Powder injection molding

Complex metal and ceramic molded parts

Powder injection molding (PIM) enables the cost-effective series production of durable, precision metal (MIM) or ceramic (CIM) parts. The major benefit of the multistage process: freedom of shape. With us as your partner, you can successfully interlink all process steps.

 

We generally place great value on reproducible, flawless injection molding production. That is why, in principle, all ALLROUNDER injection molding machines are suitable for powder processing. We create complete solutions, precisely adapted to the applications using integrated peripherals and automation solutions.

Highlights

  • Exploit all the options available to you in the ARBURG PIM laboratory - from the preparation of feedstock through to sintering
  • Large selection of powder materials: in addition to the oxide ceramics and steels, hard and precious metals, as well as cermets can also be used.
  • Customer-specific development and testing of feedstocks (powder-binder mix)
  • High-quality, reproducible series production with ALLROUNDER injection molding technology
  • Wide range of equipment details for efficient powder processing, e.g. highly wear-resistant MIM or CIM cylinder module and extended PIM nozzles

Process technology

PIM laboratory
Our PIM laboratory affords you the opportunity to test all key process steps under practical conditions: from feedstock development and testing through to preparation and injection molding, debinding and sintering of the molded parts. Furthermore, detailed consultation is available from our specialists.

Application examples

Smartphone back
Manufacturing smartphone backs by means of powder injection molding with dynamic mold temperature control is a production-efficient alternative to machining. A hydraulic ALLROUNDER featuring PIM equipment and the Catamold 17-4 Plus feedstock from BASF can be used, for example.

Intermediate lever
Using metal powder injection molding (MIM), you can produce high-strength parts with complex geometries, such as those required for automotive valve actuation systems in engines. The intermediate lever, which is produced fully automatically, is one of the first ever functional MIM components ever to be installed in a combustion engine.

Ferrule
Ceramic ferrules connect optical fiber bundles for the transmission of data. The key here is the high-precision molding of the through-hole, measuring just 0.125 mm. Tolerances of +/- 10 µm are achieved with powder injection molding. This is achieved by means of ARBURG's position-regulated screw.
