Waxay leedahay afar hab oo wax-soo-saar ah, marka hore waa riixaya qaabaynta.(Budada magnetic iyo xabagta ayaa si siman isku qasan marka loo eego cabirka mugga ee ku saabsan 7:3, lagu rogrogay dhumucda loo baahan yahay ka dibna la adkeeyey si loo sameeyo badeeco dhammaatay), tan labaadna waa qaabaynta duritaanka.(Ku qas budada magnetka leh binder, kulaylka iyo cajiin, pre-granulate, qalalan, ka dibna u dir usha hagaha wareega ee qolka kulaylka ee kululaynta, ku duri godka caaryada ah ee wax-qabashada si aad u hesho badeecada dhammaatay qaboojinta ka dib). Midda saddexaad waa qaabaynta extrusion.(Waxay asal ahaan la mid tahay habka qaabaynta duritaanka, farqiga kaliya ayaa ah in kululaynta ka dib, pellets ayaa lagu sii daayaa caaryada iyada oo loo marayo dalool loogu talagalay qaabeynta joogtada ah), iyo tan afraad waa isku-darka isku-dhafka (isku qas budada magnetic iyo binder si waafaqsan saamiga, granulate oo ku dar qadar go'an oo ah wakiilka isku-xidhka, ku cadaadi caaryada, ku adkee 120 ° ~ 150 °, ugu dambeyntii hel alaabta la dhammeeyey.)
Khasaaraha ayaa ah in isku xidhka NdFeB uu bilaabo goor dambe, iyo sifooyinka magnetic waa daciif, ka sokow, heerka codsigu waa cidhiidhi, iyo qiyaasta sidoo kale waa yar tahay.
Faa'iidooyinka ay yihiin remanence sare, xoog jujuub sare, alaabta tamarta magnetic sare, waxqabadka-qiimaha saamiga sare, hal mar la sameeyo iyada oo aan processing sare, oo waxaa laga dhigi karaa magnets kala duwan oo qaabaysan, taas oo si weyn u yaraynaysaa mugga iyo miisaanka ee matoor.Oo waxay noqon kartaa magnetized jiho kasta, kaas oo fududayn kara wax soo saarka ee tiir multi-ama xataa aan xad lahayn guud ahaan magnets.
Waxaa inta badan loo adeegsadaa qalabka otomaatiga ah ee xafiiska, qalabka korantada, qalabka maqal-muuqaalka, qalabka, matoorada yar-yar iyo mishiinnada cabbiraadda, matoorada gariirada taleefanka gacanta, rollers magnetka printer, qalabka korantada ee diskiga adag ee matoorrada HDD, matoorada kale ee micro DC iyo aaladaha otomaatiga ah.

Tilmaamaha Alaabta
Astaamaha magnetka ee NdFeB ee xidhan:
1. Hantida magnetic inta u dhaxaysa magnet NdFeB sintered iyo ferrite magnet, waa waxqabadka sare isotropic magnet joogto ah oo joogto ah iyo xasilooni.
2. Waxaa laga samayn karaa birlab joogto ah oo cabbirro yar yar ah, qaabab adag iyo saxnaanta joomatari sare oo leh qaabaynta saxaafadda iyo qaabaynta duritaanka.Way fududahay in la gaaro wax soo saar otomaatig ah oo baaxad weyn.
3. Waxaa lagu dhejin karaa jiho kasta.Tiro badan ama xitaa tiirar aan la tirin karin ayaa lagu xaqiijin karaa NdFeB.
4. Matoorada NdFeB ee xidhan ayaa si weyn loogu isticmaalaa dhammaan noocyada matoorrada yaryar, sida matoorrada dunta, matoorka isku-dhafka ah, matoor-matoor, motor DC, mooto aan burush lahayn, iwm.
