Associated Spring Raymond 105-648 Die Spring Gold

Product Description

The ASSOCIATED SPRING RAYMOND 105-648 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and industrial tooling applications. It features a 1-1/4 inch hole diameter, a 5/8 inch rod diameter, and a 12 inch free length. The trapezoidal wire shape and chromium alloy steel construction deliver consistent force and extended fatigue life under high-cycle compression loads. Rated for a maximum deflection load of 748.8 pounds and a maximum deflection of 3.6 inches, the 105-648 is color-coded gold to indicate its load classification. A spring rate of 220 pounds per inch allows for predictable, repeatable performance across tool and die setups. This part is installed by toolmakers, die setters, and maintenance technicians in manufacturing environments.

The 105-648 is suited for compression applications in tool and die operations, injection mold assemblies, and mechanical press systems where controlled return force and dimensional consistency are critical. The gold color coding follows standard die spring classification conventions, identifying this spring within the extra-heavy load range. It is sold individually and is appropriate for both new tooling builds and replacement of worn springs in existing die sets.

Key Features

• Trapezoidal wire cross-section for higher load capacity and longer service life compared to round wire springs
• Chromium alloy steel construction for strength and resistance to fatigue under repeated compression
• Gold color coding identifies extra-heavy load classification at a glance
• 748.8 pounds maximum deflection load with a 3.6 inch maximum deflection
• Spring rate of 220 pounds per inch for predictable, linear force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or new-installation die spring for industrial stamping dies, punch press tooling, and mold assemblies requiring a 1-1/4 inch hole diameter and 5/8 inch rod diameter with a 12 inch free length in the extra-heavy load range.

Installation Notes

Die springs must be installed by qualified toolmakers or die maintenance personnel following all applicable machine guarding and lockout/tagout procedures before servicing any press or die assembly. Ensure the spring bore and rod diameter match the die set specifications before installation. Do not compress the spring beyond the rated maximum deflection of 3.6 inches, as over-compression will reduce fatigue life and may cause premature failure. Inspect mating components for wear or misalignment before installing a replacement spring.
