Cautions |
- Please must always wear protective goggles during operation !!!
-
The pressing die cannot be used for pressing powder with particle size < 30 micron. Small particles may slip into the gap between the 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 to seperate the 32~75 microns particles from the powder clumps. Please clean the mold via ethanol after the completion of each experiment.
- Please use alcohol to clean the pressing die every time before use and store it in a dry place with antirust oil after the operation to avoid rusting on the surface, because all pressing dies are made by high-stretched carbon steel for achieving high hardness to meet the essential requirements of making ceramic or metal samples. Otherwise, the pressing surface could probably get scratched.
- To avoid damaging the die core and sleeve, we strongly recommend you use the professional laboratory hydraulic pressers 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.

Steps to make sample pellet |
- Mixing and grinding chemical powder by
- Calcine mixed the powder in a high temp furnace under suitable temperature
- Crushing and Grinding calcined powder again by
- Put the calcined powder into the die
- Pressing sample by a pressing machine under suitable pressure
- Take out pellet sample from die
- ()
- Sintering the pellet under suitable temperature
- Then, a new material sample is formed!ing Oven
