Why Powder Injection Molding Simulation?

The technology of Powder Injection Molding (PIM) originated in 1973. In the process, finely-powdered metal or ceramic is mixed with a measured amount of binder material to compose a feedstock. The feedstock is capable of being shaped as a part through a process of injection molding, de-binding, and sintering. The part surfaces has such high flatness as if it’s been through polishing processing. This molding process allows complex parts to be molded in a single operation and in high volume, widely applied in various industries and applications.

Challenges

  • Final quality of surface appearance
  • Efficiently minimize the effects of volumetric shrinkage, warpage, and black lines (uneven powder concentration), achieving the need of high sintered product quality standard
  • Black-line phenomenon that is associated with power-binder separation and the resultant low powder concentration areas

What Can Moldex3D Do?

  • Visualize the flow behavior of the feedstock consisted of powder and binder
  • Predict potential molding defects, such as warpage or Black-lines
  • Evaluate the effects of shear rate on powder concentration
  • Evaluate the optimal mixing portion of powder and binder
  • Calculate the feedstock properties
  • Optimize process conditions, such as temperature or filling speed
