- 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 damage 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, and 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.
- The operator must wear protective goggles.
- You must have a hydraulic pellet press equipped with the Protection Cover, please click the pictures to the left to order.
-
To avoid damaging the die core and sleeve, we strongly recommend pressing powder with a professional laboratory hydraulic press to ensure the evenest pressing interface and uniform pressure force.
- Dies with small diameters (≤12 mm) are more vulnerable to off-center compression, leading to pre-mature top pressing rod failure much below the rated load. Please have top/bottom plates in place and carefully align the die with the centerline of the press machine.

Pressing Die Installation Schematic / Instruction
|
|
|
- Mixing and grinding chemical powder by agate mortar or Ball Mill
- Calcine mixed the powder in a high temp furnace under a suitable temperature
- Crushing and Grinding calcined powder again by mortar or ball mill
- Put calcined powder into the die
- Pressing sample by a pressing machine under suitable pressure
- ( You may use CIP to press again to increase density by about 5 - 10%.)
- Take out the pellet sample from die
- Sintering the pellet under a 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 BNMR for easy mold release. Please click the Pictures1 to order.
- You may order a BN sleeve and die for electric insulation pressing.
