Believe It 28 Mm (1.1") I.d. Dry Pellet Pressing Die - Die-28d-b For Women [fvwCr4xW]

Die-28D-B is a Complete pressing die with I.D. 1.1" (28.00 mm), which is used to to make sample pellets with diameter of 27- 28 mm

SPECIFICATIONS:

Model Number

Die-28D-B

Maximum Load

30 metric Ton (at room temperature)
960 MPa

Material

HRC 60 - 62 hardened steel
Ra 0.08μm highly polished steel
All pressing dies are made by high-stretched carbon steel to achieve high hardness to meet the essential requirements of making ceramic or metal samples. Otherwise, the pressing surface could probably get scratched.

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 damages 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, 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.

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.

Pressing Die Installation Schematic / Instruction

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 into the die
Pressing sample by a pressing machine under suitable pressure
( You may use CIP to press again to increase density about 5 - 10%.)
Take out pellet sample from die
Sintering the pellet under 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 it in a dry place to avoid rusting.
You may consider using BNMR for easy mold release. Please click the picture to order.
