Ukulingisa kwesihlabathi kuqhathaniswa kanjani nokuphrinta kwe-3D kwezingxenye ze-aluminium?
Ukuphrinta kwe-3D (I-Additive Manufacturing) kuhle kakhulu kuma-prototypes ayinkimbinkimbi kakhulu, anevolumu ephansi ngaphandle kokusetshenziswa kwamathuluzi. Kodwa-ke, kumavolumu angaphezu kwamayunithi angama-50-100, ukubunjwa kwesihlabathi kubiza kakhulu. Ukulingisa kwesihlabathi nakho kunikeza izakhiwo eziphakeme zokumakhenikha kanye nokuminyana kwezinto ezibonakalayo uma kuqhathaniswa nezinye izinqubo zokuphrinta zensimbi ze-3D. Izindlela ezihlanganisiwe, njengesikhunta sesihlabathi esiphrintiwe se-3D, ziyavela ukuze zihlanganise izinzuzo zazo zombili lezi zobuchwepheshe.
Yikuphi ukuphela kwendawo okungalindelwa?
Ukuqedwa kwe-As-cast surface kuvame ukusuka ku-Ra 6.3 kuya ku-12.5 micrometers. Lokhu kulukhuni kunokulingisa ifa kodwa kwanele ezinhlelweni eziningi zezimboni. Uma kudingeka ukuqedwa okushelelayo, ukuqhunyiswa kwesibhamu, ukuwa, noma ukukhanda imishini kungasetshenziswa. I-Powder coating noma i-anodizing nayo ingasetshenziselwa izinjongo zobuhle kanye nokuvikela ukugqwala.
Isiphetho: Ukubambisana Kokunemba Nokusebenza
Izingxenye ze-sand cast aluminium zimelela insika yokukhiqiza kwezimboni zesimanje, enikeza inhlanganisela engenakuqhathaniswa yenkululeko yokuklama, ukusebenza kwezinto ezibonakalayo, nokusebenza kahle kwezomnotho. Noma ngabe uthuthukisa ingxenye yezimoto entsha, uthuthukisa imishini yezimboni, noma uthola izingxenye zengqalasizinda yamandla, ukuqonda izici ezihlukahlukene zokwenziwa kwesihlabathi kukunika amandla okwenza izinqumo ezinolwazi.
Ngokusebenzisa ubuchwepheshe bomkhiqizi ozinikele, ungazulazula ezintweni eziyinkimbinkimbi zokukhetha ingxubevange, ukwenziwa ngcono kwedizayini, nokuqinisekiswa kwekhwalithi. Umphumela uba ingxenye engafinyeleli nje kuphela imininingwane yobuchwepheshe kodwa futhi ethuthukisa inani lomkhiqizo wakho wokugcina. Kusukela ku-prototype kuya ekukhiqizweni, ubambiswano olulungile luqinisekisa ukwethembeka, ukukala, kanye nenzuzo yokuncintisana.
Ngo Inkampani Botou Haijun Metal Products Co., Ltd., siyaqonda ukuthi ukunemba akumi esigabeni sokulingisa. Nakuba sisebenza ngokukhethekile ocwaningweni, ekuthuthukisweni nasekukhiqizweni kwezinto eziguquguqukayo nezinembayo eziphezulu namathuluzi okusebenza kwensimbi, ukuzibophezela kwethu ekuhlinzekeni ngezixazululo ezisebenzayo zokushisela nokubeka endaweni kuhambisana nesimiso sokukhiqiza. Ulayini wethu womkhiqizo oyinhloko, ohlanganisa izinkundla zokushisela eziguquguqukayo ze-2D ne-3D, kanye nezinsiza ezifana namabhokisi ayisikwele anomumo ongu-U/L nama-engeli avamile, anikezela ngemikhakha efanayo—yomashini, eyezimoto, ne-aerospace—ethembele ezingxenyeni ze-aluminiyamu zesihlabathi ezisansimbi zekhwalithi ephezulu. Njengoba nje izinkundla zethu zokushisela ze-cast iron 3D ziqinisekisa ukuqina nokuqina okukhethekile ekuhlanganisweni, indlela yethu yokusebenzelana kwezokukhiqiza igcizelela ukunemba nokwethembeka. Sizinikezele ekusekeleni imboni yesimanje yokukhiqiza ngokuqinisekisa ukuthi yonke ingxenye, kusukela kwabalingisi bokuqala kuya emkhiqizweni wokugcina ohlanganisiwe, ihlangabezana namazinga aphezulu kakhulu ekhwalithi.
Uma ufuna umphakeli omethembayo ozokwenza imiklamo yakho iphile, cabanga ngezinsizakalo zethu zokukhiqiza ezibanzi.
