Nā huahana nui o Ningbo Zhongli Bolts Manufacturing Co., Ltd.

Ningbo Zhongli Bolts Manufacturing Co., Ltd., Hoʻokumu ʻia i ka makahiki 2003, he mea hana koʻikoʻi o nā mea hoʻopaʻa ikaika kiʻekiʻe i hoʻokumu ʻia ma Zhejiang Province, Kina. Me kahi hale hana ma kahi o 10,000 mau mika square a me ka mana hana makahiki ma mua o 8,000 metric tons, ʻoi aku ka ʻoihana i ka hana ʻana i kahi ākea o nā mea hoʻopaʻa maʻamau a maʻamau, ʻo ia hoʻi nā hex bolts, structural bolts, a me nā mea hoʻopili kūikawā ʻole. Hoʻopili kā lākou huahana i nā kūlana honua e like me GB (Chinese National Standards), DIN (German Industrial Standards), ISO (International Organization for Standardization), a me ANSI / ASME (American Standards), e mālama ana i nā ʻoihana e like me ke kūkulu ʻana, automotive, mīkini, a me ka ikehu.

Hoʻokumu ʻia ka waihona huahana o ka hui i nā mea hoʻopaʻa hana kiʻekiʻe, ʻoi aku ka nui o DIN933 a me DIN931 hex head bolts, i ʻike nui ʻia no ko lākou hilinaʻi mechanical a me ka hoʻololi ʻana i nā kaiapuni koi. Aia ma lalo kahi kikoʻī kikoʻī o kēia mau huahana, me ka nānā ʻana i kā lākou mau ʻano 10.9-grade.

1. DIN933a me DIN931Hex Bolts:

ʻO DIN933 a me DIN931 nā bolts hex maʻamau Kelemania i ʻike ʻia e kā lākou hoʻonohonoho pae.

- DIN933: Hōʻike i kahi hoʻolālā piha piha, e hōʻoiaʻiʻo ana i ka hāʻawi ʻana i ke kaumaha ma waena o ka lōʻihi o ka bolt. He mea kūpono kēia no nā noi e koi ana i ka ikaika clamping kiʻekiʻe, e like me nā mīkini kaumaha a me nā hui kūkulu.

- DIN931 : Hoʻolālā ʻia me kahi ʻāpana ʻāpana (half-threaded), e hāʻawi ana i ka hui pū ʻana o nā ʻāpana wili a me unthreaded shank. ʻOi aku ka maikaʻi o kēia hoʻonohonoho ʻana no nā pilina hui kahi koʻikoʻi ka pale ʻana o ka shear a me ka pololei pololei, e like me nā chassis kaʻa a i ʻole nā ​​​​pūnaewele hydraulic.

Papa 10.9 :

ʻO ka inoa 10.9-grade e hōʻike ana i ka ikaika tensile kiʻekiʻe o 1,040 MPa a me ka ikaika hua o 940 MPa, i loaʻa ma o ka hoʻomaʻamaʻa wela kiʻekiʻe a me nā mea hao hao (e laʻa, SCM435 a i ʻole like). Loaʻa kēia mau bolts i nā kaʻina hana hoʻomalu maikaʻi, me ka hoʻāʻo ʻana i ka paʻakikī (39-44 HRC) a me ka mālama ʻana i ka ʻili e like me ka uhi ʻana o ka ʻeleʻele a i ʻole ka zinc plating e hoʻomaikaʻi ai i ka pale ʻana.

2. Kaʻina Hana Hana a me ka hōʻoia maikaʻi

Hoʻohana ʻo Ningbo Zhongli i nā ʻenehana hana hou e hōʻoia i ka pololei a me ka lōʻihi o kāna mau bolts:

- Cold Forging: Hoʻokumu nā mīkini poʻomanaʻo anu nui i ke kila kila i loko o nā kī me ka liʻiliʻi o nā mea waiwai, e hōʻoia ana i ka pololei o ke ana.

- Hoʻomaʻamaʻa Heat: Hoʻopaʻa ʻia ka hoʻopau ʻana a me nā kaʻina hana hoʻonaninani i ka microstructure o ke kila, e hoʻokō ai i nā waiwai mechanical 10.9-grade.

- Hoʻomaʻamaʻa Surface: Aia nā koho i ka galvanization, hot-dip galvanizing, a me nā uhi ʻeleʻele oxide, i hana ʻia e pale aku i nā mea kūlohelohe e like me ka makū a me ka hoʻolaha kemika.

Paʻa ka hui i ka ISO 9001: 2015 palapala hōʻoia a hoʻohana i nā lako hoʻāʻo kiʻekiʻe, e like me nā mea hōʻike tensile a me nā mea loiloi metallurgical, e hōʻoia i ka hoʻokō ʻana i nā kūlana honua.

3. Nā noi a me ka pili ʻoihana

ʻO 10.9-grade DIN933 a me DIN931 bolts he mea koʻikoʻi i nā noi koʻikoʻi kiʻekiʻe:

- Ke kūkulu ʻana a me nā ʻenehana: Hoʻohana ʻia i nā ʻāpana kila, nā alahaka, a me nā hui ʻenekini makani ma muli o ko lākou hiki ke amo.

- Kaʻa a me nā Mīkini: Koʻikoʻi no nā ʻāpana ʻenekini, nā ʻōnaehana hydraulic, a me nā mea kaumaha kahi e pono ai ke kūpaʻa haʻalulu.

- Energy and Petrochemicals : Hoʻokomo ʻia i loko o nā paipu aila a me nā kahua o waho, me ka hoʻohana ʻana i kā lākou pale pale pale.

4. Hoʻopilikino a hiki i ke ao holoʻokoʻa

Hāʻawi ʻo Ningbo Zhongli i nā lawelawe hana maʻamau no nā bolts maʻamau ʻole, me nā ana i hoʻohālikelike ʻia (nā anawaena mai M8 a M100, lōʻihi a hiki i 6,000 mm), nā ʻano o nā kaula (maikaʻi a i ʻole nā ​​​​mea koʻikoʻi), a me nā māka waiwai (e laʻa,B7 stud bolt, A325). Hoʻokuʻu ʻia kā lākou huahana i ʻEulopa, ʻAmelika ʻAmelika, ʻAsia Hikina Hema, a me ka Hikina Waena, i kākoʻo ʻia e ka hui pū ʻana me nā mea hoʻolaha honua a me kahi pūnaewele logistic ikaika.

Ka hopena:

Ke kū nei ʻo Ningbo Zhongli Bolt Manufacturing Co., Ltd. ma ke ʻano he alakaʻi i ka hana paʻa kiʻekiʻe, e hui pū ana i ka mana koʻikoʻi, nā ʻenehana hana kiʻekiʻe, a me kahi ala kūʻai aku. ʻO kā lākou DIN933 aDIN931 papa 10.9Hex bolts e hōʻike ana i ka maikaʻi o ka ʻenekinia, e hālāwai ana i nā koi koʻikoʻi o nā ʻoihana like ʻole o ka honua. No nā kikoʻī hou aku, e nānā i nā kumuwaiwai kūhelu o ka hui a i ʻole nā ​​​​hōʻikeʻike ʻoihana e like me ka Shanghai Fastener Professional Exhibition.
