Rahi noa:
Ka tukuna e mātou ngā hua i te āhua o te waea, te waea papatahi, te waea rīpene. Ka taea hoki e mātou te hanga rauemi ritenga kia rite ki ngā tono a te kaiwhakamahi.
Waea kanapa, kua whakamahanatia, ngohengohe–0.025mm~5mm
Waea mā te whakapūkara waikawa: 1.8mm~10mm
Waea waikura: 0.6mm ~ 10mm
Waea papatahi: matotoru 0.05mm~1.0mm, whānui 0.5mm~5.0mm
Tukanga:
Waea: Te whakarite rauemi→te whakarewa→te whakarewa anō→te hanga→te hurihuri wera→te whakamahana wera→te whakamahana mata→te tuhi (te hurihuri)→te whakaoti whakamahana wera→te tirotiro→te mōkihi→te whare putunga
Ngā āhuatanga o te hua:
1) He tino pai te ātete ki te waikura me te kaha miihini i te pāmahana teitei;
2) Te ātete teitei me te tauwehenga pāmahana iti o te ātete;
3) He tino pai te hurihanga me te mahi hanga;
4) He mahi whakarewa pai rawa atu
Te whakamahinga o ngā māka katoa:
NiCr 80/20: i roto i ngā ātete aukati, ngā oumu ahumahi, ngā rino papatahi, ngā mīhini rino, ngā whakamahana wai, ngā mate whakakikorua kirihou, ngā rino whakapiri, ngā huānga ngongo whakakikoruatia ki te konganuku me ngā huānga kātere.
NiCr 70/30: i roto i ngā oumu ahumahi. he pai mō te whakaiti i te hau, nā te mea kāore e pāngia e te 'pirau matomato'.
NiCr 60/15: i roto i ngā ātete aukati, ngā oumu ahumahi, ngā pereti wera, ngā oumu tunu kai, ngā oumu tōhi me ngā whakamahana rokiroki. Mō ngā koiri iri i roto i ngā whakamahana hau i roto i ngā whakamaroke kakahu, ngā whakamahana hau, ngā whakamaroke ringa.
NiCr 35/20: i roto i ngā ātete aukati, ngā oumu ahumahi. I roto i ngā whakamahana rokiroki pō, ngā whakamahana whakawhiti hiko, ngā rheostat mahi taumaha me ngā whakamahana hau. Mō te whakamahana i ngā taura me ngā whakamahana taura i roto i ngā wāhanga whakarewa me te tango hukapapa, ngā paraikete hiko me ngā papa, ngā nohoanga motuka, ngā whakamahana papa raro me te whakamahana papa.
NiCr 30/20: i roto i ngā pereti wera totoka, ngā whakamahana koiri tuwhera i roto i ngā pūnaha HVAC, ngā whakamahana rokiroki pō, ngā whakamahana kawe hiko, ngā rheostat mahi taumaha me ngā whakamahana hau. Mō te whakamahana i ngā taura me ngā whakamahana taura i roto i ngā wāhanga whakarewa me te tango hukapapa, ngā paraikete hiko me ngā papa, ngā nohoanga motuka, ngā whakamahana papa raro, ngā whakamahana papa me ngā ātete.
