He aha nā ʻano hana hollow blow?

Hollow blow molding method introduction:

Ma muli o ka ʻokoʻa o nā mea maka, nā koi hana, nā huahana a me nā kumukūʻai, ʻokoʻa nā ʻano hana hoʻoheheʻe ʻana i nā pono like ʻole i ka hana ʻana i nā huahana like ʻole.

ʻO ka hoʻoheheʻe ʻana i nā huahana hollow he ʻekolu mau ala nui:

1, extrusion blow molding: hoʻohana nui ʻia no ka hana billet i kākoʻo ʻole ʻia;

2, ka hoʻoheheʻe ʻana i ka puhi ʻana: hoʻohana nui ʻia no ka hana ʻana i ka billet i kākoʻo ʻia e ke kumu metala;

3, hoʻoheheʻe ʻia: e komo pū me ka extrusion a stretch blow molding, injection a stretch blow molding ʻelua ʻano, hiki ke hana i nā huahana biaxial oriented, hoʻemi nui i nā kumukūʻai hana a hoʻomaikaʻi i ka hana huahana.

Eia kekahi, he nui ka hoʻoheheʻe ʻana o ka pā, kaomi ʻana i ka puhi ʻana, ka hoʻoheheʻe ʻana i ka uhi ʻana i ka puhi ʻana, ka hoʻoheheʻe ʻana o ka pua, ʻekolu-dimensional blow molding, etc. ʻO ka hoʻoheheʻe ʻana a me ka 1% he mau mea hoʻoheheʻe ʻē aʻe.ʻO nā huahana hoʻoheheʻe puhi āpau, ʻo 75% ka mea i nā huahana bidirectional stretch.ʻO nā mea maikaʻi o ka extrusion blow molding he kiʻekiʻe ka hana hana, haʻahaʻa haʻahaʻa haʻahaʻa, ākea ākea o ka mold a me ke koho mīkini, nā hemahema he kiʻekiʻe kiʻekiʻe o ka ʻōpala, ka hoʻoheheʻe ʻana i ka ʻōpala, ka hoʻohana maikaʻi ʻole, ka mana o ka mānoanoa o ka huahana, ua kaupalena ʻia ka laha ʻana o nā mea maka, ma hope o ka hoʻoheheʻe ʻana. e hoʻoponopono i ka hana lihi.ʻO nā mea maikaʻi o ka hoʻoheheʻe ʻana i ka injection ʻaʻole ia he ʻōpala i ke kaʻina hana, hiki ke hoʻomalu maikaʻi ʻia ka mānoanoa o ka pā o nā huahana a me ka hoʻopuehu ʻana o nā mea, ke kiʻekiʻe o ka pololei o nā huahana ʻāʻī lahilahi, maʻalahi ka ʻili o nā huahana, a hiki ke hoʻokō ʻia ka hana ʻoihana liʻiliʻi.ʻO ka hemahema ke kumu kūʻai kiʻekiʻe o nā mea hana hoʻoheheʻe, a i kekahi ʻano kūpono wale nō no nā huahana pā liʻiliʻi.

ʻO nā kūlana kaʻina o ka hollow blow molding e pono e maʻemaʻe ka ea i hoʻopili ʻia o ka billet medium of blow mold.He 0.55 ~ 1MPa ka puhi ʻana i ka ea;He 0.2L ~ 0.62mpa ke kaomi hoʻoheheʻe ʻana o ka puhi ʻana, ʻoiai ke koi pinepine ʻia ke kiʻekiʻe e like me 4MPa.I ka paʻa paʻakiki, hoʻohaʻahaʻa ka haʻahaʻa haʻahaʻa i ke koʻikoʻi o loko o nā huahana, ʻoi aku ka like o ka hoʻopuehu ʻana o ke kaumaha, a hiki i ke kaumaha haʻahaʻa ke hoʻomaikaʻi i ka tensile, hopena, kūlou a me nā waiwai ʻē aʻe o nā huahana.
