- Fine Ceramic powder is mixed with a polymer binder. This mixture is granulated to form “feedstock”
- Feedstock is heated to form viscous slurry and injection molded to form “green” part.
- Part of the binders are removed through solvent de-binding to get “brown” part.
- The brown part is densified through sintering to get ‘finished’ part.
Quality Systems and certifications for CIM
At Indo-MIM, quality management is not just a regulatory mechanism but engineered into the system – providing continual improvement, emphasizing defect prevention and reducing variation and waste. Quality assurance is also a key measure of discussion with customers – to be understood and executed by every member of the team, for complete customer satisfaction. Our facility is certified with ISO 9001:2015 and ISO 14001:2015
Material solutions under CIM for a variety of applications
Indo–MIM provides special purpose material options to help clients derive optimal benefits in terms of process efficiency and other related benefits
Alumina (92%, 96% and 99.7%): For parts that require good wear and corrosion resistance, such as electrically insulating bodies, chemical operations, industrial machinery and the vacuum industry. Maximum temperatures from 1200-1600°C.
Zirconia (YSZ): For applications where the strength of alumina is insufficient and is available in white and black. Maximum temperatures – up to 1200° C.
Zirconia toughed Alumina (ZTA): For parts with excellent surface quality requirements and reproduction of fine details. It delivers good wear resistance and high strength for biomedical applications, microengineering, and fiber optics. Maximum temperatures – up to 1200° C

Current application areas for Ceramic Injection Molding
When you integrate the benefits of ceramic materials with the process advantages of injection molding, you derive highly complex geometries with minimal machining. You also reduce part count and assembly time. Ceramic injection molding (CIM) is now the recommended option for durable, demanding parts that require high resistance to heat, corrosion and wear. It offers the advantages of repeatability and consistent quality – with proven statistical process control.
