What actually drives the 12-24 month range?

Shift patterns, output levels, and the extent of manual handling all influence how quickly an automation system pays for itself — a line running multiple shifts against heavy manual handling will typically see a return sooner than a lighter, single-shift operation.

Where does the value actually come from?

In many cases, the value comes from consistent operation and reduced reliance on manual labour over time, rather than a single dramatic cost saving — it compounds shift after shift.

How can I get a clearer estimate for my line?

A free trial or proof-of-concept on your own product is the most reliable way to see the throughput and labour numbers that would feed into your own ROI calculation.
