Ukuthuthuka okusheshayo kwemboni yezimoto yaseShayina kugqugquzele ukuthuthukiswa kwemboni yokukhiqiza izimoto.I-Ningbo Beilun ijabulela idumela "ledolobha lasekhaya le-die casting molds e-China".Ngaphezu kokuhlinzeka ngeVolkswagen yasekhaya, i-FAW, i-Chang'an, i-Chery, i-Geely, i-Great Wall, i-Chunlan, i-Midea namanye amabhizinisi, imikhiqizo yayo iphinde inikeze isikhunta kwaMercedes Benz, Volkswagen, Audi, Siemens, Ford, General Motors, Mazda nezinye. amabhizinisi adumile emhlabeni.Izinga lokuklama nelokukhiqiza, amandla okukhiqiza kanye nokuminyana kwebhizinisi lokukhiqiza lokubunjwa kwe-die casting kusendaweni ehamba phambili e-China.
Ngo-2007, inani lokukhiqizwa kwesikhunta se-Beilun lafinyelela kuma-yuan ayizigidi eziyizinkulungwane ezingu-2.8, ukuthunyelwa kwamanye amazwe kwafinyelela kuma-yuan ayizigidi ezingu-300.Imali etholwayo yokuthengisa yezingxenye ezisafufusa yayingama-yuan ayizigidi eziyizinkulungwane ezingama-2.6, ukuthunyelwa kwamanye amazwe kwafinyelela kumayuan ayizigidi ezingama-420.
1. Isikhundla se-Beilun die-casting molds ezweni
Imboni yesikhunta saseBeilun yaqala ngeminyaka yawo-1960s futhi yathuthuka ngokushesha ngeminyaka yawo-1990, igxile ekubumbeni okufayo.Ngemva kweminyaka engaphezu kwengu-20 yentuthuko, isisungule inqwaba yamabhizinisi anenzuzo anezici ezihlukile, futhi yakha amabhizinisi kamasipala ayisikhombisa zobuchwepheshe obuphezulu kanye nezikhungo ezimbili zezifundazwe zobuchwepheshe zobunjiniyela bobunjiniyela bebhizinisi embonini yokubumba.Kunamabhizinisi angama-34 akhiqiza isikhunta anenani lokukhipha isikhunta elingaphezu kwezigidi eziyi-10 zamayuan.
1.1 Amabhizinisi angukhiye akhiqiza isikhunta
Kusukela mhla lu-1 kuMasingana wezi-2006 kuya zingama-31 kuZibandlela wezi-2008, umbuso wasebenzisa indlela yokuqala yokuqoqa intela ye-value-added ngokwemithetho yemikhiqizo yesikhunta ekhiqizwa futhi idayiswe amabhizinisi angukhiye angu-230, bese ubuyisela u-50% yenani langempela elengeziwe. intela ikhokhwe.Intela ebuyisiwe yasetshenziselwa ukuguqulwa kwezobuchwepheshe, ukuvikelwa kwemvelo, ukongiwa kwamandla kanye nokunciphisa ukusetshenziswa kwamabhizinisi, kanye nokucwaninga nokuthuthukiswa kwemikhiqizo yesikhunta.Phakathi kwezinkampani ezingu-70 esifundazweni saseZhejiang, i-Ningbo yenza ezingu-50, kanti i-Beilun inezingu-15 (eziyi-14 ikakhulukazi ezigxile ekubunjweni kwe-die-casting).
1.2 I-Beilun Die Casting Industry Chain
Ngenxa yobudlelwano obuseduze phakathi komklamo wesikhunta kanye nenqubo yokukhiqiza kanye nokuhlinzekwa kwempahla yesikhunta ekhuphukayo, ukwelashwa kokushisa, ukunikezwa kwe-forging, izingxenye ezijwayelekile zokubumba, nezingxenye/imikhiqizo yokucubungula isikhunta (izingxenye zepulasitiki, izingxenye ezifayo, njll.), eziningi amabhizinisi esikhunta anakho kokubili isikhunta nemikhiqizo.Ngakho-ke, uchungechunge lwezimboni zesikhunta luhlukaniswe izingxenye ezintathu: "amabhizinisi asekelayo akhuphuka nomfula", "i-mold design kanye namabhizinisi okukhiqiza", kanye "namabhizinisi anwebekayo".
