Kukurumidza kusimukira kweindasitiri yemotokari yeChina kwakasimudzira kusimukira kweindastiri yekufa-casting.Ningbo Beilun anonakidzwa nemukurumbira we "guta rekumusha rekukanda kufa muChina".Pamusoro pekupa mudzimba Volkswagen, FAW, Chang'an, Chery, Geely, Great Wall, Chunlan, Midea nemamwe mabhizinesi, zvigadzirwa zvayo zvinopawo molds kuMercedes Benz, Volkswagen, Audi, Siemens, Ford, General Motors, Mazda nemamwe. mabhizinesi ane mukurumbira pasi rose.Iyo dhizaini uye nhanho yekugadzira, kugona kwekugadzira uye bhizinesi rekugadzira density ye die casting molds iri munzvimbo inotungamira muChina.
Muna 2007, kukosha kwekugadzirwa kweBeilun molds kwakasvika 2.8 bhiriyoni yuan, nekutengesa kunze kwakasvika 300 miriyoni yuan.Mari yekutengeswa kwezvikamu zvekufa-kanda yaive 2.6 bhiriyoni yuan, nekutengesa kunze kwakasvika 420 miriyoni yuan.
1. Nzvimbo yeBeilun die-casting molds munyika
Indasitiri yeBeilun mold yakatanga muna 1960s uye yakakurumidza kukura muma1990, ichitarisa pakufa-casting molds.Mushure memakore anopfuura makumi maviri ebudiriro, yakagadzira akati wandei mabhizinesi anobatsira ane hunhu hwakasiyana, uye yakavaka manomwe maneja epamusoro-tech mabhizinesi uye maviri epurovhinzi Enterprise engineering engineering tekinoroji nzvimbo muindasitiri yekuumbwa.Kune 34 kufa-casting mold mabhizinesi ane mold inobuda kukosha inopfuura mamirioni gumi yuan.
1.1 Key die-casting mold mabhizinesi
Kubva muna Ndira 1, 2006 kusvika Zvita 31, 2008, nyika yakashandisa nzira yekutanga kuunganidza mutero-yakawedzerwa mutero maererano nemirairo pane zvigadzirwa zveforoma zvinogadzirwa uye zvinotengeswa ne230 key mold Enterprises, uyezve kudzorera 50% yeiyo chaiyo kukosha-yakawedzerwa. mutero wakabhadharwa.Mutero wakadzoserwa wakanyatso shandiswa kushandurudza tekinoroji, kuchengetedza kwezvakatipoteredza, kuchengetedza simba uye kuderedzwa kwekushandisa kwemabhizinesi, uye kutsvagisa nekusimudzira zvigadzirwa zve mold.Pakati pemakambani makumi manomwe ari mudunhu reZhejiang, Ningbo anoverengera makumi mashanu, nepo Beilun aine gumi nemashanu (14 anonyanya kutarisisa zviumbwa zvinofa).
1.2 Beilun Die Casting Industry Chain
Nekuda kwehukama hwepedyo pakati pekugadzira mold uye kugadzira uye nekumusoro mold zvinhu zvekupa, kupisa kurapwa, kugadzira, mold standard zvikamu, uye yakadzika mold kugadzirisa zvikamu / zvigadzirwa (zvikamu zvepurasitiki, die-casting parts, etc.), mazhinji mold mabhizinesi ane zvese mold uye zvigadzirwa.Naizvozvo, iyo mold indasitiri cheni yakakamurwa kuita zvikamu zvitatu: "kumusoro kutsigira mabhizinesi", "mold dhizaini uye mabhizinesi ekugadzira", uye "kudzika kwakadzika mabhizinesi ekuwedzera".
1.2.1 Mabhizinesi anotsigira kumusoro
Kune anopfuura zana nemakumi mashanu ekuumbwa kwezvinhu zvekushandisa, kupisa kupisa, kufambisa simbi, uye mamwe mabhizinesi anotsigira ane chekuita nekugadzira mold uye kugadzira, ane vanopfuura zviuru zvishanu vashandi.
1.2.2 Mold dhizaini uye mabhizinesi ekugadzira
Kune huwandu hwemabhizinesi e1372 mold muBeilun, akabatana zvakananga mukugadzira mold uye mold zvikamu kugadzirisa, nevashandi vanopfuura 16000.
(1) Nhamba dzemabhizinesi ekuumbwa zvinoenderana nekugoverwa kwedunhu
Inenge 70% yekugoverwa kwedunhu kwemabhizinesi emuvhu muBeilun yakatarisana muDaqi, ichiteverwa neXiapu accounting ye11.37%.Kusungwa kwedunhu "unhu hweBeilun mold mabhizinesi.
(2) Kurongwa kunoenderana nemhando yekunyoresa bhizinesi
Zvinoenderana nehuwandu hweBeilun Mold Enterprises nerudzi rwebhizinesi, pakati pemabhizinesi e372 mold, mabhizinesi epamba anoita 96%.Mabhizinesi akazvimirira anoita basa rinotungamira "ndihwo humwe hunhu hweBeilun mold mabhizinesi.
(3) Kurongwa nemhando yeforoma
Marudzi makuru ezviumbwa muBeilun maforomo ekukanda-fa uye mold epurasitiki, nemamwe mabhizinesi ane zvese.Zviumbwa zvinofa zvinotora 75% kusvika 80%, zviumbwa zvepurasitiki zvinotora 15% kusvika 20%, uye zvimwe zviumbwa zvinotora 5% kusvika 8%.
