Ko te tukanga whakaputa katoa o ngā pounamu pupuhi-whakakotahi (hei tauira, ko te werohanga totoro werohanga kotahi-taahiraa)
Ko te kaupapa matua ko te werohanga i te parison, kātahi ka totoro tonu, ka pupuhi i te pokepokea ai ki runga i te mīhini kotahi. He tino pai tēnei tikanga mō te hanga i ngā pounamu wai kohuke PET me ngā pounamu inu kounga teitei.
Hipanga 1: Te whakarite rauemi mata me te maimoatanga i mua
Ko te rauemi e whakamahia whānuitia ana ko te PET (polyethylene terephthalate), ā, ka taea hoki te whakamahi ki te PP, PC, me ētahi atu.

Te Whakamaroke: He kaha te waiora o ngā rauemi mata PET, ā, me whakamaroke rawa i ngā pāmahana teitei (pēnei i te 150-180℃) mā te whakamahi i tētahi whakamaroke whakamaroke hei whakaiti i te nui o te makuku ki te taumata tino iti (pēnei i raro i te 0.005%). Koinei te mea nui hei whakarite kia mārama te pounamu, ā, kia kore ai e pakarukaru.

Hipanga 2: Te werohanga o te parison
Ka momihia ngā pire PET maroke ki roto i te oko o te mīhini whakakoi werohanga, ka whakamahanahia, ka whakakirihoutia kia rewa.

Ka werowerohia te rewa ki roto i te pokepokea ai parison mā te tīwiri werohanga hei hanga i tētahi parison mārama, he rite ki te ngongo whakamātautau.

Kua tino hangaia te waha o te pounamu o te parison, ā, kua tutuki te tika o ngā āhuatanga whakamutunga i tēnei wāhanga.

Hipanga 3: Te whakatikatika i te pāmahana o te parison
Ka whakawhitia te parison wera kua hangaia ki te teihana whakahaere pāmahana. I roto i tēnei tukanga, ka whakamataohia te parison kia ōrite ki te awhe pāmahana tino pai mō te totoro (tata ki te 90-110℃). Ko te ōritetanga o te pāmahana te mea nui hei whakarite i te kounga o te hanga pupuhi i muri mai.

Hipanga 4: Te totoro me te pupuhi i te whakairo
Koinei te taahiraa tino nui, ka oti i roto i te pokepokea ai pupuhi.

Te totoro whakaroa: Ka kati te pokepokea ai te pupuhi, ā, ka whakaurua he tokotoko totoro mai i runga ki raro ki roto i te parison hei totoro whakaroa ki raro o te pokepokea ai.

Te pupuhi pēhanga teitei: I taua wā anō, ka pupuhihia te hau pēhanga teitei (te nuinga o te 20-40 pae) mai i te tihi o te tokotoko totoro, ka pupuhihia te parlet ki te taha pērā i te poihau, ā, ka piri pūmau ki te pakitara o roto o te pokepokea ai pupuhi makariri.

Hipanga 5: Whakamatao, ā, whakatakotoria
Ka puritia te pounamu i raro i te pēhanga i roto i te pokepokea pupuhi, ā, ka whakamataohia mō ētahi hēkona kia mau ai tōna āhua. Ka tere te kawe atu o ngā awa whakamatao i roto i te pokepokea te wera.

Hipanga 6: Whakatuwheratia te pokepokea ai, ka tangohia
Ka whakatuwheratia te pokepokea ai, ā, ka tangohia ngā pounamu kua hangaia e te ringa miihini ka haria ki ngā tukanga e whai ake nei.

Hipanga 7: Te tukatuka-muri me te tirotiro kounga
Te kuti: Tangohia te uira taikaha (te kakau o te rauemi) mai i te waha o te pounamu.

Te kimi

Te kimi i te kaha: Kia tika te rahinga whakakī.

Whakamātautau mahi hiri: Tirohia mēnā he tika te rahi o te waha o te pounamu me te miro.

Te kimi matotoru o te pakitara: Whakamahia he ine matotoru ultrasonic hei whakarite kia ōrite te matotoru o te tinana o te pounamu, inā koa i te raro me ngā pakihiwi.

Whakamātautau pēhanga: Mō ngā pounamu inu warowaihā, me whai whakamātautau ātete pēhanga ā-roto.
