Have you ever considered using profiled wire as an alternative to round wire for spring production? If your product or application requires powerful springs to operate in confined spaces, you may want to consider switching to a flat, square, or rectangular option. Not only do profiled wire springs require less space to operate, but they also produce more force over a given distance compared to an equivalent round wire. What may seem like a small or insignificant change at first can actually provide revolutionary results.
Big Power in a Small Structure
Square and rectangular profiled wire produces more force over the same distance as traditional round wire, making them ideal for compression springs. If you compare a round wire spring to a square wire spring of the same size and material, the square wire will produce more force over the same distance. This is because it has more potential energy and energy storage. Simply put, they are able to store a tremendous amount of power in a relatively small structure.
Space Saving Solutions
Another advantage flat wire has over round wire is that it occupies less space when fully compressed. Like stacking boxes in a storage closet, flat containers are far more compact than round ones, and they sit side-by side without gapping. The same premise applies to spring wire. The flat edges of rectangular wire sit snuggly together with minimal space between the coils, reducing the overall space required to contain it. This can often allow manufacturers to substitute long round wire springs for shorter flat or rectangular ones without sacrificing power.
