1. Anga matua:
Ko te tinana mīhini waipēhi momo-anga he hanganga anga whakauru, he mea hanga mai i ngā wāhanga hanganga maitai kua whakarewahia, me ngā matapihi taha e waiho ana i waenganui o ngā pou maui me matau, mā te whakamahi i te hanganga whakarewa pereti maitai kounga teitei Q355B, he whakarewa kua tiakina ki te hau waro hauhā; i muri i te whakarewa, me haere mā te maimoatanga whakamahana kia kore rawa e huri te āhua me te ahotea o te whakarewa, kia mau ai te pakari o ngā wāhanga kua whakarewahia, kia kore ai e huri te āhua, ā, kia mau tonu te tika. Ko te kurupae o raro, ngā pou, me te kurupae o runga kua whakakīia ki mua e ngā tokotoko here (whakakī-mua waipēhi) hei hanga i tētahi anga whakakotahi; he poraka reti kei waenganui o te tinana, ā, ko te poraka reti e arahina ana e te arataki arataki kokonga-whā me te waru-āhua momo-poro, ā, ko te pereti arataki poraka reti he mea hanga ki te rauemi hiato A3+CuPb10Sn10, ko te arataki arataki o te pou e whakamahi ana i tētahi arataki arataki ka taea te tango.

①Te kurupae o runga me te kurupae o raro: Ka whakarewaina te kurupae o runga me te kurupae o raro ki te pereti maitai Q355B, ā, ka whakakorea te ahotea o roto i muri i te whakarewatanga hei whakarite i te pumau o te hanganga me te tika o te taputapu tonu. Ka mīhinihia he kōhao tāutanga rango matua ki te kurupae o runga. Ka tāutahia he rango urunga waipēhi me te urunga waipēhi ki roto i te kurupae o raro.

② Pou: Ka whakarewaina te pou mā te pereti maitai Q355B, ā, i muri i te whakarewanga, ka mahia te maimoatanga whakaiti ahotea. Ka tāutahia he poraka arataki reti ka taea te whakarite ki runga i te pou.

③Rākau here me te nati raka: Ko te rauemi o te rākau here me te nati raka he maitai 45#. Ka honoa te rākau here ki te miro raka uwha, ā, ka whakakīia i mua e te taputapu whakakī-mua pēhanga teitei rawa hei raka i te tinana.

2. Rēreti:
He pereti rino te hanganga o te reti, he āhua pouaka, he mea whakarewa, ā, ko te papa raro o te reti he wahi pereti rino katoa hei whakarite kia pakari, kia kaha hoki. Ko te reti o te mīhini pēhi waipēhi momo-anga mō te anga hanga uhi waka he whakamahi i ngā ara ārahi e whā-koki me waru-taha. E whā ngā huinga poraka arataki i ngā pou maui me matau. Ka neke poutū ngā pereti arataki o te reti i runga i ngā ara ārahi, ā, ko te tika o te arataki nekehanga e whakawhirinaki ana ki ngā ara ārahi reti. Ka whakamahia te rino piko hei whakarite kia rite te āhua ki te tēpu mahi neke, kia watea te whakarite, kia tika te whakarite, kia mau tonu te tika i muri i te whakaritenga, me te kaha kaha ki te ārai i te kawenga rerekē. Kotahi te taha o te takirua waku o te reti arataki he mea hanga ki te rauemi koranu, ā, ko tetahi taha he mea hanga ki te rauemi koranu parahi. Hei tāpiri, kua tineihia te reti arataki, he pakeke ake i te HRC55, he pai te ātete ki te kakahu me te roa o te ora mahi. Kua whakaratohia he kōhao whakahinuhinu ki te mata o te reti reti mō te whakahinuhinu aunoa kia whakahinuhinuhia ai ngā wāhanga neke. Ka tutuki te whakatikatika pai o te reti mā te whakahaere i te takirere rere ōwehenga, e whakamahia ana mō te whakatikatika pai me te whakapiri pokepokea ai i te wā e tīpakohia ana te pokepokea ai, ā, ka taea te whakatikatika i roto i te awhe o te 0.5-2mm/s.

