Nā uhi manhole hao
Hāʻawi ʻo Mingda i nā lawelawe hoʻohuli pololei mai nā mīkini huli CNC hou loa.
Me ka ʻoi aku o 10 mau makahiki o ka ʻike ma nā lawelawe machining precision maʻamau, ua paʻa mākou e hāʻawi i nā huahana kiʻekiʻe me nā kumukūʻai hoʻokūkū.
Hiki iā mākou ke hāʻawi i nā ʻāpana mīkini kikoʻī CNC, nā ʻāpana huli ʻana o CNC, nā ʻāpana milling CNC, ka wili ʻana i ka ʻili, CNC engraving etc.
Hiki ke hana ʻia nā ʻāpana mai 1mm a 300mm i ka alumini, ke kila kila, ke kila kila, ke keleawe a me ka plastic (nylon, PMMA, teflon etc.).
A hiki iā mākou ke hana i ka hana lua a me ka hana sub-assembly no ʻoe ke hoʻopau ʻia ka prototyping CNC.
ʻOi aku ma mua o 10 mau makahiki o ka hoʻolālā ʻana a me ka hana ʻana i nā ʻano ʻāpana mīkini pololei.
ʻO CNC Precision Machining ʻāpana metala no nā mea kūʻai aku ma waho a ma ka home.
Hana kūikawā i ka hana ʻana i nā huahana a me nā ʻāpana me nā ʻae paʻa a me nā ʻano paʻakikī.
ʻO OEM Ductile hao one castings, nalowale foam casting, Vacum Molding a pēlā aku, e koho ʻia ka ʻoihana hana e like me ke noi hoʻomanawanui maoli a me ka nui koi.Hoʻohana ʻia ka hapa nui o kā mākou hoʻoheheʻe ʻana no nā valves, hydrants, pumps, trucks, railway and train and so on.
hōʻike huahana：
ʻO ka paʻakikī maikaʻi. ʻO ka waiwai hopena e like me ke kila kalapona waena, ʻoi aku ia ma mua o 10 mau manawa o ka mea hao hina.
ʻO ke kūpaʻa ʻino ikaika. I ka hoʻāʻo ʻana i ka corrosion wai, ʻo ka nui o ka corrosion i nā lā 90 he 1/40 wale nō o ka paipu kila a me ka 1/10 o ka paipu hao hina. ʻO ke ola lawelawe he 2 mau manawa o ka paipu hao hina a me 5 manawa o ka paipu kila maʻamau.
ʻO ka plasticity maikaʻi. Elongation ≥7%, e like me ke kila kalapona kiʻekiʻe, akā ʻo ka elongation mea hao hina he zero.
ʻO ka ikaika kiʻekiʻe.ʻO ka ikaika tensile ob ≥420MPa a me ka hoʻouluʻana i ka ikaika OS ≥300MPa e like me ke kila kalapona haʻahaʻa aʻekolu manawa e like me ka mea hao hina.
Ma muli o kāna microstructure graphite nodular, ʻoi aku ka maikaʻi o ka hao ductile ma mua o ka hoʻolei ʻana i ke kila i ka hōʻemi ʻana i ka mana vibration, no laila ʻoi aku ka maikaʻi o ka hoʻemi ʻana i ke kaumaha. ʻOi aku ka maikaʻi o kēia mea hao, ʻoi aku ka maikaʻi, a emi ke kumu kūʻai i ka mīkini.
ʻO ka ikaika o ka hao ductile e hoʻohālikelikeʻia me ke kila. ʻO ka hapa nui o nā noi municipal e like me ka wai, ka wai paʻakai, ka mahu, etc.
hoʻolauna ʻoihana：
He ʻoihana kalepa ʻo Hebei Mingda International Trading Company i loea i nā castings, forgings a me nā ʻāpana mīkini.
ʻO kā mākou huahana nā ʻano mea hoʻoheheʻe maka e hana ʻia me ka hao ductile, hao hina, keleawe, stainlesssteel a me nā alumini,
nā ʻāpana hoʻoheheʻe ʻia a me nā ʻāpana i hana ʻia.No ka hana ʻana i kēia mau ʻāpana e like me nā kiʻi o nā mea kūʻai aku,
Loaʻa iā mākou nā mea hana hana kūpono a me nā mea hana, e like me ke one resin, ke one mold, nā pahu wela wela, nalowale-wax, nalowale ka ʻūhā a pēlā aku.
No nā kino hydrant a me nā kino valves, ua hōʻiliʻili mākou i ka ʻike waiwai no kēia mau huahana i ka hana maoli o 16 makahiki i hala,
I kēia manawa, haʻaheo mākou i kā mākou huahana me ka ʻili maikaʻi a me nā mea kiʻekiʻe.ʻO nā mea a pau, ua hoʻāʻo mākou i kā mākou mea maikaʻi loa e hāʻawi i kā mākou mea kūʻai aku me ka maikaʻi ʻoi aku ka maikaʻi
nā hoʻolei ʻana ma o ka hoʻomaikaʻi ʻana i nā hana hana a me ka mālama pono ʻana i ka maikaʻi.
Ke kali nei i ka loaʻa ʻana o kāu ʻano pane maikaʻi loa i kāu mua loa!
