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.

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.

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 it in a dry place to avoid rusting.
- • You may consider using EQ-BNMR for easy mold release. Please click the picture to order.
