Working With You for Custom Designs
Our experienced staff at Alumina Ceramic Components, Inc. has the skills to work with you from the initial design stage through to project completion. During those initial design stages, alumina shrinks approximately 20% during firing. This means more complex designs have difficulty holding tolerance stability.
Parts with more simple designs can be produced more uniformly. Green-pressed density and sizes can be controlled better, and a more uniform green density means that tighter tolerances can be held.
Avoid Unnecessarily Tight Design Tolerances
Tighter tolerances cost more during manufacturing. Geometric tolerances may look nice on the drawing, but if they are not necessary, they will cost more during manufacturing as well as during inspection.
Even though it is easier to hold tighter tolerances on small parts, small I.D.s can cause excessive tool breakage.
- Wall thickness should be kept to approximately 10% of O.D. or a minimum of .020 when possible.
- This includes the distance between the holes, as well as the distance from the I.D. to the O.D.
- Depth of blind holes should not be greater than 50% of the overall length.
Simplicity Is the Key to a Good Design
There should be as few steps or levels as possible in your new design. Multiple levels cause areas of compaction that may result in changes in green press density. These changes in density may cause the fired part to be porous, resulting in shrinkage differences that can affect the dimensional stability.
