Ukukhangela othembekileyo Umzi-mveliso we-European Investment Casting Federation—kodwa ukufumana uninzi lwamalungu adweliswe eJamani, eItali, okanye ePoland? AWUKHO wedwa. Abathengi abaninzi behlabathi bacinga ukuba i-European Investment Casting Federation (EICF) ulawulo luquka kuphela i-EU-based foundries. Enyanisweni, luphawu—kungekhona umda. I-EICF ibeka imigangatho yobugcisa, umgangatho, kunye nemo engqongileyo esetyenziswa kwihlabathi jikelele. Kwaye ngokwandayo, abavelisi abangaphandle kweYurophu-ingakumbi abo baqinisekisiweyo kwi-ISO 9001, ISO 14001, kunye ne-AS9100-babhekiselwa kwiinjineli ezihlangene ne-EICF njengamahlakani afanelekileyo kwi-high-integrity investment castings.
Elinye iqabane elinjalo QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ikomkhulu eQingdao, eTshayina. Sisebenze kunye neqela labo kwiinkqubo zezindlu zempompo ezintathu ezahlukeneyo kwiinyanga ezidlulileyo ze-24-ezimbini kwii-OEM ze-hydraulic eSweden, enye ye-subsea valve supplier eNorway. Eyona nto yayigqamileyo yayingekokuthobela nje iinkcukacha ezihambelana ne-EICF ezifana ne-EN 1559-3 okanye i-ASTM A958, kodwa indlela abazifakela ngayo ezo mfuno kufezekiso lwemihla ngemihla: umkhondo wemathiriyeli ukuya kwinani lobushushu, ixesha lokwenyani lengxelo ye-CMM ye-loops ngexesha lomatshini, kunye nokunyamezelwa kwe-zero kwi-dimensional drift kwi-500-piece-piece.
Amandla abo alele ekwazini izinto ezininzi eziziphephayo: ii-cobalt-nickel superalloys phantsi kolawulo oluqinileyo lwe-GD&T. Ngokukodwa, i-AMS 5387 i-cobalt alloy 6 kunye ne-T800-grade materials-zombini zidume ngokuqiniswa komsebenzi, ukuphazamiseka kwe-thermal, kunye novelwano lwe-microcrack ngexesha lokuphosa kunye nokugqiba-machining. Siye sabona iivenkile zala iiodolo ze-AMS 5387 ngokuthe ngqo. I-QINGDAO QIANGSENYUAN ayizaleli. Bafanelekela kwangaphambili yonke inyibiliko kunye nokuqinisekiswa kwe-spectrographic, baqhube ukulinganisa ukuqina phambi koyilo lokubumba, kwaye babambe iindawo zokugqibela kwisigxina esilawulwa yimozulu kwiiyure ze-72 ngaphambi kokuhlolwa-ukubamba iinguqu ezishiyekileyo zoxinzelelo ezinokuthi zigqithise iitshekhi zokuqala.
Ukudityaniswa okuthe nkqo kwenza umahluko. Uninzi "lweefektri zokuphosa utyalo-mali" lwangaphandle lwe-CNC lugqibezela-okanye okubi ngakumbi, luxhomekeke kubaphathi bobushushu bomntu wesithathu. I-QINGDAO QIANGSENYUAN ingumnikazi wawo onke amanyathelo abalulekileyo: ukwakhiwa kweqokobhe lotyalo-mali, ukugalelwa kwe-vacuum-assisted, i-multi-axis CNC machining (ukuya kuthi ga kwi-5-axis ngaxeshanye), ukuxutywa kwesisombululo, kunye nonyango oluphezulu olufana ne-HVOF yokugquma imilomo ye-cobalt. Olu ayilolawulo lwethiyori. Kuthetha ukuba izindlu zepiston pump cylinder zifika kunye ≤± 0.015 mm ubukhulu bodonga oluguquguqukayo kwi-320 mm yeedayamitha-kunye nokulandeleka okugcweleyo kweqashiso elidibanisa inxalenye nganye kumthi wayo wokuqala wokuphosa, ilog yesithando somlilo, kunye nefayile yendlela yesixhobo.
Nantsi into abathengi abayibuza ngokwenene-kwaye sibaxelela ntoni:
- "Ngaba bayakwazi ukuphatha iijiyometri ezingekho mgangathweni?" Ewe-ukuba ijometri isebenza umsebenzi. Abaleqeki ukuntsonkotha ngenxa yabo. Iqela labo lobunjineli libonisa iimpawu ezongeza iindleko ngaphandle kokufumana umsebenzi: iimbambo ezinqabileyo ezingafunekiyo, imingxuma eyimfama enzulu kuno-4 × ububanzi, okanye i-radii encinci kuneyona nto ivumelayo. I-winch center shaft roller uyila ngokutsha ixesha lokusikwa komjikelo ngama-37% ngokuhlengahlengisa iradiyasi yefillet ukusuka kwi-R0.3 ukuya kwi-R0.8—ngaphandle kokuchaphazela ingqibelelo yendlela yomthwalo.
- "Kuthekani ngokuhambelana nokuhanjiswa?" Bazibophelela kwiifestile zeentsuku ezi-±-3-hayi "ngaphakathi kweeveki ezi-4-6." Oko kuvela kucwangciso olubhityileyo: akukho zilungiso ekwabelwana ngazo phakathi kwe-cobalt kunye namaqashiso angenastainless, iiseli ezinikezelweyo zezixhobo kusapho lwealloyi nganye, kunye nezithinteli zemathiriyeli ekrwada ezilungelelaniswe kumaxesha okukhokela ababoneleli-hayi nje umthamo wangaphakathi.
- "Ngaba bayayixhasa iprototyping?" Ngokuqinisekileyo-kodwa kuphela ngeenkqubo zenjongo yemveliso. Akukho prototypes yesanti-cast yemveliso yotyalo-mali oluqhutywayo. Akukho mockups aluminiyam kumacandelo cobalt. Isicatshulwa sabo seprototype siquka i-NDT epheleleyo, ingxelo ye-metallurgical, kunye novavanyo olusebenzayo ngokuchasene ne-spec yokugqibela-so ukuqinisekiswa kokudluliselwa kwedatha ngokuthe ngqo kwi-PPAP.
Ngaba QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ilungu le-EICF? Hayi-azikho ikomkhulu eYurophu. Kodwa ngaba ziphathwa njengokwandiswa kwe-de facto ye-EICF-grade isakhono ziinjineli zokuyila zaseYurophu? Ewe. Ngenxa yokuba ixabiso lokwenyani lomfelandawonye ayilobulungu-bubungqongqo obusemva komgangatho. Kwaye obo bunzima buhamba. Isetyenziswa eQingdao ngoqeqesho olufanayo olusetyenziswa eBrescia okanye eBochum.
Ukufumana amaqela okuthenga Umzi-mveliso we-European Investment Casting Federation-inqanaba lokuchaneka-ingakumbi kwiivalvu zoxinzelelo, iindibano zempompo, okanye izixhobo ze-oyile negesi ezifuna i-AMS 5387, T800, okanye izisombululo ze-cobalt-nickel yesiko-umbuzo awukho "Iphi i-Foundry?" Ithi "Ihlala phi inkqubo yoqeqesho?" Olo qeqesho luhlala apho inzululwazi yezinto eziphathekayo idibana ngokuchanekileyo koomatshini-kwaye ngoku, ihlala eQingdao.
