Sintering Shrinkage Allowance at 110% material correction factor: a worked example
What does the result look like when material correction factor reaches 110%? The full calculation is worked below with real intermediate numbers. a materials or design engineer needs to size a green blank so the fired ceramic component lands near the required dimension
The inputs for this scenario
- Green body dimension: 48 mm (unchanged)
- Linear shrinkage allowance: 0.18 mm/mm (unchanged)
- Material correction factor: 110 % (raised for this scenario; the documented default is 100)
- Fixed grinding stock allowance: 0.25 mm (unchanged)
Working through the calculation
- Applying the documented formula (Corrected shrinkage allowance = green dimension × linear shrinkage allowance × material correction factor) to the inputs above produces each figure below.
- At this operating point the engine returns 9.75 mm allowance for total sintering allowance, the number this scenario is built around.
- At this operating point the engine returns 0.2 mm/mm for linear shrinkage allowance.
- At this operating point the engine returns 9.5 mm allowance for corrected shrinkage allowance.
- At this operating point the engine returns 0.25 mm for fixed grinding stock allowance.
How this compares with the baseline
- Against the tool's baseline example, where material correction factor sits at 100% and the headline result is 8.89 mm allowance, this scenario comes in 9.72% above the baseline at 9.75 mm allowance.
- A figure at this level is achievable when material correction factor is genuinely sustained, not just peaked for a shift. It assumes uniform, isotropic linear shrinkage; real parts shrink anisotropically and shrinkage varies with green density gradients, so verify against fired sample measurements.