1.2.1 Amabhizinisi asekelayo akhuphukayo
Kukhona izinto ezisetshenziswayo zokubumba ezingaphezu kwe-150, ukwelashwa kokushisa, ukuhlinzekwa kwe-forging, namanye amabhizinisi asekelayo ahlobene nokwakhiwa kwesikhunta nokukhiqiza, nabasebenzi abangaphezu kuka-5000.
1.2.2 Amabhizinisi aklama isikhunta kanye nokukhiqiza
Kunamabhizinisi esikhunta ayi-1372 e-Beilun, asebenza ngokuqondile ekucubunguleni izingxenye zesikhunta kanye nesikhunta, anabasebenzi abangaphezu kuka-16000.
(1) Izibalo zamabhizinisi esikhunta ezisekelwe ekusabalaliseni kwesifunda
Cishe i-70% yokusatshalaliswa kwesifunda kwamabhizinisi esikhunta e-Beilun kugxile e-Daqi, kulandelwa i-Xiapu accounting ye-11.37%.Ukuhlushwa kwesifunda “kuyisici samabhizinisi e-Beilun mold.
(2) Ukuhlelwa okusekelwe kuhlobo lokubhaliswa kwebhizinisi
Ngokwezibalo zeBeilun Mold Enterprises ngohlobo lwebhizinisi, phakathi kwamabhizinisi esikhunta angama-372, amabhizinisi asekhaya enza ama-96%.Amabhizinisi azimele adlala indima eholayo "ngesinye isici samabhizinisi e-Beilun mold.
(3) Ukuhlukaniswa ngohlobo lwesikhunta
Izinhlobo eziyinhloko zokubunjwa e-Beilun yizibungu ezilahlayo kanye nezibunjwa zepulasitiki, kanti amanye amabhizinisi anakho kokubili.Isikhunta se-die-casting senza u-75% kuya ku-80%, isikhunta sepulasitiki singu-15% kuya ku-20%, kanti ezinye isikhunta zenza u-5% kuya ku-8%.
1.2.3 Amabhizinisi okunweba aphansi komfula
Kujwayelane nohlobo lwesikhunta, amabhizinisi anwebekayo abheke ezansi nomfula agxile kakhulu ekulingiseni ukufa, izingxenye zepulasitiki, izingxenye zenjoloba, nezingxenye zokugxiviza.Isibonelo, e-Beilun Daqi, lapho ukukhiqizwa kwe-die-casting kugxilwe khona, imboni yokukhiqiza i-die-casting iye yathuthuka kusukela embonini yokukhiqiza isikhunta.I-Daqi inamabhizinisi okukhiqiza ama-die-cast angaphezu kuka-60, imishini yokukhipha ukufa engaphezu kuka-400 yezinhlobo ezihlukahlukene, enemininingwane esukela ku-1250 kN kuya ku-25000 kN.Kunamabhizinisi angaphezu kwe-150 ezansi nomfula e-Beilun.
1.3 Ingxenye yenani lokukhiqiza isikhunta se-Beilun ezweni
Ngokwezindinganiso zikazwelonke, isikhunta sihlukaniswe izigaba eziyishumi, lapho ukubumba okugxiviza kanye nokubunjwa kwepulasitiki kuyimikhiqizo eyinhloko eChina.Ngokuthuthuka kwezimboni zezimoto nezithuthuthu eminyakeni yamuva nje, isabelo sesikhunta sepulasitiki kanye nesikhunta se-die-casting siye sanda unyaka nonyaka.Ngokwezibalo ze-China Mold Association, ngo-2001, isikhunta sokugxiviza sasibalelwa ku-50% wesakhiwo somkhiqizo waseChina, isikhunta sepulasitiki silinganiselwa ku-34%, isikhunta se-die-casting sabalelwa ku-6%, kanti ezinye izinhlobo zesikhunta zibalwe. cishe 10%;Ngokuthuthuka okusheshayo kwezimboni zezithuthuthu, zezimoto, kanye nemishini yasendlini, imboni ye-die-casting ithuthuke ngokushesha, futhi nenani lokuphumayo lesikhunta se-die-casting liye landa.Ngokwezibalo zango-2003, isikhunta se-die-casting singesesibili kuphela ukubunjwa kwe-punch kanye ne-plastic molds mayelana nokukhiqizwa kanye nobuningi, okulinganiselwa ku-8% wengqikithi yokukhiqizwa kwezinhlobo ezihlukahlukene zesikhunta;Njengoba imboni yezimoto isiba ngenye yezimboni eziyizinsika eShayina kanye nendlela yokuthuthukiswa kwemikhiqizo engasindi, eluhlaza, neyonga amandla, ukukhiqizwa kwezingxenye zokuphonsa zensimbi ezingenayo insimbi kanye nokubunjwa kuye kwanda kakhulu.Ngokwezibalo zesampula zamafekthri kazwelonke akhiqiza i-die-casting ngo-2006, inani lokukhishwa kwezibungu ezifayo eShayina libalele ku-10% yenani eliphelele lomkhiqizo wemboni yokubumba.
