Annulus Dies and Toroidal Dies
REFLEX Analytical offers custom non-evacuable annulus pellet dies or commonly referred to as a toroidal die, ring pellet die, donut die or center hole pellet die assemblies. Customized dimensions are encouraged and available upon request.
Sizes range up to a maximum 50mm pellet outside diameter to minimum 1mm inside diameter. Click on the above representative image to enlarge and become familiar with each component. Contact REFLEX Analytical with the die specification your application requires.
Each pellet die is precision fabricated from high quality tool steel or optional hardened 440C stainless steel. The assembly includes a die chamber, die base, one set of outside dimension with center inside dimension anvils(2), a center inside dimension pin, a pellet plunger, a center pin plunger and extraction ring to facilitate sample pellet removal. The die chamber dimensions for pellet die sizes up to 50mm outside diameter are 50mm die chamber height x 69mm die chamber outside diameter with each anvil measuring 10mm thickness (two anvils are used for pellet fabrication). The overall assembled height including the die chamber, stepped baseplate, two anvils and plungers but without sample powder is 103mm. The pellet dies are commonly used with our series of laboratory presses.
REFLEX Analytical recommends the review of the chamber height to confirm there is adequate height to fabricate a pellet to the desired pellet thickness. If required, the chamber height and plunger height can be adjusted accordingly. Offer request for quotation and indicate the required height. Furthermore, please ensure there sufficient height between the top and bottom press rams.
Tungsten carbide anvils are optional and ideal for hard or abrasive powdered sample materials which may tend to mar the surface of tool steel or 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 plungers are also higher cost options.
