200-Ton Automatic Tablet Press Empowering Advanced Ceramic Research at NUS

As a long-term strategic partner, National University of Singapore (NUS) has been deeply engaged in the research of ultra-high-temperature ceramic materials, particularly in cutting-edge areas such as oxide eutectic ceramics for aerospace applications. The university undertakes multiple national-level research projects and serves as an important practical training base for materials science and engineering students.

With the continuous advancement of high-hardness and ultra-high-temperature ceramic research, the limitations of existing pressing equipment became increasingly evident. The previous tablet press system suffered from:

• Insufficient tonnage capacity
• Low pressure regulation accuracy
• Uneven powder compaction
• High crack and pore defect rates

These issues directly affected ceramic density, structural integrity, and experimental reproducibility, creating bottlenecks in both scientific research and student training. To overcome these challenges, NUS required a high-precision, large-tonnage, intelligent tablet press system capable of supporting both advanced research and teaching applications.
