Kukula mwachangu kwamakampani opanga magalimoto ku China kwalimbikitsa chitukuko chamakampani opanga magalimoto.Ningbo Beilun amasangalala ndi mbiri ya "mzinda wakwawo wa nkhungu zakufa ku China".Kuphatikiza pa kupereka zoweta Volkswagen, FAW, Chang'an, Chery, Geely, Great Wall, Chunlan, Midea ndi mabizinesi ena, mankhwala ake amapereka nkhungu kuti Mercedes Benz, Volkswagen, Audi, Siemens, Ford, General Motors, Mazda ndi zina. makampani odziwika padziko lonse lapansi.Mapangidwe ndi kupanga, mphamvu zopangira ndi kachulukidwe kamakampani a nkhungu zoponya kufa ndizotsogola ku China.
Mu 2007, mtengo wa nkhungu za Beilun udafika pa 2.8 biliyoni, ndipo zotumiza kunja zidafika yuan miliyoni 300.Ndalama zogulitsa za zida zoponyera zida zakufa zinali 2.6 biliyoni ya yuan, ndipo zotumiza kunja zidafika yuan 420 miliyoni.
1. Udindo wa Beilun kufa-casting nkhungu m'dziko
Makampani opanga nkhungu ku Beilun adayamba mzaka za m'ma 1960s ndipo adakula mwachangu m'ma 1990, ndikuwunika zomwe zimafa.Pambuyo pazaka zopitilira 20 zachitukuko, zapanga mabizinesi angapo opindulitsa okhala ndi mikhalidwe yosiyana, ndikumanga mabizinesi asanu ndi awiri aukadaulo apamwamba komanso malo awiri am'chigawo cha Enterprise engineering engineering mumakampani a nkhungu.Pali mabizinesi 34 oponya nkhungu omwe ali ndi mtengo wotulutsa wopitilira yuan miliyoni 10.
1.1 Mabizinesi akuluakulu oponya nkhungu
Kuyambira pa Januware 1, 2006 mpaka Disembala 31, 2008, boma lidakhazikitsa njira yoyamba yotolera msonkho wowonjezera mtengo molingana ndi malamulo azinthu zopangidwa ndi nkhungu zomwe zimapangidwa ndikugulitsidwa ndi mabizinesi 230 ofunikira, ndikubweza 50% ya mtengo weniweniwo. msonkho woperekedwa.Misonkho yobwezeredwayo idagwiritsidwa ntchito makamaka pakusintha kwaukadaulo, kuteteza chilengedwe, kusunga mphamvu ndi kuchepetsa mabizinesi, komanso kafukufuku ndi chitukuko cha zinthu za nkhungu.Mwa makampani 70 m'chigawo cha Zhejiang, Ningbo ali ndi 50, pomwe Beilun ali ndi 15 (14 makamaka amangoyang'ana nkhungu zoponya kufa).
1.2 Beilun Die Casting Viwanda Chain
Chifukwa cha ubale wapakatikati wa kapangidwe ka nkhungu ndi njira zopangira ndi kumtunda kwa zinthu zopangira nkhungu, chithandizo cha kutentha, kupangira zida, magawo a nkhungu, ndi zida zopangira nkhungu / zinthu (zigawo zapulasitiki, zida zoponyera, etc.), mabizinesi a nkhungu ali ndi nkhungu ndi zinthu zonse.Chifukwa chake, makampani opanga nkhungu amagawidwa m'magawo atatu: "mabizinesi othandizira kumtunda", "mabizinesi opangira nkhungu ndi kupanga", ndi "mabizinesi owonjezera otsika".
1.2.1 Mabizinesi othandizira kumtunda
Pali zinthu zopitilira 150 zomwe zimaperekedwa ndi nkhungu, chithandizo cha kutentha, zopangira, ndi mabizinesi ena othandizira okhudzana ndi kapangidwe ka nkhungu ndi kupanga, okhala ndi antchito opitilira 5000.
1.2.2 Mapangidwe a nkhungu ndi kupanga mabizinesi
Pali okwana mabizinesi nkhungu 1372 ku Beilun, mwachindunji chinkhoswe ndi nkhungu mbali processing, ndi antchito pa 16000.
(1) Ziwerengero zamakampani a nkhungu zochokera kugawa kwachigawo
Pafupifupi 70% ya kugawa kwamabizinesi a nkhungu ku Beilun kumakhazikika ku Daqi, kutsatiridwa ndi Xiapu kuwerengera 11.37%.Chigawo chachigawo "ndi chikhalidwe cha mabizinesi a Beilun mold.
(2) Gulu kutengera mtundu wa kulembetsa mabizinesi
Malinga ndi ziwerengero za Beilun Mold Enterprises ndi mtundu wamabizinesi, pakati pa mabizinesi a nkhungu 372, mabizinesi apakhomo amakhala 96%.Mabizinesi wamba amatenga gawo lotsogola "ndi chikhalidwe china chamakampani a Beilun mold.
(3) Gulu ndi mtundu wa nkhungu
Mitundu yayikulu ya nkhungu ku Beilun ndi nkhungu zoponya kufa ndi pulasitiki, mabizinesi ena ali ndi zonse ziwiri.75% mpaka 80% ya nkhungu zomwe zimafa zimayambira, 15% mpaka 20% ya nkhungu za pulasitiki, ndipo zina zimatengera 5% mpaka 8%.
