Kodi mungagule kuti mabawuti a Black zinc okhala ndi hexagonal? 

Mukuyang'ana mabawuti akuda a zinc-plated hex, osati bawuti iliyonse yakuda. Mapeto ake - akuda, owoneka bwino, osachita dzimbiri - amandiuza kuti mwina muli mumakina, zomanga zakunja, kapena zitsulo zamamangidwe pomwe mawonekedwe ndi chitetezo zimafunikira. Msampha wamba? Anthu amasokoneza black oxide ndi black zinc plating. Black oxide kwenikweni ndi gawo la dzimbiri lolamulidwa, kukana kwa dzimbiri kochepa. Black zinki plating ndi zokutira zinki ndi wosanjikiza wakuda chromate kutembenuka pamwamba. Imateteza gawo lapansi, imapereka maola abwino opopera mchere. Ngati mukufufuza izi, muyenera kufotokozera momveka bwino, kapena mupeza zinthu zolakwika zikugwera padoko lanu.

Kuyambira ndi Zodziwikiratu: Ogulitsa Makampani & Ogawa

Anthu ambiri amalumphira ku McMaster-Carr, Grainger, kapena Fastenal. Kwa ma prototyping kapena magulu ang'onoang'ono, ndizabwino. Mudzalipira ndalama zambiri, koma mudzazipeza mawa. Nsomba? Zogulitsa zawo pazomaliza zinazake ngati zinki zakuda zitha kuchepetsedwa mumitundu yonse ndi magiredi. Ndafunikira M12 x 80mm, Grade 8.8, zinki zakuda, ndipo McMaster anali nazo mu "dongosolo lapadera" ndi nthawi yotsogolera ya masabata a 3. Sibwino pamene mzere wopanga ukudikira. Ogawa awa akupeza kuchokera kwa opanga okha, kotero mukuwonjezera wosanjikiza. Pazochulukirachulukira - titi, zidutswa 10,000 kupita m'mwamba - kupita molunjika kumayamba kupanga zotsika mtengo.

Akatswiri azitsulo ndi zomangira pa intaneti ndi gawo lina. Malo ngati Bolt Depot, Albany County Fasteners. Kusiyanasiyana kwabwinoko nthawi zina, ndipo nthawi zambiri amalemba zolemba zaukadaulo monga mtundu wa zokutira ndi makulidwe. Ndakhala ndi zokumana nazo zabwino, komanso zosagwirizana. Gulu limodzi linali ndi chromate yakuda yofanana, mbali zake zimawoneka ngati zotuwa. Kuyankha kwawo kunali kwabwino, kunawalowetsa, koma kunayambitsa kuchedwa kwa sabata ziwiri. Phunziro: ngakhale ndi ogawa "akatswiri", funsani ziphaso zokutira kapena gulu lachitsanzo choyamba. Musaganize.

Funso lenileni limakhala kuchuluka ndi kutsutsa. Kwa ntchito zosafunikira, wogawa ndiwothandiza. Kwa pulojekiti yokhazikika, kapena ngati ma bolts ndi gawo lazinthu zomwe mukupanga, zoperekera ziyenera kukhala zozama komanso zodalirika. Ndipamene kusaka kwanu kumachoka pa "komwe mungagule" kupita "ndani amapanga izi, ndipo amachira ndani?"

Kupita Chindunji: Njira Yopanga

Apa ndipamene mumalekanitsa wogula wamba kuchokera kwa katswiri wogula. Kupeza fakitale yeniyeni. China, mosadabwitsa, ili pachimake pakupanga ma fastener. Chigawo cha Hebei, makamaka Yongnian County, ndi gulu lalikulu. Mafakitole zikwizikwi. Chinyengo ndikuzindikira omwe ali ndi kuthekera koyenera zinki wakuda-yokutidwa hexagonal mabawuti, osati plating iliyonse ya zinki.

Mafakitole ambiri amapereka "zinki wakuda" koma njira yawo ndiyofunikira. Zinc wosanjikiza ukhoza kukhala woonda, wakuda wa chromate passivation ukhoza kukhala wotchipa, wamtundu umodzi woviika womwe umatha kukhala imvi. Muyenera kufunsa za njira yawo: Kodi ndi electroplating? Kodi makulidwe apakati opaka zinki (monga ma microns 8-12) ndi otani? Ndi muyeso wanji woyezetsa mchere womwe angakumane nawo (mwachitsanzo, maola 96 mpaka dzimbiri loyera pa ASTM B117)? Ngati sangathe kuyankha izi mwachangu, pitirirani.

