Cell Lab Anti-cracking Pressing Die Sets [5 mm, 10 mm & 40 mm]

Cell Lab Anti-cracking Pressing Die Sets [5 mm, 10 mm & 40 mm]

Specially designed die sets to reduce pellet cracking during powder compaction

General Description

Cell Lab Anti-cracking Pressing Die Sets are engineered to minimise the risk of cracking in pressed pellets, providing researchers and manufacturers with higher reliability in sample preparation. Constructed from Cr12MoV alloy tool steel with indenter hardness of HRC60–62, these dies are suitable for both laboratory and industrial use.

Available in 5 mm, 10 mm, and 40 mm diameters, the series supports a wide range of applications in pharmaceuticals, materials science, analytical chemistry, and powder metallurgy. Their specialised design ensures uniform pressure distribution and enhanced pellet integrity, making them ideal for fragile or brittle powder systems such as halide salts and ceramic powders.

FAQ

Q1: How does the anti-cracking design work?
It applies optimised pressure distribution to reduce stress concentration, minimising pellet breakage.

Q2: Which materials benefit most from these dies?
Fragile powders such as KBr, halide salts, ceramics, and brittle compounds.

Q3: Can these dies be used with high pressures?
Yes. They are designed for standard laboratory press loads, but avoid exceeding manufacturer recommendations.

Q4: How should the dies be maintained?
Clean and dry after each use; lightly oil the surface if storing for long periods to prevent rust.

Q5: Are custom cavity sizes available?
Yes. Cell Lab offers custom anti-cracking pressing dies on request.
