A customer of ours had challenge with a product that required a recoil spring. They needed a custom spring that could handle excessive forces to be exerted on his product during use. Not only was it a load issue but the product was one that required repetitive and rapid compression and cycles. A single strand wire spring under these requirements would not hold up to such abuse. Century Spring Mfg sourced a special braided wire material that incorporated the additional life cycle and stresses required. We additionally built special tooling to form this material and design services to satisfy the customer’s needs for this very critical life safety application.
