Powder Forming Process using Passage®/Flow


Step 1 - Compression of Powder
  • Volume change dependent on compressibility of powder and forming pressure
  • Powder move and rotate due to friction
  • Non-uniform stress distribution due to powder movement
Step 2 - Ejection from mold
  • Stress relief and shape spring back

Step 1 - Compression of Powder
