At MAPES Wire Mill, three furnaces are used to heat treat copper and steel rods. In some cases temperatures exceeding 1900˚ Fahrenheit are required.
Once tempered the rods are transported to precision drawing machines where each rod may be drawn up to 30 times to achieve the prescribed dimensions and structural characteristics.
The process begins with 5/8″ steel and copper rods, of which the precise controlled chemical makeup is produced exclusively for MAPES.
Newly produced wire is tested for ductility, tensile strength uniformity and chemical composition. Computer systems test wire at a rate of up to 4,000 samples a minute, analyzing and comparing production line stock with company and client specifications.
