Izikrufu zivamile kakhulu kangangokuthi abathengi abaningi abakaze bame bacabange ukuthi zivela kuphi, nokho umlando walesi sikhinzi esithobekile uchaza okuningi ngendlela umucu wokuhlinzeka wanamuhla osebenza ngayo. Ukuqonda indlela izikrufu ezathuthuka ngayo zisuka kusisetshenziswa esilula sokukhuphula amanzi ngokhuni zaba yingxenye yezimboni eklanywe ngokunemba kusiza abaphathi bokuthenga ukuthi bahlole ikhwalithi, ukubekezelelana, kanye nenani ngokunemba okukhulu. Isikrufu kungenzeka ukuthi siyisikhinzi esibaluleke kakhulu semishini emlandweni wesintu, sihlanganisa konke kusuka kuma-smartphone kuya ezakhiweni ezinde. Kubangenisi nabasabalalisi, lowo mlando awuyona into engabalulekile; iyimephu yezindlela zokukhetha izinto, amazinga emicu, kanye nezindlela zokukhiqiza ezisabumba izintengo nanamuhla. Umthengi oqonda ukuthi kungani ikhanda le-countersunk likhona nokuthi kungani isikrufu se-robertson sinekhwelo eliyisikwele uzoxoxisana kangcono futhi acacise ngokunemba okwengeziwe. Lo mhlahlandlela ulandela umlando ophelele wezikrufu bese uxhumanisa nalowo mbuzo osebenzayo wonke ithimba lokuthenga elibhekana nawo: yikuphi lapho izikrufu ezinokwethenjelwa, ezinentengo enhle zingatholakala khona ngesilinganiso esikhulu?

Indaba ngokwesiko iqala ngo-Archytas waseTarentum, isazi sefilosofi nesazi sezibalo esingumGreki, cishe ngo-400 BC, owachaza umshini oyindilinga osetshenziselwa ukuhambisa amanzi. Kusukela kulokho kusungulwa okukodwa, izikulufu zathuthuka phakathi neminyaka eyizinkulungwane ezimbili zaba yizinto zokubopha ezibalulekile zemboni esizethembayo namuhla, izinhlobo zemisonto, izinhlobo zokushayela, kanye nezingubo zokumboza zithuthukiswe izinkulungwane zezinhlelo ezikhethekile. Uhambo lwaluhamba kancane ekuqaleni, ngoba ukusika i-helix enembile ngesandla kwakunzima kakhulu futhi kudula kakhulu. Kuphela lapho kufika umshini wokusika izikulufu lapho izikulufu zaba zishibhile ngokwanele ukuba zisetshenziswe ekwakheni kwansuku zonke nasemishinini. Namuhla imboni yezinto zokubopha iyimboni yomhlaba wonke, ilinganiswe kakhulu, futhi incintisana kakhulu ngentengo nesikhathi sokuhola. INorvion Supply Chain (China) isemkathini yaleyo mboni njengomhlinzeki wezikulufu onikeza ukulawulwa kwekhwalithi okuqinile, ukukhiqiza ngokwezifiso, kanye nentengo encintisanayo kubathengi emhlabeni wonke.

Izikulufu zokuqala zazingezona izinto zokubopha kodwa zazingomshini wokucindezela nokuphakamisa. Onjiniyela abangamaGreki nabamaRoma basebenzisa izikulufu ezinkulu zokhuni kumishini yokucindezela ukukhipha ijusi yamagilebhisi namafutha omnqumo, beguqula ukunyakaza okuyindilinga kube amandla agxilile, anamandla omugqa. Izinguqulo zakamuva zalesi simiso esifanayo zasetshenziselwa ukukhuphula amanzi okunisela nokukhipha amanzi angcolile emikhunjini, umsebenzi owawudinga isikulufu esivalekile esijikelezayo ngaphakathi komgqomo wokhuni. Le mishini yayinkulu ngokwezilinganiso zanamuhla, ngokuvamile ibaziwe isuka esigodweni esisodwa futhi iqiniswe ngamabhande ethusi noma insimbi. Ngenxa yokuthi isikulufu ngasinye kwakufanele sibunjwe ngasinye, ukukhiqiza kwakuhamba kancane futhi imikhiqizo eyayiphuma yayigcinelwe izindawo zokuhlala ezicebile, amathempeli, nemikhumbi yezempi. Isikulufu, empeleni, sasiyingxenye yempahla yokusebenza esemqoka kunokuba kube into elahlwayo. Lelo qiniso lezomnotho lichaza ukuthi kungani lobu buchwepheshe basakazeka kancane kancane amakhulu eminyaka kamuva.

