He hangarau tino whai hua te whakakī mō te hiri porosity hei whakamātautau me te whakahaere i te porosity i roto i ngā wāhanga konumohe whakarewa mate. Ka pēhia te matū piri ki roto i ngā kōhao i roto i ngā wāhanga, ka whakapakeke hei whakakī i ngā wāhi matua takoto kau, ā, ka ea pai te take porosity.
Tukanga
1. Te horoi me te tango hinu.
2. Whakatōkia ki roto i te kāpata.
3. Mā te korehau e whakahaere i raro i te pēhanga hau 0.09mpa, ka tangohia te hau mai i ngā matua kau.
4. Whakauruhia he wai piripiri ki roto i te kāpata, ka waiho kia 15 meneti pea, kātahi ka hoki te hau ki te āhua noa.
5. I ētahi wā ka hiahiatia he pūwhakakoi mō ngā wāhanga nunui hei pana i ngā matū ki roto i ngā matua.
6. Ngā wāhanga maroke.
7. Tangohia ngā mea piri i runga i te mata.
8. Whakatōkia ki roto i te totohu wai i raro i te 90℃, mō te 20 meneti.
9. Whakamātautau Pēhanga e ai ki te Whakatakotoranga.
I hangaia e Kingrun tētahi raina Impregnation hou i te marama o Hune o te tau 2022, e whakarato ana i te ratonga nui ki te umanga motuka.
I ēnei rā, kei te whakahou tonu ngā kaihoko i ā rātou hiahia kia tino tika. He nui te wāhi o tā mātou tahua ki te haumi ki ngā taputapu whai hua, engari tae noa mai ki tēnei wā kei te mahi tika ia whare i roto i te wheketere, e akiaki ana i a mātou kia anga whakamua me te matatau.
