Ko nga kaiwhakarato waahanga parahi parahi ritenga na te whakangao haumi mai i Haina meTe miihini CNC, maimoatanga mata me nga ratonga maimoatanga wera.
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 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.
Ko nga tikanga tirotiro e waatea ana: te whakamatautau inenga na te CMM, te whakamatautau kore-whakangaro, te hanganga matū, nga taonga miihini, te whakamatautau pakeke, te whakataurite pateko, te whakataurite hihiri, te pehanga hau me te pehanga wai.
E ai ki nga rauemi here rereke e whakamahia ana mo te hanga i te anga, ka taea te wehea te makanga haumi ki te whakarewa silica sol me te maka karaihe wai. He pai ake te Whakaaetanga Makanga Ahu (DCT) me nga Whakaaetanga Whakamaahanga Geometrical (GCT) i te mahinga karaihe wai. Heoi, ahakoa na roto i te mahinga whakarewanga kotahi, ka rereke te Tohu Whakaaetanga mai i ia koranu whakarewa na runga i o raatau rerekee. Kei te pirangi to maatau miihini ki te korero ki a koe mena he tono motuhake koe mo nga mea e hiahiatia ana. I konei e whai ake nei ko nga karaehe whakamaaramatanga whanui ka taea e taatau ma te whakarewanga o te silica sol me nga mahi whakarewa karaihe wai motuhake:
- ✔ Koeke DCT na Silica Sol Ngaro Wax Maka: DCTG4 ~ DCTG6
- ✔ Koeke DCT ma te Kaata Wai Ngaro Waahi Maka: DCTG5 ~ DCTG9
- ✔ Koeke GCT na Silica Sol Ngaro Wax Maka: GCTG3 ~ GCTG5
- ✔ Koeke GCT ma te Karaehe Wai Ngaro Wax Maka: GCTG3 ~ GCTG5
