I-Powder Injection Molding (PIM) iyinqubo yokukhiqiza ephumelelayo, enembayo ehlanganisa insimbi, i-ceramic, noma impushana yepulasitiki nezinto eziphilayo futhi ifakwa esibunjeni lapho izinga lokushisa liphezulu nokucindezela. Ngemuva kokuphulukisa nokucwilisa, izingxenye ezinomthamo omkhulu, amandla aphezulu nokunemba okuphezulu zingatholakala.
Ama-Pim angakhiqiza ubujamo bejiyomethri obuyinkimbinkimbi kunezinqubo zokukhiqiza zendabuko, njengokuphonsa, ukuhlanganisa imishini noma ukupholisa, futhi kungenziwa ngokushesha futhi ngamanani amakhulu. Ngakho-ke, isetshenziswa kabanzi kwezezimoto, kwezokwelapha, kwezokuxhumana nakweminye imikhakha.
Kubalulekile ukuqaphela ukuthi ngesikhathi senqubo ye-PIM, ukunakwa okukhethekile kufanele kukhokhwe emininingwaneni yokuxuba i-powder kanye nenqubo yokujova ukuze kuqinisekiswe ikhwalithi yomkhiqizo wokugcina.
Inqubo yokubumba umjovo we-powder ihlukaniswe ngezinyathelo ezilandelayo:
- Ukuxuba powder:insimbi, i-ceramic, ipulasitiki nezinye izinto ngemuva kokwelashwa kwangaphambili, ngokwengxenye ethile yokuxuba.
- Ukubumba umjovo:I-powder ehlanganisiwe kanye ne-organic matter ijojowe esikhunjeni ngomshini womjovo, futhi ukubunjwa kwenziwa ngaphansi kokushisa okuphezulu nokucindezela. Inqubo ifana nokubumba umjovo wepulasitiki, kodwa idinga umfutho ophakeme womjovo kanye nezinga lokushisa.
- Ukudiliza:Ngemva kokupholisa umkhiqizo oqediwe, uwususe esikhunjeni.
- Ukwelashwa kokwelapha:izingxenye zepulasitiki ezakha, zingelapheka ngokushisa; Ezingxenyeni zensimbi noma ze-ceramic, kudingeka zikhishwe i-wax kuqala, bese ngokusebenzisa i-sintering ukuze kuzuzwe ukuminyana okuphezulu, izidingo zamandla aphezulu.
- Ukwelashwa kwendawo:okuhlanganisa ukugaya, ukupholisha, ukufutha nezinye izinqubo zokuthuthukisa ikhwalithi yomkhiqizo nokuthuthukisa izinga lobuhle.
- Iphakheji yokuhlola: Hlola futhi ubuke izingxenye ezifanelekayo, iphakheji bese uyithumela ekhasimendeni ukuze lisetshenziswe.
Ngamafuphi, inqubo ye-PIM inika amandla ukukhiqizwa kwenqwaba okuphumelelayo nokunembayo, kodwa ukulawulwa okuqinile kwemingcele kuyadingeka esinyathelweni ngasinye ukuze kuqinisekiswe ikhwalithi yomkhiqizo wokugcina.
