Associated Spring Raymond 105-448 Die Spring 12 in Gold

Product Description

The ASSOCIATED SPRING RAYMOND 105-448 is a heavy-duty die spring designed for tooling, stamping, and press applications where consistent return force and long cycle life are required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 288 pounds and a spring rate of 80 pounds per inch. The gold color coding identifies its load category per industry convention. With a 3/4-inch hole diameter, 3/8-inch rod diameter, and 12-inch free length, it is sized for mid-range tooling setups. Licensed toolmakers, die maintenance technicians, and industrial equipment specialists are the typical installers.

This die spring is suited for use in punch and die assemblies, injection molds, jigs and fixtures, and other precision tooling where controlled compression and reliable return stroke are critical. The 12-inch free length and 3.6-inch maximum deflection make it appropriate for applications requiring a longer travel range within standard die sets. It is a direct-fit replacement or upgrade in tooling designs specifying a 3/4-inch bore and 3/8-inch rod guide.

Key Features

• Trapezoidal wire profile provides higher load capacity relative to round-wire springs of equivalent size
• Maximum deflection load of 288 pounds with a linear spring rate of 80 pounds per inch
• Maximum deflection of 3.6 inches supports extended stroke applications
• Chromium alloy steel construction for fatigue resistance and dimensional stability under repeated cycling
• Gold color coding identifies load class for quick visual identification during tooling maintenance
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland quality system registrations

Compatibility

Designed as a standard-dimension die spring for tooling applications requiring a 3/4-inch hole diameter and 3/8-inch rod diameter with a 12-inch free length. No specific compatible model numbers or system families were identified in the available product data.

Installation Notes

Installation is performed by toolmakers or die maintenance technicians during die set assembly or spring replacement. Always de-energize and lock out the press before servicing the die set. Ensure the rod diameter and bore clearances match the spring specifications before installation to prevent binding or premature failure. Do not compress the spring beyond its rated maximum deflection of 3.6 inches.
