He aha ka hoʻolei ʻana i ka vacuum?
ʻO kaʻenehana hoʻoheheʻe ʻiahoʻohana nui ʻia no ka hana prototype liʻiliʻi ma muli o kona manawa pōkole a me ke kumu kūʻai haʻahaʻa.ʻO ka nui o nā noi no nā ʻāpana Vacuum Casting he nui nō hoʻi, me ka automotive a me ka aerospace, pharmaceutical and medical, telecommunications and engineering, i ka meaʻai a me nā mea kūʻai aku. ʻO ABS, polycarbonate, polypropylene, ke aniani hoʻopiha nylon, a me ka elastomer rubber.
ABS
Ua kaulana ʻo Acrylonitrile butadiene styrene ma muli o kona kumu kūʻai haʻahaʻa
PP
ʻO ka polypropylene kekahi o nā plastics i hoʻohana nui ʻia a maʻalahi loa e hoʻoheheʻe ʻia.
ANIANI PIHA MEA
Hoʻonui nā polymers i piha i ke aniani i ka ikaika o ke kūkulu ʻana, ka ikaika hopena, a me ka rigidity.
PC
Hāʻawi ka Polycarbonate i ke kūpaʻa hopena kiʻekiʻe a loaʻa i nā ʻano like ʻole.
RUPA
ʻO nā mea e like me ka Rubber he paʻakikī a maikaʻi ka ikaika o ka waimaka.He kūpono lākou no nā gaskets a me nā sila.
NA WAIWAI HOOLE WAIWAI
Pehea ka hana ʻana o ke kaʻina hoʻoheheʻe ʻana?E nānā kākou ma lalo:
1. Ma mua o ka hana ʻana i ka mold silicone, pono mākou e hana i kahi laʻana e like me nā kiʻi 3d a ka mea kūʻai aku.Hana ʻia ka laʻana e ka paʻi 3D a i ʻole CNC machining.
2. A laila e hoʻomaka i ka hana ʻana i ka mold silicone, pono e hui maikaʻi ʻia ke silicone a me ka mea hoʻōla.ʻO ka hiʻohiʻona o ka mold silicone he wai kahe, ʻo kahi mea he silicone, a ʻo ka mea B he mea hoʻōla.Ma hope o ka hui maikaʻi ʻana o ka silicone a me ka curing agent, pono mākou e haʻalele i nā ʻōpū ea.ʻAʻole pono ka manawa o ka hoʻoheheʻe ʻana ma mua o 10 mau minuke, i ʻole, e hoʻōla koke ʻia ke silicone.
3. Ma hope o ia mea, hoʻopiha mākou i ka mold me ka resin a waiho i loko o ke keʻena vacuum e hōʻoia i ka loaʻa ʻole o nā ea i loko o ka pahu.ʻO kēia ka mea e hōʻoia ai ʻaʻole i hōʻino ʻia ka huahana hope.
4. Hoʻokomo ʻia ka resin i ka umu no ka pae hoʻōla hope.Hoʻopau ʻia ka ʻāpana i hoʻopau ʻia ma hope o ka hoʻomaʻemaʻe ʻana, hiki ke hoʻohana hou ʻia no ka pōʻai hana hou.ʻO ka mea maʻamau, hiki i kahi mold silicone ke hana i 10-20 pcs samples.
ʻO ka mea hope loa, hiki ke hoʻonani ʻia a pena ʻia nā prototypes i kēlā me kēia kala e like me nā koi o ka mea kūʻai aku.
Inā ʻoe e ʻimi nei i kahi prototype hoʻoheheʻe vacuum a makemake paha i ka ʻōlelo aʻoaʻo ʻoihana e pili ana i nā mea kūpono e hoʻokō ai i nā waiwai āu e pono ai, hauʻoli mākou e hāʻawi i ka ʻōlelo aʻoaʻo a me ke alakaʻi i kēlā me kēia kūlana no kekahi koi prototyping.
