EPSI Tri-Axial Cold Isostatic Press from China
EPSI's tri-axial cold isostatic press uses three-dimensional pressure application for producing large-diameter semiconductor ceramic tubes and rods from powders. It achieves 200-600 MPa hydrostatic compaction at room temperature, essential for consistent microstructures in GaAs device substrates. HTS 8479.83.00.00 covers this specialized isostatic compaction equipment.

Import Tips
• Provide engineering drawings showing tri-axial pressure chamber design for classification proof
• Certify for cleanroom compatibility if destined for semiconductor fabs; affects documentation
