Dacromet-Coated Hex Socket Head Cap Screws DIN 912 Standard

2026-08-17

Kuwunikira Kwatsatanetsatane Kwaukadaulo wa Dacromet Surface Treatment ndi Socket Head Cap Screw

1. Mawu Oyamba

Dacromet-coated hex socket head cap screws zogwirizana ndi DIN 912 standard imayimira njira yolimbikitsira kwambiri yomwe imaphatikiza luso la makina opangira zomangira za socket head cap ndi kukana kwa dzimbiri kwa Dacromet surface treatment. Zomangamangazi zimagwiritsidwa ntchito kwambiri pamagalimoto, zomangamanga, zam'madzi, mphamvu zamphepo, komanso makina opangira mafakitale pomwe kukhulupirika kwadongosolo komanso kuteteza dzimbiri kwanthawi yayitali ndikofunikira.

Nkhaniyi ikupereka chithunzithunzi chatsatanetsatane chaukadaulo kuchokera kunjira ziwiri: njira yokutira ya Dacromet, yomwe imapatsa zomangira izi zida zawo zotsutsana ndi dzimbiri, ndi DIN 912 socket head cap screw geometry, yomwe imatanthawuza kapangidwe kawo kamakina ndi milingo yawo.

2. Dacromet Coating Technology

Dacromet ndiukadaulo wapamwamba, wotengera madzi, woteteza zachilengedwe wothana ndi dzimbiri wopangidwa ngati m'malo mwa electroplating yachikhalidwe. Ndi makina osagwiritsa ntchito electrolytic dip spin coating omwe amapangidwa ndi ma ultra-fine zinc flakes, aluminium flakes, chromic acid compounds, ndi ma binder apadera apadera. Zikachiritsidwa pa kutentha kokwera, zigawozi zimapanga zokutira zazitsulo zamitundu yambiri zomwe zimagwirizanitsa ndi zitsulo ku gawo lapansi lachitsulo.

Mosiyana ndi electroplating wamba, yomwe imadalira electrolytic deposition, Dacromet imagwiritsa ntchito dip-spin kapena dip-drain process. Zomangira zimamizidwa mu zokutira zamadzimadzi za Dacromet, kenako zimayikidwa kuti zichotse zinthu zochulukirapo, kenako zimaphika pafupifupi 300 digiri Celsius. Kuchiritsa kumeneku kumapangitsa kuti zinki ndi aluminiyamu ziwombankhane komanso zisungunuke palimodzi, ndikupanga siliva-imvi, wosanjikiza woteteza kwambiri.

Njira yokutira ya Dacromet imakhala ndi magawo angapo oyendetsedwa bwino:

Khwerero	Njira	Kufotokozera
1	Kuchepetsa mafuta	Kuchotsa mafuta, mafuta, ndi zonyansa zapamtunda pogwiritsa ntchito mankhwala oyeretsera alkaline
2	Kuwombera Kuwombera	Kuyeretsa pamakina kuti muchotse masikelo, dzimbiri, ndi oxide pamwamba pa cholumikizira
3	Dip-Spin Coating	Kumizidwa mu zokutira zamadzimadzi za Dacromet zotsatiridwa ndi kupota kwapakati kuti muzitha kuwongolera makulidwe
4	Kuchiritsa Kwambiri	Kuphika pa 80-120 digiri Celsius kuti asungunuke chinyezi ndikupanga filimu yoyamba
5	Dip-Spin Yachiwiri	Wosanjikiza wachiwiri wokutira kuti atetezedwe ku dzimbiri
6	Kuchiritsa komaliza	Kuphika pa 280-320 digiri Celsius kuti sinter zinc / aluminiyamu flakes ndi kupanga wosanjikiza omaliza chitetezo
7	Kuzizira & Kuyang'ana	Kuziziritsa koyendetsedwa kumatsatiridwa ndi kuwunika kwabwino kwa makulidwe a zokutira, zomatira, ndi mawonekedwe

3. DIN 912 Socket Head Cap Screws

DIN 912 ndi German Industrial Standard yomwe imatchula kukula, kulolerana, ndi makina azitsulo za hex socket head cap, zomwe zimadziwikanso kuti Allen bolts kapena socket head cap screws. Zomangira izi zimakhala ndi mutu wa cylindrical wokhala ndi socket socket drive, yopangidwa kuti iziyendetsedwa ndi Allen wrench (kiyi ya hex). Muyezo wa DIN 912 walandiridwa padziko lonse lapansi ndipo umagwira ntchito mofanana ndi ISO 4762.

