1. Ko te ōwehenga pēhi o te tīwiri whakaputa tīwiri kotahi e tika ana i waenga i te 1:2-1:3, ko te 1:2.5 te pai, ā, ko te ōwehenga roa ki te whānui tino pai o te tīwiri e toru-wāhanga ko te 25. Mā te hoahoa tīwiri pai ka taea te karo i te pirau rauemi me te pakaru i puta mai i te waku nui. Ki te whakaaro ko te roa o te tīwiri he L, ko te wāhanga whāngai he 0.3L, ko te wāhanga pēhi he 0.4L, ko te wāhanga ine he 0.3L, ā, ko te āputa i waenga i te oko tīwiri me te tīwiri he 0.1-0.2mm. Me whai kōhao 1.5-5mm te pereti honikoma i te pane o te mīhini, mā te whakamahi i ngā tātari e rua 400 kōhao/cmsq (tata ki te 50 mata). I te wā e whakaputa ana i ngā whitiki pakihiwi mārama, me whakamahi he motuka kaha ake hei ārai i te tūnga o te motuka, te wera rānei nā te taumaha rawa. I te nuinga o te wā, kei te wātea ngā tīwiri PVC, BM rānei, engari kāore e tika ana ngā tīwiri wāhanga pēhi poto.
2. Ko te pāmahana whakahāngai ka whakawhirinaki ki ngā rauemi o ngā kaihanga rerekē, ā, ki te teitei ake te pakeke, ka teitei ake te pāmahana whakaputa. Ka piki ake te pāmahana tukatuka mā te 10-20 ℃ mai i te wāhanga whāngai ki te wāhanga ine.
3. Mena he tere rawa te tere o te tīwiri, ā, kua wera rawa te waku nā te ahotea kutikuti, me whakahaere te tautuhinga tere i waenga i te 12-60rpm, ā, ko te uara motuhake ka whakawhirinaki ki te diameter o te tīwiri. Ko te nui ake o te diameter, ko te puhoi ake o te tere. He rerekē ia rauemi, ā, me aro ki ngā whakaritenga hangarau a te kaiwhakarato.
4. I mua i te whakamahinga, me horoi pai te tīwiri, ā, ka taea te whakamahi i te PP, i te HDPE rānei hei horoi i ngā pāmahana teitei ake. Ka taea hoki te whakamahi i ngā kaihoroi hei horoi.
5. Me whakarite kia ātaahua te hoahoa o te pane o te mīhini, ā, kaua e puta he kokonga mate hei whakarite kia maeneene te rere o ngā rauemi. Ka taea te whakaroa i te rārangi whāriki o te ringaringa pokepokea, ā, ko te koki i waenganui i ngā ringaringa pokepokea kua hangaia kia 8-12°, he pai ake tēnei hei whakaiti i te ahotea kutikuti, hei ārai i te paru kanohi i te wā whakaputa, hei whakaū hoki i te nui o te whakaputanga.
6. He nui te tauwehenga o te waku o te TPU, ā, he uaua ki te hanga. Me roa ake te roa o te tāke wai whakamatao i ētahi atu rauemi kirihou wera, ā, he māmā ake te hanga i te TPU he pakeke rawa.
7. Me maroke te waea matua, ā, me kore he paru hinu hei ārai i ngā mirumiru i te wera. Ā, kia pai ai te whakakotahitanga.
8. Kei roto te TPU i te kāwai o ngā rauemi ngāwari ki te waikura, e tere mimiti ana i te makuku ina whakatakotoria ki te hau, inā koa he waikura ake ngā rauemi e hangai ana ki te ether i ngā rauemi e hangai ana ki te polyester. Nō reira, me whakarite kia pai te āhua hiri. He ngāwari ake te mimiti o ngā rauemi ki te makuku i raro i ngā āhuatanga wera, nō reira me tere hiri ngā rauemi e toe ana i muri i te takai. Whakahaerehia te ihirangi makuku i raro i te 0.02% i te wā tukatuka.
