Uyilo ngokubumba inaliti yentsimbi

Ukubumba inaliti yentsimbi (MIM) kuguqula uyilo lwangoku kunye nokubumba inaliti yentsimbi ngokudibanisa ukuguquguquka kokubumba inaliti yeplastiki kunye nokomelela kwentsimbi. Ivumela ukuyilwa kwejiyometri entsonkothileyo, njengemisonto kunye nemikrolo, ngochaneko olukhethekileyo. Imizi-mveliso efana nezonyango, iimoto, kunye ne-aerospace ixhomekeke ngakumbi kwi-MIM kumacandelo asebenza kakhulu ngenxa yokukwazi ukuvelisa iinxalenye ezikhaphukhaphu, ezomeleleyo ezinenkunkuma encinci. Imfuno yamacandelo amancinci kwi-elektroniki kunye nokhathalelo lwezempilo igxininisa ngakumbi ukubaluleka kwayo. Ngokunikezela ngokuguquguqukayo ekukhetheni izinto kunye nokuhambisa iziphumo ezikufutshane ne-net-shape, i-MIM ixhasa ukuveliswa kwezinto ezintsha nezizinzileyo.

Izinto eziphambili zokuThatha

• Isitofu sesinyithi sokubumba(MIM) ixuba isinyithi esomeleleyo kunye nokubunjwa kweplastiki. Idala uyilo oluneenkcukacha kwaye inciphisa inkunkuma.

• Ukukhetha uyilo lwesango elifanelekileyo kunye nobukhulu bodonga ngundoqo. Oku kumisa iimpazamo kwaye kugcine umgangatho ophezulu wemveliso.

Izibonelelo ze-DESIGN NGENXA yokubumba inaliti yentsimbi

Ukufezekisa ukuchaneka kunye nokuntsonkotha

Ukubunjwa kwenaliti yesinyithi kuyagqwesa ekuveliseni izinto ezintsonkothileyo, ezichaneke kakhulu iindlela zemveli ezisokolayo ukuzifumana. Ndiyibonile indlela le nkqubo evumela ngayo ukuyilwa kweejometri ezintsonkothileyo, ezinje ngeentambo zangaphakathi, iindonga ezibhityileyo, kunye nemizobo emihle, ngokuchaneka okumangalisayo. Ngokunciphisa inkcitho yezinto eziphathekayo, i-MIM ayinciphisi nje iindleko kuphela kodwa ikwaxhasa izenzo ezizinzileyo zokwenziwa kwemveliso. Imizi-mveliso efana nezonyango kunye ne-aerospace izuza kakhulu kolu buchule. Ngokomzekelo, ukufakelwa kwe-orthopedic kunye namacandelo e-injini ye-injini ye-injini kufunaukuchaneka kunye nokuqina, enikezelwa yiMIM ngokufanelekileyo.

Ukuguquguquka kwe-MIM kwenza ukusetyenziswa kweentlobo ezahlukeneyo zesinyithi kunye ne-alloys, evumela abaqulunqi ukuba balungelelanise iimpawu zoomatshini kwizicelo ezithile. Oku kulungelelaniswa kunciphisa imfuno yokulungiswa okubanzi kwasemva kokulungiswa, konga zombini ixesha kunye nezibonelelo. Nokuba licandelo le-smartphone okanye isixhobo sotyando, i-MIM iqinisekisa umgangatho ongaguqukiyo kuyo yonke imveliso yomthamo ophezulu.

Iindleko-zokusebenza kwiMveliso eNkulu

I-MIM igqame njengeisisombululo esingabizi kakhuluukwenza amacandelo amancinci naphakathi ngobuninzi. Ngelixa utyalo-mali lokuqala kwizixhobo kunye nokubumba kunokubonakala kuphezulu, ixabiso ngenxalenye nganye liyancipha kakhulu njengoko imveliso ikhula. Ndiyibonile indlela le nto eyenza ngayo iMIM ibe nomtsalane ngakumbi kumashishini afana neemoto kunye nezixhobo zombane zabathengi, apho imveliso yomthamo omkhulu ibalulekile.

Le nkqubo ikwanciphisa iindleko zabasebenzi kwaye icuthe namaxesha okukhokela. Ngokusebenzisa ukuya kuthi ga kwi-97% yemathiriyeli, iMIM iyayinciphisa inkunkuma, ithoba ngakumbi iindleko zemveliso. Oku kusebenza kakuhle kwenza ukuba kube lukhetho olukhethwayo kwiinkampani ezijolise ekulinganiseni umgangatho kunye nokufikeleleka.

