Precision split-type pressing dies for cylindrical powder samples, especially suitable for fine and ultrafine powder compaction
The Cell Lab Split Type Cylindrical Pellet Pressing Die Sets are designed for preparing cylindrical specimens from a wide range of powder materials. Available for sample diameters ranging from 3 mm to 100 mm, these dies support laboratory sample preparation for materials research, powder compaction and analytical testing.
Manufactured from Cr12MoV alloy tool steel with an indenter hardness of HRC 60–62, the die sets are engineered for demanding laboratory pressing applications. The split-type construction facilitates demoulding and helps reduce the risk of damaging fragile or brittle pellets during removal.
These dies are particularly recommended for powders with particle sizes below 400 mesh, or in the micrometre-size range, where conventional pressing dies may be more susceptible to powder blockage. The split design helps improve sample release and supports more convenient preparation of fine and ultrafine powder specimens.
Multiple cavity diameter ranges, cavity depths and die dimensions are available to accommodate different sample sizes and laboratory pressing requirements.

Q1: What sample diameters are available?
The PMK-Y split pressing die series covers sample diameter ranges from 3 mm to 100 mm, depending on the selected configuration.
Q2: Why is a split-type pressing die recommended for ultrafine powders?
The original specifications recommend the split-type die for powders below 400 mesh or in the micrometre-size range to help avoid blockage. Its split construction also facilitates sample removal.
Q3: What material is used to manufacture the die?
The die is manufactured from Cr12MoV alloy tool steel, with an indenter hardness of HRC 60–62.
Q4: What cavity depths are available?
The specified cavity depths are 30 mm, 40 mm, 50 mm, 55 mm and 60 mm, depending on the selected sample diameter range.
Q5: How do I select the correct die configuration?
Select the configuration according to the required pellet diameter, sample quantity, cavity depth and compatibility with your pressing equipment. Confirm the required reference sample size before ordering.