Njengoba isidingo sasikhula, izikulufu zathola indlela yazo emishinini yokwenza iphepha nokunyathelisa, lapho ukucindezela okungaguquki kwakubalulekile ukuze kube nemibhalo ehlanzekile namashidi afanayo. Ukusabalala kwalezi zinhlelo kwakusavinjelwe ubunzima bokukhiqiza, njengoba umdwebi onekhono wayengakwazi ukukhiqiza izikulufu ezimbalwa ezinembile ngosuku. Ukusungulwa komshini wokusika izintambo zikazibuthe ngasekupheleni kwekhulu leshumi nesishiyagalombili nasekuqaleni kwekhulu leshumi nesishiyagalolunye kwashintsha isimo ngokuvumela izintambo ukuthi zisikwe ngomshini futhi ziphindwe zifane ngepitch efanayo. Ngokushesha izikulufu zase zikwazi ukukhiqizwa ngenani elikhulu, futhi onjiniyela baqala ukuzicacisa zokuthi zisetshenziselwe izinjini zomusi, amabhuloho, imisele, nemigwaqo. Izibopho ezintambo ezisemthethweni ezinemisonto zenza izakhiwo ezinkulu zensimbi zisebenze ngoba amalunga ayekwazi ukuqiniswa, ahlolwe, futhi kamuva alungiswe. Lokhu kushintsha kusuka entweni eyakhelwe umuntu oyedwa kuya empahleni esemthethweni yisikhathi lapho imboni yesimanje yezibopho yazalwa ngempela.

Ama-screw aqala ukuthandwa ngempela phakathi nawo-1400s, lapho ama-screw ensimbi aqala ukuvela efanitshini, ezikhwameni zempi, kanye nemishini yokuqala, kodwa ahlala eyinto yamakhono amakhulu amanye amakhulu amathathu eminyaka. Ukukhiqizwa kwefektri kwafika phakathi nawo-1700s, lapho izindawo zokusebenza ezihleliwe eYurophu zaqala ukuhlukanisa ukwenziwa kwama-screw ngezinyathelo ezihlukene ezenziwa ngabasebenzi abahlukene. Ama-1840s aletha imishini yokuqala yokukhiqiza ngobuningi, eyayikwazi ukwakha nokufaka izintambo kuma-screw ngokushesha nangokushibhile ngokwanele ukuba abakhi abajwayelekile bazisebenzise ngokukhululekile. Ukufana kwalandela kamuva kakhulu, lapho i-National Screw Thread Commission yasungula izincazelo zentambo ezihlangene ngo-1928, yaqeda isikhathi lapho izintambo ezingafani zazichitha isikhathi esiningi kanye nezinto eziningi. Namuhla isikali siyamangaza: ngaphezu kwezigidigidi ezingama-200 zama-screw asetshenziswa e-United States kuphela unyaka nonyaka. I-Norvion Supply Chain (China) isekela lolo hlobo lwesidingo ngomthamo wokukhiqiza okhulayo kanye nobuchwepheshe obujulile bokuthumela ngaphandle, ukuze abathengi bakwazi ukuhlela amavolumu ngokuzethemba.