Zomangira za socket head cap zimadziwika ndi kuchuluka kwamphamvu kwa kukula kwake. Mapangidwe amutu wa cylindrical amalola kuti pakhale mphamvu zolimba kwambiri poyerekeza ndi zomangira zapamutu za hex za mainchesi omwewo, pomwe ma hex drive amkati amathandizira kuyika m'malo otsekeka opanda chilolezo chochepa. Mutu umakhala wonyezimira ndi kapena pansi pa malo okwerera pamene aikidwa mu dzenje lopingasa, kumapereka maonekedwe oyera, otsika.

3.3 Katundu Wamakina

DIN 912 socket head cap screws amapangidwa kuchokera kuzinthu zosiyanasiyana ndipo amapezeka m'magulu angapo a katundu. Makalasi odziwika bwino a zomangira za socket head cap ndi 8.8, 10.9, ndi 12.9, zomwe zikuwonetsa kuchulukira kwamphamvu kwamphamvu.

Kalasi ya Katundu	Zakuthupi	Min. Mphamvu ya Tensile (MPa)	Min. Mphamvu zokolola (MPa)	Kulimba (HRC)
8.8	Chitsulo cha Carbon	800	640	22-32
10.9	Aloyi Chitsulo	1000	900	32-39
12.9	Aloyi Chitsulo	1200	1080	39-44
A2-70	Chitsulo chosapanga dzimbiri 304	700	450	-
A4-80	Chitsulo chosapanga dzimbiri 316	800	600	-

4. Mapindu a Synergistic: Dacromet + DIN 912

Kupaka kwa Dacromet kukagwiritsidwa ntchito pazitsulo za DIN 912 socket cap cap, zotsatira zake zimakhala zomangira zomwe zimagwirizanitsa ntchito zamakina mwapadera ndi chitetezo chambiri cha dzimbiri. Synergy iyi imapangitsa Dacromet-yokutidwa ndi socket cap cap kuti ikhale chisankho chomwe mumakonda m'malo ovuta.

5. Mapeto

Zomangira za DIN 912 socket socket head cap zokhala ndi Dacromet zimayimira mphambano ya uinjiniya wapamwamba komanso kapangidwe kake kolumikizira. Dongosolo la zokutira la Dacromet limapereka chotchinga champhamvu, choteteza chilengedwe chomwe chimaposa ma electroplating wamba ndi malire ofunikira, pomwe DIN 912 geometry imatsimikizira kulimba kwamphamvu, kuyendetsa bwino kwambiri, komanso kuyika bwino kwa malo.

Pamodzi, matekinolojewa amapanga chomangira chomwe chimatha kugwira ntchito modalirika m'malo ovuta kwambiri amakampani. Pamene mafakitale akupitiriza kufunafuna moyo wautali wautumiki, kuchepetsa kukonza, ndi kupanga zinthu zogwirizana ndi chilengedwe, zomangira za Dacromet-zokutidwa ndi socket head cap zikhalabe gawo lofunika kwambiri pa zomangamanga ndi zomangamanga padziko lonse lapansi.

Kwa magulu ogula zinthu ndi ainjiniya, kutchula zomangira za socket za DIN 912 socket socket head cap zimathandizira kutsata miyezo yapadziko lonse lapansi yoteteza dzimbiri ndikusunga magwiridwe antchito ofunikira pakugwiritsa ntchito chitetezo.

Palibe. Kenako.
