How to properly use analysis equipment and technician expertise
Skilled workers can read the kiln, but no one can monitor twenty batches simultaneously; this data supplements experience rather than replacing it.
In many foundries, the decision to pour still rests with the master craftsman, who has two decades of experience. That experience is invaluable: judging color, flow, and pouring sound are all signals that equipment cannot measure.
The issue arises only when experience is the sole criterion. The device does not replace technicians; it converts perception into numbers for others to review later.
Key Control Points
Advantages of experience
Fast response, detects unexpected anomalies instantly—no waiting for results.
Experience limit
Cannot transfer between shifts, cannot save for reference, and relies on a single person.
Device Advantages
Ensure repeatable, storable, and comparable data across batches and months.
How to combine
Component verification device: Operator makes the decision. If results differ, recheck the sample before concluding.
Real-world experience
- When the technician and equipment disagree, always recheck the sample and cup first.
- Log instances where technicians detected anomalies that the system did not flag; this data is used to refine thresholds.
- Train new hires with data, not just observation.

Frequently Asked Questions
If you already have the device, can I skip the visual inspection step?
No. Visual inspection can detect abnormalities that instruments miss, such as unusual slag or abnormal flow patterns.
How to convince the foreman to use the equipment?
Show data to reduce the number of re-melts, and let the operator make the final decision based on that data.
