Calculating the True ROI of an Abrasive Flow Machining System

2026-06-22 17:46:20

Many extrusion manufacturers hesitate to invest in an Abrasive Flow Machining (AFM) system because of the higher initial cost compared to manual polishing. However, when you calculate the true return on investment (ROI), you’ll find that an AFM system pays for itself surprisingly quickly through multiple cost-saving channels.

The second major source of savings is extended die life. Manual polishing often removes too much material from the die surface, shortening its useful life. AFM uses flexible abrasive media that gently removes only microscopic imperfections, preserving the die’s original geometry and extending its life by 30-50%. For a facility that spends $500,000 annually on die replacements, this represents savings of $150,000-$250,000 per year.

Third, AFM significantly reduces scrap rates. Inconsistent manual polishing leads to die lines, surface defects, and uneven metal flow, resulting in scrap rates of 5-10% for many manufacturers. AFM delivers perfectly uniform polishing every time, reducing scrap rates to less than 2%. For a facility producing 1000 tons of aluminum per month at $2,500 per ton, this translates to savings of $750,000 per year.

When you add these savings together, the ROI calculation is clear. A typical AFM system costs between $80,000 and $150,000, but the annual savings can exceed $1 million. This means most facilities will achieve a full return on their investment within 12-18 months.
