ʻO ka wehewehe pōkole:

ʻO ke kuleana o ka paipu komo

Ua hana mau ʻia nā intake manifolds no nā ʻōnaehana mana kaʻa.Ma muli o ke ʻano paʻakikī o ka manifold, ua hoʻolei ʻia ma mua me ka alumini alumini, akā ʻo ka paia o loko, ʻo ia ka paʻa o ka ea i ka wā o ka hoʻohana ʻana he nui, a nui ka walaʻau, e hopena i ka lawa ʻole o ka puhi ʻana a me ka nui o ka hoʻokuʻu ʻana.Mai ka 1980s, hoʻomaka ʻo ʻEulopa e hoʻohana i ke ʻano hana hana kumu i nalowale (CoreMelt).

ʻO ka manifold i hana ʻia ma kēia ʻano, ʻaʻole ia he pipiʻi wale nō, akā loaʻa nō hoʻi kahi helu hōʻole, no ka mea, ʻo ka mea o ka manifold he PA66 (a i ʻole PA6) ma hope o ka hoʻoikaika ʻana i ke aniani fiber., ʻO ka mahana hana he 250 a 260 ° C, ʻoiai ʻo ka manawa hoʻopili me ke kumu i loko o ka mold he mau minuke wale nō, akā ʻo kahi hapa o ke kumu i hiki ʻole ke hoʻoheheʻe ʻia, he mea paʻakikī ke kāohi i ka nui o ka paia o loko o ka manifold. .I nā makahiki i hala iho nei, ma muli o ka hoʻomohala ʻana o ka ʻenehana welding vibration, ʻo ka ʻenehana welding o ka fiber glass fiber reinforced PA66 e lilo i mea makua.

No kēia kumu, hiki ke hoʻopili ʻia ka manifold i ʻelua ʻāpana o nā ʻāpana manifold, i hoʻohui ʻia e ka welding vibration.Hoʻohana ka hapa nui o nā mea hana kaʻa o ka honua i kēia ʻano hana e hana i nā manifolds, plasticizing metal manifolds.
