Uma uzwa 'ukujikijelwa kwesihlabathi esinamekwe nge-resin', abantu abaningi ngokushesha bafanekisela lezo zibunzi ezicwebezelayo, ezingenalutho zamabhulokhi enjini noma imizimba yamavalvu. Leso isithombe sencwadi yokufunda. Kodwa esitolo, akuvamile ukuthi kuhlanzeke. Iqiniso liwukuxoxisana okuqhubekayo phakathi kokuqukethwe kwe-sand resin, ukwakheka kwesango, kanye nokwanda okushisayo kwesihlabathi ngokwaso. Iningi labafikayo, ngisho nabathengi abathile, bacabanga ukuthi inguqulo nje yesihlabathi esiluhlaza. Lowo mbono oyiphutha uholela ezikhathini zokufunda ezibuhlungu, futhi ezibizayo.
Ukungaqondi Okubalulekile: Akuyona Nje Ukugqoka
Igama elithi 'coated' cishe selidukisa. Isho isendlalelo sokwenziwa. Empeleni, i-phenolic noma i-furan resin ayilona nje igobolondo; yiyona yonke i-matrix yesakhiwo. Inqubo yokwelapha—noma ngabe i-hot-box, i- warm-box, noma i-cold-box—ibeka yonke into kusukela ekuzinzeni kobukhulu kuya ekuguqukeni kwegesi ngesikhathi sokuthela. Ngike ngabona izitolo zigxumela amaphesenti e-resin ukuze zonge izindleko, kuphela zigcine zinesikhunta esiwayo ngesikhathi sokuphatha noma, okubi nakakhulu, sibangele ukukhubazeka okukhulu kwe-veining endaweni yokuphonsa. I-sweet spot inembile, futhi ishintsha ngokusekelwe ku-alloy. Isibonelo, ngama-alloys ane-nickel ephezulu, kufanele uqaphe kakhulu mayelana nokuthathwa kwesibabule kumasistimu athile e-resin.
Lapha yilapho ulwazi lwesikhathi eside ku-full-service foundry lubalulekile. Inkampani efana I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kanye neminyaka yawo engamashumi amathathu ekubumbeni nasekukhiqizeni imishini, cishe iye yashisa inhlaka nesihlabathi esanele ukuze kwakhiwe izingxube ezifanele. Abavele bathenge isihlabathi esinamekwe ngaphambili eshalofini; kungenzeka balungise ukwakheka kwemisebenzi ethile. Uma ususebenze isikhathi eside kangako, uqongelela umtapo wezincwadi wembangela-nomphumela: le nhlaka enaleyo ngxenyana yesihlabathi yezindlu zephampu yensimbi engagqwali ikhiqiza lokhu kuqedwa kwendawo, kodwa kubakaki bensimbi enezindonga ezincanyana, udinga i-catalyst ehlukile kanye nesikhathi sokuhlubuka esisheshayo.
Idizayini yokungena nokukhipha umoya yesihlabathi se-resin ingesinye isilo ngokuphelele. Ngenxa yokuthi isikhunta siqinile futhi asikwazi ukungena emanzini uma siqhathaniswa nesihlabathi esiluhlaza, amagesi aphumayo anemizila embalwa. Awukwazi ukuthembela ku-porosity yesikhunta. Ngifunde lokhu kabuhlungu kusenesikhathi, ngiklama isistimu yokufaka uchungechunge lwama-flange ensimbi ye-carbon. I-geometry yayilula, ngakho ngasebenzisa uhlelo olujwayelekile lokugijima. Umphumela awubanga ama-blowholes amangalisayo, kodwa ukugoba okuphikelelayo, okunesilinganiso esihle endaweni engaphezulu yokusakazwa—i-gas micro-pinholing. Ukulungiswa kwakungewona ama-vents amaningi, kodwa ukucabanga kabusha okuphelele kokuthi insimbi yangena kanjani emgodini ukuze ikhuthaze ukugcwaliswa okuzolile. Yilokhu kwehluleka okucashile okuhlukanisa isitolo semisebenzi nochwepheshe.
Ukuhambisana Kwezinto Ezibalulekile: Lapho Ingxubevange Ilawula Inqubo
Uma sikhuluma ngama-alloys, lokhu kuhlangana okubalulekile. Ukukhishwa kwesihlabathi esifakwe nge-resin ayifani nosayizi owodwa kuyo yonke insimbi. Icwebezela izinsimbi, izinsimbi ezingenasici, futhi ikakhulukazi lezo zinhlu ezikhethekile zama-alloys akhohlisayo we-QSY, njenge-cobalt ne-nickel-based. Kungani? Ngoba isikhunta sinikeza ukunemba okuhle kakhulu kwe-dimensional kanye nesiphetho esihle sangaphezulu sama-alloys avame umshini kamuva. Kodwa uhlelo lwe-resin kufanele lukhethwe ukugwema ukusabela kwamakhemikhali. Ukuthela insimbi ene-manganese ephezulu esikhunjeni esinekhemistri engalungile yokuqhekeka kwe-resin kungaholela ekuthuthukisweni kwekhabhoni embi esikhumbeni sokuphonsa, ukuguqula imilimitha yokuqala yensimbi ibe uqweqwe oluqinile, olungenakuqhathaniswa.
