Lapho onjiniyela bayacacisa ukunemba okuphezulu kwe-magnesium alloy die casting factory, abaceli umphakeli nje kuphela—bafuna ukuzinza kohlangothi ngaphansi kwamabhayisikili ashisayo, ukufana kwesakhiwo esincane kuzo zonke izigaba ezinezindonga ezincane, kanye nokungabi sengozini kwamandla aqinile emazingeni okushisa esevisi aphakeme. Ama-alloys e-Magnesium afana ne-AZ91D, AM60B, kanye ne-WE43 anikezela ngezilinganiso ezingenakuqhathaniswa zamandla nesisindo-kodwa kuphela uma inqubo yokukhipha ukufa ilawula i-hydrogen porosity, inciphisa i-die soldering, futhi ikhiya ukubekezelelana okungu-±0.05 mm ezicini ezincane njengo-0.8 mm ukujiya kodonga. Lelo zinga lokulawula alenzeki kuma-generic foundries.
Senze izindlu ze-magnesium ze-WE43 ezingaphezu kuka-12,000 zama-actuator asebenza ngaphansi komhlaba—futhi iqoqo ngalinye liphumelele ukuhlolwa kwe-X-ray okungu-100% ngaphandle kokuncipha komhlaba. Kungani? Ngoba ukunemba kwe-magnesium die cast akukhona ngemishini emikhulu noma izikhathi zomjikelezo osheshayo. Imayelana nokuphatha izinga lokushisa elincibilikayo phakathi kuka-±3°C, ukugcina ukuphela kwendawo engaphansi kuka-Ra 0.4 μm, nokusebenzisa ukugcwaliswa okusizwa ngevacuum ukucindezela ukungena kwefilimu ye-oxide. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., i-magnesium asiyiphathi “njenge-aluminium ekhanyayo,” kodwa njengensimbi esebenzayo, elambile komoya-mpilo efuna ukuba kusetshenziswe amathuluzi akhethekile, ukuvikela igesi engasebenzi, kanye nokuqapha ukucindezela komgodi ngesikhathi sangempela.
Ukwehluleka okuningi kokuphonswa kwe-magnesium kubuyela emuva ezikhaleni ezintathu ezingagwemeka: ukuhluzwa okusanhlamvu okungahambisani ngesikhathi sokuqina, ukusatshalaliswa kwesigaba se-intermetallic okungalawuleki (ikakhulukazi i-Mg.17Al12), kanye nokuhlanekezelwa kwangemuva kokusakazwa okuvela ekuphumuleni kokucindezeleka okusele. Sivala lezo zikhala ngokuhlanganisa ukulingisa kokulingisa ngemephu ye-in-die thermocouple yangempela-bese siqinisekisa i-mold geometry ngayinye ngokumelene nemigoqo eqinile ye-ASTM B94-22 kanye nokuhlolwa kwesilinganiso sokuvuza kwe-ISO 11992-2. I-sand-cast magnesium prototypes yethu ifinyelela i-Cpk ≥ 1.67 kuma-callouts abalulekile e-GD&T; ukukhiqiza ugijima ku-±0.03 mm ku-coaxiality phakathi kwezibhobo ezithwalayo nama-flange akhuphukayo-ngaphandle komshini wesibili.
Ukuhlanganiswa okuqondile kwenza umehluko. Ngenkathi amafekthri amaningi abizwa ngokuthi "ukunemba" akhipha ukwelashwa kokushisa noma ukuqeda i-CNC, silawula uchungechunge olugcwele: ingxubevange ye-magnesium encibilika kuma-graphite crucibles ngaphansi kwe-SF.6/CO2 igesi yekhava, i-vacuum die casting die casting at 720–740°C melt temp, isixazululo se-T6 annealing ngamarempu alawulwayo, nokuqinisekiswa kokugcina kwe-CMM kusetshenziswa i-Zeiss CONTURA G2 enokuskena okuthintekayo. Lokhu kuqeda amaphutha esixhumi esibonakalayo—awekho ama-datum angaqondani kahle phakathi kwe-Foundry nesitolo somshini, awukho umlando wokushisa ofihliwe othinta ukusebenza kahle. Lapho i-OEM yephampu yase-Europe idinga izindlu ze-magnesium cylinder ezinobubanzi obungu-0.1 mm ebusweni obungu-220 mm namandla esivuno angu-300 MPa, saletha izingxenye ze-athikili yokuqala ngezinsuku eziyi-18—hhayi ngoba sashesha, kodwa ngenxa yokuthi imephu yethu yenqubo ayinakubambezeleka okungekho.
Ukusebenza komhlaba wangempela kubaluleke kakhulu kunamashidi acacisiwe. Ikhasimende elilodwa libike impilo ende yesevisi engu-40% kumarola we-magnesium winch centre shaft uma kuqhathaniswa nokulingana kwe-aluminium—ngemuva kwemijikelezo engu-12,000 ngaphansi komthwalo weradial ongu-85 kN kanye nokuchayeka kwesifutho sikasawoti. Kungani? Ukufakwa kwethu kwe-cobalt-nickel okuhambisana ne-AMS 5387 okuboshelwe ezindlini ze-magnesium kugcine ubulukhuni ngaphezu kuka-42 HRC kuyilapho ingxubevange idonsa amandla okudlidliza. Leyo dizayini eyingxube isebenza kuphela lapho amaqembu asakazayo nawomshini abelana ngemihlangano efanayo yokubuyekeza ubunjiniyela—futhi lapho ukulandeleka kokubalulekile kuxhumanisa ingxenye ngayinye nengxenye yayo yoqobo ye-ingot, ilogu yomlilo, kanye nombiko wokuhlola oqinile. Asimane nje sihlangabezane ne-ISO 9001:2015—sishumeka izibuyekezo zengozi yesitayela se-AS9100 kukho konke ukuqaliswa kwephrojekthi entsha ye-magnesium.
Uma udinga a ukunemba okuphezulu kwe-magnesium alloy die casting factory ephatha i-magnesium njengento yobunjiniyela besakhiwo—hhayi nje into engenasisindo—udinga isiyalo senqubo, ukuziphendulela nge-metallurgical, kanye nokungabekezeleli nhlobo ukuqagela. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iletha lokho kuqina kuwo wonke ama-hydraulic manifolds, izisekelo zephampu, kanye nezingxenye zemoto ezibaluleke kakhulu. Ukunemba kuqala lapho ukuncibilika kuhlangana khona-futhi kuhlala kukhiyelwe ngaphakathi kuze kuhlolwe okokugcina.
