ʻO ka hoʻoheheʻe injection kahi kaʻina hana mua a me ka ʻenehana kumu koʻikoʻi i ka hoʻoili ʻana i nā plastics ʻoihana. Me kēia ʻenehana hana ʻenehana, hiki ke hana ʻia nā huahana plastik kikoʻī o ka mea kūʻai aku me ke kumu kūʻai mai kahi malleable plastic mass, kahi kiʻekiʻe o ka reproducibility me ka nānā ʻole i ke ʻano.

pehea ka hana ʻana o ka hoʻoheheʻe ʻana

ʻO ke kaʻina hana i loko o ka hoʻoheheʻe ʻana i hana ʻia i ka cyclically i hoʻokahi hana me kahi pōʻai hana i hoʻonohonoho pono ʻia, hoʻokaʻawale ʻia i ka dosing a me ka plasticizing, injection a me ka paʻa ʻana i ke kaomi a me ka hoʻoluʻu a me ka ejection. Hoʻokomo ʻia kahi ʻilika malleable i loko o ka lua o kahi ʻāpana kūpono kūpono a hoʻokuʻu ʻia ma ke ʻano he ʻāpana i hoʻopau ʻia.

1. Hoʻopaʻa ʻia / Plasticizing

Ke hele nei nā granules plastik i hoʻopaʻa ʻia i loko o kahi pahu i loko o nā ʻōkuhi spiral o kahi wili kaʻa, kahi i hoʻoheheʻe ʻia e ka wela o ka cylinder a me ka wela frictional.

2. Injection / Repressurization

Hoʻokomo ʻia ka nui o ka wai i loko o ka mold injection ma o ke kahawai sprue ma ke kaomi kiʻekiʻe o 2000 bar. ʻO ke kaomi ʻana i ka nuipa hou e hoʻokō i ka emi ʻana o ka hoʻoilo.

3. Hooluu iho / Hookuke

I ka paʻa ʻana o ka sprue, pani ʻia ka nozzle injection. Hoʻihoʻi ʻia ka cylinder plasticizing a hoʻokuʻu ʻia ka ʻāpana i hoʻopau ʻia i hoʻopau ʻia ma hope o ka hoʻoilo.

He aha nā kaʻina hana hoʻoheheʻe ʻia?

Hoʻokaʻawale ʻia ke kaʻina hana hoʻoheheʻe i thermoplastic, ʻO ke kaʻina o ka waiwai waiwai nui ʻo ka thermoplastic injection molding. Eia kekahi, hoʻohanaʻia nāʻenehana kūikawā, e like me hoʻokomo hoʻoheheʻe a i ʻole ka hoʻoheheʻe ʻana o ka silicone wai.

ʻO ka hoʻoheheʻe ʻia ʻana o Thermoplastic

ʻO ka hoʻoheheʻe ʻana o Thermoplastic ka hana maʻamau no ka hana wikiwiki ʻana o nā ʻāpana me nā geometries paʻakikī, ka pololei kiʻekiʻe, a me nā puke kiʻekiʻe.

Ma kēia kaʻina hana, hoʻokomo ʻia nā thermoplastics e like me ka polyamide, polycarbonate, a i ʻole polyethylene i loko o nā mole metala. Hiki ke hana ʻia kēia mau metala me ka alumini no ka hana ʻana i nā prototypes, a i ʻole ke kila no nā pūʻulu liʻiliʻi. Loaʻa i nā mea hana alumini a me nā mea kila ko lākou pono, a hauʻoli ka poʻe loea molding injection ma TEAM Rapid e hoʻolālā a hana. ʻūhā nui ʻulaʻula e like me kāu mea injection a me nā koi hoʻopuka.

Ma waho aʻe o nā mea o ka mea paahana, hiki ke hoʻokō maʻalahi ʻia e nā mīkini a me nā mea hana a ka hui wikiwiki, e like me ka texturing, engraving, a i ʻole nā ​​hiʻohiʻona kikoʻī.

