Ceramic Injection Molding

Exploring the world of new material technologies

Ceramic Injection Molding is an innovative new process at HI-TECH SYSTEMS & ENGINEERS under a six sigma controlled environment. The CIM process gives production engineers and product designers more versatility in the use of ceramics as an alternative material – with higher productivity, lower manufacturing costs and improved product performance. CIM is also a good option, when you need to replace plastic and metal components that fail to perform adequately.

The inherent advantages of the CIM process place a focus on quality and precision, working closely with customer specifications and a closely monitored process that meets these requirement. The low cost and complex designing capabilities of CIM Technology offers higher economies of scale and cuts manufacturing time by eliminating elaborate machining and finishing.

How Ceramic Injection Molding works

• 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 HI-TECH SYSTEMS & ENGINEERS, 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.
