Kwimveliso, ukuchaneka kwedimensional kunye nokumila kwe powder metallurgy iphezulu kakhulu.Ke ngoko, ukulawula ingxinano kunye notshintsho lwedimensional ye-compact ngexesha lokuntywila ngumba obaluleke kakhulu.Izinto ezichaphazela ingxinano kunye notshintsho lwe-dimensional yamalungu adityanisiweyo zezi:

1. Ukunciphisa kunye nokususwa kwee-pores: I-Sintering iya kubangela i-shrinkage kunye nokususwa kwee-pores, oko kukuthi, ukunciphisa umthamo womzimba we-sintered.

2. I-gesi edibeneyo: Ngethuba lenkqubo yokwenza i-press, ezininzi ii-pores ezivaliweyo ezivaliweyo zinokuqulunqwa kwi-compact, kwaye xa umthamo we-compact ushushu, umoya kule mibhobho yodwa uya kwanda.

3. Ukusabela kweekhemikhali: Ezinye izinto zeekhemikhali kwi-compaction kunye ne-sintering atmosphere zisabela ngomlinganiselo othile we-oksijini kwindawo ekrwada ekrwada ukuvelisa irhasi okanye i-volatilize okanye ihlale ekuxinaniseni, okubangela ukuba ukuxinana kunciphe okanye kwande.

4. Ingxubevange: Umxube phakathi komgubo wezinto ezimbini okanye ngaphezulu.Xa enye into inyibilika kwenye ukuze yenze isisombululo esiqinileyo, i-lattice esisiseko inokwanda okanye iyancipha.

5. I-Lubricant: Xa umgubo wesinyithi uxutywe kunye nomlinganiselo othile we-lubricant kwaye ucinezelwe kwi-compact, kwiqondo elithile lobushushu, i-lubricant edibeneyo iya kutshiswa, kwaye i-compact iya kuncipha, kodwa ukuba iyabola, i-gaseous substance ayikwazi. ukufikelela kumphezulu we-compact..umzimba we-sintered, onokubangela ukuba i-compact yande.

6. Ulwalathiso olucinezelayo: Ngethuba lenkqubo ye-sintering, ubungakanani be-compact buguquka nge-perpendicularly okanye ngokuhambelana nolwalathiso olucinezelayo.Ngokubanzi, umyinge othe nkqo (radial) wokutshintsha ubungakanani mkhulu.Izinga lokutshintsha kwe-dimensional kwi-parallel direction (i-axial direction) incinci.
