Die-12D-B is a 1/2" I.D. pressing die set for making 12.7 mm diameter sample pellets. The pressing die is made of high-strength and polished carbon steel to achieve high hardness for meeting the essential requirements of making ceramic or metallic samples.

SPECIFICATIONS:

Maximum Load
(at room temperature)		 12 metric Ton
930 MPa
Material HRC 60 - 62 hardened steel 
Ra 0.08 μm highly polished steel
All pressing dies are made of high-strength carbon steel to achieve high hardness to meet the essential requirements of making ceramic or metallic samples. Otherwise, the pressing surface could probably get scratched.
Max. Working Temperature 280 °C
Material Requirement
  • 32-75 Microns
  • Do not use this die set for pressing powder with a particle size of 30 microns or smaller; Small particles may slip into the gap of the die parts and damage the sleeve during the compression.
  • Ball mill or ground the powder 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.
  • For pressing sticky metal powders such as Al, Mg, and 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. 
Package Content
  • One pressing die sleeve
  • One top-pressing rod
  • One bottom-pressing rod
  • One support plate
  • One die kit container
Safety Precaution
  • To avoid the risk of accidents and damage to the Pressing Die, please read these instructions carefully before installation and before using it for the first time.
  • Read the manual, especially the die installation schematic, before the operation.
  • Do not press flammable, explosive materials.
  • The operator must wear protective goggles.
  • You must have a hydraulic pellet press equipped with the Protection Cover, please click the pictures to the left to order.
  • To avoid damaging the die core and sleeve, we strongly recommend pressing powder with a professional laboratory hydraulic press to ensure the evenest pressing interface and uniform pressure force.
  • Dies with small diameters (≤12 mm) are more vulnerable to off-center compression, leading to pre-mature top pressing rod failure much below the rated load. Please have top/bottom plates in place and carefully align the die with the centerline of the press machine.
Pressing Die Installation Schematic / Instruction
  1. Mixing and grinding chemical powder by agate mortar or Ball Mill
  2. Calcine mixed the powder in a high temp furnace under a suitable temperature
  3. Crushing and Grinding calcined powder again by mortar or ball mill
  4. Put calcined powder into the die
  5. Pressing sample by a pressing machine under suitable pressure
  6. ( You may use CIP to press again to increase density by about 5 - 10%.)
  7. Take out the pellet sample from die
  8. Sintering the pellet under a suitable temperature
Application Notes
  • Use ethanol to clean the pressing die before and after use every time
  • Use anti-rust oil after the operation and store the kit inside the original box in a dry place to avoid rusting.
  • You may consider using BNMR for easy mold release. Please click the Pictures1 to order.
  • You may order a BN sleeve and die for electric insulation pressing.
