1. ʻO ke kaʻina hana o nā huahana plastik ka hana hoʻoheheʻe ʻana i nā ʻōmole plastik, e pili ana i ke kaʻina hana i nā huahana plastik hope loa mai ka polymer i hana ʻia e ka hale hana resin synthetic.

2. ʻO nā ʻano hana (a me ka hoʻoheheʻe ʻana i ka plastic) ʻo ia ka: kaomi kaomi (molding), extrusion (extrusion molding), injection molding (injection molding), blow molding (hollow molding), calendering, etc.Specific manufacturing process:

⑴ kaomi ʻana: hoʻoheheʻe ʻia a kaomi ʻana paha.

⑵ extrusion: extrusion molding, ʻo ia ka hoʻohana ʻana i ka mīkini extrusion (extruder) e hoʻomau ʻia ka resin ma o ka mold, extrusion makemake ʻia o ke ʻano huahana. ʻO ka maikaʻi o ka extrusion ʻo ia ka hiki ke hoʻokuʻu i nā ʻano like ʻole o nā huahana, ka hana kiʻekiʻe o ka hana ʻana, ka hana maʻalahi a me ka hoʻomau ʻana; .

⑶ Hoʻoheheʻe ʻia: hoʻoheheʻe ʻia. ʻO ka hoʻoheheʻe ʻia ʻana ka hoʻohana ʻana i ka mīkini hoʻoheheʻe ʻia (a i ʻole ka mīkini injection) e heheʻe ai ke kaula thermoplastic ma lalo o ke kaomi kiʻekiʻe i loko o ka mold ma hope o ka hoʻoluʻu ʻana, paʻa i ka loaʻa ʻana o ke ʻano huahana. a me ka foam plastic rope molding.Injection molding i ka pono o ka wikiwiki hana wikiwiki, kiʻekiʻe ka pono, 'akomi manipulation, a hiki ke hoʻopololei i nā'āpana paʻakikī, kūpono loa no ka hana nui. ʻO ka hemahema, he kiʻekiʻe ke kumukūʻai o nā mea hana a me ka mold, a me ka injection. paʻakikī ka hoʻomaʻemaʻe ʻana i ka mīkini hana.

⑷ hoʻoheheʻe ʻia: hollow blow a i ʻole hollow molding. ʻO ka hoʻoheheʻe ʻana he ala ia o ka puhi ʻana i nā huahana hollow ma ke kaomi ʻana o ka ea i hoʻopaʻa ʻia e pani ʻia ka billet resin wela i loko o ka mold.Hoʻokomo ʻia ka hoʻoheheʻe ʻana i nā ʻano ʻelua o ka puhi ʻana i ke kiʻiʻoniʻoni a me ka puhi ʻana i nā huahana hollow.

⑸ Kalendering: He ʻano hana ia e hana ʻia ai ka resin a me nā mea hoʻohui like ʻole (kneading, kānana, a me nā mea ʻē aʻe) i loko o nā kiʻiʻoniʻoni a i ʻole nā ​​​​pepa ma o nā āpau ma waena o ʻelua a ʻoi aku ka nui o nā wili calendering o ka calender, a laila e ʻili ana i ka wili o ka kalena. ka calender, a laila hana ʻia e ka cooling.Calendering ka mea nui i hoʻohana ʻia i ka polyvinyl chloride resin molding method, hiki ke hana i ke kiʻiʻoniʻoni, ka pepa, ka pā, ka ʻili artificial, nā tile papahele a me nā huahana ʻē aʻe.

Yantai Dongyuan Plastic Products Co.. ʻO ka ʻupena huki lima lima, ʻupena palekana, hoʻohana nui ʻia i loko o ke awa, nā ʻoihana hoʻomeamea kemika, ka palaoa a me ka ʻaila hana ʻoihana o ka mālama ʻana i ka meaʻai soybean a me ka halihali. a me ka lawaia.
