PIM – Powder Injection Molding

Metal and ceramic Powder Injection Molding

Technologies
Application Technology

PIM application

PIM – Powder Injection Molding is a process technology used for mass production to produce parts made of metal (MIM = Metal Injection Molding) or made of ceramics (CIM = Ceramic Injection Molding)  with complex geometries in a high output. PIM is the ideal process to manufacture complex, functional parts in large quantities and with high material requirements.

 

Today, metallurgical powder injection molding is a cost-efficient mass production process to make small- to medium-sized parts ranging from 0.1 to about 300 g in weight. Main fields of application are precision apparatus engineering, measurement and control technology, medical technology, watch and household technologies, the lock and fittings industry, the automotive and the weapons industry.

 

Advantages of the PIM application

  • All metals can be processed, including aluminum, titanium and copper, as well as alloy steel and tungsten.
  • A wide range of ceramic materials can be processed, including oxide ceramics such as aluminum oxide or zirconium oxide, as well as non-oxide ceramics such as nitrides, carbides or borides.
  • Complex geometries can be produced without mechanical downstream finishing.
  • High precision and repeatability
  • High-quality surfaces possible without elaborate downstream finishing

PIM equipment

  • Injection unit with anti-wear coating for screw and barrel
  • Screw with optimized geometry
  • Check valve adapted to feedstock
  • Position control for the screw
  • Longer barrel nozzle with additional heating zone
  • Temperature control inside the feed zone of the barrel
  • Small-volume material hopper with anti-wear coating
  • Program “ejection with open machine door” for manual parts removal
  • Temperature controller for mold tempering
  • Vacuum pump integrated in the machine frame, incl. interface and software
  • “Mold evacuation” program
  • Expert-Coining – injection embossing in combination with ejector or core pull
  • Automation equipment for parts removal (MIM/CIM parts must not be demolded in free fall after injection molding due to the brittleness of the green parts)