Loaʻa i ka TEAM wikiwiki nā ʻano plastics e koho mai no ka hana ʻana i kāu mau ʻāpana. ʻO kekahi mau hiʻohiʻona o kēia ʻo ABS, PA, PC, PET, PE, PLA, PMMA, PS, PP PEEK, PVC, co-blends, a me nā thermoplastics ʻē aʻe. Hiki nō hoʻi ke hoʻoikaika ma ka hoʻohana ʻana i nā fiber aniani, nā pahu aniani, nā minela, a i ʻole nā ​​​​mea hoʻohui ʻē aʻe.

Hoʻoheheʻe Thermoset Injection

Ua hōʻoia ʻo Thermosetting plastics i ko lākou waiwai i ka hoʻoheheʻe ʻia ʻana no nā ʻāpana plastik i hoʻoheheʻe ʻia i hiki ke kūpaʻa i nā ukana mechanical a ʻaʻole heheʻe a ʻāwili koke i nā mahana ma waena o 30 a ʻoi aku ma mua o 100 degere.

ʻO nā panhandles, nā uhi kukui, a ma luna o nā hale o nā mea uila he nui i hoʻoheheʻe ʻia mai nā plastic thermosetting. He ikaika loa ia ma hope o ka hana ʻana a hiki ke hana hou ʻia kēia plastik i kona ʻano hope loa ma hope o ka hana ʻana. ʻO ka ʻeli ʻana, ʻili ʻana a wili paha, a me nā mea hou aʻe e hiki ke hana me ka thermoset processing. Eia nō naʻe, pono e hoʻokō ʻia ka hoʻolālā ʻana o nā ʻāpana thermoset a hoʻopau ʻia ma hope o ka hoʻoiho mua ʻana. I ka wā e paʻakikī ai, ʻaʻole hiki ke hoʻololi hou ʻia ka plastic e like me ka thermoplastic akā e wāwahi ʻia inā piʻi ka wela. No kona paʻakikī a pau, ʻoi aku ka maʻalahi o nā plastik thermosetting i nā hopena ʻoi aku ma mua o ka thermoplastic, hiki ke haki.

Pehea ka hana ʻana o ka hoʻoheheʻe ʻana i ka thermoset?

Ma muli o nā waiwai o ka hoʻolālā ʻekolu-dimensional o nā kaulahao molekala o Thermosetting plastics, ua hoʻoheheʻe ʻia kēia ʻano plastic e like me ka trickle ma kahi haʻahaʻa haʻahaʻa mai 30 degere Celsius a paʻa hou i 130 degere Celsius. Hoʻokomo ʻia nā plastic thermosetting ʻaʻohe wai i loko o ka mea hana wela ma ke kaomi kiʻekiʻe o 2500 bar. Ma hope o ka paʻa ʻana, ʻaʻole hiki ke hoʻoheheʻe hou ʻia ka thermoset.

Hoʻokahuli

me ko kakou overmolding i nā kaʻina hana wikiwiki, hiki ke hana ʻia nā prototypes haʻahaʻa haʻahaʻa a me nā ʻāpana hana noiʻi i loko o 15 mau lā. ʻO kā mākou hoʻohana ʻana i nā mold alumini e hāʻawi i ka pono o nā kumukūʻai haʻahaʻa haʻahaʻa a hiki i nā ʻāpana ke hana ʻia me ka hoʻohana ʻana i nā ʻano thermoplastic a me nā mea silicone wai.

Hana ʻia nā ʻāpana i hoʻoheheʻe ʻia me ka hoʻohana ʻana i ke kaʻina hana hoʻoheheʻe maʻamau me ka ʻole o ka hoʻomehana a me nā laina hoʻoluʻu i loko o ka pahu alumini. ʻO ka manawa pōkole ʻoi aku ka lōʻihi e hiki ai i kā mākou casters ke nānā i nā kaomi injection, nā pilikia cosmetic, a me ka maikaʻi o ka ʻāpana kumu.

