Ceramic Injection Molding (CIM) Manufacturing

Ceramic injection molding represents the fusion of two proven technologies: plastic injection molding and powder metallurgy. This sophisticated manufacturing process enables the cost-effective production of complex ceramic components with exceptional material properties, making it the preferred choice for industries requiring superior hardness, wear resistance, thermal stability, and chemical inertness in intricate geometries.

At Dou Yee Technologies, we specialize in ceramic injection molding using advanced technical ceramics including high-purity alumina, zirconia, toughened composites, and specialty ceramic materials designed to meet the most demanding performance requirements across diverse applications.

What is Ceramic Injection Molding?

Ceramic injection molding is an advanced manufacturing process that transforms fine ceramic powders into precision-engineered components through controlled mixing, injection, debinding, and sintering. The technology combines the geometric freedom of plastic injection molding with the exceptional properties of technical ceramics, enabling the production of complex shapes with features such as undercuts, thin walls, internal cavities, and intricate surface details that would be extremely difficult or cost-prohibitive to achieve through traditional ceramic forming methods.

This process delivers components with superior mechanical properties, excellent dimensional accuracy, and exceptional surface finish, making it ideal for applications demanding durability, precision, and performance in challenging environments.

Ceramic Injection Molding Process

1. Firstly, ceramic powder particles and a binding agent are mixed to create a homogenised mixture. This is known as the Feedstock.
2. Next, the Feedstock is injected into a mold cavity to form a Green Part, which is defined as a part made of powdered material that is compressed and held together with binding material. It then undergoes a binder removal process, through either heat or chemical treatment, to produce a Brown Part.
3. After debinding, the Brown Part undergoes a sintering process at a specific temperature/atmosphere profile, until it hits the targeted density. It is then left to shrink up to 15%.

CIM Materials

With the increase in market demand and customer needs, the range of material that is available in DYT grows steadily in numbers. 

Among them are high purity oxide and carbides, such as Alumina and Zirconia, WC and SiC, as well as toughened Alumina and stabilized Zirconia.

CIM Applications

Ceramic Injection molded parts have applications in various industries, due to their ability to be shaped in complex geometries while maintaining a consistent quality.

Medical

Due to ceramic material properties, CIM components offer high hardness, excellent wear resistance, biocompatibility making it suitable as implants and for use in orthodontic applications.

Consumer Electronics

Typical Normal applications are ceramic capacitors, heat insulators, ferrules for fiber optics.

Automotive

Typical Normal applications are ceramic washers, ceramic battery caps, ceramic seals for E-bike/ Bicycle Braking System.
