Here’s a very handy reference document (courtesy of Hotwatt) for the application of electric heating elements in industrial and OEM applications such as extruding, vulcanizing, laminating, curing, bonding and thermoforming.

The heater application guide provides all the important technical look-up tables required to properly apply electric heaters, such as wattage calculation formulas and examples, properties of metals properties of non-metallic solids, properties of liquids and gases, suggested watt densities, estimates of wattage required, guide for heat losses, suggested sheath materials, installation,  Ohms Law, and typical wiring diagrams. The reference document is also very helpful when designing custom electric heating elements and designing a thermal system.
