Ka whakamahia e te maka kirikiri te kirikiri kaakaariki (te kirikiri makuku) te kirikiri maroke ranei hei hanga i nga punaha whakarewa. Ko temakanga kirikiri matomatoKo te tukanga whakarewa tawhito i whakamahia i roto i te hitori. A, no te hanga i te pokepokea ai, me whakaputa nga tauira i mahia mai i te rakau, i te whakarewa ranei hei hanga i te kohao tuwhera. Ka ringihia te konganuku whakarewa ki roto i te kohao hei hanga i nga whakarewatanga i muri i te whakamatao me te whakamaroketanga. He iti ake te utu o te whakarewa kirikiri i era atu tukanga whakarewa mo te whanaketanga maaka me te waahanga whakarewa. Ko te makanga kirikiri, ko te tikanga o te maka kirikiri kakariki (mehemea kaore he whakaahuatanga motuhake). Heoi ano, i enei ra, ko etahi atu o nga mahi whakarewa kei te whakamahi i te onepu hei hanga i te pokepokea ai. Kei a ratou ano o ratou ingoa, peneite whakarewa anga maata, kapia furan pani kirikiri makanga (kaore he momo tunu),ngaro pahuka i makame te maka korehau.
He rereke nga momo makanga mo to whiringa. Ko tetahi waahanga o te tukanga whiriwhiri mo to kaupapa ko te kowhiringa o te mahi makanga e pai ana ki o hiahia. Ko te ahua tino rongonui ko te whakarewa kirikiri me te hanga tauira o tetahi waahanga kua oti (tauira ranei) ka kopirihia ki te kirikiri me nga taapiri here hei hanga i te whakarewanga whakamutunga. Ka tangohia te tauira i muri i te hanga o te pokepokea ai te ahua ranei, a ka whakauruhia te whakarewa ma te punaha omaoma hei whakakii i te kohao. Ka wehea te kirikiri me te whakarewa, ka horoia te makanga ka oti mo te tuku ki te kaihoko.
Maka kirikiri VS Anga Mould Maka:
Ka whakamahia te kirikiri me te whakarewa anga mo te kirikiri hei hanga i te kohao tuwhera mo te ringihanga. Ko te rereketanga ko te whakamahi i te kirikiri kirikiri he onepu matomato, he kirikiri maroke ranei (ko te whakarewanga pahuka i ngaro me te whakarewanga korehau e whakamahi ana i te kirikiri maroke hei hanga pokepokea ai), i te wa e whakamahia ana e te whakarewanga anga te kirikiri whakakikoruatia kapia hei hanga i nga punaha hangai. Kaore e taea te whakamahi ano te kirikiri kua pania. Heoi, he pai ake te kounga o nga whakarewa anga i tera okirikiri kirikiri.
Maka kirikiri VS Makanga haumi:
He rereke enei mahinga whakarewanga e rua i roto i nga taonga hangai mo te hanga tauira.Makanga haumika whakamahi i te ware pi ki te whakaputa i nga tauira ware pi (na reira i kiia ai ko te whakarewa wax ngaro) he rite te rahi me te rahi ki nga whakarewanga e hiahiatia ana. Katahi ka whakakikoruatia nga tauira ware pi ki te onepu me nga taonga here (te nuinga o te silica sol he karaihe wai ranei) hei hanga anga kaha mo te ringihanga whakarewa whakarewa. I te nuinga o te waa, ka tangohia e te makanga kirikiri te kirikiri kaakaariki, te kirikiri maroke ranei hei hanga i te kohao tuwhera, he rite te rahi me te rahi ki nga waahanga whakarewa e hiahiatia ana. Mo nga mahi whakarewa kirikiri me nga tikanga whakarewanga haumi, ka taea te whakamahi ano i te kirikiri me te wax. I te nuinga o te waa he pai ake te mata, te hangahanga me te ahu i te kirikiri kirikiri.
Kua wehea nga whakamaaramatanga maka ki roto i nga Whakaaetanga Makanga Ahu (DCT) me nga Whakaaetanga Makanga Geometrical (GCT). 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 ko nga reanga whaanui ka taea e taatau ma te maka o te kirikiri kaakaariki, te whakarewa anga maata me te whakarewanga onepu kapia kore tunu:
✔ Koeke DCT na te Maka Kirikiri Kakariki: CTG10 ~ CTG13
✔ Koeke DCT na te Anga Mourangi Maka, Furan Resin Sand Maka ranei: CTG8 ~ CTG12
✔ Koeke GCT na te Maka Kirikiri Kakariki: CTG6 ~ CTG8
✔ Koeke GCT na te Anga Mold Maka, Furan Resin Sand Maka ranei: CTG4 ~ CTG7
Nga Painga o te Tikanga Makanga kirikiri
1- He iti te utu na te iti me te hangarua o nga taputapu hangarua me nga taputapu hanga ngawari.
2- Te whānuitanga o te taumaha o te waeine mai i te 0.10 kg ki te 500 kgs, nui ake ranei.
3- Nga momo Hanganga mai i te momo ngawari ki te momo uaua.
4- He pai mo nga whakaritenga whakaputa o nga rahinga rereke.