Lelo zinga lenzeka kuphela ngenxa yokushintshana okudalwe ukufana kwezindinganiso. Ngaphambi kwezindinganiso zomhlaba wonke zentambo, umakhenikha obhekene nesikulufu esigxiliwe noma esikhunyuliwe wayevamise ukungabi nasinye isisombululo esisebenzayo ngaphandle kokusibhoboza bese ephinda eqopha umgodi. Izikhathi ezilinganiselwe kanye nosayizi wamakhanda kwashintsha isimo sokulungisa ingunaphakade, kwavumela ukushintshwa okusheshayo nokulindelekile noma kuphi emhlabeni. Izinhlelo zokushayela nazo zahlukahluka: isikulufu sika-Robertson esinesikwele esicashile, esasungulwa eCanada ekuqaleni kwekhulu lamashumi amabili, sanciphisa ukuphuma kwe-cam futhi sathuthukisa ukushayela ngesandla esisodwa emsebenzini kagesi nowamakhabethe. Kamuva kwafika izindawo eziwumgqamuzana, amasokhethi e-hex, namakhanda anciphisa i-torque, ngayinye ixazulula inkinga ethile yokuhlanganisa. Kubangenisi, lo mlando uyisikhumbuzo sokuthi izindinganiso zentambo, ukuma kwekhanda, nohlobo lokushayela akuzona izincazelo ezishintshanayo; ziyizicaciso ezinquma ukuthi umthwalo uzolingana yini nokusetshenziswa kwekhasimende.

Ama-self-drilling screws, aziwa kabanzi ngokuthi ama-Tek screws, aklanywa yi-Buildex, eyasungula umqondo wokuqala wokufaka i-drill bit ngqo ekugcineni kwesikulufu. Leyo phoyinti encane yokubhoboza yasusa isidingo sokubhoboza umgodi wokuqala, ngakho umsebenzi oyedwa onethuluzi elilodwa wayekwazi ukuhlanganisa insimbi nensimbi ngemizuzwana. Umklamo wokuqala wawunamakhanda amade anemisindo emikhulu ayekwazi ukubanjwa ngokuqinile futhi ayevula umgodi kancane njengoba isikulufu sihlala. Lokhu kwakuyintuthuko yangempela kubakhi bezakhiwo, njengoba kwasusa isinyathelo esiphelele emisebenzini yokufulela, ukugqoka, kanye nokwakha ngezinsimbi. Ngeshwa, izinga lekhwalithi lehlile kwezinye izingxenye zemakethe, futhi abanye abangenisi baye banciphisa ukujiya kwezinto kanye nesisindo sokumboza ukuze banciphise izindleko, bakhiqize izikulufu eziphukayo, ezigqwalayo, noma ezigqwala ngaphambi kwesikhathi. I-Norvion Supply Chain (China) ihlinzeka ngezikulufu ze-Tek-style self-drilling zekhwalithi ephezulu ezinezinto ezingaguquguquki, ukumboza okulawulwayo, kanye nokusebenza okuqinisekisiwe ukuze abakhi bezakhiwo bangakhokhi kabili ngesikulufu esishibhile.

Ukukhetha uhlobo lwesikulufu olulungile kungenye yezinqumo ezibaluleke kakhulu kunoma yikuphi ukuhlanganisa, ngoba ukukhetha okungalungile kuholela ekhanda elikhihlikile, isisekelo esiqhekekile, ukugqwala kwe-galvanic, kanye nokwehluleka kokuhlangana kwangaphambi kwesikhathi. Izigaba zokuklama zibaluleke kakhulu kunalokho abathengi abaningi abakucabangayo: uhlobo lwe-drive lunquma ukuthi i-torque idluliswa kanjani, isitayela sekhanda sinquma ukuthi umthwalo usatshalaliswa kanjani nokuthi isikulufu singahlala yini sicwebe, futhi uhlobo lwephoyinti lunquma ukuthi isikulufu singaqala sodwa yini noma sidinga ukubhobozwa kuqala. Ikhanda le-countersunk, isibonelo, livumela isikulufu ukuthi sihlale sicwebe noma ngaphansi kwendawo, okubalulekile kuma-hinge, amapuleti, nanoma yikuphi ukuhlangana okufanele kuhlale kubushelelezi. Isikulufu se-cannulated sinomgogodla ongenalutho esivumela ukuthi sifakwe entanjeni yokuqondisa, umklamo osetshenziswa kakhulu ekuhlinzeni kwamathambo nasemsebenzini wokuqondanisa ngokunemba. Ukuqonda lezi zigaba kwenza kube lula kakhulu ukucacisa umkhiqizo olungile nokuhlola ukuthi ikhathalogi yomhlinzeki iphelele ngempela yini. Kusiza futhi abathengi ukubona ingozi yokushintshwa, lapho isikulufu esishibhile sinikezwa ngokuthula esikhundleni sengxenye ecacisiwe.

