Product Description
This low profile die set is for making small diameter 0.07 inch (2 mm), short length <0.2 inch (<6mm) pellets. The compact design and high strength heat-treated stainless steel means a higher force can be applied while pressing reducing the chance of plunger breakages.
Features of this die set are:
- Compact Design: Built for High Loads
- High Strength Stainless Steel: Heat treated to 160,000 psi
- Built in ejector sleeve
- Heatable up to 250°C (482°F)
Low profile pellet press die sets include:
- 1pc Die sleeve
- 1pc Plunger rod
- 1pc Base plate
Unlike our standard sets, ejector prongs are designed as part of the die sleeve, rather than a separate part. When using high forces you want a small amount of unsheathed plunger to prevent bucking of the plunger, so I) we keep the plunger short and ii) there are no spacers in the low profile die sets. These sets are made from stainless steel so can be heated to 250 °C (482°F) during pressing.
See video below showing how this low profile die set works.

High Strength Heat Treated Steel
Sleeve is ground to high tolerances to allows the plunger to slide through perfectly. Interior surfaces ground to a mirror-like finish (Ra=0.1).
These are some of the smallest die we stock. You typically DO NOT NEED HIGH LOADS FOR GOOD PELLETS – High loads do not equal better pellets. At small diameters, you only need a small load (around 100 - 2000 lb!) for very high stresses on plunger and the powder. We do not suggest using with a hydraulic press which does not have an accurate read out for low forces. Do not use this die with a big, heavy press - you can easily exceed the yield stress of the steel. Think before hand, if you are close to being able to break steel then you are probably giving enough load to push powder together. You can even push down hard with your hand or tap it with a mallet to create sufficient force for compaction.
