Ubuchwepheshe benqubo ye-powder metallurgy yokulungisa impushana yensimbi noma ukusebenzisa impushana yensimbi (noma ingxube yempushana yensimbi ne-non-metal powder) njengempahla eluhlaza, ngemva kokwakhiwa nokucwiliswa, ukwenza izinto zensimbi, izinto eziyinhlanganisela nezinhlobo ezihlukahlukene zemikhiqizo. I-powder metallurgy ifana nokukhiqizwa kwezitsha zobumba, zombili zingezobuchwepheshe be-powder sintering. Ngakho-ke, uchungechunge olushaamasu powder metallurgyingasetshenziswa futhi ekulungiseleleni izinto ze-ceramic. Ngenxa yezinzuzo zobuchwepheshe be-powder metallurgy, isibe isihluthulelo sokuxazulula inkinga yezinto ezintsha futhi idlala indima ebalulekile ekuthuthukiseni izinto ezintsha.
I-powder metallurgy ihlanganisa ukugaya kanye nemikhiqizo. Ukugaya ngokuyinhloko kuyinqubo ye-metallurgical.Imikhiqizo ye-powder metallurgyngokuvamile zingaphezu kobubanzi bezinto ezisetshenziswayo kanye nensimbi, futhi zivame ukuba yimikhakha ehlukene (izinto ezisetshenziswayo kanye ne-metallurgy, umakhenikha kanye nemishini, njll.) ubuchwepheshe. Ikakhulukazi, ukuphrinta kwesimanje kwe-metal powder 3D kuhlanganisa ubunjiniyela bemishini, i-CAD, ubuchwepheshe be-reverse engineering, ubuchwepheshe bokukhiqiza obugqinsiwe, ubuchwepheshe bokulawula izinombolo, isayensi yezinto ezibonakalayo, nobuchwepheshe be-laser, okwenza ubuchwepheshe bomkhiqizo we-powder metallurgy bube ubuchwepheshe besimanje obuphelele obuhlanganisa iziyalo eziningi.
2.Inqubo yokubumba i-Powder Injection
Indlela yokucubungula ipulasitiki lapho ipulasitiki ifakwe ipulasitiki emgqonyeni wokushisisa womshini wokubumba umjovo bese ijova emgodini wesikhunta esivaliwe yi-plunger noma isikulufu esibuyiselayo ukwenza umkhiqizo. Le ndlela ingacubungula imikhiqizo enobumo obuyinkimbinkimbi, ubukhulu obunembile noma ngokufaka, futhi inokukhiqiza okuphezulu ukusebenza kahle. Iningi le-thermoplastics kanye namanye amapulasitiki ashisayo (njengama-phenolic plastics) angacutshungulwa ngale ndlela. Izinto ezisetshenziselwa ukubumba umjovo kumele zibe ne-fluidity enhle ukuze kugcwaliswe isikhunta ukuze kutholwe umkhiqizo.
Kusukela ngeminyaka yawo-1970, kube nohlobo lokubumba umjovo olunokusabela kwamakhemikhali, olubizwa ngokuthi ukubumba umjovo wokuphendula, oluthuthuke ngokushesha.
3: Umehluko phakathi kwe-powder metallurgy kanye ne-powder injection molding
Njengoba sonke sazi, i-powder metallurgy ubuchwepheshe bezimboni bokulungiselela i-metal powder noma ukusebenzisa i-metal powder (noma ingxube ye-powder yensimbi kanye ne-non-metal powder) njengempahla eluhlaza, ngemva kokwakhiwa nokucwiliswa, ukulungisa izinto zensimbi, izinto ezihlanganisiwe nezinhlobo ezihlukahlukene zemikhiqizo. Kunezinhlobo ezimbili zokubumba izingxenye ze-powder metallurgy: ukubumba kokucindezela okuyimpushana kanye nokubumba komjovo oyimpushana. Uyabazi ubudlelwano babo?