Ama-Tek screws asetshenziswa kakhulu ezinhlelweni zensimbi-kuya-ensimbi lapho isivinini nokudonsa okuthembekile kubaluleke kakhulu kunokubukeka. Amaphuzu awo okuzibhoboza ahlaba ngezingcwecwe zensimbi ezincane, i-aluminium, nezingxenye zensimbi ezincane ngaphandle komgodi wokuqala, yingakho ebusa emisebenzini yamapayipi e-HVAC, ukwakhiwa kwensimbi yamashidi, nophahla lwensimbi. Ophahleni, inhlanganisela yephuzu lokubhoboza eliqinile, i-washer yokuvala, kanye ne-coating emelana nokugqwala kunquma ukuthi uphahla luzohlala lungangeni manzi amashumi eminyaka yini. Osonkontileka futhi bayazisa ama-Tek screws ngoba umsebenzi oyedwa angakwazi ukuqedela ukuxhumana ngaphandle kokushintsha amathuluzi noma ukuhlela kabusha, okunciphisa izindleko zabasebenzi ngokuxhumana ngakunye. Ngakho-ke abathengi kufanele baqinisekise ukuqina kwephuzu, uhlobo lwentambo, kanye nencazelo ye-coating esikhundleni sokuqhathanisa intengo yekhanda kuphela. I-Norvion Supply Chain (China) isiza abangenisi ukuthi bachaze lezi zincazelo ngokucacile bese ibambelela ekukhiqizeni kuzo isigaba ngasinye.

Izikulufu zethusi zisetshenziswa kakhulu ekufakweni kwemisele yamanzi, ekwakhiweni kwezakhiwo, nasekufuleleni ngamashidi ensimbi, lapho ukuqina nokubukeka kubaluleke ngokulinganayo. Ithusi ngokwemvelo imelana nokugqwala komoya, iguga ibe yi-patina ekhangayo, futhi iyagaywa kabusha ngokuphelele, okukwenza kube ukukhetha okusimeme kwezembozo zezakhiwo ezihlala isikhathi eside. Ngenxa yokuthi ithusi iqhuba kahle ugesi futhi inezinto ezibulala amagciwane ngokwemvelo, iphinde ithandwe ezibhedlela, ezindaweni zokucwaninga, nasezindaweni zokuhlanzeka lapho ukungcola kwendawo kuyinkinga yangempela. Emsebenzini wemisele yamanzi, izikulufu zethusi zimelana nokuchayeka okungapheli emanzini okubhubhisa izibophezelo ezingaphansi, zivimbele ukugoba nokuhlukana okuholela ekulimaleni kwamanzi. Ziphinde zisize ekulondolozeni ubuqotho bophahla ngokugcina umfutho wokucindezela ofanayo kuzo zonke izihloko kanye namaflekshi. Emaphrojekthi asezingeni eliphezulu, ukucacisa ithusi langempela esikhundleni sensimbi efakwe ithusi umehluko phakathi kwemininingwane yeminyaka engamashumi amahlanu nokulungiswa kweminyaka emihlanu.

