He aha ka hoʻoheheʻe ʻana i ka inikini:ʻO ke kaʻina hana hoʻoheheʻe ʻana he hana ia o ka hana ʻana i nā ʻāpana semi-hoʻopau ʻia o kahi ʻano kikoʻī mai nā mea maka i hoʻoheheʻe ʻia ma o nā hana e like me ke kaomi ʻana, ka hoʻokomo ʻana, ka hoʻomaʻalili ʻana, ka wehe ʻana i ka ʻōpala, a me ka hoʻokuʻu ʻana i ka ʻōpala. ʻO kāna mau mea maka he ABS\PE polyethylene, PP polypropylene, PA, polystyrene a pēlā aku.

Kumumanaʻo o ke kaʻina hana hoʻoheheʻe injection:E hoʻohui ʻia nā mea maka granular a pauka paha i ka silo o ka mīkini hoʻoheheʻe injection, ʻo ka mea maka i ke ʻano wai ma o ka hoʻomehana ʻana a me ka hoʻoheheʻe ʻana, i loko o ka mīkini hoʻoheheʻe injection screw a i ʻole ke koʻokoʻo piston e hoʻolaha i ka mīkini hoʻoheheʻe injection, ma o ka nozzle a me ka ʻōnaehana hoʻolei ʻōpala make-casting i loko o ka ʻōmole concave mold, ka ʻōmole concave mold i loko o ka ʻōmole paʻakikī a me ke ʻano.

ʻO ka noi:Hiki ke hoʻopili ʻia nā huahana i hoʻoheheʻe ʻia i nā ʻoihana he nui, ʻo ka hapa nui o nā huahana plastik ma ka mākeke i loaʻa mai ke kaʻina hana hoʻoheheʻe ʻana, e like me nā mea pāʻani plastik, ka uhi hope o kāu kamepiula home TV, ka mea hoʻomaʻemaʻe ea, nā ʻōpala ʻōpala, nā pūpū robots akamai, a pēlā aku, e like me ka ʻike ʻana o ka maka, he nui nā ʻāpana plastik i loaʻa mai ke kaʻina hana hoʻoheheʻe ʻana i waho o ka huahana.

Nā pono:① wikiwiki ka hana ʻana, kiʻekiʻe ka pono. ②hiki ke hana ʻakomi ʻia ka hana. ③ʻano kala. ④hiki ke ʻano mai ka maʻalahi a i ka paʻakikī. ⑤hiki ke nui mai ka nui a i ka liʻiliʻi, a pololei ka nui o ka huahana. ⑥He maʻalahi ka hoʻonui ʻana i nā huahana. ⑦hiki ke lilo i ʻano paʻakikī o nā ʻāpana, kūpono no ka hana nui a me ke ʻano o nā huahana paʻakikī a me nā wahi hana hoʻoheheʻe ʻē aʻe.

Nā mea maka plastik i hoʻohana pinepine ʻia no ka hoʻoheheʻe ʻana i ka injection: ABS, PP, PVC, PC. Nā mea i hoʻohana pinepine ʻia no ka mold:45 #, P20, 718, 738, S136.

ʻO ka ʻokoʻa ma waena o ka mea PP a me ka mea ABS:He ʻokoʻa nā waiwai a me nā hoʻohana o nā mea ʻelua. Hana mea ABS: hana holoʻokoʻa ʻoi aku ka maikaʻi, ikaika hopena kiʻekiʻe, kūpaʻa kemika maikaʻi, nā waiwai uila maikaʻi. Hoʻohui maikaʻi me372ʻO ke aniani organik, i hana ʻia me nā ʻāpana plastik ʻelua kala, hiki ke uhi ʻia me ka chrome ma luna, pena ʻia. ʻO ka hopena kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka lapalapa, hoʻonui ʻia, ʻike ʻia a me nā ʻano ʻē aʻe. Nā waiwai o ka mea PP: he mea crystalline, he liʻiliʻi ka hygroscopicity, maʻalahi ke hoʻoheheʻe i ka haki kino, maʻalahi ka decompose i ka pilina lōʻihi me ka metala wela. He maikaʻi ka neʻe ʻana, akā he nui ka laulā shrinkage a me ka waiwai shrinkage, maʻalahi ka shrinkage dent, deformation phenomenon.