Ingxenye eyodwa kwezine yenani eliphelele lomkhiqizo wesikhunta sikazwelonke se-die-casting livela ezinkampanini ze-Beilun die-casting mold, futhi ezigqamisa isikhundla esibalulekile semboni yesikhunta sase-Beilun ezweni.
2. Isimo samanje sobuchwepheshe besikhunta se-Beilun die-casting
Njengamanje, amabhizinisi esikhunta esiwumgogodla e-Beilun asebenzise ubuchwepheshe be-CAD/CAM enqubweni yokuklama neyokukhiqiza, kanti amanye awo abuye alekelelwa yi-CAE ukuze enze ukuhlaziya kokulingisa.Phakathi nenqubo yokucubungula, insimbi yezinga eliphezulu engavimbeli ukushisa i-H13 isibe yisinqumo esiyinhloko sensimbi.Ukucisha i-vacuum, ukukhanda imishini ngokunemba ngemva kokucisha, ukuhlanganisa nokulungisa iphutha emshinini wokuvala isikhunta, nokuhlola ithuluzi lokulinganisa lezixhumanisi ezintathu sekuyizinqubo nezindlela eziyinhloko ezivamile.Mayelana nabasebenzi bezobuchwepheshe bebhizinisi, kunonjiniyela abaphezulu abangaphezu kuka-500, futhi ezinye izinkampani zethule nochwepheshe bangaphandle abavela eJalimane, eJapane, naseNingizimu Korea ukuze baqondise ukwakheka nokukhiqizwa kwesikhunta.Ngasikhathi sinye, izimboni ezisekelayo ezinjengokwelashwa kokushisa kanye nokucubungula kwe-forging e-Beilun nazo zithole intuthuko ethile.
2.1 Ubuchwepheshe Bokuklama
I-Mold CAD/CAE/CAM iwubuchwepheshe obubalulekile bokuguqula ukwakheka kwesikhunta sendabuko nezindlela zokukhiqiza, okwenza ochwepheshe bonjiniyela basebenzise amakhompiyutha ukuze baklame futhi bathuthukise ukusebenza komkhiqizo, ukwakheka kwesikhunta, inqubo yokwenza, kanye nemishini ye-CNC.Lokhu kunganciphisa kakhulu ukwakheka kwesikhunta nomjikelezo wokukhiqiza, kwehlise izindleko zokukhiqiza, futhi kuthuthukise ikhwalithi yomkhiqizo.
Amabhizinisi amaningi e-Beilun asebenzise kabanzi ubuchwepheshe be-CAD/CAM enqubweni yokukhiqiza isikhunta, futhi kancane kancane aguquke esuka ekwakhiweni okunezinhlangothi ezimbili kuya ekwakhiweni kwezinhlangothi ezintathu.Ubuchwepheshe obudidiyelwe bokukhiqiza obuhlanganisa ukwakheka kokumodela okunezinhlangothi ezintathu kanye namathuluzi omshini we-CNC buye bakhuthazwa kancane kancane, futhi inqubo yokwenza idijithali yokukhiqiza isikhunta iphakeme kakhulu.Amabhizinisi akhiqiza isikhunta ngaphezu kobukhulu obunqunyiwe asungule iminyango yokuklama isikhunta eyi-2D ne-3D futhi athengiwe.
Ulwazi olungenhla luvela kumtapo wolwazi wejenali.Ukuze uthole ezinye isikhunta esibulalayo, sicela unake i-Fenda Mold.
