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.


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 protection goggle.
  •      •  You must have a hydraulic pellet press equipped with the a 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. 1.Mixing and grinding chemical powder by agate mortar or
       Ball Mill
  2. 2.Calcine mixed the powder in a high temp furnace under
       suitable temperature
  3. 3.Crushing and Grinding calcined powder again by mortar or
       ball mill
  4. 4.Put calcined powder into the die
  5. 5.Pressing sample by a pressing machine under suitable
       pressure
  6. 6.Take out pellet sample from die
  7. 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.
