• Two built-in graphite supporting rods with Max pressure of 100 MPa
• One set of 0.5" (inner diameter) graphite dies is included for immediate use
• Made of high-purity graphite by HIP processing, Max. Load from the hydraulic press is dependent on the die's ID
  • 0.5"ID: Max. 1.26 T (sample pressure 100 MPa)
  • 1.0 ID: Max. 5.06 T (sample pressure 100 MPa, which is optional)
• The graphite pressing die is fragile and consumable. Please click on the picture below to order extra sets. We also provide customized die sets upon customer request at an extra cost
• Mica spacers are included to adjust the height of die sets and insulate heat. Please click on the picture below right to order spares

• Note: The maximum pressure range of graphite dies will vary depending on the inner diameter of the die.
• Please contact MTI if SiC die is required up to 100 MPa. 

Application Notes

• Attention: the gas cylinder must have a two-stage pressure regulator to limit the pressure below 3 psi for safe operation. Click here to learn how the install a gas regulator.

• CE certified
• NRTL certification (UL 1450) is available upon request at an extra cost
