2. Te Tukatuka me te Whakarite i ngā Mandrel Whakarewa

• Te Hiranga o ngā Mandrels Whakarewa

I mua i te tīmatanga o te tukanga takai ngongo, ko te taahiraa tuatahi ko te whakarite i ngā mandrel whakarewa. Me ōrite te diameter o roto o ngā mandrel whakarewa ki te diameter o roto o ngā ngongo, ā, he mea nui te maeneene o te mata me te maimoatanga tika. Hei tāpiri, me tika te maimoatanga o mua o ngā mandrel whakarewa, pērā i te horoi me te paninga i tētahi kaihoko tuku, hei whakahaere i te tukanga tangohanga e whai ake nei.

I te wā e takai ana te ngongo, he mea nui te mahi a te mandrel whakarewa nā te mea me tautoko e ia temuka waro prepregkia maeneene ai te takai. Nō reira, he mea nui te whakarite i te rahi e tika ana mō te mandrel whakarewa i mua. Nā te mea ka takaihia te muka waro ki te mata o waho o te mandrel, me ōrite te diameter o waho o te mandrel ki te diameter o roto o te ngongo muka waro e hangaia ana.

• Te tono i te kaihoko tuku

Ka whakaitihia e ngā matū tuku te waku, ā, ka whakarite kia maeneene te tangohanga; me pania ōrite ki te mata o te mandrel. Kia oti te whakarite i te mandrel whakarewa, ko te mahi e whai ake nei ko te pania o te matū tuku. Ko ngā matū tuku e whakamahia whānuitia ana ko te hinu silicone me te paraffin, e whai hua ana ki te whakaiti i te waku i waenga i te muka waro me te mandrel whakarewa.

Me whakarite kia tino ma te mapere whakarewa kua oti te whakarite, kia maeneene hoki te mata kia pai ai te tango i te hua. Muri iho, me pania te matū tuku ki te mata o te mapere kia ōrite.

3. Te whakarite i te muka waro i mua i te whakatō
