Xa abantu abaninzi besiva inkampani elahlekileyo yokuphosa, bafanekisela isiseko esimnyama, esinothuli esenza iitrinkethi. Leyo yimbono yokuqala ephosakeleyo. Ubunyani bubuchwephesha obuphezulu, obuhlala bukhungathekisa, kunye nenkqubo evuzayo ngokunzulu yokuguqula iphethini ye-wax ebuthathaka ibe yinto eyomeleleyo, ephezulu yentsimbi. Asikokwenza nje izinto; imalunga nokusombulula iingxaki zejometri, imathiriyeli, kunye neendleko ezingenakuchukunyiswa zezinye iinkqubo.
I-Core ayiyo-wax, liqokobhe
Wonke umntu ulungisa kwi-wax. Ngokuqinisekileyo, iphethini ibalulekile, kodwa umlingo wangempela-kwaye apho iivenkile ezininzi zibonisa i-mettle yazo-kwisakhiwo se-ceramic shell. Apha kulapho inkampani ithanda khona Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) iyazahlula. Ayingomsebenzi wokudipha-ne-dunk. Ngumjikelo olawulwayo, weentsuku ezininzi zokuthi nkxu iqela le-wax kwi-slurry, ukuyifaka ngesanti ephikisayo, kunye nokomisa. Phinda. Isixhenxe, isibhozo, ngamanye amaxesha amaxesha alithoba. Ubukhulu, indawo yokomisa (umswakama lutshaba), i-granularity ye-stucco-umaleko ngamnye sisigqibo esichaphazela ukugqitywa komphezulu wokugqibela kunye nokuzinza kwe-dimensional. Yifumane kakubi, kwaye ufumana igobolondo eqhekezayo ngexesha lokukhupha (ngokuqhelekileyo kwi-autoclave) okanye, ngakumbi, ngexesha lokuthulula.
Ndikhumbula umsebenzi we-pump impeller, idizayini entsonkothileyo, eyivani ebhityileyo ngo-316. Iwax yayigqibelele. Amaqokobhe ambalwa okuqala yayiziincwadi zokufunda. Emva koko sabetha isipelingi esifumileyo. Iqela latyhala ukugcina ishedyuli, lidipha ngaphambi kokuba umaleko odlulileyo wome ngokupheleleyo. Isiphumo? Iqokobhe elihle elathi lakudubula lavelisa iintanda zeenwele. Intsimbi etyhidiweyo yangena, idala iifins kwi-vanes engenakwenzeka ukuyisusa ngaphandle kokuphazamisa iphrofayili. Ilahleko iyonke. Oko kusilela kwaba sisifundo esibuhlungu ekuhlonipheni inkqubo kwikhalenda. Sisifundo esimiliselwe kwimisebenzi ethathe amashumi eminyaka, njengerekhodi le-QSY leminyaka engama-30. Awukwazi ukukhawuleza iiceramics.
Eli qokobhe, xa sele ligxothiwe, liba yimonolithic, i-freestanding mold. Nantso inzuzo engundoqo. Akukho migca yokwahlula, akukho zi-engile zedrafti. Ivumela ezo geometries eziphambeneyo-iipaseji zangaphakathi, ii-undercuts, iimilo ze-organic-ezinokwenziwa kuphela ngeendleko ezigqithisileyo kunye nobunzima. Iqokobhe yindawo ethabathayo echaza ukubanakho kwendawo.
Isixhobo apho umdlalo utshintsha khona
Ukuphosa iwax elahlekileyo ayiseyomifanekiso eqingqiweyo yobhedu kuphela. I-spectrum yezinto zikhulu, kwaye ukhetho luchaza yonke into ukusuka kwiqondo lokushisa lokugalela ukuya kunyango lobushushu obusemva kokuphosa. Le yenye indawo apho amava angenakuxoxisana. Ukusebenza ngentsimbi yekhabhoni yinto enye; ukugalela ialloys esekwe nickel okanye ialloys esekwe cobalt sisilo esahlukileyo ngokupheleleyo.
