DYNAMIC-CERAMIC
Wet Bag Isostatic PressingWet Bag Isostatic PressingCold Isostatic Pressing (CIP) is a method of compacting powders into green bodies and near net shapes in a pressure vessel. The powder is sealed in a flexible mold shaped like the end product. High pressure is used–30,000 psi). A high and uniform density is achieved, resulting in easier handling, easier machining and even and predictable shrinking during sintering.

SinteringSintering The machined
powder compact is fired or sintered in furnaces at temperatures up to 1800°C.
During the sintering process the powder compact shrinks ≈ 25%.

Precision MachiningPrecision Machining
• Once sintered the advanced ceramic component is extremely hard and can only be machined with diamond. Dimensional tolerances of less than 1/100 of the thickness of a human hair are possible

InspectionInspection
All common inspection techniques can be used
Difficult to detect defects within the component - good processing required
Crack detection performed on surface.
Remember Ceramics have “elephant like” memories