Izikulufu zokhuni zenzelwe ngokukhethekile ukuthi zisetshenziswe okhunini futhi ngokuvamile zikhiqizwa ngebronze, ithusi, noma insimbi kuye ngamandla adingekayo nokubukeka. Imicu yazo emikhulu ingena ezintweni ezinemicu futhi iziqu zazo ezingenamicu zivumela ukuthi umhlangano udonswe uqine ngaphandle kokuthi imicu idabule ipulangwe eliphezulu. Le nhlanganisela yehlisa ukuqhekeka okuzungeze ikhanda futhi isiza ukuvimbela ukuqhekeka okonakalisa ifenisha eshibhile namakhabethe. Izigaba ezihlobene njengezikulufu zikakhonkolo nezikulufu ze-drywall zilandela umqondo ofanayo, zisebenzisa i-geometry yemicu ekhethekile namaphrofayili ekhanda okwamatshe okwakha nebhodi le-gypsum ngokulandelana. Ukukhetha ubude obufanele, isilinganiso, kanye nomgodi wokushayela kubalulekile, ngoba isikulufu esikhulu kakhulu esigabeni esincane sizoqhekeza izingodo kungakhathaliseki ukuthi senziwe kahle kangakanani.

Sidumile emsebenzini kagesi, ekwenzeni amakhabethe, kanye nanoma yikuphi lapho umsebenzi edinga ukubamba isikulufu ebhithini ngaphandle kwesandla sesibili. Abathengi abafuna izikulufu zesitayela sika-Robertson kufanele baqinisekise ukujula komgodi kanye nokubekezelelana, ngoba umgodi oyisikwele ogqagqayo wehlula inzuzo enkulu yomklamo.

I-Norvion ihlanganisa ukuhlolwa kwabahlinzeki, ukuhlolwa kwefektri, ukuhlolwa phakathi nenqubo yokukhiqiza, kanye nokuhlolwa kwangaphambi kokuthunyelwa kanye nokuhlolwa kwabantu besithathu uma kudingeka. Ukulandelelwa kwezinto ezisetshenziswayo, ukuqinisekiswa kobukhulu, ukuhlolwa kwe-torque, kanye nokuhlolwa kwe-salt spray kunikeza ubufakazi obhalisiwe bokusebenza ngaphambi kokuthunyelwa. Izitifiketi ezihlanganisa i-ISO, i-RoHS, i-REACH, kanye namazinga aqondene nomkhakha zinikezwa njengokujwayelekile, kanye nokusekelwa kwezinto zokupakisha, ukulebula, kanye nemibhalo.

Yebo, i-Norvion inikeza izinsizakalo ze-OEM ne-ODM ezihlanganisa izikulufu ezinophawu lwangasese kanye nemiklamo ekhethekile eyakhiwe ngemidwebo yamakhasimende noma amasampula abonakalayo. Inkampani isebenza ngezinsimbi ezingagqwali, insimbi yekhabhoni, ithusi, ibhulonzi, ithusi elibomvu, kanye nensimbi yengxubevange enezinto zokugcina ezinjenge-zinc, i-hot-dip galvanizing, i-black oxide, i-nickel, ne-Dacromet. Ubuningi obuguquguqukayo boku-oda kanye nentengo yaseShayina encintisanayo kuyenza isebenze kubo bobabili abasabalalisi abaseke basungulwa kanye nemikhiqizo ekhulayo.

Qala ngokubuyekeza uhla lwemikhiqizo, bese ucela amasampula, ikhathalogi, kanye nesilinganiso sentengo yezinhlobo zezikulufu ozidingayo. Izinto ezijwayelekile zihlanganisa izikulufu ezizihlaba ngokwazo, ezizihlaba ngokwazo, ezomshini, ezokhuni, ze-drywall, zikakhonkolo, zethusi, kanye nezikulufu zensimbi engagqwali. Ithimba bese liqinisekisa imininingwane, ukupakisha, isikhathi sokuhola, kanye nemigomo yokuthumela ngokubhaliwe ngaphambi kokuba ukukhiqiza kuqale, ukuze kungabi khona okungalindelekile ekulethweni.