1.2.3 Mabizinesi owonjezera otsika
Zogwirizana ndi mtundu wa nkhungu, mabizinesi owonjezera otsika kwambiri amayang'ana kwambiri pazigawo zakufa, zida zapulasitiki, zida za mphira, ndi zida zopondaponda.Mwachitsanzo, ku Beilun Daqi, komwe kumapanga makina opangira zida zakufa, makampani opanga zinthu zakufa ayamba kuchokera kumakampani opanga nkhungu.Daqi ili ndi mabizinesi opitilira 60 oponya ma kufa, makina opitilira 400 amitundu yosiyanasiyana, okhala ndi mawonekedwe kuyambira 1250 kN mpaka 25000 kN.Pali mabizinesi opitilira 150 otsika ku Beilun.
1.3 Gawo la mtengo wopanga nkhungu wa Beilun kufa mdziko muno
Malinga ndi miyezo ya dziko, nkhungu zimagawidwa m'magulu khumi, ndi nkhungu zopondaponda ndi pulasitiki zomwe zimakhala zinthu zazikulu ku China.Ndi chitukuko cha mafakitale opangira magalimoto ndi njinga zamoto m'zaka zaposachedwa, gawo la nkhungu zapulasitiki ndi nkhungu zoponyera kufa zakhala zikuwonjezeka chaka ndi chaka.Malinga ndi ziwerengero za China Nkhungu Association, mu 2001, 2001, mitundu 50% ya zinthu zopangidwa ndi nkhungu zaku China, nkhungu za pulasitiki zimakhala pafupifupi 34%, nkhungu zoponyera zimawerengera pafupifupi 6%, ndi mitundu ina ya nkhungu. pafupifupi 10%;Ndikukula kwachangu kwa mafakitale anjinga zamoto, magalimoto, ndi zida zapakhomo, makampani opanga zida zakufa akula mwachangu, ndipo mtengo wotuluka wa nkhungu zoponya kufa wakula.Malinga ndi ziwerengero mu 2003, nkhungu kufa-ponyera ndi wachiwiri kwa nkhonya zisamere pachakudya ndi zisamere pachakudya pulasitiki mu mawu a kupanga ndi kuchuluka, mlandu pafupifupi 8% ya okwana kupanga mitundu yosiyanasiyana ya nkhungu;Ndi makampani opanga magalimoto kukhala imodzi mwamafakitale apamwamba ku China ndi chitukuko cha zinthu zopepuka, zobiriwira, komanso zopulumutsa mphamvu, kupanga zida zoponyera zitsulo zopanda chitsulo ndi nkhungu zakula kwambiri.Malinga ndi ziwerengero zamafakitale opangira zida zamtundu wakufa mu 2006, mtengo wotulutsa nkhungu ku China wapanga 10% ya kuchuluka kwamakampani opanga nkhungu.
Gawo limodzi mwa magawo atatu aliwonse amtengo wapatali wa nkhungu zoponyera dziko lapansi zimachokera ku mabizinesi a Beilun kufa-casting mold, omwe akuwonetsanso udindo wofunikira wamakampani opanga nkhungu ku Beilun mdziko muno.
2. Mkhalidwe wamakono waukadaulo wa nkhungu wa Beilun kufa-casting
Pakalipano, mabizinesi amtundu wa msana ku Beilun agwiritsa ntchito ukadaulo wa CAD/CAM pakupanga ndi kupanga, ndipo ena mwa iwo amathandizidwanso ndi CAE popanga kusanthula koyerekeza.Panthawi yokonza, zitsulo zapamwamba kwambiri zosagwira kutentha H13 zakhala chisankho chachikulu chachitsulo.Kuzimitsa vacuum, kukonza mwatsatanetsatane pambuyo kuzimitsa, kusonkhanitsa ndi kukonza zolakwika pamakina otsekera nkhungu, komanso kuyesa pazida zitatu zoyezera zomwe zakhala zikuchitika zakhala njira zodziwika bwino.Pankhani ya ogwira ntchito zamabizinesi, pali mainjiniya akuluakulu opitilira 500, ndipo makampani ena abweretsanso akatswiri akunja ochokera ku Germany, Japan, ndi South Korea kuti aziwongolera kapangidwe ka nkhungu ndi kupanga.Nthawi yomweyo, mafakitale othandizira monga chithandizo cha kutentha ndi kukonza makina ku Beilun apezanso chitukuko china.
2.1 Design Technology
Mould CAD/CAE/CAM ndi ukadaulo wofunikira kwambiri wosinthira mapangidwe azikhalidwe za nkhungu ndi njira zopangira, zomwe zimathandiza akatswiri a uinjiniya kugwiritsa ntchito makompyuta kupanga ndi kukonza magwiridwe antchito azinthu, kapangidwe ka nkhungu, kupanga njira, ndi makina a CNC.Izi zitha kufupikitsa kamangidwe ka nkhungu ndi kuzungulira kwa kupanga, kuchepetsa ndalama zopangira, komanso kukonza zinthu.
Mabizinesi ambiri ku Beilun agwiritsa ntchito ukadaulo wa CAD/CAM popanga nkhungu, ndipo pang'onopang'ono asintha kuchoka pakupanga mawonekedwe amitundu iwiri kupita kumitundu itatu.Ukadaulo wophatikizika wophatikizira wophatikiza mawonekedwe amitundu itatu ndi zida zamakina a CNC walimbikitsidwa pang'onopang'ono, ndipo njira ya digito yopanga nkhungu ndiyokwera kwambiri.Makampani opanga nkhungu pamwamba pa kukula kwake akhazikitsa madipatimenti odzipatulira a 2D ndi 3D mold ndikugula.
Zomwe zili pamwambazi zikuchokera ku library library.Kuti mumve zambiri, chonde tcherani khutu ku Fenda Mold.
