Hoʻolauna Mīkini Puhi

Ua kapa ʻia ʻo Extrusion blow molding machine he hollow blow molding, kahi ʻano hana hana plastik e ulu wikiwiki nei.ʻO ka tubular plastic parison i loaʻa ma ka extrusion a i ʻole injection molding o ka thermoplastic resin e waiho ʻia i loko o kahi ʻāpana i ka wā wela, a hoʻokomo ʻia ka ea i hoʻopaʻa ʻia i loko o ka parison ma hope koke o ka pani ʻia ʻana o ka mold e hoʻoulu i ka parison plastik a pili i ka paia o loko. o ka popopo.Ma hope o ka hoʻoluʻu a me ka demoulding, hiki ke loaʻa nā huahana hollow like ʻole.ʻO ke kaʻina hana o ka puhi kiʻiʻoniʻoni he mea like loa ia ma ke kumu me ka hoʻoheheʻe ʻana i nā huahana hollow, akā ʻaʻole ia e hoʻohana i ka mold.Mai ka hiʻohiʻona o ka hoʻokaʻawale ʻana i ka ʻenehana hana plastik, hoʻokomo pinepine ʻia ke kaʻina hana hoʻoheheʻe ʻia o ke kiʻi ʻoniʻoni i ka extrusion.Ua hoʻohana ʻia ke kaʻina hana puhi e hana i nā hue polyethylene haʻahaʻa haʻahaʻa i ka wā o ke Kaua Honua ʻElua.I ka hopena o nā makahiki 1950, me ka hānau ʻana o ka polyethylene kiʻekiʻe a me ka hoʻomohala ʻana o nā mīkini hoʻoheheʻe ʻana, ua hoʻohana nui ʻia ka ʻenehana puhi puhi.Hiki i ka leo o ka ipu hollow ke hiki aku i mau tausani lita, a ua lawe kekahi hana i ka mana kamepiula.ʻO nā plastik kūpono no ka hoʻoulu ʻana he polyethylene, polyvinyl chloride, polypropylene, polyester, a me nā mea ʻē aʻe.E like me ke ʻano hana o ka parison, hiki ke hoʻokaʻawale ʻia ka hoʻoheheʻe ʻana i ka extrusion blow molding a me ka injection blow molding, a me ka hoʻomohala hou ʻana i ka multi-layer blow molding a me ka stretch blow molding.

Hoʻokaʻawale mīkini

Hiki ke hoʻokaʻawale ʻia nā mīkini puhi puhi i ʻekolu mau ʻāpana: extrusion blow molding machines, injection blow molding machines and special structure blow molding machines.Hiki ke pili i nā mīkini hoʻoheheʻe ʻana i kēlā me kēia o nā ʻāpana i luna.ʻO ka mīkini hoʻoheheʻe extrusion ka hui pū ʻana o ka extruder, ka mīkini hoʻoheheʻe ʻana a me ka mīkini hoʻopili.Hoʻokumu ʻia ia me ka extruder a me ka parison die, ka mea hoʻonui, ka mīkini hoʻopili mold, ka ʻōnaehana mānoanoa parison a me ka mīkini hoʻouna.ʻO ka parison die kekahi o nā mea nui e hoʻoholo ai i ka maikaʻi o nā huahana i hoʻoheheʻe ʻia, a maʻa mau ka make ʻaoʻao ʻaoʻao a me ka make ʻai waena.Ke hoʻoheheʻe ʻia nā huahana nui, hoʻohana pinepine ʻia ka make ʻano billet storage cylinder type.Loaʻa i ka pahu waihona ka liʻiliʻi o 1kg a me ka nui loa o 240kg.Hoʻohana ʻia ka mīkini parison mānoanoa e hoʻomalu i ka mānoanoa pā o ka parison.Hiki i nā helu hoʻomalu ke piʻi i 128 mau helu, maʻamau 20-30 mau helu.Hiki i ka extrusion blow molding machine ke hana i nā huahana hollow me ka nui mai 2.5ml a 104l.

ʻO ka mīkini hoʻoheheʻe hoʻoheheʻe ʻia ka hui pū ʻana o ka mīkini hoʻoheheʻe ʻia a me ka mīkini hoʻoheheʻe ʻana, me ka mīkini plasticizing, ka ʻōnaehana hydraulic, ka mana uila a me nā ʻāpana ʻē aʻe.ʻO nā ʻano maʻamau he ʻekolu-station injection blow molding machine a ʻehā-station injection blow molding machine.ʻEkolu mau kikowaena ka mīkini kikowaena ʻekolu: prefabricated parison, inflation a demoulding, a ua hoʻokaʻawale ʻia kēlā me kēia kikowaena e 120 °.ʻO ka mīkini hoʻonohonoho ʻehā he hoʻokahi kikowaena preforming, a ʻo kēlā me kēia kikowaena he 90° kaawale.Eia kekahi, aia kahi mīkini pahu hoʻoheheʻe pālua me ka 180 ° kaʻawale ma waena o nā kikowaena.ʻO ka ipu plastik i hana ʻia e ka mīkini hoʻoheheʻe injection he ʻano kikoʻī a ʻaʻole koi i ka hana lua, akā ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka mold.ʻO ka mīkini hoʻoheheʻe hoʻolālā kūikawā he mīkini hoʻoheheʻe e hoʻohana ana i nā lau, nā mea hoʻoheheʻe ʻia a me nā blanks anu e like me nā parisons e puhi i nā kino hollow me nā ʻano a me nā hoʻohana kūikawā.Ma muli o nā ʻano like ʻole a me nā koi o nā huahana i hana ʻia, ʻokoʻa hoʻi ke ʻano o ka mīkini puhi puhi.
