Ufuna othembekile Ifekthri ye-European Investment Casting Federation—kodwa ukuthola amalungu amaningi asohlwini azinze eJalimane, e-Italy, noma ePoland? Awuwedwa. Abathengi abaningi bomhlaba wonke bacabanga ukuthi uhla lwemibhalo lwe-European Investment Casting Federation (EICF) luhlanganisa kuphela abasunguli abasekelwe e-EU. Empeleni, kuwuphawu—hhayi umngcele. I-EICF ibeka izindinganiso zobuchwepheshe, zekhwalithi, nezemvelo ezisetshenziswa emhlabeni wonke. Futhi ngokwandayo, abakhiqizi abangaphandle kwe-Europe—ikakhulukazi labo abagunyazwe ku-ISO 9001, ISO 14001, kanye ne-AS9100—babhekiselwa kubo onjiniyela abasebenzisana ne-EICF njengabalingani abafanelekayo bokusakazwa kokutshalwa kwezimali kobuqotho obuphezulu.
Omunye umlingani onjalo QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., enekomkhulu eQingdao, eChina. Sisebenze nethimba labo ezinhlelweni ezintathu ezihlukene zezindlu zamaphampu ezinyangeni ezingama-24 ezedlule—ezimbili kuma-OEM asebenza ngogesi e-Sweden, eyodwa ngeyomhlinzeki wamavalvu angaphansi kolwandle eNorway. Okugqamile akukhona nje ukuthobela imininingwane ehambisana ne-EICF efana ne-EN 1559-3 noma i-ASTM A958, kodwa ukuthi bashumeke kanjani lezo zidingo ekusetshenzisweni kwansuku zonke: ukulandelelwa kwezinto ezibonakalayo kuze kufike kunombolo yokushisa, izihibe zempendulo ye-CMM yesikhathi sangempela ngesikhathi somshini, kanye nokungabekezeleli lutho kokudonswa kwe-dimensional kumaqoqo angama-500.
Amandla abo atholakala ekwazini lokho okugwenywa yizisekelo eziningi: ama-cobalt-nickel superalloy ngaphansi kokulawula okuqinile kwe-GD&T. Ngokukhethekile, i-AMS 5387 cobalt alloy 6 kanye ne-T800-grade materials—zombili ezaziwa ngokuqinisa umsebenzi, ukuhlanekezela okushisayo, nokuzwela kwe-microcrack ngesikhathi sokusakaza nokuqeda. Sibone izitolo zenqaba ama-oda e-AMS 5387 ngokuqondile. I-QINGDAO QIANGSENYUAN ayizenqabi. Bafanelekela kuqala ukuncibilika ngakunye ngokuqinisekiswa kwe-spectrographic, basebenzise ukulingisa kokuqinisa ngaphambi kokuklanywa kwesikhunta, futhi babambe izingxenye zokugcina endaweni elawulwa yisimo sezulu amahora angu-72 ngaphambi kokuhlolwa—ukubamba izinguquko ezinsalela zengcindezi ebezingadlula amasheke okuqala.
Ukuhlanganiswa okuqondile kwenza umehluko. “Amafekthri amaningi okutshala imali” akhipha i-CNC ekuqedeni—noma okubi nakakhulu, athembele kubahlambi bokushisa benkampani yangaphandle. I-QINGDAO QIANGSENYUAN ingumnikazi wazo zonke izinyathelo ezibucayi: ukwakha igobolondo le-investimenti, ukusakaza okusizwa ngevacuum, ukwenziwa kwemishini ye-CNC ye-axis eminingi (kufika ku-5-eksisi kanyekanye), ukufakwa kwesisombululo, nokwelashwa kwendawo okufana ne-HVOF yokumboza imibhobho ye-cobalt. Lokhu akukhona ukulawula kwethiyori. Kusho ukuthi izindlu zamasilinda epompo yepiston zifika ≤±0.015 mm ukujiya kodonga kumadayamitha angu-320 mm—kanye nokulandeleka okugcwele kwenkatho okuxhumanisa ingxenye ngayinye esihlahleni sayo sokuqala sokuphonswa, ilogi yesithando somlilo, nefayela lendlela yamathuluzi.
Nakhu okubuzwa ngabathengi—nokuthi sibatshelani:
- "Bangakwazi ukuphatha amajiyometri angajwayelekile?" Yebo-uma i-geometry isebenza umsebenzi. Abajahi inkimbinkimbi ngenxa yayo. Ithimba labo lonjiniyela lihlaba umkhosi izici ezengeza izindleko ngaphandle kwenzuzo yokusebenza: izimbambo ezincane ezingadingekile, izimbobo eziyizimpumputhe ezijule kunobubanzi obungu-4×, noma irediya encane kunohlamvu olubonakalayo oluvumelayo. I-winch center shaft roller yokuklama kabusha isikhathi somjikelezo wokusika ngo-37% ngokumane ulungise i-fillet radius isuka ku-R0.3 iye ku-R0.8—ngaphandle kokuthinta ubuqotho bendlela yokulayisha.
- "Kuthiwani mayelana nokuvumelana kokulethwa?" Bazibophezela kumafasitela ezinsuku ezingu-±3—hhayi “phakathi kwamaviki ama-4–6.” Lokho kuvela ekuhleleni okuncane: akukho ukulungisa okwabelwana ngakho phakathi kwe-cobalt nenkatho engagqwali, amaseli amathuluzi azinikele emndenini wengxubevange, namabhafa wempahla eluhlaza aqondaniswe nezikhathi zokuhola zabahlinzeki—hhayi nje umthamo wangaphakathi.
- "Ingabe bayayisekela i-prototyping?" Impela—kodwa kuphela ngezinqubo zenhloso yokukhiqiza. Awekho ama-sand-cast prototypes okuqhuba ukukhiqizwa kokutshala imali. Awekho ama-aluminium mockups wezingxenye ze-cobalt. Isilinganiso sabo se-prototype quote sihlanganisa i-NDT ephelele, ukubika kwe-metallurgical, nokuhlolwa okusebenzayo ngokumelene ne-spec yokugcina-ngakho ukuqinisekiswa kwedatha kudluliswa ngokuqondile ku-PPAP.
Ingabe i-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ilungu le-EICF? Cha—azikho ikomkhulu eYurophu. Kodwa ingabe ziphathwa njengesandiso se-de facto samandla we-EICF-grade onjiniyela bokuklama baseYurophu? Yebo. Ngenxa yokuthi inani langempela lomfelandawonye akubona ubulungu—iwukuqina kwezindinganiso. Futhi lokho kuqina kuyahamba. Isetshenziswa e-Qingdao ngendlela efanayo esetshenziswa e-Brescia noma e-Bochum.
Okokuthola amaqembu okuthenga Ifekthri ye-European Investment Casting Federation-ukunemba kwezinga—ikakhulukazi amavalvu okucindezela, amaphampu, noma izingxenye zikawoyela negesi ezidinga i-AMS 5387, T800, noma izisombululo ze-cobalt-nickel zangokwezifiso—umbuzo awukona ukuthi “Ikuphi indawo yokusungula?” Ithi "Ihlala kuphi isiyalo senqubo?" Leso seluleko sihlala lapho isayensi yezinto ezibonakalayo ihlangabezana nokunemba komshini—futhi njengamanje, ihlala eQingdao.
