How to Use This Calculator
- Enter part weight (g) and material price per kg for your resin.
- Set cycle time (sec), press hourly machine rate ($), and number of cavities.
- Enter expected scrap rate (%) for your process.
- Review total cost per part broken down into material, machine, and mold amortization components.
- Use parts-per-hour output to validate production throughput against your order volume.
