Dacromet-Coated Hex Socket Head Cap Screws DIN 912 Standard

2026-08-17

Iyo Yakakwana Tekinoroji Yekutarisa yeDacromet Surface Kurapa uye Socket Musoro Cap Screw Matsanangudzo

1. Nhanganyaya

Dacromet-coated hex socket head cap screws inoenderana neDIN 912 yakajairwa inomiririra yakakwira-inoshanda yekumisikidza mhinduro inosanganisa iyo mechanical kunaka kweiyo precision-engineered socket head cap screws pamwe nepamusoro corrosion resistance yeDacromet surface treatment. Aya ma fasteners anoshandiswa zvakanyanya mumotokari, kuvaka, yemugungwa, simba remhepo, uye maindasitiri emuchina mashandisirwo uko zvese kutendeseka kwechimiro uye yenguva refu yekudzivirira corrosion yakakosha.

Ichi chinyorwa chinopa yakadzama tekinoroji yekutarisa kubva pamaonero maviri: iyo Dacromet yekupfekedza maitiro, ayo anopa aya mabhanhire akasarudzika e-anti-corrosion zvivakwa, uye iyo DIN 912 socket head cap screw geometry, iyo inotsanangura dhizaini yavo yekugadzira uye zviyero.

2. Dacromet Coating Technology

Dacromet inyanzvi yepamberi, yakavakirwa mvura, ine hushamwari inorwisa-corrosion coating tekinoroji yakagadziridzwa seimwe nzira kune yechinyakare electroplating. Iyo isiri-electrolytic dip spin coating system inoumbwa ne-ultra-fine zinc flakes, aluminium flakes, chromic acid makomisheni, uye akasarudzika organic binder. Kana yaporeswa patembiricha dzakakwirira, zvinhu izvi zvinoumba simbi yakakora, yakawanda-yakaiswa simbi inosungirirana nesimbi kune substrate yesimbi.

Kusiyana neyakajairwa electroplating, iyo inovimba ne electrolytic deposition, Dacromet inoshandisa dip-spin kana dip-drain process. Mafasteners anonyudzwa muDacromet liquid coating, obva aiswa centrifuged kubvisa zvinhu zvakawandisa, uye pakupedzisira anobikwa paanenge 300 degrees Celsius. Iyi nzira yekurapa inokonzeresa kuti zinc nealuminium flakes kuti inyungurudze uye inyunguduke pamwechete, ichigadzira sirivheri-grey, inonamira inodzivirira layer.

Iyo Dacromet coating process ine akati wandei akanyatso kudzora matanho:

Danho	Process	Tsanangudzo
1	Degreasing	Kubviswa kwemafuta, mafuta ekuzora, uye zvinosvibisa pamusoro uchishandisa alkaline cleaning agents
2	Shot Blasting	Mechanical yekuchenesa kubvisa chikero, ngura, uye oxide maseru kubva pafastener pamusoro
3	Dip-Spin Coating	Kunyudzwa muDacromet liquid coating inoteverwa necentrifugal spinning kudzora ukobvu hwekuputira
4	Kutanga Kurapa	Kubika pa 80-120 madhigirii celsius kufefetedza unyoro uye kugadzira firimu rekutanga
5	Chechipiri Dip-Spin	Optional chechipiri coating layer yekunatsiridza corrosion dziviriro
6	Kurapa Kwekupedzisira	Kubika pa 280-320 madhigirii Celsius kusvika sinter zinc / aluminium flakes uye kugadzira yekupedzisira yekudzivirira layer.
7	Kutonhodza & Kuongorora	Kutonhodzwa kunodzorwa kunoteverwa nekuongororwa kwemhando yekukoira, kunamatira, uye kutaridzika

3. DIN 912 Socket Head Cap Screws

DIN 912 iGerman Industrial Standard iyo inotsanangura hukuru, kushivirira, uye michina zvimiro zvehex socket head cap screws, inozivikanwawo seAllen mabhaudhi kana socket head cap screws. Izvi zvinosungirira zvine musoro wecylindrical une hexagonal socket drive, yakagadzirirwa kufambiswa neAllen wrench (hex kiyi). Iyo DIN 912 chiyero yakagamuchirwa zvakanyanya pasi rose uye inoshanda yakaenzana neISO 4762.

Socket head cap screws inoratidzirwa neyakakura simba-kusvika-saizi ratio. Iyo cylindrical musoro dhizaini inobvumira yakakwirira clamping masimba kana ichienzaniswa neyakajairwa hex musoro screws yedhayamita imwechete, nepo yemukati hex drive inogonesa kuisirwa munzvimbo dzakavharirwa dzisina kubvumidzwa. Musoro unogara wakanyunguduka kana kuti pasi penzvimbo yekubatana kana waiswa mugomba rakapoteredzwa, zvichipa kutaridzika kwakachena, kwakaderera.

3.3 Mechanical Properties

DIN 912 socket head cap screws inogadzirwa kubva kwakasiyana zvinhu uye inowanikwa mumakirasi akawanda ezvivakwa. Makirasi akajairika ezvivakwa zve socket head cap screws ndeye 8.8, 10.9, uye 12.9, izvo zvinoratidza kuwedzera tensile simba mazinga.

Property Kirasi	Material	Min. Tensile Simba (MPa)	Min. Goho Simba (MPa)	Kuoma (HRC)
8.8	Carbon Steel	800	640	22-32
10.9	Alloy Steel	1000	900	32-39
12.9	Alloy Steel	1200	1080	39-44
A2-70	Stainless Simbi 304	700	450	-
A4-80	Stainless Simbi 316	800	600	-

4. Synergistic Benefits: Dacromet + DIN 912

Kana Dacromet coating ikaiswa kuDIN 912 socket head cap screws, mhedzisiro ndeye chisungo chinosanganisa yakasarudzika mechanicha kuita pamwe neyakatanhamara kudzivirira ngura. Iyi synergy inoita kuti Dacromet-yakavharwa socket head cap screws iyo yakasarudzika sarudzo munzvimbo dzinoda.

5. Mhedziso

Dacromet-yakavharwa DIN 912 socket head cap screws inomiririra mharadzano yeinjiniya yepamusoro yepamusoro uye dhizaini yekusimbisa chaiyo. Iyo Dacromet coating process inopa yakasimba, yezvakatipoteredza inokonzeresa corrosion barriers iyo inodarika yakajairwa electroplating neakakosha margin, nepo DIN 912 geometry inovimbisa yakakwirira clamping simba, yakanakisa dhiraivha kubatanidzwa, uye nzvimbo-inoshanda kuisirwa.

Pamwe chete, matekinoroji aya anoburitsa chinomhanyisa chinokwanisa kuita zvakavimbika munzvimbo dzinonyanya kudiwa maindasitiri. Sezvo maindasitiri achiramba achida hupenyu hurefu hwebasa, kuderedzwa kugadzirisa, uye maitiro ekugadzira anoenderana nenharaunda, Dacromet-yakavharwa socket head cap screws icharamba iri chinhu chakakosha muinjiniya nekuvaka pasi rese.

Kune zvikwata zvekutenga uye zveinjiniya, kutsanangura Dacromet-yakavharwa DIN 912 socket head cap screws inova nechokwadi chekutevedzwa nepasi rose corrosion dziviriro zviyero uku uchichengetedza mashandiro emakanika anodiwa pakuchengetedza-akakosha maapplication.
