Engineering lub Hex Flange Tus Kheej Drilling Screw: Cov Txheej Txheem Txheej Txheem

Hauv kev lag luam fastener, Hex Flange Self Drilling Screw (feem ntau hu ua SDS) yog qhov yooj yim deceptively. Rau lub qhov muag uas tsis tau kawm, nws tsuas yog ib lub bolt nrog ib tug xyaum taw tes. Txawm li cas los xij, ntawm Handan Dongchao Hardware Products Co., Ltd, peb nkag siab tias qhov kev ntseeg tau ntawm lub fastener no yog nyob ntawm qhov sib npaug ntawm qhov sib npaug ntawm qhov sib npaug ntawm qhov sib npaug ntawm qhov taw tes hardness thiab cov ntsia hlau lub cev lub zog tensile.
Tsis zoo li tus qauv tshuab screws, SDS yuav tsum ua ob qho kev tawm tsam ib txhij: nws yuav tsum nyuaj txaus los txiav los ntawm steel purlins (txog 6 hli) yam tsis muaj dulling, tsis tau ductile txaus los tiv taus siab torque thaum lub sij hawm installation tsis snapping. Nplooj ntawv no qhia txog seb peb ua tiav qhov nyiaj tshuav li cas hauv peb qhov chaw tsim khoom.

Lub Metallurgy: daws qhov teeb meem "Brittleness".

Ib qho ntawm qhov ua tsis tau zoo tshaj plaws hauv tus kheej -drilling screws yog "nkig tawg," qhov twg lub laum taw tes snaps tawm hauv cov nqaj hlau. Qhov no feem ntau tshwm sim thaum cov txheej txheem kho cua sov yog rushed los yog tsis sib haum.
Peb cov txheej txheem tsim khoom siv C1022 Carbon Steel lossis 1022A Alloy Steel, tau los ntawm sab saum toj -tier mills. Lub sijhawm tseem ceeb yog peb lub voj voog quenching thiab tempering. Peb tsom lub hardness ntawm HRC 56-60 rau qhov xyaum taw tes, thaum tuav ib tug tseem ceeb hardness uas tso cai rau ductility.
Qhov tshwm sim: Cov ntsia hlau xyaum ua kom huv si los ntawm 3mm mus rau 6mm steel (nyob ntawm tus qauv) tab sis khaws cov kev hloov pauv txaus kom khoov me ntsis hauv qhov hnyav ntau dua li tsis tawg. Qhov no tsis yog -tus qauv sib tham tau rau peb daim ntawv pov thawj ISO 9001.

Txheej Technology: Tshaj Standard Zinc

Rau kev lag luam xa tawm, tshwj xeeb tshaj yog nyob rau sab hnub tuaj Asia thiab Middle East, tus qauv electro-zinc plating (dawb los yog daj) feem ntau tsis txaus vim cov av noo thiab cov dej qab ntsev. Peb tau hloov peb cov kab ntau lawm los siv Ruspert Txheej txheej txheem.
Qhov no tsis yog tsuas yog ib txheej txheej; nws yog ib daim ntawv thov sib xyaw.
Zinc Txheej: Muab kev tiv thaiv thawj zaug.
Aluminium Flake Layer: Tsim lub cev thaiv kev tiv thaiv kev ya raws.
Ceramic Topcoat: Seals lub micro- pores.
Hauv peb lub chaw kuaj mob sab hauv, peb yuav raug batch rau ASTM B117 Ntsev Txau Test. Thaum cov txheej txheem zinc ntsia hlau feem ntau pom cov xeb liab hauv 24 mus rau 48 teev, peb Ruspert- kho hex screws tsis tu ncua ntau dua 1000 teev. Rau cov neeg ua haujlwm vov tsev, cov ntaub ntawv no txhais tau hais tias muaj kev tiv thaiv "liab xeb" los ntshav los ntawm lub ru tsev panels rau ntau tshaj kaum xyoo.

Tsim Efficiency: Lub taub hau Hex Washer

Los ntawm kev tsim engineering foundations, lub taub hau hex flange (DIN 7504K tus qauv) ua haujlwm rau lub hom phiaj tshwj xeeb. Cov flange kev sib xyaw ua ke ua ib qho ua tau - hauv tshuab ntxhua khaub ncaws, ua rau thaj tsam ntawm cov kabmob. Qhov no faib cov clamping quab yuam hla thaj tsam dav ntawm cov ntawv hlau, txo qhov kev pheej hmoo ntawm cov ntsia hlau rub los ntawm cov khoom thaum lub sij hawm siab - cua xwm txheej.
Peb kuj tshuab qhov chaw so kom nruj kom haum 8mm lossis 10mm hex tsav tsheb. Ib qho kev tsis txaus siab hauv kev ua lag luam yog "cam- tawm" (slippage), uas ua rau lub taub hau ntsia hlau puas. Peb tuav nruj tolerances ntawm lub hex geometry los xyuas kom meej qhov siab tshaj plaws torque hloov los ntawm tus neeg tsav tsheb cuam tshuam rau cov ntsia hlau.
Daim ntawv qhia txog kev yuav khoom
Rau peb cov neeg koom tes B2B thiab cov neeg ua haujlwm yuav khoom, ntawm no yog cov qauv ntsuas peb khaws cia hauv Tshuag. Kev cai ntev yog muaj raws li qhov kev thov.

Hais txog Handan Dongchao Hardware Products Co., Ltd
Peb tsis yog lub tuam txhab lag luam; peb yog cov chaw tsim khoom. Nyob rau hauv Handan, lub hub keeb kwm rau kev tsim kho vajtse, peb lub chaw tsom xyuas nruj me ntsis ntawm kev sib tw fastener. Peb nkag siab tias rau peb cov distributors, ib pawg tsis zoo tuaj yeem ua rau lawv lub koob npe nrov. Yog li ntawd, peb qhov kev tswj xyuas kom zoo yog tsom rau cov ntsiab lus "dhuav" - xov zoo sib xws, taw tes concentricity, thiab txheej adhesion- uas tseem ceeb ntawm qhov chaw ua haujlwm.
Thov Daim Ntawv Teev Npe Technical (TDS)
