Raymond® US Standard Inch Series Die Springs (Original Raymond® Trademark Colors, Proprietary Wire Shape) are offered in four robust duty ranges: medium, medium heavy, heavy, extra heavy.
Raymond® US Standard Inch Series Die Springs are ideal for sheet metal forming or other press tool applications that need a force applied or other applications that need to store and release energy. Die Springs can apply a higher force per inch of compression or deflection than traditional Compression Springs. Utilizing Raymond® Die Springs enables high lifecycles, longer durability, and longer time between maintenance.
