He kuleana koʻikoʻi nā pā pālua māhoe pālua i ka hana ʻana i nā paipu PVC a me nā profiles. ʻO kāna mau hoʻohana ʻana i kēia mau ʻāpana ʻelua i helu ʻia ma lalo nei: Plasticization a me ka hui ʻana o nā mea: Hoʻoheheʻe piha ka pahu wili a hoʻohui i ka resin PVC a me nā mea hoʻohui ʻē aʻe ma o ka wili wili a me ka wahi wela. ʻO kēia ka mea e palupalu ai ka mea PVC a maʻalahi ke hana a hoʻohālikelike. Hoʻoheheʻe Extrusion: Ma lalo o ka hana o ka pahu screw, hoʻoheheʻe ʻia ka mea PVC i hoʻoheheʻe ʻia ma o ka make e hana ai i kahi huahana tubular a i ʻole nā mea kikoʻī.
ʻO ka hoʻolālā a me ka hoʻoponopono ʻana o ka pahu screw hiki ke hana i nā paipu a me nā profiles o nā ʻano like ʻole a me nā nui. Hoʻomaʻalili a paʻa: Ma hope o ka hoʻokuʻu ʻia ʻana, hele ka paipu a i ʻole ka ʻaoʻao i ka hoʻoluʻu wikiwiki ma o kahi ʻōnaehana hoʻomaha e hoʻopaʻa i ka mea a mālama i kona ʻano. ʻOki a ʻokiʻoki: E hoʻohana i nā mea hana e like me nā mīkini ʻoki a me nā mīkini ʻokiʻoki e hoʻoponopono i ka nui a hoʻopau i ke kaʻina hana o nā paipu extruded a me nā profiles. I ka pōkole, ʻo ka pahu pālua twin-screw pāʻani ke kuleana nui i ke kaʻina hana o nā paipu PVC a me nā profiles, e ʻike ana i ka plasticization, ka hui ʻana, extrusion molding a me ka hana ʻana o nā mea, e hōʻoia ana i ka maikaʻi a me ka hana o ka huahana hope.