Ngensimbi eyinsimbi, ikakhulukazi i-iron empunga, indaba ehlukile. Inqubo iyasebenza, kodwa icala lezomnotho kufanele libe lilungile. Ukunemba kwe-dimensional ephezulu kwesinye isikhathi kuyaqina ekubunjweni kwensimbi okulula lapho isihlabathi esiluhlaza singenza khona. Kodwa-ke, ezingxenyeni zensimbi eziyinkimbinkimbi, ezinezigaba ezincane ezidinga ukunemba, njengezingxenye ezithile zezimoto, kudingekile. Okubalulekile ukuthi ungaphoqi inqubo lapho ingekho khona. Ngikhumbula iphrojekthi yochungechunge lwezembozo zemigodi—ijometri elula ngokuphelele. Iklayenti ligcizelele ekubunjweni kwegobolondo 'lekhwalithi'. Sikwenzile, kodwa izindleko zeyunithi zazingenangqondo. Inzuzo 'yekhwalithi' ibingabonakali. Inqubo kufanele ihambisane nezidingo zokusebenza nezomnotho zengxenye.
Lobu buchwepheshe bezinto ongazilindela kusukela ekusebenzeni okuhlanganisiwe okuqondile. Uma sibheka ububanzi be-QSY-kusuka egobolondweni nasekufakweni kwe-investimenti kuya kumishini ye-CNC-ukusebenzisa kwabo isihlabathi esifakwe nge-resin cishe iyisixhumanisi samasu kulelo ketango. Abagcini nje ukwenza isikhunta; benza i-pre-form yezikhungo zabo zokwenza imishini. Ukulingisa kufanele kube nokuhluka okuncane, ukuncipha okungabikezelwa, kanye nendawo engaguquki ukuze kuqinisekiswe ukuthi izinqubo ezilandelayo ze-CNC zisebenza kahle futhi azilahli. Inqubo ye-Foundry yakhelwe kucatshangwa ngomshini wokuqeda. Lelo izinga lokuhlanganisa olithola kuphela emashumini eminyaka okuphatha konke ukuhamba komsebenzi.
UDeveli Ngemininingwane: Izinga lokushisa, Isikhathi, kanye Nodoti
Izinto ezimbili zokusebenza ezingalokothi zibonise ebhukwana: ukulawula izinga lokushisa nokubuyiselwa kwesihlabathi. Inqubo yokumboza iyazwela kumswakama osendaweni kanye nezinga lokushisa. Esitolo esingalawulwa yisimo sezulu e-Qingdao esogwini, isibonelo, umswakama wasehlobo ungadlala umonakalo ngezikhathi zokwelapha nokugeleza kwesihlabathi. Ugcina usulungisa amaphesenti e-catalyst usuku nosuku, cishe ngokuzizwa. Iwubuciko obusekelwa isayensi.
Bese kuba nesihlabathi esisetshenzisiwe—'isihlabathi esisekelayo' noma isihlabathi esishiswa ngokuthinta insimbi eshisayo. Awukwazi ukuvele ulilahle. Ukubuyisela okushisayo okusebenzayo kubalulekile kukho kokubili izindleko nokungaguquguquki. Isihlabathi esibuyiswe kabi sinenhlaka efile, i-char, nezinhlawulo ezicekela phansi ukusebenza kwesihlabathi esisha esimboziwe. Uma uxuba esihlabathini esibuyiswe kakhulu ngaphandle kokumiswa okufanele, amandla esikhunta sakho ayehla. Ngivakashele ama-Foundries anezinto ezintsha ezinhle zokuhlanganisa ezonakaliswe umugqa wokubuyisela kabusha we-subpar. Lonke uhlelo luqinile kuphela njengesixhumanisi salo esibuthakathaka. Inkampani evuthiwe iye yaba nesikhathi—futhi cishe inhloko-dolobha—yokutshala imali ohlelweni lwesihlabathi oluvaliwe olugcina ukungaguquguquki.
Enye imininingwane ye-gritty ukugqokwa kwephethini. Ngenxa yokuthi isihlabathi siyaluma futhi amaphethini asetshenziswa endaweni eshisayo, elaphayo, uhlelo lokugcinwa kwamathuluzi lunolaka. Okusalungiswa kwephethini egugile noma ipuleti lephethini elisontekile alithinti nje isikhunta; kungabangela ukuhluleka kokukhumula lapho igobolondo eliphulukisiwe likhala. Lokhu akulona ithiyori. Kuholela ekunciphiseni isikhathi, ama-patchwork okwenziwa ngesandla kuma-molds, kanye nokukhishwa kwe-casting. Isitolo sephethini siyingxenye ebalulekile, ngokuvamile engaphansi, yokusebenza ngempumelelo kwesikhunta segobolondo.