Ukuguquguquka kuKhetho lweMathiriyeli

Enye yezona zinto zinomtsalane weMIM kukuguquguquka kwayo ekukhetheni izinto eziphathekayo. Ukusuka kwintsimbi kunye ne-nickel ukuya kwii-alloys ze-titanium kunye ne-alloys ye-memory memory, uluhlu lwezinto ezikhoyo ziqinisekisa ukuba amacandelo ahlangabezana neemfuno ezithile zokusebenza. Ngokomzekelo, ii-alloys ze-titanium zifanelekile kwi-aerospace kunye nezicelo zonyango ngenxa yomlinganiselo wamandla-to-weight, ngelixa i-nickel-based superalloys igqwesa kwiindawo eziphezulu zokushisa.

Ndiqaphele ukuba oku kuguquguquka kuvumela iMIM ukuba ibonelele kumashishini ahlukeneyo. Nokuba yichromium enganyangekiyo kwi-corrosion yeendawo zemoto okanye ialloys ezithambileyo zemagnethi kwiziguquli, inkqubo iqhelana neemfuno ezahlukeneyo. Nangona kunjalo, kuyafaneleka ukuba uqaphele ukuba ayizizo zonke iintsimbi ezifanelekileyo kwi-MIM, kwaye abaqulunqi kufuneka baqwalasele ngononophelo ukuhambelana kwezinto eziphathekayo ngexesha lesigaba sokucwangcisa.

Ukudalwa kokungunda kunye nokutofa kwezinto

Inkqubo yokudala umngundo kulapho uyilo luthatha uhlobo lomzimba. Ndilandela uthotho lwamanyathelo ukuqinisekisa ukuchaneka:

1. Ukulungiselela i-Feedstock: Iipowder zetsimbi ezintle zixutywe kunye ne-thermoplastic binder ukudala i-homogenous feedstock.
2. Isitofu: I-feedstock ifakwe kwi-mold, eyenza "inxalenye eluhlaza."
3. Ukubophelela: I-binder isuswa ngokusebenzisa iindlela ezisekelwe kwi-thermal okanye i-solvent, ishiya "inxalenye ebomvu."

Le nkqubo iqinisekisa ukuba inxalenye igcina imilo yayo ngelixa ilungiselela inqanaba elilandelayo. Ulawulo olululo ngexesha lokutofa kunye nokubophelela kunciphisa iziphene ezifana ne-warping okanye ukuqhekeka.

Amanyathelo eSintering kunye nePost-Processing

I-Sintering yintliziyo yenkqubo ye-MIM. Ndifudumeza indawo emdaka ukuya ngaphantsi kwendawo yokunyibilika yesinyithi, ivumela amasuntswana ukuba adibane. Eli nyathelo liphucula iimpawu zomatshini, njengamandla kunye nobunzima, ngelixa ufezekisa imilinganiselo ekufutshane neyokugqibela.

• Ukuthintela iziphene ngexesha le-sintering:
  • Ndilawula ubushushu ukunqanda amadyungudyungu okanye ukuqhekeka.
  • Ndiqinisekisa ukubola okupheleleyo kwezinto eziphilayo ngaphambi kokufudumeza.
  • Ndigcina i-atmosphere echanekileyo yokuthintela ukusabela kweekhemikhali okungafunekiyo.

Iindlela zokusetyenzwa kwasemva kokusebenza njengoomatshini kunye nonyango lobushushu ziphucula ngakumbi indawo. La manyathelo anceda ukufezekisa ukunyamezela okuthile, ukugqitywa komphezulu, okanye imigangatho yokusebenza. Umzekelo, ndihlala ndisebenzisa ukugqiba komhlaba ukunyusa inkangeleko yezinto ezisetyenziswa kubathengi be-elektroniki.

Ngokuziqonda kakuhle ezi zixhobo kunye neenkqubo, ndinokudala amacandelo akumgangatho ophezulu ahlangabezana neemfuno zamashishini axhomekeke kwi-DESIGNS WITHukubumba inaliti yentsimbi.

IiNgcebiso eziSebenzayo ZOKUDLA NGENXA yokubumba inaliti yentsimbi

Ukuqinisekisa Ukutyeba kweendonga ezifanayo

Ukugcina ubukhulu bodonga obufanayo kubalulekile ekubumbeni inaliti yentsimbi.
