    Cautions
    • Please 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. ( Pic. 1)
    • You may use BN coating as mould release (Pic 2)
