Precision Wire Forming of Double Torsion Spring for the Safety Industry

(click on thumbnail to enlarge)

The complex double torsion spring shown here features multiple bends, angles, lengths and dimensions that is made complete off of one of our open-faced CNC wire formers. Our skilled operators incorporate the use of a special robot arm attachment that enhances our machinery's capability and allows our machine to handle the intricate bending required for this part. The use of positional probes allows the machine to check angle dimensions and will automatically shut the machine off if the probed angles are not attained which is a big aid in ensuring top notch quality.

This part displays Sterling Spring's dedication to technology and drive to keep our customer's costs as low as possible. By making this part complete off of the machine, we are greatly reducing lead times and are eliminating labor costs that come with the need for secondary operations. The cost savings is huge as we ship over 150,000 of these parts per year to our customer that specializes in the containment industry.
