Ekukhiqizeni, ukunemba kobukhulu nokuma kwemikhiqizo ye-powder metallurgy kuphezulu kakhulu.Ngakho-ke, ukulawula ukuminyana kanye nokushintsha kobukhulu bezinto ezihlangene ngesikhathi sokucula kuyindaba ebaluleke kakhulu.Izinto ezithinta ukuminyana nokushintsha kobukhulu bezingxenye ezisikiwe yilezi:

1. Ukuncipha kanye nokususwa kwezimbotshana: Ukucweba kuzobangela ukuncipha nokususwa kwezimbotshana, okungukuthi, ukunciphisa umthamo womzimba osindisiwe.

2. Igesi ehlanganisiwe: Phakathi nenqubo yokwenza umshini wokunyathelisa, ama-pores amaningi avaliwe avaliwe angase akhiwe ku-compact, futhi lapho umthamo we-compact ushiswa, umoya kulawa ma-pores angawodwa uzokhula.

3. Ukusabela kwamakhemikhali: Amanye ama-elementi amakhemikhali endaweni ehlanganayo kanye ne-sintering atmosphere asabela ngenani elithile lomoya-mpilo ekuhlanganiseni kwempahla eluhlaza ukuze akhiqize igesi noma ashibilike noma ahlale ekumpintsheni, okubangela ukuminyana ukuba kushwabane noma kwandise.

4. Ingxubevange: Ingxubevange phakathi kwezimpushana zezinto ezimbili noma ngaphezulu.Uma ingxenye eyodwa incibilika kwenye ukuze yakhe isixazululo esiqinile, i-lattice eyisisekelo ingase inwebe noma inciphe.

5. I-Lubricant: Uma i-powder yensimbi ixutshwa nenani elithile lokuthambisa futhi icindezelwa ku-compact, ezingeni lokushisa elithile, okokugcoba okuxubile kuzoshiswa, futhi i-compact izoshwabana, kodwa uma ibola, into eyigesi ayikwazi. finyelela ebusweni be-compact..umzimba we-sintered, okungase kubangele ukuhlangana kwande.

6. Isiqondiso sokucindezela: Phakathi nenqubo ye-sintering, usayizi we-compact uyashintsha perpendicularly noma ngokuhambisana nesiqondiso sokucindezela.Ngokuvamile, izinga lokushintsha kobukhulu obume mpo (radial) likhulu.Izinga lokushintsha kwe-dimensional ku-parallel direction (i-axial direction) lincane.
