The Resistance Wire coiling machine is used to wind the resistive wires into coils for tubular heaters.
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.
