Stainless Steel Square

This part displays our wide range of manufacturing flexibility through the forming of spring tempered, stainless flat stock material into this specialty power spring. We utilize custom tooling to control the flat material through a cam-less CNC open-faced wire forming machine programmed to bend and shape the part with tailored forming tools built by our experienced toolmakers. A strong setup, controlled working environment and the use of positional probes helps us ensure dimensional accuracy and hold tight tolerance requirements throughout the entirety of our production run.
A manufacturer of food preparation equipment contracted us to manufacture this square-centered power spring for one of their product lines. After helping our customer fine-tune their design through the prototyping stage, Sterling Spring manufactures over 140,000 of these power springs annually, delivered clean with no sharp edges, to this customer in Chicago.
