1. Karāhe whakamaroke
Ko te karāhe whakamaroke he momo karāhe kua whakamātauhia. Hei whakapai ake i te kaha o te karāhe, ka whakamahia ngā tikanga matū, ā-tinana rānei hei hanga i te ahotea pēhi ki runga i te mata o te karāhe. Ina pāngia te karāhe e ngā kaha o waho, ka whakakorea tuatahitia te ahotea o te mata, ka whakapai ake i te kaha kawe me te whakanui ake i te ātete ki te pēhanga hau, te ātete ki te huarere me te ātete pānga o te karāhe tonu.
2. Karāhe ārai
I hangaia te karāhe ārai i te tau 1865 e ngā Amerikana. Hei hiri i ngā taha karāhe e rua, neke atu rānei, kia kotahi ai, hei hanga hau maroke pumau i waenganui i ngā karāhe, ā, he mahi korehau anō hoki. Ka whakamahia he piripiri hiato kaha-teitei, ā, he nui te ātete-hau hei hono i te pepa karāhe ki te anga konumohe kei roto te mea whakamaroke. Ko te nuinga o ēnei he mea hanga e ngā wheketere nunui. Kāore he paru, he wai, he hauhautanga rānei i waenganui, he pai te mahi ārai wera me te haruru.
3. Karāhe whakakikoruatia
Ko te karāhe whakakikorua he mea hanga mai i ngā karāhe mānu e rua, neke atu rānei, kua pania ki te kiriata piri PVB (polyvinylbutyraldehyde), ka pēhia mā te pēhi wera, ka tukuna kia nui rawa atu, kātahi ka maka ki roto i te autoclave hei whakarewa i te iti o te hau toenga ki roto i te kiriata piri i raro i te pāmahana me te pēhanga teitei. Ināianei, he momo oumu hou tēnei, ka taea te tukatuka i te kiriata EVA motuhake o waho, ā, ka oti te tukanga whakapiri mā te papu korehau pāmahana teitei i roto i te oumu. Ka taea e te tangata te whiriwhiri i tētahi huarahi e tika ana kia rite ki tā rātou ake tahua, ki ngā whakaritenga o te wāhi me te putanga. Ki te whakatauritea ki ētahi atu karāhe, he ātete ki te ru, ki te tahae, ki te ātete matā me te ātete pahū te karāhe whakakikorua. I muri i te pakaru o te karāhe whakakikorua, he onge te marara nā te piri o te piri, ā, he tino teitei te haumaru.
Kāore i te teitei te kaha o te karāhe whakakikorua noa, he rite tonu ki te karāhe kotahi-wāhanga noa. He kaha, he haumaru hoki te karāhe whakakikorua i hangaia mai i te karāhe whakamaroke. He mea whakamahi noa i roto i ngā ārai o roto, i ngā papa taiapa, i ngā papa atamira me ngā pakitara ārai whānui.
I tēnei wā, e tino manakohia ana te oumu whakakikorua a Fangding nā te iti o te tapuwae, te iti o te haumitanga, te kounga teitei me te nui o te hua.