1.2.3 Downstream ekuwedzera mabhizinesi
Yakachinjirwa kurudzi rwekuumbwa, mabhizinesi ekuwedzera epasi anonyanya kutarisa kufa, zvikamu zvepurasitiki, zvikamu zverabha, uye zvidhindo zvikamu.Semuyenzaniso, muBeilun Daqi, uko kugadzirwa kwe-die-casting kwakanangidzirwa, indasitiri yekugadzira-kufa-kasira yakagadzira kubva muindasitiri yekugadzira mold.Daqi ine anopfuura makumi matanhatu ekufa-casting mabhizinesi ekugadzira, anopfuura mazana mana ekufa-casting michina yemhando dzakasiyana-siyana, ine zvirevo kubva pa1250 kN kusvika 25000 kN.Kune anopfuura zana nemakumi mashanu emabhizinesi ekuwedzera epasi muBeilun.
1.3 Chikamu cheBeilun die-casting mold kukosha kwekugadzira munyika
Zvinoenderana nezviyero zvepasirese, mold dzakakamurwa kuita zvikamu gumi, nekutsikirira mold uye epurasitiki mold zviri izvo zvakanyanya zvigadzirwa muChina.Nekuvandudzwa kwemaindasitiri emotokari uye emidhudhudhu mumakore achangopfuura, chikamu chepurasitiki molds uye kufa-casting molds chave kuwedzera gore negore.Sekureva kwehuwandu hweChina Mold Association, muna 2001, zvidhinha zviumbwa zvakaverengera makumi mashanu muzana echigadzirwa chechigadzirwa cheChina, molds dzepurasitiki dzakaita 34%, kufa-casting molds inosvika 6%, uye mamwe marudzi emamold akaverengerwa. pamusoro pe10%;Nekukurumidza kusimudzira kwemaindasitiri emudhudhudhu, emota, uye emidziyo yemumba, indasitiri yekufa-kandira yakasimukira nekukurumidza, uye kukosha kwekubuda kwemafa-casting molds kwawedzera.Maererano nenhamba muna 2003, ma-molds e-die-casting ndeechipiri chete kune punch molds uye molds epurasitiki maererano nekugadzirwa uye huwandu, hunoita 8% yehuwandu hwekugadzirwa kwemhando dzakasiyana-siyana dzehutu;Neindasitiri yemotokari ichiva imwe yemaindasitiri embiru muChina uye budiriro yezvigadzirwa zvisingaremi, zvakasvibira, uye zvinochengetedza simba, kugadzirwa kweasiri-ferrous metal die-casting parts and molds kwakawedzera zvakanyanya.Zvinoenderana nesampling statistics yemafekitori enyika anofa-casting muna 2006, kukosha kwekubuda kwemafa-casting molds kuChina kwakaverengera gumi muzana yehuwandu hwehuwandu hwekubuda kweindasitiri yekuumbwa.
Chikamu chimwe chete muzvina chehuwandu hwehuwandu hwekubuda kwenyika kufa-casting molds inobva kuBeilun die-casting mold enterprises, iyo inoratidzawo chinzvimbo chakakosha cheindasitiri yeBeilun mold munyika.
2. Yazvino mamiriro eBeilun die-casting mold tekinoroji
Parizvino, mabhizinesi ekumusana mold muBeilun akashandisa tekinoroji yeCAD/CAM mukugadzira nekugadzira maitiro, uye mamwe acho anowedzerwawo neCAE yekugadzira simulation ongororo.Munguva yekugadzira, simbi yepamusoro-yepamusoro-inodzivirira kupisa H13 yakave sarudzo huru yesimbi.Vacuum quenching, kunyatsogadzira machining mushure mekudzima, kuungana uye kugadzirisa pamushini wekuvhara mold, uye kuyedza pamatatu ekuyeresa chiridzwa zvave zvakajairika maitiro akakosha uye nzira.Panyaya yevashandi vehunyanzvi hwemabhizinesi, kune vanopfuura mazana mashanu mainjiniya, uye mamwe makambani akaunzawo nyanzvi dzekunze kubva kuGermany, Japan, neSouth Korea kutungamira dhizaini nekugadzira mold.Panguva imwecheteyo, maindasitiri anotsigira akadai sekurapa kupisa uye kugadzirisa kwekugadzira muBeilun akawanawo kumwe budiriro.
2.1 Dhizaini Technology
Mold CAD/CAE/CAM tekinoroji yakakosha yekushandura dhizaini yechinyakare mold uye nzira dzekugadzira, zvichiita kuti nyanzvi dzeinjiniya dzishandise makomputa kugadzira uye kukwenenzvera kuita kwechigadzirwa, mold chimiro, kuumba maitiro, uye CNC machining.Izvi zvinogona kupfupisa zvakanyanya dhizaini yekugadzira uye kutenderera kwekugadzira, kuderedza mutengo wekugadzira, uye kugadzirisa mhando yechigadzirwa.
Mazhinji mabhizinesi muBeilun akashandisa zvakanyanya tekinoroji yeCAD/CAM mukugadzira mold, uye zvishoma nezvishoma akachinja kubva kune maviri-dimensional dhizaini kuenda kune matatu-dimensional dhizaini.Iyo yakasanganiswa yekugadzira tekinoroji inosanganisa matatu-dimensional modelling dhizaini uye CNC muchina maturusi yakasimudzirwa zvishoma nezvishoma, uye iyo digitization maitiro ekugadzira mold yakakwira.Mabhizinesi ekugadzira mold pamusoro pehukuru hwakatarwa akagadzira yakatsaurirwa 2D uye 3D mold dhizaini madhipatimendi uye akatengwa.
Ruzivo rwuri pamusoro rwunobva muraibhurari yejenari.Kuti uwane mamwe anofa-anokanda mold, ndapota teerera kune Fenda Mold.
