| Whakamātautau UT maitai taputapu: |
Ka whakamātauhia te maitai taputapu mahi wera 1.7729 ki te ultrasonic (UT) hei whakarite i te pakari me te pono o roto mō ngā tono nui. Ka kitea e te whakamātautau UT ngā hapa o roto pērā i ngā whakaurunga, te porosity, ngā kōhao whakaheke, ngā kapiti rānei ka whakararu i te mahi a te maitai i raro i ngā ahotea wera me te miihini teitei. Ka mahia te tirotiro i runga anō i ngā paerewa o te ao, mā te whakamahi i ngā probes kua whakatikatikaina hei aromatawai i te wāhanga whakawhiti katoa. Ko ngā rauemi kore hapa anake me te hanganga o roto ōrite ka whakaaetia, e whakamana ana i te pakari teitei, te ātete pai ki te ngenge wera, me te kounga ōrite mō te maka mate, ngā mate extrusion, me ngā taputapu hanga wera.
