Marni Spring is a manufacturer of high-precision, complex metal springs and wire forms. We’ve been in business for over 40 years. Our longevity is based on helping customers resolve spring problems via the most cost-optimal solutions.
Our custom springs and wire forms are made from high carbon steel, stainless, alloy steel, and copper alloys. Usually, cross-sections are round or square, with a multitude of diameters available. Complex, high tolerance parts (up to + .001”) are an everyday occurrence. Our production volumes range from a few prototypes to millions of units.
