Ceramic Injection Molding

Removing Technological Barriers for Over 100 Years

From the specialized porcelain labware first made in 1914 to modern electronic devices, CoorsTek uses advanced technology, materials, and manufacturing capabilities to remove technological barriers for design engineers worldwide.

Injection Molding

CoorsTek has deep expertise and proven results manufacturing volume production quantities using ceramic injection molding at multiple facilities around the globe. Ideal for the mass production of complex components, injection molding offers significant benefits over conventional methods:

  • Cost-effective techniques
  • High-volume manufacturing runs
  • Production of net or near-net shape parts with tolerances to 0.5%
  • Application-specific materials
  • Flexible design freedom without high labor and manufacturing costs introduced by machining

Injection molding eliminates the need for secondary operations normally required to produce complex geometrical shapes. The more complex the shape, the more advantageous injection molding will be over other fabrication methods.


Optical Design Control

In addition to meeting your physical, thermal, electrical, and chemical performance requirements, CoorsTek components can meet your optical needs with translucent, transparent, reflective, colored, or opaque ceramic materials. 

Superior Materials

CoorsTek offers a broad range of high strength, high performance ceramic materials ideal for complex injection molded designs. CoorsTek engineers work with our customers to select the best material for individual applications.

Custom Finishing & Assembly

CoorsTek provides a complete range of precision finishing options to make your technical ceramic component a functional part or assembly, including metallization, surface treatment, bonding, and specialized testing and packaging.


Ceramic Joining Technology

With ceramic joining technology, CoorsTek introduces even greater design freedom for alumina and zirconia designs with hollow cores or undercuts. Parts are combined using a proprietary process to form a monolithic product without a detectable interface layer, ensuring the join has the same strength and characteristics as the intrinsic ceramic.

Design Assistance

To ensure optimal product performance in your application, CoorsTek engineers offer expert assistance through each phase of the injection mold manufacturing process, from component design and material selection to prototyping and production validation.

General Design Guidelines

  • Thin, uniform cross sections are most suitable.
  • External tapers and undercuts are permissible; internal contours and undercuts are feasible.
  • Flat surfaces are ideal for processing support, but virtually any shape can be accommodated.
