Spring Back Tester

Determine the elasticity of your wire

The springback properties of your wire

A springback tester is used to measure how much a metal (or wire/sheet) elastically returns to its original shape after being bent, formed, or wound. Its purpose is to quantify this “springback” so manufacturers can adjust tooling and process parameters to achieve accurate final dimensions and consistent quality in formed parts. 

What springback is

When metal is bent or formed, part of the deformation is elastic and recovers once the load is removed, causing the angle or curvature to open up slightly; this effect is called springback. If not controlled, springback leads to dimensional errors, poor fit in assemblies, and more scrap or rework.

Role of a Spring Back Tester

A springback tester bends or winds a standardized specimen (sheet strip or wire) in a controlled way, then measures the residual angle or radius after unloading to obtain a springback value or “rounding behavior.” This measured value characterizes the forming behavior of the batch and helps define overbend angles, tool geometry, and process settings needed to hit target dimensions in production.

Where it is used

Springback testers are used in sheet metal and wire processing, such as stamping, bending, and can or tube production, where tight tolerances on bend angle or curvature are critical. They are particularly useful in plants that may not have full tensile-testing capability but still need a quick in‑plant check on formability and springback of incoming or in‑process material.