3. Te neke i te tēpu mahi:
Ko te mīhini pēhi waipēhi momo-anga mō te hanga i ngā taupoki anga tinana waka he tēpu mahi neke whakamua. Ko te tēpu mahi neke he hanganga whakarewa pereti maitai Q355B. Whai muri i te whakarewa, ka mahia te maimoatanga whakaiti ahotea. Ka tukatukahia te tēpu mahi neke ki ngā awaawa "T" me ngā kōhao ejector. Ko ngā rahi o te awaawa "T" me te kōhao pine ejector ka hangaia kia rite ki te tuhi tahora i whakaratohia e te Rōpū A. Waiho kia 400mm i waenganui o te awaawa "T" me te kore e mira. He tokotoko ejector me te taupoki puehu e rite ana, ko te pakeke maimoatanga wera o te tokotoko ejector kei runga ake i te HRC42 nekehanga. Ko te tika o te tūnga auau o te tēpu mahi neke he ±0.05mm, ā, ko te aratau taraiwa he mea whakarite ki te whakaiti tere, ā, he hanganga neke-whaiaro. Me te taputapu kimi whakauru, ina nui ake te āputa i waenga i te papa o raro o te tēpu mahi neke me te papa o raro o te kurupae o raro i te 0.3mm, kāore e whakaaetia te manaaki ki te mahi. Whakaratohia ngā taupoki kōhao mandrel katoa. He mokowā mate ripeka kei te papa o te tēpu mahi, ko te rahi he 14mm te whānui ki te 6mm te hohonu.

4. Puoto Matua:
He hanganga maha-puoto te rango hinu matua e whakakotahi ana i te rango piston me te rango plunger. He mea hanga te tokotoko piston ki te maitai hanganga waro kounga teitei, ā, ka tineia te mata hei whakanui ake i te pakeketanga; he mea hanga te tinana rango ki te maitai hanganga waro kounga teitei hei whakarite i te ōritetanga o ngā rauemi, ā, he mowhiti hiri kounga teitei kawemai te rango hinu.

5. Puoto urunga waipēhi:
Kei roto i te kurupae raro o te mīhini perehi waipēhi momo-anga he taputapu rango urunga waipēhi hei hanga i te anga o te taupoki anga o te tinana waka. E rua ngā mahi a te urunga waipēhi: he urunga waipēhi, he mea pana rānei, ka taea te whakamahi hei whakarato i te kaha pupuri kore i te wā e totoro ana te pereti maitai, hei pana rānei. Ko te hua, he hanganga karauna kotahi te urunga waipēhi, ā, he pūoko nekehanga raina tōna. Ka taea e te mīhini perehi te whakatutuki i te tautuhinga matihiko o te tūranga hurihanga whiu o te reti me te urunga waipēhi, ā, he māmā noa iho, he whai hua hoki te whakahaere.

6. Nekehia te tēpu mahi hei hiki i te rango whakapūmau:
He hanganga momo piston ngā rango hiki me te whakapiri e whā o te mīhini pēhi waipēhi momo-anga mō te hanga uhi anga tinana waka. Kua tāutahia ēnei ki te kurupae whakawhiti o raro. Ka taea te hiki i te tēpu neke ina ara ake, ā, ka taea te whakapiri i te tēpu neke ina tukua iho. Kei runga ake i te kurupae o raro.

7. Puoto whakapūmau:
Ka whakaritea he taputapu ārai wero i runga i te hiahia, he mea tito mai i tētahi rango ārai, he pūnaha ārai me tētahi tikanga hono, ā, ka tāutahia ki te taha o runga o te kurupae o raro o te mīhini perehi hei tapahi taha, hei wero me ētahi atu tukanga wero. Ka taea e te rango ārai me te pūnaha ārai te mimiti i te ru me te whakakore i te wiri i te wā e wero ana.
