The manufacture of spirals of resistance wire is of the greatest importance for the correct function and long life of the heating elements. When coiling the resistance wire by hand , it is difficult to obtain a uniform pitch after cold stretching. Therefore, you often have to do hot stretch ,thereby eliminate the irregularities. However, hot stretching is much more expensive.