Ezi superalloys zineendawo eziphezulu zokunyibilika kwaye zihlala zisebenza. Bafuna ukwakheka kweqokobhe elithile ukuthintela ukusebenzisana kwemichiza kobo bushushu bugqithisileyo. Inkqubo yokungena-imijelo ezondla isinyithi kwi-mold cavity-kufuneka yenziwe ngokuhlukileyo. Udinga iziseko zesprue ezikhulu kunye namasango acwangcisiweyo ngakumbi ukuze uqinisekise ukutya okufanelekileyo kunye nokunciphisa ukushwabana kwe-porosity kwezi mathiriyeli zibiza kakhulu. Uyilo oluqhelekileyo lwesango luya kulahla ibhetshi ye-Inconel ye-$10,000 ngemizuzu.
Ukujonga uluhlu lwezinto eziphathekayo zomthengisi kukuxelela okuninzi. Xa ubona uluhlu lwenkampani hayi nje intsimbi engenasici kwaye intsimbi, kodwa ukubiza ngokukodwa ii-alloys ezikhethekileyo, kubonisa isiseko esixhotyiswe umsebenzi ophuculweyo. Oku kuthetha ukuba banolwazi lwe-metallurgical kunye netekhnoloji yesithando somlilo ukuyiphatha. Yibheji ethe cwaka yesakhono. Intshayelelo emfutshane yendawo yeQSY (tsngtaocnc.com) ifumana oku kulungile-ikhokelela kunye neenkqubo kodwa ngokukhawuleza ibambelele kwizinto eziphathekayo, kubandakanywa nezo zixhobo ezikhethekileyo. Eso sisishwankathelo sengcali.
Umtshato ongenakuphepheka: Ukuphosa kunye ne-CNC
Nantsi inyani enzima: akukho kutyalomali oluphuma ngokugqibeleleyo. Kusoloko kukho ukucoca. Ukudanyaza kuqhagamshelo lwesango, amaqhuqhuva amancinane omphezulu ukusuka kuthungo lweqokobhe. Kwisibiyeli esilula, ivili lokusila linokwanela. Kodwa kumzimba wevalve echanekileyo okanye icandelo le-injini yomoya, udinga umatshini. Kungenxa yoko le nto abona banako iinkampani ezilahlekileyo zokulahla i-wax ayizizo ziseko nje; ziiyunithi ezidibeneyo zokuvelisa.
Ukuba ne-CNC machining endlini akukho lula; yimfuneko yolawulo. Oomatshini kunye neenjineli zesiseko kufuneka bathethe. Umfo owenza inkqubo ye-CNC kufuneka aqonde ukucutheka okunokwenzeka kokuphosa kunye namanqaku anokuthi agqwetheke ukuseka iimpawu ezichanekileyo zedatha. Ndibone iinxalenye zilahlwa kumatshini ngenxa yokuba ukuphosa kwakugqibelele kwipatheni ye-wax, kodwa ipateni ngokwayo ayizange iyilwe kunye nesitokhwe sokugqibela somatshini engqondweni. Yayisileleko soyilo esazalwa kwinkqubo ye-siled.
Oku kudityaniswa koko kuthetha ukuthini ukuchaneka kotyalo-mali. Yilophu ukusuka kuyilo lokungunda ukuya ekujuleni ukuya kumatshini wokugqibela ukuya ekuhlolweni. Inkampani enikezela zombini iqokobhe ngundo ukuphosa (inkqubo yomzala, rhoqo kwiindawo ezinkulu) kunye nomatshini ogcweleyo we-CNC phantsi kophahla olunye, njengoko kubonisiwe kumda wokusebenza we-QSY, iqulunqa ukusombulula yonke ingxaki, hayi nje isiqwenga sayo. Banokuthatha uxanduva lokuzisa inxalenye egqityiweyo, esebenzayo, kungekhona nje ukuphosa okugwenxa.
