Precision Heated Pellet Dies for Laboratory Powder Compaction
The Cell Lab Heating Pellet Pressing Die Set series is engineered for compressing powders into cylindrical pellets under controlled temperature conditions. Made from hardened alloy steel (AISI D2, equivalent to JIS SKD11 / GB Cr12MoV / DIN 1.2379), these dies provide high hardness (Rc 60–62) and durability for laboratory applications.
Available in diameters from 0.25" (6.35 mm) to 1" (25.4 mm), with heating ranges up to 300 °C or 500 °C, the die sets are ideal for temperature-sensitive powders such as polymers, resins, and materials prone to phase transition. They are also widely used in battery R&D, ceramics, minerals, and pharmaceuticals.
Optional cooling stages are available at additional cost. Other diameters and geometries can be customised upon request.
Multiple sizes – Available in 0.25", 0.4", 0.5", and 1" diameters.
Heating capability – Models support heating up to 300 °C or 500 °C, with rates of 5–10 °C/min.
High hardness alloy steel – Constructed from AISI D2 / SKD11 tool steel for durability and wear resistance.
Temperature-sensitive material testing – Suitable for polymers, resins, and phase-transition powders.
Customisable options – Cooling stage and special die geometries available upon request.

Q1: What sizes are available?
A: Standard diameters include 0.25", 0.4", 0.5", and 1". Custom sizes can be manufactured upon request.
Q2: What is the maximum heating capability?
A: Models are available with either 300 °C or 500 °C heating range.
Q3: Can these dies handle fine powders below 50 microns?
A: It is not recommended to press powders smaller than 50–100 microns, as they may slip into die gaps and damage the sleeve.
Q4: Is a cooling stage included?
A: No. Cooling stages are optional and can be purchased separately.
Q5: Are pressing dies covered under warranty?
A: Pressing dies are consumables; only manufacturing defects are covered. Damage from misuse, rust, or fine particle intrusion is excluded.


You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly.
