chitsulo champhamvu cha kaboni champhamvu kwambiri chawiri chopangidwa ndi stud bolt

Stud, yomwe imadziwikanso kuti zomangira ziwiri kapena ma stud. Yogwiritsidwa ntchito pa ntchito yolumikizira makina olumikizira, ma bolt awiri amakhala ndi ulusi mbali zonse ziwiri, ndipo screw yapakati imapezeka mu kukula kokhuthala komanso kowonda. Nthawi zambiri imagwiritsidwa ntchito mumakina amigodi, milatho, magalimoto, njinga zamoto, nyumba zachitsulo za boiler, nsanja zoyimitsidwa, nyumba zachitsulo zazikulu, ndi nyumba zazikulu.

Boluti imatanthauza makamaka sikulufu yokhala ndi mainchesi akulu, yomwe singakhale ndi mutu, monga boluti yokhala ndi mitu iwiri. Kawirikawiri, simatchedwa "boluti yokhala ndi mitu iwiri" koma m'malo mwake "boluti yokhala ndi mitu iwiri". Mtundu wofala kwambiri wa ma stud okhala ndi mitu iwiri ndi ulusi kumapeto onse awiri ndi ndodo yosalala pakati.

Maboti okhala ndi mitu iwiri nthawi zambiri amafunikira chithandizo cha pamwamba, ndipo pali mitundu yambiri ya chithandizo cha pamwamba pa maboti, kuphatikizapo electroplating, blackening, oxidation, phosphating, ndi chithandizo cha nonelectrolytic zinc sheet coating. Komabe, ma electroplating fasteners ndi omwe amagwiritsidwa ntchito kwambiri pakugwiritsa ntchito ma fasteners. Makamaka amagwiritsidwa ntchito kwambiri m'mafakitale ndi m'magawo monga magalimoto, mathirakitala, zida zapakhomo, zida, ndege, kulumikizana, ndi zina zotero.

Komabe, pa zomangira zokhala ndi ulusi, sikofunikira kokha kukhala ndi mphamvu yolimbana ndi dzimbiri panthawi yogwiritsa ntchito, komanso kuonetsetsa kuti ulusiwo umasinthana, zomwe zingatchulidwe kuti screwability pano. Kuti nthawi imodzi mukwaniritse zofunikira ziwiri za "anti-corrosion" ndi "interchangeability" za zomangira zokhala ndi ulusi zomwe zikugwiritsidwa ntchito, ndikofunikira kupanga miyezo yapadera ya electroplating layer.

Dongguan Yuhuang Electronic Technology Co., Ltd. idakhazikitsidwa mu 1998, makamaka yodzipereka pa kafukufuku, chitukuko, kusintha, ndi kupanga zomangira zosakhazikika. Kampaniyo ili ndi maziko awiri opangira, Dongguan Yuhuang yokhala ndi malo okwana masikweya mita 8000 ndi Lechang Science and Technology Park yokhala ndi malo okwana masikweya mita 12000. Tadutsa ziphaso za ISO9001, ISO14001, ndi IATF16949, ndipo zinthu zonse zimagwirizana ndi miyezo ya REACH ndi ROHS.

Makasitomala athu ogwirizana ali m'maiko opitilira 40 padziko lonse lapansi, kuphatikiza makampani odziwika bwino am'deralo monga Huawei, Hisense, ndi Xiaomi, komanso makampani akunja monga BOSSARD, KUS, ndi FASTENAL. Zogulitsa zathu zimagwiritsidwa ntchito kwambiri mu makamera achitetezo, zamagetsi, zida zamagalimoto, ndege, kulumikizana kwa 5G, makamera amafakitale, zida zapakhomo, zida zamasewera, ndi mafakitale azachipatala.