Lapho Ihluleka: Ukufunda Ukulingisa Njengendaba
Ukuhlaziywa kokwehluleka kulapho kuhlala khona ulwazi lwangempela. Isici sokulingisa inqubo yokubhala umbiko. Ngesanti ye-resin, amaphutha anesignesha ethile. I-Veining, ngokwesibonelo, lezo zibikezelo ezifana ne-fin endaweni yokuphonsa, ngokuvamile zilandela emuva ekwandeni kokushisa kwesihlabathi kanye nokuqina kwesikhunta. Ikutshela ukuthi imiksi yakho yesihlabathi kungenzeka icishiwe, noma ukushisa kwangaphambili kwephethini akuhambisani. Ukushiswa, ungqimba oluqinile, oluhlanganisiwe lwesihlabathi ensimbi, lukhomba ukushisa okukhulu futhi okungenzeka kube inhlaka ephuka ngamandla kakhulu.
Isici esicashile kakhulu singase sibe i-porosity ehlobene negesi. Njengoba kushiwo, ngenxa yokuthi isikhunta asinazo izimbotshana, igesi kufanele iphume ngezintuba eziklanyelwe noma iphoqwe ukuba ibe yisixazululo ensimbi. Uma ukungena kwakho komoya kunganele noma izinga lokushisa lokuthela liphezulu kakhulu, uthola i-porosity. Kodwa nali iqhinga: ukuhlukanisa phakathi kwegesi esikhunjeni kanye negesi ensimbi ngokwayo (njenge-nitrogen pinholing). Indawo, ukuma, kanye nendawo yangaphakathi yembotshana kuyizinkomba. I-mold gas porosity ivame ukuvela ngaphansi nje kwendawo yokuphonsa, iyindilinga, futhi inengaphakathi elicwebezelayo, eline-oxidized. Ukuyixazulula kungase kusho ukulungisa uhlobo lwe-resin, ukunciphisa i-catalyst, noma ukwengeza ama-vents amaningi-hhayi ukulungisa i-chemistry encibilikayo. Leli khono lokuxilonga limsulwa, liqoqiwe, lisebenza ngezandla.
I-synthesis: Kungani Ubungcweti Nomlando Kubalulekile
Ngakho-ke, ukuzungeza emuva, kusho ukuthini konke lokhu kumuntu ofuna umthombo othembekile ukukhishwa kwesihlabathi esifakwe nge-resin? Kusho ukubheka ngale kohlu lwemishini. Kusho ukufuna irekhodi eliphakamisa ukujula kokuxazulula izinkinga. Ukuphila isikhathi eside kwenkampani, njengomlando we-QSY weminyaka engama-30, kuwummeleli walokhu. Kusho ukuthi baye basinda kumajika okufunda, ukushoda kwezinto ezibonakalayo, izilingo ezihlulekile, futhi balungise inqubo yabo yafinyelela ezingeni lokwethembeka. Kungenzeka ukuthi babone ukuvela kobuchwepheshe be-resin kusukela ekuqaleni, izinhlelo ezisindayo zomusi ukuya kuzibophezelo zanamuhla eziqaphela kakhulu imvelo.
Ukunikeza kwabo izinqubo ezihambisanayo—ukutshala imali kobumo obuyinkimbinkimbi kakhulu, umshini we-CNC wezingxenye eziqediwe— nakho kuyakhuluma kakhulu. Kubonisa ukuthi bayaqonda ukuthi ukubumba amagobolondo kufanelana kuphi ne-ecosystem yokukhiqiza ebanzi. Akulona ithuluzi kuphela, kodwa elikhethekile lezinhlelo zokusebenza ezithile: amajiyometri ayinkimbinkimbi kuma-alloys afunayo lapho ukunemba okuvela ku-cast state kunciphisa izindleko zomshini kanye nengozi.
Ekugcineni, ukukhishwa kwesihlabathi esinamekwe nge-resin okuphumelelayo akuphathelene nefomula. Imayelana nokulawula okujwayelwe, okucishe kube okunembile, kweziguquguqukayo eziyikhulu ezisebenzisanayo. Kumayelana nokwazi ukuthi isimo sezulu kusasa singashintsha ingxube yesihlabathi sakho namuhla, nokuthi impumelelo yengxenye engu-$50,000 eyenziwe ngomshini iqala ngokukhethwa kwesikhwama esingu-$5 senhlaka. Lolo uhlobo lobuchwepheshe obusekelwe phansi, obungenabuhle obuvela ngokuwenza usuku nosuku, usuku nosuku, amashumi eminyaka. Futhi yilokho okuthengayo ngempela.
