Huahana Huahana

hoʻolauna i nā huahana:

ʻO Brass Copper DIN7991/931/933 Bolts nā ʻano ʻelua: DIN7991 (CSK flat - head with internal hex socket) no ka flush - fitting installations, a me DIN931/933 (hex head with partial/full threading) no ka ukana - pili pili. Hana ʻia mai ke keleawe/keleawe, hāʻawi lākou i ke kūpaʻa ʻino kūlohelohe, ka conductivity uila maikaʻi loa, a me ka hoʻopau gula nani. ʻO ke poʻo countersunk DIN7991 e hōʻoia i kahi snag - manuahi ʻole; Loaʻa iā DIN931 nā lola ʻāpana (kūpono no nā mea hana mānoanoa), ʻoiai ʻo DIN933 e hōʻike ana i nā kaula piha (kūpono no nā - puka). Loaʻa i nā nui mai M2 a M24, hoʻohana nui ʻia lākou i nā lako (decorative fastening), nā lako uila (conductive joints), architectural hardware (ornamental mounts), a me nā mea hana pololei (low - profile fixing), balancing aesthetics and functionality.

Nā kuhikuhi no ka hoʻohana ʻana:

DIN7991: E hoʻouka me ka hoʻohana ʻana i kahi wīwī hex kūloko like ʻole, e hoʻopaʻa ʻia a hiki i ka piha ʻana o ke poʻo CSK me ka mea hana (e pale i ka hoʻopaʻa ʻana i mea e pale ai i ke kaua ʻana o nā mea).

DIN931/933: E hoʻohana i kahi wīwī hex waho, e hahai ana i nā kuhikuhi torque i ʻōlelo ʻia (e hoʻomaopopo he haʻahaʻa ka ikaika o ke keleawe ma mua o ke kila, no laila e pale i ka ikaika nui).
No ka mālama ʻana: E hoʻomaʻemaʻe mau i nā bolts me kahi lole maloʻo. Hoʻokumu maoli ke keleawe i kahi patina i ka manawa; inā makemake ʻia ka polishing, e hoʻohana i ke keleawe - nā mea hoʻomaʻemaʻe kikoʻī. Hōʻalo i ka ʻike lōʻihi i nā ʻakika ikaika a i ʻole nā alkali no ka mālama ʻana i ka hopena.

Hebei Duojia Metal Products Co., Ltd. ua ʻike mua ʻia ʻo Yonghong Expansion Screw Factory. Loaʻa iā ia ma mua o 25 mau makahiki o ka ʻike loea i ka hana ʻana i nā mea hoʻopili. Aia ka hale hana ma ka China Standard Room Industrial Base - Yongnan District, Handan City. Ke alakaʻi nei ia i ka hana pūnaewele a me waho a me ka hana ʻana i nā mea hoʻopaʻa a me ka ʻoihana lawelawe kūʻai hoʻokahi.

Hoʻopili ka hale hana i kahi ʻāpana o 5,000 square meters, a ʻo ka hale kūʻai e uhi ana i kahi o 2,000 square meters. I ka makahiki 2022, ua hoʻokō ka hui i ka hoʻomaikaʻi ʻana i ka ʻoihana, hoʻoponopono i ka ʻōnaehana hana o ka hale hana, hoʻomaikaʻi i ka hiki ke mālama, hoʻonui i ka hiki ke hana palekana, a hoʻokō i nā hana palekana kaiapuni. Ua hoʻokō ka hale hana i kahi ʻōmaʻomaʻo mua a me ke kaiapuni.

Loaʻa i ka hui nā mīkini paʻi anu, nā mīkini paʻi, nā mīkini paʻi, nā mīkini threading, nā mīkini hana, nā mīkini puna, nā mīkini crimping, a me nā robots welding. ʻO kāna mau huahana koʻikoʻi he ʻano o ka hoʻonui ʻia ʻana i kapa ʻia ʻo "wall climbers".

Hoʻopuka pū ʻo ia i nā huahana makau ʻano ʻano kūikawā e like me ka lāʻau uʻi niho lāʻau wiliwili maka hipa wili a me ka mīkini niho hipa maka apo bolts. Eia hou, ua hoʻonui ka hui i nāʻano huahana hou mai ka hopena o 2024. Ke nānā neiʻo ia i nā huahana i kanu muaʻia no kaʻoihana kūkulu.

Loaʻa i ka hui kahi hui kūʻai ʻoihana a me kahi hui hahai ʻoihana e mālama i kāu huahana. Hoʻopaʻa ka hui i ka maikaʻi o nā huahana āna e hāʻawi ai a hiki ke hana i ka nānā ʻana i nā māka. Inā loaʻa kekahi pilikia, hiki i ka hui ke hāʻawi i ka lawelawe ma hope o ke kūʻai aku.

ʻO kā mākou mau ʻāina e hoʻokuʻu aku ai me Russia, South Korea, Britain, France, Germany, Italy, Canada, Mexico, Brazil, Argentina, Chile, Australia, Indonesia, Thailand, Singapore, Saudi Arabia, Syria, Egypt, Tanzania.Kenya a me nā ʻāina ʻē aʻe. E hoʻolaha ʻia kā mākou huahana a puni ka honua!

No ke aha e koho ai iā mākou?

1. Ma keʻano he mea hoʻokiʻekiʻe kiʻekiʻe o ka hale hana, hoʻopau mākou i nā palena waena e hāʻawi iāʻoe i ka uku hoʻokūkū no nā mea hoʻopaʻa kiʻekiʻe.
2. kā mākou hale hana i ka ISO 9001 a me ka AAA hōʻoia .ua loaʻa iā mākou ka ho'āʻo paʻakikī a me ka ho'āʻoʻana i ka mānoanoa o ka zinc coating no nā huahana galvanized.
3. me ka mana piha ma luna o ka hana a me ka logistic, ke hōʻoiaʻiʻo nei mākou i ka lawe ʻana i ka manawa no nā kauoha wikiwiki.
4. ʻO kā mākou hui ʻenekinia hiki ke hana i nā faseners mai ka prototype a i ka hana nui, me nā hoʻolālā wili kūikawā a me nā pale anti-corrosion.
5.From carbon steel hex bolts a kiʻekiʻe-tensile heleuma bolts, hāʻawi mākou i kahi hopena hoʻokahi no kāu mau mea paʻa a pau.
6. Inā loaʻa kekahi hemahema, e hoʻouna hou mākou i nā pani i loko o 3weeks o kā mākou kumukūʻai.
