Pellet Press Die Set includes: Die sleeve, plunger rod, 2 x spacers, release ring and base plate.

8 mm Pellets Dies have a range of applications. as with 6 mm die sets, 8 mm pellet dies are commonly used for making KBr pellets for FTIR analysis, in which small quantities of powders are mixed with Infrared-transparent KBr (Potassium Bromide) powder before pressing into a pellet and transferring into the FTIR.

High compressive stresses can be applied to powders in the 8 mm pellet die sets using low pressing forces. Whilst this can be useful for quickly making pellets, always stay under the recommended load and make sure you stay safe. If you don't have a hydraulic press, for the lower diameter die sets, pressing force can be applied manually with a lever press or arbor press. If you need a slightly difference size for your application.

Die made of hardened tool steel (Rockwell hardness >C60) for long lasting trouble free performance. Sleeve is polished to high tolerances to allow the hardened tool steel plunger to slide through perfectly. Plunger and spacers are made from high yield strength steel, machined and polished to high tolerance for the perfect fit. Interior surfaces ground to mirror-like finish.
