Explore Our BackgroundTypical Components
Explore materials, geometry and manufacturing features through four component categories.
Ultra-Thin-Walled Ceramic Tube
Thin-Walled Ceramic ComponentsOuter diameter Φ3.7 × inner diameter Φ3.49 × length 13.5 mm
This hollow, thin-walled zirconia ceramic tube is formed by isostatic pressing. The drawing specifies the inner and outer diameters, length, and cylindricity and coaxiality requirements for the inner and outer cylindrical surfaces. Edges must be smooth and free of burrs.

Manufacturing & MachiningEngineering & Quality
Consider design, inspection and joining together to understand key decisions in ceramic component development.
Engineering & Quality
Material Families
Alumina, zirconia, aluminum nitride, silicon nitride and silicon carbide offer different combinations of insulation, thermal conductivity, strength, toughness, wear resistance and corrosion resistance.
Our Services
Discuss a manufacturing approach around your ceramic material, machining and joining requirements.
Five Ceramic Material Families
Our scope covers alumina, zirconia, aluminum nitride, silicon nitride and silicon carbide. Start with a specified material or discuss selection for the intended use.
Forming, Sintering & Machining
Our services cover forming, sintering, grinding, drilling, lapping and polishing. The specific work is assessed against geometry, tolerances and surface requirements.
Joining & Mechanical Assembly
Our scope includes metallization, brazing, glass sealing and mechanical assembly, with the approach discussed around interfaces, service conditions and joint requirements.
