Is a pre-furnace analyzer required?
Not every workshop needs analysis equipment right away, but all workshops need to know where they stand in the process.
Not every foundry needs analytical equipment from the start. A facility running a single melt, with low output and skilled workers maintaining stability, may not require it initially. However, as melt counts or production volume increase, experience-based methods become increasingly costly.
The following three questions help your factory determine the right time to invest, rather than deciding based on gut feeling or sales advice.
Key Control Points
Cast iron grade
Two or more changes per week make visual inspection insufficient.
Defect rate
If defects due to incorrect composition account for a significant portion of costs, analytical equipment is typically advantageous.
Depend on technicians
When only one or two people can read the log, turnover risk becomes production risk.
Customer Request
If the customer requires a lot-specific component profile, data is mandatory.
Real-world experience
- Start by recording the scrap rate and the number of batches requiring remelting for one month to establish a baseline.
- Prioritize the analyzer over the temperature sensor, as the latter is more cost-effective and requires less operational adjustment.
- Don't buy the most expensive equipment when you only need basic dual-core functionality.

Frequently Asked Questions
Should a very small workshop hire external analysis services?
Possible, but the wait time usually exceeds a single brew cycle, making it difficult to use for pouring decisions.
Can the analyzer replace a skilled technician's experience?
No. The device provides data, but adjustment decisions still require human expertise in the furnace and iron grade.
