Frequently Asked Questions
Q: How is coil weight calculated?
A: Coil weight is calculated using the formula: ((OD² - ID²) / 4) × π × Width × Material Density. This accounts for the annular cross-section of the coil multiplied by the width and the specific density of the material being used.
Q: What material densities does the calculator use?
A: The calculator uses industry-standard densities: Steel (0.283 lb/in³), Aluminum (0.100 lb/in³), Beryllium Copper (0.300 lb/in³), Brass (0.310 lb/in³), Titanium (0.163 lb/in³), and Stainless Steel (0.290 lb/in³).
Q: How is coil length determined?
A: Coil length is calculated using: ((OD² - ID²) / 4) × π / Thickness. This formula determines the total linear length of material wound on the coil based on the outer diameter, inner diameter, and material thickness.
Q: How accurate is the run time estimate?
A: The run time estimate assumes continuous operation at the specified strokes per minute (SPM). Actual run times may vary due to factors such as die changeovers, material feeding issues, quality inspections, and planned downtime. Use this calculation as a baseline for production planning.
Q: Why do I need to know the coil inner diameter?
A: The inner diameter (I.D.) represents the arbor or mandrel size around which the coil is wound. This measurement is essential for accurate weight and length calculations, as well as ensuring compatibility with your coil handling equipment.
Q: Can I use this calculator for metric measurements?
A: This calculator uses imperial units (inches and pounds). For metric conversions: 1 inch = 25.4 mm, and 1 pound = 0.4536 kg. We recommend converting your measurements to inches before using the calculator, then converting the results back to metric units.
