Graphic element Testing wire quality in steel coil spring manufacturing.
     
 
A new test identifies steel wire quality parameters influencing the fabrication of coil compression springs, allowing the elimination of 40 percent of bad wires prior to utilisation.
 

Coil springs are used in a very broad range of products, from pens, to prams, to playground equipment, to motor cars and in many industries using mechanical components, such as the electronics industry. One problem faced by every spring manufacturer is the lack of consistency in the physical properties of steel spring wire. Some wire simply does not behave in a regular and predictable way.

This project developed a new test for identifying steel wire quality parameters which have the greatest influence on the achievable dimensional tolerances in the fabrication of coil compression springs. Application of the test led to the elimination of 40 percent of bad wires prior to utilisation. The research involved considerable participation of SMEs Europe-wide.

Exploitation of the results and further research and development work have continued since the project ended and partners say they have considerably helped European spring coil and wire manufacturers to cut material waste, leading to lower energy requirements, the introduction of new standards observance and thus better quality products.
