Circular Evacuable Pellet Dies with 50mm Tall Die Chamber

Circular Evacuable Pellet Dies with 50mm Tall Die Chamber

REFLEX Analytical offers custom evacuable pellet die assemblies. Scroll below for pricing and order details for circular sizes ranging from 3mm up to 1 1/8 inches. Larger diameter, customized geometries and dimensions are encouraged and available upon request

Each evacuable pellet die is precision fabricated from high quality hardened 440C stainless steel. The assembly includes a die chamber, one set of anvils(2), a plunger, a evacuable stepped baseplate and an extraction ring to facilitate sample pellet removal. The overall assembled height including the die chamber, stepped baseplate, two anvils and plunger but without sample powder is 104mm. The die chamber only dimensions are 50mm height x 45mm outside diameter with each anvil measuring 10mm thickness (two anvils are typically used for pellet fabrication although one anvil could be used for thicker pellet fabrication).

REFLEX Analytical recommends the review of the chamber height to confirm there is adequate height to fabricate a pellet to the desired pellet thickness. Also ensure there sufficient height between the top and bottom press rams. The pellet dies are commonly used with our series of laboratory presses.

Tungsten carbide anvils are optional and ideal for hard or abrasive powdered sample materials which may tend to mar the surface of stainless steel anvils. Notably, the tungsten carbide transverse rupture strength is 500,000 psi and hardened Stainless Steel is 100,000 psi. Therefore theoretically, tungsten carbide offers 5x the compression strength when compared to hardened stainless steel. A tungsten carbide die chamber and die plunger are also higher cost options.

Other options include a 200°C electrical heating jacket and digital temperature controller; and an optional centered thermocouple port for a customer supplied thermocouple and independent temperature read out. When electrically heated and cooled devices are prohibited, an optional water or oil heating jacket up to 250°C or liquid cooled jacket down to –60°C for use with customer supplied circulating bath is available upon request.

Tips

- allow 6mm minimum to locate the die plunger into the die chamber in order to follow the die chamber wall.

- review of the chamber height to confirm there is adequate height to fabricate a pellet to the desired pellet thickness.

- ensure there sufficient height for the die assembly with sample powder between the top and bottom press rams.

- the evacuable design feature with the use of an oil-less vacuum pump permits easy installation of anvils and plunger without the vacuum resistance normally associated with non-evacuable dies due to the precision fabrication and tight tolerances to mitigate flashing of the powdered sample matrix during pellet fabrication.

230C Heated –60C Cooled Evacuable Pellet Dies

230C Heated –60C Cooled Evacuable Pellet Dies

The Heated and Cooled Pellet Die permits fabricating pellets under high pressures and at temperatures between -76 to +446 degrees F (-60 to +230 degrees C). An ideal solution when electrically heated and cooled devices are prohibited.

Attaching 1/4" tubing from a heated/cooled circulating bath to the die chamber jacket’s inlet/outlet ports provides for integrated liquid heating and cooling capability. Each assembly includes an evacuable port which can also be utilized to introduce a thermocouple couple to accurately monitor and control the die temperature at the sample area prior to evacuation.
