Application Notes
  • To get the better density of samples, please considering using a cold isostatic press (CIP)
  • Small particles may slip into the gap between the pushing rod and steel sleeve and cause damages to the sleeve during the compression. We recommend using 32~75 microns powder to avoid damages.
  • Please consider using the 3'' Dia. Sieve Set No.200&450 Mesh to get 32~75 microns particles  
  • Please use alcohol to clean the pressing die every time before and after use
  • Store it in a dry place with antirust oil after the operation to avoid rusting.
  • For pressing sticky metal powders such as Al, Mg, Zn, it is necessary to use dry or alcohol-based lubricant to lubricate the die and sleeve set to reduce friction during the compression. 
  • Please must always wear protective goggles during the operation !!!
  • Pressing Dies are consumable products and are not covered by MTI's warranty.
