Evaluating springback (spread rate) of enameled wires | ENAMELED WIRE STIFFNESS TESTER (SPRING BACK METHOD) / No.163

• No.163-SB ENAMELED WIRE STIFFNESS TESTER (SPRINGBACK METHOD)
• No.163-HC ENAMELED WIRE STIFFNESS TESTER (SPRINGBACK ANGLE OF A HELICAL COIL)

Overview of ENAMELED WIRE STIFFNESS TESTER (SPRINGBACK METHOD)

Insert one end of the wire sample into the stopper hole on the mandrel and hang a weight on the other end.
Wind the sample around the mandrel three times at a rotational speed of 5–10 times per minute, mark the sample, and then remove the weight.
Slowly unwind the sample from the mandrel and read the scale at the position where the mark is located to evaluate its softness.

Overview of ENAMELED WIRE STIFFNESS TESTER (SPRINGBACK ANGLE OF A HELICAL COIL)

Insert one end of the wire sample into the stopper hole on the mandrel and hang a weight on the other end.
Wind the wire sample around the mandrel five times at the specified rotational speed, mark the sample, and then remove the weight.
Slowly unwind the sample from the mandrel and read the scale at the position where the mark stopped to evaluate its softness.
