Designing with Ceramics
There are many aspects to consider when designing with ceramic materials. However, STC can manufacture to nearly any configuration or tolerance that can be manufactured in metal or other materials.
A FEW THINGS TO REMEMBER:
Any components that can be considered complete in the "as fired" state will be more cost effective. Most of the expense in manufacturing ceramic parts and components is in diamond grinding parts after firing. If your design can be made to net or near net shape in the "green state" (compressed powder, before firing) which can be machined with standard tooling, grinding costs can be reduced. Keep in mind that the industry standard tolerance for an "as fired" dimension is +/-1% or +/- .005", whichever is greater, as there is approximately 20% controlled shrinkage when firing ceramics. Also note that there is a .006" per inch camber allowance on as fired components and a .025" maximum radius or chamfer on all corners. Diamond grinding can easily produce tolerances of +/- .002". Tighter tolerances within tenths can be produced on a cost basis.
