Direct answer
Establish a capable process with defined parameter windows before specifying machines. Automating an uncontrolled process industrialises the variability.
What this domain covers
- Quality varies with no identified parameter cause
- Recipes are held as tribal knowledge
- Scale-up from pilot underperforms
- Yield losses are accepted as normal
- Different lines produce different results with the same recipe
Solution approaches
Process characterisation
Identify critical parameters and their acceptable windows.
Capability studies
Cp/Cpk on critical-to-quality outputs before capital decisions.
Scale-up engineering
Translating pilot behaviour to production geometry and mass transfer.
Recipe and parameter management
Version-controlled recipes enforced by the control system.
Engineering and project considerations
- Raw material variability is a process input and must be characterised
- Parameter windows belong in the machine specification
- Yield improvement often outperforms capacity investment in cash terms
- Sampling and measurement must be capable before conclusions are drawn
- Documented process knowledge is an asset that survives staff turnover
What to prepare before engaging engineering companies
- Current parameter records and yield data
- Raw material specifications and observed variability
- Pilot or trial results
- Critical-to-quality output definitions
What to measure
Frequently asked questions
Can we automate an unstable process?
You can, but you will automate the instability. Stabilise first; automation then locks in the gain.
