ROI Calculation Logic

By introducing high-performance polyimide resin, assuming a 5% reduction in initial defect rates and a 20% extension in product lifespan for electronic components. For a company manufacturing 1 million units annually, this could reduce reproduction costs for defective products ($3.33/unit, AI est.) and warranty repair/replacement costs ($6.67/unit, AI est.). This translates to an estimated annual saving of ($1M units × 5% × $3.33/unit) + ($1M units × 20% × $6.67/unit) = ~$1.5M (AI est.).
