Associated Spring Raymond 204-108 Die Spring 2 in Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-108 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and tooling fixtures where consistent, repeatable force is required. This spring features a trapezoidal wire cross-section, which increases load-bearing surface area compared to round-wire designs and contributes to its rated spring rate of 50.82 N/mm. The blue color coding indicates its load rating category per ISO 10243 standards. With a free length of 2 inches (51 mm) and a maximum deflection of 19.40 mm, it is well suited for moderate-force tooling applications. Tool and die makers, machine builders, and maintenance technicians are the primary installers.

This die spring is designed for use in tool-and-die assemblies, mold bases, and industrial press tooling where space-constrained, high-cycle spring performance is required. It is guided by a rod with a 5 mm diameter and fits into a hole with a 10 mm diameter. Applications include stripper plates, blank holders, and component ejection systems in metal stamping and forming operations. Its chromium alloy steel construction supports high-cycle fatigue resistance in production environments.

Key Features

• Trapezoidal wire cross-section increases load capacity and fatigue life compared to round-wire springs
• Blue color code per ISO 10243 for quick visual identification of load class
• Free length of 2 inches (51 mm) with 19.40 mm maximum deflection travel
• Maximum deflection load of 172.70 N at full travel to solid
• Spring rate of 50.82 N/mm for consistent, predictable force output
• Manufactured to ISO 9001:2008 and ISO/TS 16949:2009 certified quality standards

Compatibility

Designed as a standard ISO 10243 die spring replacement for tooling fixtures, mold bases, and stamping die assemblies requiring a 10 mm hole diameter, 5 mm rod diameter, and 51 mm free length in the blue load category.

Installation Notes

Installation is typically performed by tool and die makers or maintenance technicians during die building or tooling repair. Ensure the mating hole and guide rod dimensions match the spring specifications before installation to prevent binding or premature failure. Relieve all press pressure and lock out the machine before servicing any tooling containing compressed die springs. Do not exceed the rated maximum deflection, as operating springs solid will accelerate fatigue and reduce service life.