Ke hoʻoheheʻe ʻia ka pahu holoʻokoʻa, kau ʻia ka mea paʻi injection ma luna o ka paʻi. Hoʻokomo ʻia nā ʻāpana i hana mua ʻia e ka lima i loko o ka mold, kahi i hoʻoheheʻe ʻia kēlā me kēia ʻāpana me nā mea thermoplastic a i ʻole silicone wai.

Hoʻoheheʻe ʻia ʻo Liquid Silicone Rubber (LSR).

I kēia lā, ʻo ka hoʻoheheʻe injection kekahi o nā ala koʻikoʻi o ka hoʻoili ʻana i nā pūhui silicone rubber i ka hana ʻana o nā huahana he nui a me nā koi kiʻekiʻe i ko lākou kūpaʻa maikaʻi.

ʻO nā pono o ka Liquid Silicone Rubber (LSR) Injection Molding

Hōʻike ʻia ka hoʻoheheʻe ʻana i ka hoʻoheheʻe ʻia e ka pololei mold kiʻekiʻe. ʻO ka automation piha o ke kaʻina hana e hōʻoiaʻiʻo i nā mea kiʻekiʻe kiʻekiʻe ʻaʻole koi i ka hoʻoponopono hou ʻana, a me ka hōʻemi nui ʻana i nā pōʻai hana i hoʻohālikelike ʻia me nā ʻano hana ʻē aʻe. I ka manawa like, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o nā mold, nā mīkini, a me nā mea hana ma mua o nā ʻano ʻē aʻe. Eia naʻe, hoʻopau ʻia kēia e ka hana kiʻekiʻe o ka mīkini hoʻoheheʻe injection.

Ka hoʻohana ʻana i ka hoʻoheheʻe ʻia ʻana o ka Liquid Silicone Rubber (LSR).

ka pulupulu hoʻoheheʻe ʻia ʻoi aku ka maikaʻi o ke ala no nā huahana liʻiliʻi a me nā mea liʻiliʻi i hana ʻia i ka nui, e like me nā nipple omole pēpē, a me nā apo.

He aha nā mea i kūpono i ka hoʻoheheʻe ʻia ʻana?

Hoʻohana ʻia nā plastik āpau i hiki ke hoʻololi maʻalahi no ka hoʻoheheʻe ʻana. Hiki ke hana ʻia nā Thermoplastics, duroplastics, a me nā elastomers, me ka hoʻoheheʻe thermoplastic ʻo ia ke kaʻina hana me ka waiwai waiwai nui. ʻO nā laʻana maʻamau ʻo ABS, PC, PPA, POM, PP, a i ʻole PMMA plastics.

Nā pōmaikaʻi o ka hoʻoheheʻe ʻana

ʻO nā pōmaikaʻi o ka molding:

1. Kiʻekiʻe reproducibility o ka hana

2. ʻO ka liʻiliʻi a i ʻole ka hoʻoponopono hope ʻana o ka ʻāpana i hoʻoheheʻe ʻia he pono

3. Hiki ke hoʻohana ponoʻia ke kaʻina hana

ʻO ka lawelawe hoʻoheheʻe ʻia ʻana He kaʻina hana hoʻokele waiwai i hiki ke hana hou ʻia no ka mea hiki ke hana ʻia nā ʻāpana paʻakikī i ke kumu kūʻai i ka hana hoʻokahi a me ka ʻole o ka hoʻomaʻamaʻa ʻana i ka mīkini ma nā ʻāpana āpau. Hoʻohana maikaʻi loa ka ʻenehana, no ka mea hiki ke hoʻoheheʻe ʻia nā koena plastik a hoʻohana hou ʻia no nā papahana hou. E kelepona mai iā mākou i kēia lā no kāu mau papahana i kēia manawa!
