How to Choose the Right CIM Materials?

Selecting suitable materials is critical for ceramic injection molding. Consider key factors like part function, service environment, mechanical requirements, quality needs, complexity, secondary processing steps, and budget. Our experts can help determine your application's optimal ceramic material composition and binder system.

  • Evaluate application requirements: Consider part function, operating environment, loads, service temperature, electrical properties needed, etc. This determines material property needs.

  • Assess mechanical performance needs: Hardness, strength, fracture toughness, wear, and corrosion resistance required. Materials like alumina or zirconia are tough.

  • Determine complexity of part design: Simpler geometries allow higher filler loadings and easier molding. Complex parts may need optimized binder formulation.

  • Consider finishing processes needed: Secondary machining and surface finishing impact material choices. Avoid abrasive fillers if polishing is required.

  • Evaluate cost considerations: Material choice impacts raw material, tooling, equipment, and labor costs.

  • Leverage material supplier expertise: Reputable suppliers can provide guidance on materials tailored to the application.

CIM Material Classification

Ceramic injection molding utilizes a wide range of technical ceramic materials to produce components with specific properties and performance. We classify CIM materials into categories like oxides, non-oxides, ferrites and more based on composition and characteristics to guide materials selection for different applications.

Ceramic injection molding (CIM) utilizes a diverse range of technical ceramic materials that can be classified into the following major categories:

  • Oxide ceramics: Oxide ceramics constitute a major class of ceramic materials used in injection molding applications. They are composed of metallic elements combined with oxygen, such as alumina, zirconia, and beryllia. Oxide ceramics offer exceptional hardness, wear resistance, and high-temperature stability.

  • Non-oxide ceramics: Non-oxide ceramics are ceramic materials that do not contain metallic oxides as their major components. This class includes silicon carbide, silicon nitride, boron carbide, and aluminum nitride. Non-oxide ceramics exhibit high strength, fracture toughness, and excellent thermal shock resistance even at extremely high temperatures..

  • Specialty ceramics: Specialty ceramics include advanced materials engineered for highly specific applications and properties like biocompatibility, piezoelectricity, and more. Our specialty ceramics portfolio includes unique materials such as piezoceramics, bioactive ceramics, glass ceramics, and nanoscale ceramics with tailored functionalities.

Choosing the right ceramic injection molding material requires evaluating key considerations like mechanical, thermal, electrical, and chemical properties needed, material costs, part geometries, secondary processing needs, rheological behavior for molding, and toxicity. Our experts can help select the ideal ceramic composition tailored to your application.
