Makanga haumi, e mohiotia ana hoki ngaro ware pi maka raneite whakarewanga tika, e pa ana ki te hanganga o te uku huri noa i nga tauira ware pi ki te hanga i tetahi maaka maha, kotahi waahanga ranei hei tango i te whakarewa whakarewa. Ka whakamahia e tenei tukanga he tukanga tauira ware pi i werohia hei whakatutuki i nga ahua uaua me nga kounga o te mata. Hei hanga i te pokepokea ai, he tauira ware pi, he huinga tauira ranei, ka toua ki roto i nga mea uku kia maha nga wa hei hanga anga matotoru. Ko te mahi whakakore wax ka whai i te tukanga whakamaroke anga. Ka mahia te anga uku iti-wax. Ka ringihia te konganuku whakarewa ki roto i nga kohao anga uku, tautau ranei, a, ka pakari, ka whakamatao, ka whati te anga uku kia kitea te mea whakarewa whakamutunga. Ka taea e nga whakarewanga haumi te whakatutuki i te tino tika mo nga waahanga whakarewa iti me te rahi i roto i te whānuitanga o nga rauemi.
Nga Waahi o te Tukatuka Makanga Whakangao:
I te wa o te mahi makanga whakangao, ka whakakikoruatia he tauira ware pi ki te taonga uku, ka whakapakeketia, ka mau ki te ahuahanga o roto o te whakarewanga e hiahiatia ana. I te nuinga o nga wa, he maha nga waahanga ka maka tahi mo te tino pai ma te whakapiri i nga tauira ware pi takitahi ki te rakau wax pokapū e kiia nei ko te sprue. Ka rewa te wax i roto i te tauira - na reira i mohiotia ai ko te tukanga wax ngaro - ka ringihia te whakarewa whakarewa ki roto i te rua. Ka pakari te whakarewa, ka whakangaueuetia te maaka uku, ka waiho te ahua kupenga tata o te makanga e hiahiatia ana, ka whai i te whakaoti, te whakamatautau me te takai.
He aha e whakamahia ana nga utu haumi?
Nga whakangao haumie whakamahia nuitia ana i roto i nga papua me nga vaolo, motuka, taraka, waipēhi, taraka marau me te maha atu o nga umanga. Na te tino pai o te whakarewanga me te whakaotinga pai, ka nui ake te whakamahia o nga whakarewanga ware pi kua ngaro. Ina koa, he mea tino nui nga whakarewanga whakangao kowiri tira i roto i te hanga kaipuke me nga poti na te mea he kaha te mahi anti-waikura.
He maha nga take hei whiriwhiriRMC whakangao whakangao whakarewahei puna mo nga whakangao haumi, ko enei ko:
- Hangarau pokapu me te arotahi whakarewa
- He wheako nui ki nga ahuahanga matatini me nga waahanga uaua-ki-hanga
- He maha nga momo rauemi, tae atu ki nga koranu ferrous me te kore-ferrous
- Nga kaha miihini CNC i roto i te whare
- Nga otinga kotahi-mutu mo nga whakarewanga haumi me nga mahi tuarua
- Ko te kounga rite tonu te whakamana
- Te mahi a te roopu tae atu ki nga kaihanga taputapu, miihini, kaiwhakarewa, miihini me nga tohunga hangarau.
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.
