Xa uqala ukukhangela ababoneleli bezinto ezichanekileyo, into yokuqala ekubethayo lulwandle lweewebhusayithi eziphantse zifane, zonke zithembisa umgangatho ophezulu, ukunyamezela okuqinileyo, kunye nexabiso elikhuphisanayo. Kulula ukulahleka kwijargon. Owona mceli mngeni kukungafumani mthengisi; kukufumana lowo owuqondayo umahluko phakathi komzobo ephepheni kunye nenxalenye esebenza kwindibano yokwenene. Abathengi abaninzi kakhulu, ngakumbi abo baqala ukufunwa, benza impazamo yokubeka phambili ixabiso leyunithi ngaphezu kwayo yonke enye into. Bagqiba ngeebhokisi zobuchwephesha be-spec castings ezingenamsebenzi ngenxa yokuba umphezulu ogqityiweyo awulunganga kwinkqubo yabo yokugquma, okanye ingqibelelo yangaphakathi ayikwazi ukuphatha ukulayisha okuguquguqukayo. Kulapho umsebenzi wokwenyani uqala khona.
Umdlalo weShell: Ngakumbi kuneMngundo nje
Makhe sithethe malunga nokubunjwa kweqokobhe, inkqubo eqhelekileyo emininzi ababoneleli bezinto ezichanekileyo umnikelo. Ephepheni, yinkqubo yentsimbi kunye namalungu entsimbi anomphezulu ongcono kunomphezulu wesanti. Kulula, akunjalo? Inyani imbi ngakumbi. Ndikhumbula iprojekthi yendlu yempompo, i-middle-volume eqhutywa kwi-iron ductile. Iisampulu zokuqala ezivela kumthengisi omtsha zikhangeleka zigqibelele. Kodwa ngexesha lovavanyo lwethu loxinzelelo, sine-30% yezinga lokungaphumeleli kwi-micro-porosity. Umthengisi waqhubeka egxininisa ukuba ikhemistry yayiza kucacisa. Umba yayingesosiqinisekiso semathiriyeli; yayingumjikelo wokumisa iigobolondo ze-ceramic kunye ne-curve yeqondo lokushisa lokuthulula-izinto ezingazange zivele kwisicatshulwa esiqhelekileyo. Umthengisi olandela iresiphi ngaphandle kokuqonda i-physics yokuqina kwiqokobhe lityala. Apha kulapho ubunzulu benkampani bubonisa. Ivenkile efana neQingdao Qiangsenyuan Technology (QSY), eneminyaka engama-30 exeliweyo, kusenokwenzeka ukuba inalo lwazi lwenkqubo yokubhaka. Udinga iqabane elinokuthi, Kule geometry kwi-iron ductile, kufuneka silungise i-gating apha ukuthintela oko kuncipha, kungekhona nje, Ewe, sinokukwenza.
Oku kukhokelela kwisigaba esibalulekileyo, esihlala singahoywa, saphambi kokuveliswa. Abona baboneleli bangcono baphatha izixhobo zokuqala kunye nophuhliso lwenkqubo njengophando oluhlangeneyo. Bafanele ukuba babuza intaphane yemibuzo: Yintoni umsebenzi walo mbutho? Yeyiphi imiphezulu yokunxiba ebalulekileyo? Ngaba yinxalenye yolwakhiwo okanye ubukhulu becala bubuhle? Ngaba izakwenziwa ngoomatshini kamva? Ndiye ndacela ababoneleli ukuba babone iindawo zokukhwelana okanye umzobo wendibano. Luphawu oluhle olo. Kuthetha ukuba bacinga malunga nokufaneleka kunye nokusebenza, kungekhona nje ukwenza ipateni ye-wax. Iwebhusayithi ye-QSY ikhankanya ukuba benza zombini ukuphosa kunye nomatshini we-CNC. Yinzuzo enkulu leyo. Umthengisi odibeneyo uyaziqonda izibonelelo zoomatshini kwasekuqaleni. Bayazi ukuba bangongeza phi isitokhwe esongezelelweyo kwipasile yokucoca kunye nendawo yokubamba idimension ye-as-cast ukukongela imali kumatshini. Iphelisa i-classical finger-pointing phakathi kwe-Foundry kunye nevenkile yomatshini xa inxalenye ingekho kwindawo.
Ukukhetha izinto eziphathekayo yenye indawo elungele ukucinga. Uninzi lwababoneleli luluhlu lwensimbi engenasici, intsimbi, i-alloys. Kodwa usathana ukumabanga kwaye inyibilika practice.
