Hoʻolauna kaʻina hana

Hana ʻia ka 3/4 o nā huahana i hoʻoheheʻe ʻia e ka extrusion blow molding.ʻO ke kaʻina hana extrusion e hoʻoikaika i ka mea i loko o ka lua a i ʻole ka make e hana i kahi huahana.

ʻO ke kaʻina hana hoʻoheheʻe extrusion he 5 mau ʻanuʻu: 1. Plastic preform (extrusion o hollow plastic tube).2. E pani i ka mold flap ma ka parison, e hoopili i ka mold a oki i ka parison.3. E puhi i ka poni i ka paia anuanu o ka lua, e hoʻoponopono i ka wehe a mālama i kekahi kaomi i ka wā hoʻomaha.4. E wehe i ka ʻōpala a wehe i nā ʻāpana puhi.5. E ʻoki i ka uila no ka loaʻa ʻana o ka huahana i pau.

Kaʻina hana hollow blow hollow
Extrusion hollow blow molding mea e hoohehee a plasticize i ka plastic i loko o ka extruder, a laila extrude i ka tubular parison ma o ka tubular make.Ke hiki ka parison i kahi lōʻihi, hoʻomehana ʻia ka parison i loko o ka mold blow.Hoʻopili ʻia ka ea i hoʻopaʻa ʻia e hana i ka parison kokoke i ka paia o ka lua mold e kiʻi i ke ʻano o ka lua, a ma lalo o ke ʻano o ka mālama ʻana i kekahi kaomi, ma hope o ka hoʻoluʻu ʻana a me ka hoʻohālikelike ʻana, loaʻa ka huahana puhi ʻia ma ka demolding.Penei ke kaʻina hana o ka extrusion blow molding.
Plastic → plasticizing a extrusion → tubular parison → mold pani → inflation molding → cooling → mold opening → lawe i ka huahana
Hiki ke hoʻokaʻawale ʻia ka hoʻoheheʻe extrusion i nā ʻanuʻu ʻelima aʻe, e like me ka hōʻike ʻana ma ka Figure 1-1.
① Hoʻoheheʻe ʻia ka polymer ma o ka extruder, a hoʻoheheʻe ʻia ka heheʻe i loko o kahi parison tubular ma o ka make.
②Ke hiki ka parison i ka lōʻihi i koho mua ʻia, ua pani ʻia ka pā, ua hoʻopaʻa ʻia ka parison ma waena o nā ʻāpana ʻelua, a ʻoki ʻia ka parison a neʻe i kahi keʻena ʻē aʻe.
③E hoʻokomo i ka ea i hoʻopaʻa ʻia i loko o ka parison e hoʻonui ai i ka parison e hoʻokokoke i ka lua e hana ai.
④ Hoʻomaha.
⑤Wehe i ka ʻōpala a lawe i waho i ka huahana i hoʻoheheʻe ʻia.
