Whakataki Hua
He kaihanga a JINYO e whakauru ana i te R&D, te whakaputa, te hoko me te ratonga. Ko tana pakihi e kapi ana i ngā mara o te tuku waipēhi, ngā paipa maitai tino tika me ngā taputapu mīhini hangarau. E whakamahi ana te kamupene i te hangarau mīhini whakakoi me te huri matatau, he kaha whakaputa me te tukatuka ahurei mō te tokotoko whakakikoruatia ki te kōrome ritenga, te pae kōrome mārō, te tokotoko piston waipēhi me te ngongo rango waipēhi, ngā ngongo whakakoi, te ngongo SRB, ā, e whakapau kaha ana ki te whakarato i ngā paerewa kounga teitei me te ratonga pai rawa atu puta noa i te ao.
Ngā ratonga ritenga
He tohunga hangarau whakaputa ngaio a JINYO me ngā taputapu whakaputa matatau, ā, ka taea e rātou te whakarite i te hanga o ngā tokotoko whakakikoruatia ki te kōrome me ngā ngongo whakakoi kia rite ki ngā whakaritenga tono o ngā ahumahi rerekē. Ahakoa he whānui, he roa, he āhua mata rānei, ka taea e mātou te whakarato i ngā tokotoko whakakikoruatia ki te kōrome hei whakatutuki i ngā hiahia o tō pūnaha waipēhi.He tokotoko piston kua mīhinihia kia rite ki ngā tuhi a te kiritaki: te hurihanga, ngā chamfer, te radius o roto/o waho, ngā miro o roto/o waho, ngā kōhao toki/rodial, ngā awaawa o roto/o waho mō ngā hiri.
Haunga te whakaritenga o ngā tokotoko whakakikoruatia ki te kōromo, he tino pakari hoki ngā tokotoko whakakikoruatia ki te kōromo. Mā te mata pakari whakakikoruatia ki te kōromo ka iti te waku me te pakaru, ka taea ai e te rango waipēhi te mahi maeneene me te whai hua. Ehara i te mea ka whakapai ake i te mahi whānui o te pūnaha anake, engari ka whakaitihia hoki ngā whakaritenga tiaki, ā, ka penapenahia ngā utu me te whakapiki ake i te hua. He whānuitia te whakamahinga o ngā tokotoko whakakikoruatia ki te kōrome mō ngā pūnaha waipēhi.
