Loaʻa i ka pahu plastik nā mea maikaʻi o ka maikaʻi maikaʻi, ka pale ʻana i ka corrosion māmā, ka ikaika kiʻekiʻe, ʻaʻohe wai o ka hoʻoheheʻe ʻana, ka maikaʻi o ka maʻemaʻe, ka hoʻomaʻemaʻe maʻalahi, ka hana maʻalahi a me ka hoʻoheheʻe ʻana, kahi kūpono i ka hana civili, hoʻokele maʻalahi, ke kumu kūʻai a me ke ola lawelawe lōʻihi. e hoʻololi i nā pahu lāʻau, nā pahu pahu a me nā pahu pahu lawe kaʻa, hoʻohana nui ʻia i ka meaʻai, ka mea inu a me nā ʻoihana ʻē aʻe.Hana ʻia ma nā ʻano ʻelua.

1. Hot extrusion a me ke anu e kaomi ana

ʻO nā mea waiwai nui no ka hana ʻana i nā pahu hoʻololi plastik he polyethylene high density, copolymer polypropylene a me polyvinyl chloride.Hoʻokumu ʻia ka pahu pahu pahu pahu e ka extrusion wela a me ke ʻano kaomi anu, ʻoi aku ka liʻiliʻi o ka hoʻolimalima ʻana i nā mea hana, ka haʻahaʻa haʻahaʻa o ka ikehu, ke ʻano maʻalahi a me nā koi ʻenehana haʻahaʻa, akā haʻahaʻa haʻahaʻa haʻahaʻa, ka ʻili o ka huahana a me nā waiwai mechanical maikaʻi ʻole. hana ʻana.

ʻO ke kaʻina hana ʻenehana penei: resin batching dyeing – “melt extrusion -” storage cylinder insulation – “die casting -” hoʻopau.

2. Hoʻoheheʻe ʻia

ʻO ka pahu hoʻololi a me ka pahu plastik i hoʻohui ʻia i ka extrusion wela a me ka hoʻoheheʻe ʻana i ke anuanu, ʻo ke ʻano hana maʻamau i hoʻohana ʻia ʻo ia ka hoʻoheheʻe ʻia ʻana, ua kapa ʻia hoʻi ka hoʻoheheʻe ʻana i ka injection molding a i ʻole ka hoʻoheheʻe ʻana, kona kumu a me ka loina o ka nila a me ke ʻano hana. , no laila ua kapa ʻia kekahi poʻe i kēia kaʻina hana injection molding.He kūpono ka hoʻoheheʻe ʻana no nā ʻano thermoplastics a me kekahi mau plastic thermosetting.ʻO ka pauka a i ʻole ka palaka granular mai ka hopper o ka mīkini injection i loko o ka pahu no ka hoʻomehana ʻana, i mea e hoʻoheheʻe ai ka plastic, kahe kahe a me ka plasticity maikaʻi, a laila i loko o ka plunger (a i ʻole screw) ma lalo o ke kaomi ʻana o ka nozzle ma mua o ka. ʻO ka pahu i loko o ka lua mold me ka haʻahaʻa haʻahaʻa, ma hope o ka hoʻomaha ʻana a me ka wehe ʻana i ka mold, hiki ke loaʻa nā huahana plastik.

Penei ke kaʻina hana: hānai - hoʻomehana plasticization - injection - shaping - demold.

I kēia manawa, ʻo ka mīkini hoʻoheheʻe i hoʻohana ʻia ʻo ia ka mīkini hoʻoheheʻe hoʻoneʻe hoʻoneʻe.ʻO ka hoʻokomo ʻana i nā mea hana hoʻoheheʻe injection he nui, paʻakikī paʻakikī, kumukūʻai hana kiʻekiʻe, kūpono no ka hana nui.
