Die-30D is a complete pellet pressing die with 32 mm I.D. is ready for you to make 30 mm diameter target SPECIFICATIONS: Modle Die-32D Die Sleeve Height 2" (50 mm) Outside Diameter 2.44" (63mm) Inside Diameter 32 mm ( 1.259") Whole set pressing die includes One 32 mm I.D. core die made of hardened steel and highly polished with hardness HRC 60 - 62 Ra 0.08μm highly polished steel One steel sleeve for core die protection Two pushing rods (12 mm long and 70 mm long) highly polished and perfectly fitted into die Two steel support plates One steel cylinder for releasing out a sample. Max. Load: 67 metric Ton (at room temperature), or 820 MPa equivalent Pressing die installation schematic Cautions Please must always wear protective goggles during operation !!! The pressing die cannot be used for pressing powder with particle size < 30 microns. 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 3'' Dia. Sieve Set No.200&450 Mesh to separate 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. Application Note You may consider using BNMR for easy mold release. Please click the picture below to order. 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 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 Then, a new material sample is formed! Note: The normal sample height is up to ~25mm. However, this is not a fixed limit and can vary based on the initial packing density of the powder, which is influenced by factors like powder size, shape, and flowability. The final sample height is directly related to how tightly the powder is packed within the die. If the powder is packed tightly enough, 30-40 mm height samples can also be pressed.
