Combustion Driven Compaction (CDC)What is Combustion Driven Compaction (CDC)?

  • Powdered metal or powdered ceramic material is placed in a suitable shaped die
  • A pressurized mixture of natural gas and air is introduced into the combustion chamber
  • The mixture is then ignited to drive a piston (ram)
  • A punch is driven downward by the piston into the metal powder, transferring energy into and compacting the powder
  • CDC converts chemical energy directly to mechanical energy for high efficiency!
  • The entire process is smooth and continuous, keeping constant pressure on the part at all times
  • The piston is never allowed to accelerate before it contacts the powder this avoids introducing shockwaves in the powder
