He maha ngā āhuatanga pai o te paura karāpiti, nō reira he whānuitia te whakamahinga i roto i te mahi whakarewa, te mīhini, te hiko, te matū, te kakahu, te tiaki whenua me ētahi atu rāngai ahumahi. He wāhanga taupatupatu, he rerekētanga hoki ngā mara tono o te paura karāpiti tūturu me te paura karāpiti horihori. Kei te ētita karāpiti Furuite e whai ake nei ngā mara tono o te paura karāpiti me te paura karāpiti horihori.
1. Ahumahi whakarewa
I roto i te umanga whakarewa, ka taea te whakamahi i te paura karāpeti tūturu hei hanga rauemi ātete-waikura pērā i ngā pereki konupūmā-waro me ngā pereki konumohe-waro nā te mea he pai tōna ātete ki te waikura. Ka taea te whakamahi i te paura karāpeti horihori hei hiko hanga maitai, engari he uaua te whakamahi i ngā hiko i hangaia ki te paura karāpeti tūturu i roto i ngā oumu hiko hanga maitai me ngā āhuatanga mahi uaua.
2. Ahumahi mīhini
I roto i te umanga mīhini, ka whakamahia ngā rauemi karāpiti hei rauemi ātete-kakahu me te whakahinuhinu. Ko te rauemi mata tuatahi mō te whakarite i te karāpiti whakawhanui ko te karāpiti waro-teitei, ā, ko ētahi atu matū matū pēnei i te waikawa whanariki kukū (neke atu i te 98%), te hauwai waikura (neke atu i te 28%), te pāhare pākawa pāhare pākawa, me ētahi atu, he matū ahumahi katoa. Ko ngā mahi whānui o te whakarite koia ēnei: i te pāmahana e tika ana, ka tāpirihia ngā ōwehenga rerekē o te otinga hauwai waikura, te karāpiti maori me te waikawa whanariki kukū i roto i ngā tukanga rerekē, ka tauhohehia mō tētahi wā i raro i te whakaoho tonu, kātahi ka horoia ki te wai kia kore e tau, kātahi ka hurihia. I muri i te whakamaroke, ka whakamarokehia ki te korehau i te 60 °C. He pai te whakahinuhinu o te paura karāpiti maori, ā, he maha ngā wā ka whakamahia hei tāpiri mō ngā hinu whakahinuhinu. Ko ngā taputapu mō te kawe i te reo waikura e whakamahi whānuitia ana i ngā mowhiti piston, ngā mowhiti hiri me ngā peera i hangaia mai i te paura karāpiti horihori, ā, kāore e hiahiatia te tāpiri hinu whakahinuhinu i te wā e mahi ana. Ka taea hoki te whakamahi i te paura karāhe maori me ngā rauemi hiato kapia pūmua i ngā mara o runga ake nei, engari kāore te ātete ki te kakahu i te pai ki te paura karāhe horihori.
3. Ahumahi matū
Ko ngā āhuatanga o te paura karāti horihori ko te ātete ki te waikura, te kawe wera pai, me te iti o te uruhanga. He whānuitia te whakamahinga i roto i te umanga matū hei hanga i ngā whakawhiti wera, i ngā tāke tauhohenga, i ngā pourewa mimiti, i ngā tātari me ētahi atu taputapu. Ka taea hoki te whakamahi i te paura karāti maori me ngā rauemi hiato kapia polymer i roto i ngā mara o runga ake nei, engari kāore te kawe wera me te ātete ki te waikura i te pai ki ērā o te paura karāti horihori.
I te whanaketanga tonu o ngā hangarau rangahau, kāore e taea te ine i te tirohanga whānui mō te whakamahinga o te paura karāpeti horihori. I tēnei wā, ko te whanaketanga o ngā hua karāpeti horihori me te karāpeti tūturu hei rauemi mata tētahi o ngā huarahi nui ki te whakawhānui ake i te mara whakamahinga o te karāpeti tūturu. Kua whakamahia te paura karāpeti tūturu hei rauemi mata āwhina i roto i te hanga o ētahi paura karāpeti horihori, engari kāore i te rawaka te whanaketanga o ngā hua karāpeti horihori me te paura karāpeti tūturu hei rauemi mata matua. Koinei te huarahi pai ki te whakatutuki i tēnei whāinga mā te mārama me te whakamahi i te hanganga me ngā āhuatanga o te paura karāpeti tūturu, me te tango i ngā tukanga, ngā huarahi me ngā tikanga e tika ana hei whakaputa i ngā hua karāpeti horihori me te hanganga, ngā āhuatanga me ngā whakamahinga motuhake.
