Steps to Make Sample Pellet |
• Mixing and grinding chemical powder by agate mortar or Ball Mill.- • Calcine mixed the powder in a high temp furnace under 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.
- • Take out pellet sample from the die.
- • Sintering the pellet under suitable temperature.
- • The sample is ready.

| Operation Instructions |  |
Cautions
 |
• Must always wear protection goggles during operation.- • The pressing die cannot be used for pressing powder with a particle size < 30 microns. Small
particles may slip into the gap between pushing rod and steel sleeve and cause damages to
the sleeve during the compression. Ball mill and sieve the powder and apply only the 32~75
microns powder to the pressing die to avoid the damages. - • Please consider using the 3'' Dia. Sieve Set No.200&450 Mesh to separate the 32~75 microns
particles from the powder clumps. Please clean the mould via ethanol after the completion of
each experiment. - • Please use ethanol to clean the pressing die every time before use.
- • Store it in a dry environment with antirust oil after operation to avoid rusting on the surface.
- • To avoid damaging the die core and sleeve, we strongly recommend you use the professional
laboratory hydraulic presses which ensure the most even pressing interface and uniform
pressure force. - • 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. - • Do not press flammable, explosive materials.