Ndayendera magulu ngati Yongnian. Malo ndi mafakitale, akuluakulu ndi ang'onoang'ono. Mmodzi wodalirika yemwe ndagwira naye ntchito ndi Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd.. Ali m'boma la Yongnian, Handan, komwe kuli ziro pamakampaniwa. Malo omwe ali pafupi ndi mayendedwe akuluakulu monga Beijing-Guangzhou Railway ndi ma Expressways ndi mwayi wothandiza kwa zotengera - zotengera zimafika padoko (Tianjin/Xingang) bwino. Ndinawapeza zaka zingapo mmbuyomo pofufuza wondithandizira pulojekiti yotchinga mipanda yofuna kumaliza kwakuda kosasintha. Chomwe chinali chodziwika bwino chinali kuyang'ana kwawo pa zokutira. Amakhala ndi mizere yosiyanitsa yamitundu yosiyanasiyana, yomwe imachepetsa kuipitsidwa. Kwa zinc wakuda, amagwiritsa ntchito njira yotsekeka ya chromate, yomwe ili yabwinoko pakukhazikika komanso kuwongolera chilengedwe. Mutha kuwona mndandanda wawo pa https://www.zitaifasteners.com. Sikuti saizi iliyonse imakhala m'gulu la mabawuti omalizidwa, koma kusintha kwawo kuchokera kuzinthu zopangira kupita kuzinthu zopukutidwa kunali kopikisana.

Kufotokoza Ndendende Zomwe Mukufunikira

"Black zinc-plated hex bolt" ndi poyambira. Mdierekezi ali mwatsatanetsatane zomwe muyenera kulumikizana nazo. Kalasi/zinthu: Kodi mumatsatira kalasi ya carbon 4.8, 8.8, kapena 10.9? Kapena mwina chitsulo chosapanga dzimbiri (monga 304 kapena 316) chokhala ndi zokutira zakuda? Imeneyi ndi njira yosiyana kwambiri, yomwe nthawi zambiri imakhudza vapor deposition (PVD) yomwe imakhala yotsika mtengo. Zinc wakuda wambiri amakhala pazitsulo za carbon.

Makulidwe: Osati kutalika ndi m'mimba mwake, koma ulusi (wabwino kapena wokhuthala), komanso ulusi wonse kapena pang'ono. Ma radius apansi pamutu amafunikira pakugwiritsa ntchito kupsinjika kwakukulu. plating yokha: Nenani ngati mukufuna kuti igwirizane ndi RoHS (palibe chromium ya hexavalent pagawo la passivation). Otsatsa abwino ambiri tsopano amagwiritsa ntchito trivalent chromate, yomwe ili yotetezeka ku chilengedwe ndipo imapatsa mtundu wakuda womwewo. Nthawi ina ndinayiwala kutchula trivalent chromate ya chinthu chomangidwa ndi EU ndipo ndinali ndi mutu wotsatira miyambo.

Kupaka ndi kulemba. Kodi mumafuna zikwama za polyethylene? Mabokosi a makatoni? Chizindikiro cha laser pamutu? Kwa kufufuza, izi zingakhale zofunikira. Wopanga wabwino ngati Zitai amatha kugwira ntchito zachiwirizi mnyumba, zomwe zimathandizira zinthu. Nthawi zonse, pezani zitsanzo zovomerezeka musanavomereze kupanga kwathunthu. Lipirani kutumiza kwa DHL. Ndikoyenera kugwira gawo la thupi, fufuzani zoyenera ndi nati / washer wanu, ndikuyesa mwamsanga kumamatira (mayeso a tepi-hatch) pa zokutira.

