Associated Spring Raymond 204-106 Die Spring Blue

Product Description

The ASSOCIATED SPRING RAYMOND 204-106 is a blue-coded die spring engineered for use in metal stamping dies, molds, and industrial tooling applications. It features a trapezoidal wire cross-section that delivers higher load capacity in a compact envelope compared to round-wire springs of the same size. With a free length of 1.5 inches (38 mm), a rod diameter of 5 mm, and a hole diameter of 10 mm, this spring fits standard die sets requiring a light-to-medium load profile. The blue color coding indicates its deflection load range per ISO 10243 standards, making spring selection and replacement straightforward on the shop floor.

This die spring is suited for use in punch and die assemblies, injection molds, progressive dies, and similar tooling found in metal fabrication and plastics processing environments. It is typically installed and serviced by tool and die makers, mold technicians, and maintenance machinists. The 204-106 is designed for repetitive cycling under controlled deflection, making it appropriate for both new tooling builds and replacement applications where a worn or fatigued spring must be swapped out during scheduled die maintenance.

Key Features

• Blue color code per ISO 10243 for quick load-class identification during tooling setup
• Trapezoidal wire shape provides higher load density compared to round-wire die springs of equivalent dimensions
• Free length of 1.5 inches (38 mm) with a maximum deflection of 14.4 mm
• Maximum deflection load of 171.40 N at full rated travel
• Spring rate of 67.95 N/mm for predictable, consistent force output
• Chromium alloy steel construction for durability under high-cycle fatigue conditions

Compatibility

Designed as an OEM-style replacement or new-build component for standard die sets and tooling assemblies requiring a 10 mm hole diameter and 5 mm rod diameter die spring with a 1.5 inch free length.

Installation Notes

Die springs of this type are installed by tool and die makers or toolroom machinists during die assembly or maintenance. Always relieve all press or clamp pressure and verify the tooling is fully de-energized before removing or installing springs. Ensure the rod diameter and hole diameter clearances match the tooling specification before installation. Never compress a die spring beyond its rated maximum deflection, as overtravel will accelerate fatigue failure and may cause spring fracture.
