Aluminum oxide (Al2O3) is a type of ceramic, known for its high mechanical hardness, electrical resistivity, and thermal conductivity. It possesses strong and stiff properties, as well as good resistance to wear and corrosion, thermal stability, low dielectric constant and loss tangent, low thermal expansion, and low weight. This makes it suitable for various applications such as technical ceramics, electronic components, and medical products. Ceramic Injection Molded (CIM) Alumina demonstrates properties similar to pressed and sintered samples. The most commonly used material for feedstock preparation is Al2O3 powder with 99.7% purity.

Below is the process of Ceramic injection Molding:

CIM Process
  1. Compounding: The feedstock preparation often involves the use of a multicomponent binder such as polypropylene, paraffin wax, and stearic acid.
  2. Molding & Debinding: Following the injection molding procedure, the next step is debinding, during which the samples undergo a debinding process.
  3. Sintering: Sintering is carried out in air at temperatures exceeding 1600°C. After this step, it is crucial to inspect all samples to ensure that they are free from any visual defects.

Ceramic Injection Molded (CIM), Alumina is the most widely used injection molded ceramic material. CIM Alumina components have high surface finish quality even with extremely complex geometries.

  • They have high hardness end mechanical strength, high wear and corrosion stability and good electrical insulation.
  • CIM alumina components are also dimensionally stable and able to withstand high working temperatures.
  • Since they combine good mechanical properties with low specific weight,
  • CIM Alumina components are being used in engineering (sensor covers, sensor tubes, micro electrodes for ultrasonic welding, etc.), textile industry (textile thread guides, wire guides, etc.),
  • Medical and dental applications (orthodontic brackets, dental implants, prosthetic replacements, etc.),
  • Watches (precision watch gears), metallurgy (ceramic casting cores),
  • Automotive components (valve components), electrical components (microwave dielectric components), office equipment (inkjet printheads), etc.
  • Recent research activities proved that CIM Alumina has a great potential because nowadays it is a commonly used material in both micro-CIM and 2C-CIM technology – advanced CIM technologies.
