Hoʻomaʻamaʻa i ka māka kamaʻilio ma ka Injection Molding

He hemahema maʻamau ma kahi kokoke i ka ʻīpuka i loko o nā hemahema hoʻoheheʻe ʻia.Eia naʻe, huikau ka poʻe he nui, ʻaʻole hiki iā lākou ke ʻike i ka hemahema a i ʻole ke kuhi hewa ʻana.I kēia lā, e wehewehe mākou.
Hōʻike ʻia ʻo ia e nā māwae e ʻā ana mai ka ʻīpuka a hiki i ka ʻaoʻao, he hohonu a he ʻalohilohi.Eia kekahi, ʻaʻole ia ka māwae, akā ʻo ke kumu o ka māwae ka anisotropy o ka mea paʻa.
I ka wā o ka hoʻokomo ʻana i ke kāpili ma ka ʻīpuka waena, ʻoi aku ka nui o ka ikaika kahe o ka longitudinal (ikaika tensile) o ka mea, ʻoiai ka liʻiliʻi o ka ikaika kahe transverse (ikaika tensile).ʻO ke koʻikoʻi i hana ʻia e ka shrinkage e huki i ka huahana a haʻihaʻi, a pono e hoʻomaka ka haʻihaʻi ma kahi nāwaliwali loa, ʻo ia hoʻi, ka ʻāpana transverse o ka mea kokoke i ka ʻīpuka me ke koʻikoʻi kūloko nui loa.

ʻO ka hemahema ʻo ka māwae kahi kīnā koʻikoʻi loa, ʻaʻole hiki ke hele, no laila pono e hoʻoponopono ʻia.Penei ka manao:
1. E pili ana i na mea
ʻO ka rigidity o ka mea ke kumu nui o nā hōʻailona kamaʻilio, no laila ke lōʻihi ke kaʻina o nā huahana nui, e ho'āʻo e koho i nā mea paʻa loa a loaʻa ka elongation haʻahaʻa i ka wā haki, e like me GPPS, AS, etc.
I nā mea maʻamau, ʻo ke ʻano o ka rigidity mai ka nāwaliwali a hiki i ka ikaika, a ʻo ka hiki ʻana mai o ka māwae seismic mai ka liʻiliʻi a i ka nui e pili ana: PE => TPU => PP => PC =>ABS=>PA=>PVC=>PET=>POM=>PMMA=>AS=>PS.
Ma keʻano laulā, hiki i nā mea me nā hui maʻalahi ke hoʻomaikaʻi i ke ʻano vibration.No ka laʻana, pono nā mea hao, SEBS, EVA, K.
2. E pili ana i ka poni
ʻO ka hoʻolālā puka o kahoʻoheheʻe ʻiaʻo ia ke kī.ʻO ka ʻōlelo maʻamau, ma lalo o ka hale me ke koʻikoʻi kūloko nui a me ke kahe kaʻina hana lōʻihi, maʻalahi ke ʻano o ka haʻalulu ʻīpuka.No laila, no nā huahana nui, maʻalahi ka hoʻohana ʻana i ke ʻano o nā ʻīpuka he nui a me nā puka ākea e hōʻemi i ke kūpaʻa hānai ʻana a hoʻomaʻamaʻa i ke kahe.
Ma ka ʻōlelo maʻamau, maʻalahi ka puka kiko ke ʻike i nā laina haʻalulu.ʻO ka ʻīpuka ʻaoʻao, ka ʻīpuka peʻa a me ka ʻīpuka uha he haʻahaʻa iki.Akā ʻaʻole e hoʻohana ʻia nā ʻīpuka ʻē aʻe, e like me ka puka submersible a me ka puka diaphragm i loko o ia mau hale.No ka mea, ʻo ka hapa nui o nā huahana me nā laina vibration he mau huahana akaka, ʻaʻohe pono e hoʻohana i nā awa luʻu a i ʻole nā ​​awa diaphragm.
3. E pili ana i nā ʻāpana: ʻo ke ana o nā ʻāpana e hoʻonā i nā kaha kamaʻilio:
①Me ka wikiwiki o ka pana ʻana a me ke kaomi haʻahaʻa
②Piki ke kaomi manawa paʻa
③Pono ke kiʻekiʻe ka wela o ka mold, e like me ka mea PS.Hiki ke hoʻonohonoho ʻia ka mahana mold i 60 degere.
4. Hōʻuluʻulu manaʻo
ʻO ka Shattering kahi hemahema maʻamau i ka hana ʻana i nā huahana alohilohi i hana ʻia me nā mea GPPS.Inā ʻaʻole mākou e hoʻolohe i nā ʻano hana lapaʻau, ʻoi aku ma mua o 50% o nā hemahema a i ʻole nā ​​​​mea āpau.Ma ka haku ʻana i nā ʻano hana i luna aʻe e hiki ai iā mākou ke hoʻopau i nā hemahema a hōʻoia i ka hana paʻa a kiʻekiʻe.
