Associated Spring Raymond 103-512 Die Spring Blue Medium-duty

Product Description

The ASSOCIATED SPRING RAYMOND 103-512 is a medium-duty die spring designed for use in stamping dies, presses, and other tooling applications that require reliable, consistent compressive force. Built from chromium alloy steel with a trapezoidal wire shape, this spring delivers a spring rate of 171 pounds per inch and handles a maximum deflection load of 247.5 pounds at 1.5 inches of travel. The blue color coding follows the standard ISO die spring classification for medium-duty service. It is sized at 1 inch hole diameter and 0.5 inch rod diameter, making it straightforward to drop into existing die sets or tooling fixtures without modification.

This spring is suited for industrial tooling applications including metal stamping dies, injection mold components, punch and die assemblies, and general-purpose machine tooling where a compact, 3-inch free-length compression spring is required. The medium-duty rating positions it between light-duty and heavy-duty service, making it a versatile choice for moderate-cycle tooling where consistent return force is critical. Manufactured to ISO 9001:2008 and ISO/TS 16949:2009 standards with TUV Rheinland registration and ANAB accreditation, it meets the quality benchmarks expected in precision tooling environments.

Key Features

• Chromium alloy steel construction for durability under repeated compression cycles
• Trapezoidal wire shape provides higher load capacity relative to round-wire springs of the same size
• Blue color coding indicates medium-duty rating per ISO die spring standards
• 171 pounds per inch spring rate with a 247.5-pound maximum deflection load
• 1.5-inch maximum deflection at 3-inch free length
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an OEM-style replacement or direct-fit addition for tooling applications requiring a medium-duty die spring with a 1-inch hole diameter, 0.5-inch rod diameter, and 3-inch free length.

Installation Notes

Die springs are typically installed and serviced by toolmakers or die maintenance technicians. Before servicing any press or stamping die, de-energize the press and engage all mechanical safety blocks or die blocks to prevent inadvertent ram movement. Verify that the hole and rod diameters of the receiving pocket match the spring dimensions before installation. Springs should be replaced in sets when possible to maintain even load distribution across the die.
