I te mea ka taea te hanga i nga koranu parahi, te parahi me te parahi ki nga waahanga tino uaua, he pai mo tetukanga makanga haumi. Ko nga rereketanga o te utu ka nui ake te utu o enei rawa, ka nui te utu o te para, ina koa ka whakaaro koe ki te miihini CNC me/ranei te hangahanga hei mahi whakangao hei whakaputa i o waahanga whakarewa. Ko te parahi parakore i te nuinga o te waa kaore i te maka. Ko te whakangao (wax kua ngaro) he tikanga mo te whakarewanga tika o nga taipitopito ahua tata-kupenga ma te whakamahi i nga tauira ware pi. Ko te whakarewanga haumi, te ware pi ngaro ranei he tikanga hanga whakarewa e whakamahi ana i te tauira ware pi e karapotia ana e te anga uku hei hanga i te maaka uku. Ka maroke te anga, ka rewa te ware pi, ka waiho ko te maaka anake. Na ka hangaia te waahanga whakarewa ma te ringihanga i te whakarewa whakarewa ki roto i te maaka uku.
Ko te parahi he koranu he parahi me te konutea. Ko te parahi he parahi me te konutea ka kiia ko te parahi noa. Mēnā he momo koranu he nui ake i te rua ngā huānga, ka kīia he parahi motuhake. Ko te parahi he koranu parahi me te konutea te mea matua. I te piki ake o te ihirangi zinc, ka tino piki ake te kaha me te kirihou o te koranu, engari ka tino heke iho nga ahuatanga miihini i muri i te neke atu i te 47%, na te mea he iti iho i te 47% te ihirangi zinc o te parahi. I tua atu i te konutea, he maha nga wa kei roto i te parahi whakarewa nga mea whakauru penei i te silicon, konupora, konumohe, me te mata.
He teitei ake nga taonga miihini o te maka parahi i te parahi, engari he iti ake te utu i te parahi. He maha nga wa e whakamahia ana te parahi maka mo nga rakau kawe rakau, ngahere, nga taputapu me etahi atu waahanga me nga reera me etahi atu waahanga aukati-waikura. He kaha te whakakakahu o te parahi. He maha nga wa e whakamahia ana te parahi ki te hanga vaolo, paipa wai, paipa hono mo nga hau o roto me waho, me nga radiators.
