Material Requirement
  • 32-75 Microns
  • Do not use this die set for pressing powder with a particle size of 30 micron or smaller; Small particles may slip into the gap of the die parts and damages the sleeve during the compression.
  • Ball mill or ground the powder to the size of 32~75 microns powder before pressing. Please consider using the 3'' Dia. Sieve Set No.200&450 Mesh to separate the 32~75 microns particles from the powder clumps.
  • For pressing sticky metal powders such as Al, Mg, Zn, it is necessary to use dry or alcohol-based tool lubricant to lubricate the die and sleeve set to reduce friction during the compression.

Pressing Die Installation Schematic / Instruction

  1. Mixing and grinding chemical powder by agate mortar or Ball Mill
  2. Calcine mixed the powder in a high temp furnace under suitable temperature
  3. Crushing and Grinding calcined powder again by mortar or ball mill
  4. Put calcined powder into the die
  5. Pressing sample by a pressing machine under suitable pressure
  6. Take out pellet sample from die
  7. Sintering the pellet under suitable temperature
Application Notes

    • Use ethanol to clean the pressing die before and after use every time
    • Use anti-rust oil after the operation and store the kit inside the original box in a dry place to avoid rusting.
