Material Requirement
  • 32-75 Microns
  • Do not use this die set for pressing powder with a particle size of 30 microns 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. 
Package Content
  • One pressing die sleeve
  • One top pressing die
  • One bottom pressing die
  • One support plate
  • One die kit container
Safety Precaution
  • To avoid the risk of accidents and damage to the Pressing Die, please read these instructions carefully before installation and before using it for the first time.
  • Read the manual, especially the die installation schematic, before the operation.
  • Do not press flammable, explosive materials.
  • The operator must wear a protection goggle.
  • You must have a hydraulic pellet press equipped with the Protection Cover, please click the pcitures to the left to order.
  • To avoid damaging the die core and sleeve, we strongly recommend to press powder with a professional laboratory hydraulic press to ensure the evenest pressing interface and uniform pressure force.
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.
  • You may consider using EQ-BNMR for easy mold release. Please click the picture below to order.
  • Pressing Dies are consumable products and are not covered by MTI's warranty.
