he tino tika te rahi, he maeneene te mata, kāore e hiahiatia he tukatuka, he iti noa te tukatuka ka taea te whakamahi, ā, ka penapenahia he nui te konganuku.
5. Ka taea hoki e te paura karāpiti te ārai i te unahi o te kōhua, e whakaatu ana te whakamātautau wae e tika ana mā te tāpiri i tētahi nui o te paura karāpiti ki roto i te wai (tata ki te 4 ki te 5 karamu ia tana wai) ka ārai i te unahi o te mata kōhua.
Hei tāpiri, ka taea e te karāpeti kua pania ki ngā auahi whakarewa, ngā tuanui, ngā piriti, me ngā paipa te ārai i te waikura.
6. Ka taea te whakamahi i te paura graphite hei tae, hei whakakanapa.
Hei tāpiri, he mea hanga hoki te graphite hei karāhe māmā me te kaihoko oro pepa me te kaihoko ārai-waikura i roto i te umanga, ā, he mea hanga hoki mō ngā pene, te waituhi, te peita pango, te waituhi me te taimana horihori, he rauemi mata nui mō te taimana.
He rauemi tino pai tēnei mō te penapena pūngao me te tiaki taiao, kua whakamahia e te Hononga o Amerika hei pākahiko mō te motuka.
I te whanaketanga o te pūtaiao me te hangarau hou me te ahumahi, kei te whānui haere tonu te mara tono o te karāpeti. Kua noho hei rauemi mata nui mō ngā rauemi hiato hou i roto i te mara hangarau teitei, ā, he mea nui tana mahi i roto i te ōhanga o te motu.
