Associated Spring Raymond 204-112 Die Spring 3 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-112 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. It features a trapezoidal wire shape that delivers a higher load capacity within a given space compared to round-wire springs of the same size. The spring has a free length of 3 inches (76 mm), a rod diameter of 5 mm, and a hole diameter of 10 mm. Rated at a spring rate of 30.26 N/mm with a maximum deflection load of 153.20 N, this unit is sized for light-to-medium load tooling cycles. Manufactured from chromium alloy steel and finished in blue per ISO 10243 color coding standards, it is a recognized replacement-grade component for die maintenance professionals and toolroom technicians.

This die spring is suited for use in metal stamping, forming, and blanking dies where consistent return force and repeatable deflection are required. The blue color designation under ISO 10243 indicates a light load classification, making it appropriate for applications where controlled, lower-force spring return is needed. It fits rod diameters of 5 mm and mounts in die sets with a 10 mm hole diameter. Toolroom machinists, die maintenance technicians, and press operators working in automotive, aerospace, and general manufacturing environments are the primary installers of this component.

Key Features

• Trapezoidal wire cross-section for higher load density versus round-wire equivalents
• Blue ISO 10243 color code indicating light load classification
• Free length of 3 inches (76 mm) with a maximum deflection of 28.90 mm
• Maximum deflection load of 153.20 N at full travel to solid
• Chromium alloy steel construction for durability in cyclic tooling environments
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an ISO 10243-compliant light-load die spring for use in standard die sets accepting a 10 mm hole diameter and a 5 mm guide rod.

Installation Notes

Installation is performed by toolroom machinists or die maintenance technicians during die assembly or scheduled spring replacement. Before servicing a press die, de-energize and lock out the press per applicable OSHA lockout/tagout procedures. Verify that the guide rod diameter and pocket hole diameter match the spring specifications before seating the spring. Do not exceed the rated maximum deflection of 28.90 mm, as compressing a die spring to solid contact accelerates fatigue failure.
