Instruction
Cautions	WARNING: Operator must wear protection goggle. The pressing die cannot be used for pressing powder with particle size LESS THAN 30 micron. Small particles may slip into the gap between pushing rod and steel sleeve and cause damages to the sleeve during the compression. Ball mill or ground the powder and 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. Please use ethanol to clean the pressing die every time before use and store it in a dry place with anti-rust oil after operation to avoid rusting. All pressing dies are made by high-stretched carbon steel to achieve high hardness to meet 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 to press powder with a professional laboratory hydraulic press to ensure the evenest 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 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 in to 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
