1. Raw materials
Casting-Kukanda zvinhu zvinowanzova zvisiri-ferrous zvinhu, sengealuminium, magnesium, zinc, iyo ine nzvimbo dzakaderera dzekunyungudika. Chimiro chechigadzirwa chekukanda chinogona kuva ndiro, bhanhire, tsvimbo, nezvimwewo;
Upfu metallurgy– Metal kana simbi hupfu (kana musanganiswa wesimbi hupfu uye upfu husina simbi) semidziyo. Kunyange zvazvo pane murezaupfu simbi zvinhu, zvinokwanisikawo kusanganisa hupfu. Izvi zvinobvumira kugadzirwa kwezvinhu zvakanangana, senge yakakwira magineti emidziyo yemota, inoda yakakwira melting point metal powders. Powder metallurgy kazhinji ine zvinhu zvinotevera:Stainless simbi, simbi, nickel, titanium, mhangura, nesilicon, phosphorus.

2. Maitiro
Casting- iko kushandiswa kwezvinhu kubva kumvura kuenda kune yakasimba chikamu chekuchinja kuumbwa, simbi inonyungudika zvachose, yekupedzisira chigadzirwa chimiro chinoshanduka.
Upfu Metallurgy- ndiyo tekinoroji yekugadzira simbi kana simbi hupfu (kana musanganiswa weupfu hwesimbi uye isiri-simbi hupfu) seyakagadzirwa, kugadzira uye sintering, kugadzira zvinhu zvesimbi, macomposites nemhando dzakasiyana dzezvigadzirwa.
3. Kurapa kwekupisa
Casting- Zvinoenderana nezvinhu zvakasiyana uye zvinodiwa zvekuita zvinogona kuve neakasiyana kupisa kupisa maitiro, senge aruminiyamu alloy annealing, quenching, mhinduro kurapwa, kuchembera kusimbisa;
Upfu metallurgy- kwakajairika upfu simbi nzira, zvinhu hazvigoni kuva dense zvachose, zvisingadzivisiki kubudisa mamwe makwapa, achaderedza simba rayo, maererano siyana zvinodiwa zvinhu zvinhu, kuona kana kupisa kurapwa pashure sintering, kazhinji kuburikidza quenching uye tempering anogona kuvandudza kushanda zvinhu.
4. Kudzora kwesangano
Casting– Inkufa kukandira, kutonga kweiyo microstructure kunotarirwa nehuwandu hwekutonhora, hunoenderana nezvinhu zvakadai sepamusoro uye huwandu, uye sangano rekukanda rinowanzowedzera kukora.
Upfu metallurgy-Upfu nekuti iyo mbishi idiki, kuburikidza nekugadzirisa maitiro, inogona kuwana yunifomu zviyo, yakanaka microstructure, kudzivirira zvachose kuumbwa uye kuparadzaniswa kwemicrostructure kunogadzirwa nekukanda. Kutenderera kwega kwega kunoisa huremu hwakafanana hwehupfu muforoma uye hunoibatanidza kusvika pakuwanda kwakafanana. Powder metallurgy zvinhu zvinopisa isostatic kudzvanya, uye kuwanda kwezvinhu zvakajairwa sintered hazvina kunaka sekukanda.
5. Mechanical properties
Kuenzaniswa nemamwe maitiro,kufa kukandirainopa zvakanaka kwazvo kuumba kugona. Nekudaro, isu tinogona kushandisa ingangoita yakafanana dhizaini mikana seupfu simbi zvigadzirwa kupa zvigadzirwa zviri nani zvemichina.
Die cast materials haisi magineti. Kunze kwekunge dzakaiswa mukati mechimwe chikamu chakagadzirwa neimwe simbi, hapana magineti yakakodzera. Powder metallurgy ine zvakasiyana-siyana zvemagineti zviripo. Rimwe dambudziko rekukanda kufa nderekuti chigadzirwa hachina kusimba uye nyore kuputsika. Zvinhu zvikuru zvezvikamu zvekufa-cast zinc uye aluminium, izvo zviri zvinyoro zvesimbi zvinhu.Upfu metallurgy zvikamu, inowanzogadzirwa nesimbi, ine kuoma kwepamusoro. Kushandisa zvinhu zvakasimba zvinogona kuwana chimiro chakafanana nezvinhu zvishoma, izvo zvinogona kuchengetedza mota dhizaini nzvimbo uye uremu.
6. Mutengo
Component dhizaini ndiyo mutyairi mukuru wemutengo, kunyangwe dhizaini inogona kugadzirwa kuti ienderane nemaitiro ekuumba. Nekudaro, pane misiyano pakati pehupfu metallurgy zvigadzirwa uye kufa kukanda, uye misiyano iyi zvakare ndizvo zvinhu zvikuru zvinokanganisa mutengo.
Kushandiswa kwezvinhu/goho. Zvigadzirwa zvehupfu zvesimbi zvine mwero wezvikara zvakaderera, inova mukana mukuru mukushandiswa kwemhando yepamusoro-soro semhangura nesimbi isina tsvina.
Secondary processing. Die cast parts inoda kuchekwa kuti ibvise mipendero yakasvibira, inogadzirwazve uye inorapwa kupisa; Zvizhinji zvehupfu simbi zvikamu hazvidi zvechipiri kugadzirisa.
Raw material kushandiswa. Kunyunguduka kwesimbi kune simba rakawanda, kunyanya kune zvinhu zvine nzvimbo dzakanyanya kunyungudika. Kunyangwe sintering zvakare ine simba rakawanda, iyo yakazara yekushandisa sintering inogona kunge iri shoma pane yekukanda.
Powder metallurgy uye die casting maitiro maviri ane mukurumbira ekugadzira, imwe neimwe iine akasiyana mbishi zvinhu, maitiro, nzira dzekurapa kupisa, uye michina zvinhu. Nepo kufa kwekufa kuchiwanzo shandiswa nesimbi yakaderera-inonyungudika sealuminium uye zingi, poda simbi inoshandisa hupfu hwesimbi, ichipa mamwe magadzirirwo muzvinhu zvenyama, sekugadzira magineti zvinhu. Powder metallurgy inopa yepamusoro microstructure control, zvirinani kushandiswa kwezvinhu, uye kazhinji inobvisa kudiwa kwechipiri kugadzirisa, zvichitungamira mukudhura kwemari. Nekudaro, kufa kukandira kunobvumira kugona kuumba kwakanakisa, kunyangwe zvichigona kukonzera zvigadzirwa zvisina kusimba zvine simbi dzakapfava.
Kune mapurojekiti anoda kurongeka, simba repamusoro, uye kuderedzwa marara emidziyo, poda metallurgy inogona kupa yakakosha mukana. PaJHMIM, isu tine hunyanzvi hwepamberi poda metallurgy maitiro kuendesa emhando yepamusoro, akagadziridzwa simbi zvikamu zvemaindasitiri akasiyana. Funga kubatana neweskuti uwedzere kushanda kwechigadzirwa chako uye kunyatsogona kugadzira.
