Marsh Mellow Die Springs by Firestone


The Marsh Mellow® Die Spring is a proven cost saver for the metal stamping industry. These springs can be used as a maintenance free replacement for costly self contained nitrogen gas cylinders. The unique construction elements are the secret of the spring's design flexibility. The spring's solid rubber core with hollow center and bias-ply fabric wrap are combined to meet special load and performance requirements. When designed into proper applications, these springs can give greater than 1 million cycles.
