Ƙarshe:Saboda tsananin taurinsa, gamawa bayan an gama yin gyare-gyare yawanci yana buƙatar amfani da kayan aikin lu'u-lu'u ko ƙafafun niƙa.
Wannan labarin yana mai da hankali kan matakai na yau da kullun na yau da kullun:
1. Busassun Matsawa
Wannan ita ce hanyar da aka fi amfani da ita wajen samar da masana'antu, musamman dacewa da yawan samar da siffofi masu sauƙi (kamar zanen gado, zobe, da washers).
Ka'ida:Ana sanya foda mai ɗaure a cikin wani ƙarfe na ƙarfe kuma an sanya shi zuwa matsi na unidirectional ko bidirectional ta amfani da latsa.
Amfani: Aiki mai sauƙi, babban inganci, madaidaicin girman jikin kore, da raguwar sintering cikin sauƙin sarrafawa.
Iyakoki:Wuya don kera sassa masu siffa mai rikitarwa; saboda karfin juzu'i, yawan manyan sassa na iya zama rashin daidaituwa.
2. Isostatic latsawa
Don manyan ɓangarorin aiki waɗanda ke buƙatar girma mai yawa da daidaituwa, latsa isostatic ita ce hanyar da aka fi so.
Ka'ida: Ana rufe foda a cikin wani nau'i na roba (yawanci jakar roba) kuma an sanya shi a cikin babban jirgin ruwa, ta yin amfani da ruwa a matsayin matsakaici mai watsawa.
Babban Amfani: Ana amfani da matsa lamba daidai gwargwado ga foda daga kowane kwatance, wanda ke haifar da daidaituwa sosai a ko'ina cikin koren jiki da ƙarancin nakasu bayan sintiri.
Aikace-aikace:Yawanci ana amfani da shi wajen kera manyan bututun yumbu, filaye, ko madaidaicin yumbun bearings.
3. Tape Simintin
Idan ka ga ƙananan yumbura mai ƙwanƙwasa (kamar allon kewayawa a cikin wayoyin hannu), ana iya yin su ta hanyar simintin faifai.
Ka'ida:Ana hada foda da sauran ƙarfi, tarwatsawa, da ɗaure don samar da “slurry,” wanda sai a baje shi akan bel mai ɗaukar nauyi ta hanyar amfani da ruwan likita don samar da fim mai ɗanɗano. Daga nan sai a busar da fim din a kware.
Amfani: Mai ikon kera zanen yumbu na bakin ciki mai tsananin kauri tare da kauri tsakanin 10 μm da 1 mm.
Aikace-aikace:Kauri-fim kewaye substrates, Multilayer yumbu capacitors (MLCC).
4. Gyaran allura
Ana amfani da wannan dabarar, aro daga masana'antar robobi, don kera sassan da ke da sarƙaƙƙiya na geometric.
Ka'ida:Ana haxa foda na alumina tare da babban adadin abin ɗaure na halitta (har zuwa sama da 40%), ana mai zafi, kuma a yi masa allura cikin daidaitaccen tsari, sannan a sanyaya kuma a ƙarfafa.
Kalubale:Tsarin "debinding" (cire kwayoyin halitta) kafin yin jima'i yana da tsayi sosai kuma mai mahimmanci; rashin kulawa na iya haifar da tsagewa cikin sauƙi.
Aikace-aikace:Sassan madaidaicin yumbu, kayan aikin likitanci.
5. Ƙirƙirar Ƙarfafawa (Buga 3D)
Wannan fasaha ce mai yanke hukunci a cikin 'yan shekarun nan da ke karya iyakokin da aka ƙera a kan siffa.
Manyan hanyoyin sun haɗa da: Stereolithography (SLA) ko manna extrusion.
Amfani: Ba a buƙatar ƙirar ƙira, yana mai da shi dacewa don haɓaka samfura ko kera yumbu tare da rikitattun sifofin ciki (kamar kwarangwal na biomimetic da guntuwar microfluidic).
