Note: Brassiere Underwire
Objective:
To heat the ends of 0.072" spring wire, spaced 1/2" apart, uniformly for the application of nylon powder on a 1" length of the end. Once heated to 7000 °F, the nylon powder fuses to the wire creating a protective coating. Underwires have a past history of poking through the supportive garment and scratching the wearer. By adding a protective nylon coating at the ends of the wire form, this uncomfortable situation is avoided.
End Product:
Brassiere underwire
Equipment:
Ambrell 2.5 kW system including one remote heat station containing two capacitors with a total value of 0.66 µF
Unique five-turn elongated helical coil measuring 2 1/2" wide, 8 1/2" long, and 2 3/4" tall with the lower two turns angled down at the ends
Materials:
Spring Wire
Nylon Powder
Temperature:
700 °F
Frequency:
92 kHz
Testing:
700 °F was reached with a 12-second machine cycle. A uniform coating was produced as a result of even heating due to the unique five-turn elongated helical coil. 12 wire samples were heated simultaneously in the unique work coil.