UMtyholi kwiiNkcukacha: Ukungena kunye nokuVelisa
Inzuzo kumsebenzi olahlekileyo wokugalela i-wax iphila kwaye ifa kwisivuno. Kwaye isivuno sinqunywe ngokukodwa kwigumbi le-wax, ngexesha lokuhlanganisana komthi. Kulapho ubugcisa budibana khona nezoqoqosho. Ngokwenyani udibanisa iipateni zewax kwisprue esiphakathi. Mangaphi amalungu onokuwafaka? Uziqhelanisa njani nokuqinisekisa ukuhamba kakuhle kwesinyithi kunye nokutya? Isentimitha nganye yaloo mthi sisinyithi esiya kunyibilika, sigalelwe, size kamva sisikwe size sinyibilike.
Uyilo lomthi olungasebenziyo lubulala umda wakho. Ngaphezulu kwesango inxalenye, kwaye uchitha isinyithi kwaye unyuse iindleko zomatshini. Ngaphantsi kwesango kuyo, kwaye ufumana i-shrinkage cavities, ukukrazula inxalenye ngokupheleleyo. Yiphazili yokwandisa rhoqo. Iinjineli zenkqubo ezigqwesileyo zinethala leencwadi lemifanekiso yengqondo-le milo ifuna isango eliphezulu, eli lifuna ukugcwala okusezantsi, eli candelo lingqindilili lifuna ukugodola ukulawula ukuqina. Kukho isoftware yale nto ngoku, kodwa intuition ekuboneni amawaka okugalela ayinakuphinda ithathelwe indawo.
Lo ngumqhubi weendleko ezifihliweyo abathengi abaninzi abawuxabisiyo. Babona ixabiso lenxalenye nganye kodwa hayi iiyure zobunjineli ezichithwe kukulinganisa kunye novavanyo lomzimba ukufumana ilungelo lokungena kwilungu elitsha. Isiseko esihle siya kuba ngaphambili malunga nesi sigaba sophuhliso. Asiyontlawulo eyongezelelweyo; ngumsebenzi osisiseko oqinisekisa imveliso ezinzileyo, enemveliso ephezulu eqhutywa kamva.
Ke, ujonge ntoni ngokwenene?
Xa uvavanya a inkampani yokulahla i-wax elahlekileyo, awuthengeli mpahla. Ukhangela iqabane lobugcisa. Iwebhusayithi, iphepha lokuthengisa-ziyimikhondo nje. Kufuneka umbe kulawulo lwenkqubo. Buza malunga nolawulo lwemozulu lwegumbi loonokrwece. Buza ukuba benza njani amasango e-alloy entsha. Cela ukubona imizekelo yendlela abaphatha ngayo iidatum zemachining kumphezulu wokuphoswa.
Olona vavanyo lukwindlela abathetha ngayo ngokungaphumeleli. Ngaba banamabali angezinto ezingahambi kakuhle noko bakufundileyo? Nayiphi na ivenkile ebanga i-100% yezinga lempumelelo iyaxoka okanye ayityhalanga imvulophu. Abaxabisekileyo, abo baneminyaka engama-30 yembali njengeqela elisemva kweQingdao Qiangsenyuan, baneziva kunye neendlela ezilandelelweyo zokungqina ukuba bebekwimisele. Ubomi babo obude ngokwawo yindawo yedatha.
Ekugqibeleni, kuhla ukuthembela kwinkqubo yoqeqesho lwabo. Ngaba banokutolika ngokuqhubekayo injongo yoyilo-nokuba ilula intsimbi isibiyeli okanye entsonkothileyo utyalo mali kwimonel—ibe yintsimbi ethembekileyo nenesandi? Nguwo kuphela umbuzo obalulekileyo. Okunye yiwax kunye ne-ceramic.