Mavuto Abwino Ndiponso Mmene Mungawapewere

Ngakhale ndi gwero lodalirika, zinthu zikhoza kusokonekera. Kukwezedwa kwa haidrojeni ndi chiwopsezo chambiri chokhala ndi ma bawuti amphamvu kwambiri a electroplating (Giredi 10.9 ndi pamwambapa). Njira yopangira plating imatha kuyambitsa haidrojeni muchitsulo, ndikupangitsa kuti ikhale yolimba ndikupangitsa kuchedwa kulephera. Wopanga aliyense waluso ayenera kuphika zomangira zake zolimba kwambiri akamaliza kuyika (nthawi zambiri pa 190-220 ° C kwa maola angapo) kuti atulutse haidrojeni. Funsani mbiri yawo yophika. Ndinaphunzira izi movutikira pa chida cholemera; tinali ndi bolt snap panthawi yoika. Wogulitsayo adalumpha njira yophika kuti asunge nthawi ndi mtengo.

Kusiyanasiyana kwa makulidwe a zokutira. Pa a bawuti ya hexagonal, chophimbacho chikhoza kukhala chochepa pamphepete ndi m'makona a mutu wa hex. Pulata yabwino idzagwiritsa ntchito rack yoyenera ndi kachulukidwe kameneka kuti muchepetse izi. Funsani lipoti la mayeso losonyeza miyeso yochokera kumutu, shank, ndi ulusi. Kufanana ndikofunikira pachitetezo cha dzimbiri komanso kukongola.

Kusasinthasintha kwamitundu pamagulu. Izi ndi zazikulu kwa mapulogalamu owoneka. Mtundu wakuda wa chromate ukhoza kusuntha pang'ono potengera madzi osambira komanso nthawi yomiza. Ngati mukupanga projekiti yazaka zambiri, pemphani kuti wogulitsa azisungitsa gulu la chromate chemistry kapena asunge tsatanetsatane wazinthu. Apatseni zitsanzo zovomerezeka zomwe angagwirizane nazo pakapangidwe kalikonse.

Njira Yopezera: Kulinganiza Mtengo, Nthawi Yotsogolera, ndi Zowopsa

Pazofuna kamodzi, khalani ndi wogawa wakomweko kapena wadziko lonse. Kusiyanasiyana kwa mtengo sikuli koyenera kuvutitsa kuitanitsa. Kuti mugwiritse ntchito pachaka kapena ntchito yayikulu, pangani ubale wachindunji ndi opanga 1-2. Gwiritsani ntchito wothandizira ngati simukumasuka ndi kulumikizana mwachindunji ndi kuyang'anira bwino, koma wothandizira wabwino amawonjezera 5-10% mtengo. Kwa chinthu chokhazikika ngati zitsulo zakuda za zinc, mutha kuyang'anira mwachindunji mukangoyesa fakitale.

Konzani kuchuluka kwa kuyesa kaye. Ngakhale zitsanzozo zinali zangwiro, gulu loyamba lopanga likhoza kukhala losiyana. Onjezani zidutswa 1000, ziyeseni bwino-macheke amiyeso, ubale wamakanikidwe, kuyesa zokutira. Kenako onjezerani.

Logistics nkhani. FOB ku fakitale yawo? EXW? Ndani amayang'anira zonyamula katundu ku China? Kampani ngati Handan Zitai, yomwe ili m'malo opangira zinthu zokhala ndi maulalo abwino a mayendedwe, nthawi zambiri imakhala ndi izi mokhazikika. Nthawi zambiri amatha kukonza zotumiza kudoko. Ntchito yanu ndikuyika mzere wotumiza katundu wodalirika wa mwendo wanyanja / mpweya ndi chilolezo cha miyambo kumapeto kwanu.

Kotero, kuti kugula izo? Si yankho limodzi. Ndi flowchart: Voliyumu yanu ndi yotani? Nthawi yanu ndi yotani? Kodi ntchitoyo ndi yofunika bwanji? Kwa ambiri, ulendowu umathera pamakampani ogulitsa odalirika. Kwa iwo omwe ali ozama pakupanga kapena kumanga kwakukulu, yankho limatsogolera kumalo ngati Yongnian, ndi kwa opanga omwe amakhala ndi kupuma zomangira, kumene kulamulira kwenikweni kwa ndondomeko ndi khalidwe lagona. Ndiko komwe mumapeza odalirika, okwera mtengo zinki wakuda-yokutidwa hexagonal mabawuti, osati katundu wogula, koma chigawo chomwe mungatchule molimba mtima.
