Associated Spring Raymond 204-916 Die Spring Medium Duty

Product Description

The ASSOCIATED SPRING RAYMOND 204-916 is a medium-duty die spring engineered for use in stamping dies, punch presses, and mold tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers reliable load performance under cyclic compression. It carries a maximum deflection load of 1,887.95 pounds (8,398 N) and a free length of approximately 4 inches (102 mm), with a maximum deflection of 38 mm. The blue color coding identifies the medium-duty rating at a glance, following ISO 10243 standards for die springs. Toolmakers, die setters, and mold technicians are the primary installers of this component.

This die spring is suited for medium-load die sets in metal stamping and plastic injection mold tooling. It fits into standard die spring pockets with a hole diameter of 63 mm and accepts a guide rod diameter of 38 mm. The travel to solid load is 38 mm, making it appropriate for applications where controlled deflection and repeatable spring force are required across high-cycle tooling operations in both production and job-shop environments.

Key Features

• Medium-duty rating with blue color code per ISO 10243 die spring standard
• Trapezoidal wire cross-section increases load capacity and fatigue life compared to round wire
• Maximum deflection load of 1,887.95 pounds (8,398 N)
• Free length of approximately 4 inches (102 mm) with 38 mm maximum deflection
• Chromium alloy steel construction for durability under cyclic compressive loads
• Fits 63 mm hole diameter with 38 mm rod diameter compatibility

Compatibility

Designed as an OEM-style replacement die spring for medium-duty stamping die sets and mold tooling applications requiring a 63 mm hole diameter, 38 mm rod diameter, and 102 mm free length per ISO 10243 specifications.

Installation Notes

Die springs of this type are installed by toolmakers or die setters with the press or mold completely de-energized and any stored mechanical energy relieved before service. Ensure the spring pocket and guide rod are free of burrs, debris, and excessive runout before installation. Do not exceed the rated maximum deflection to avoid coil bind and premature fatigue failure. Follow applicable shop safety procedures and press lockout/tagout protocols during all die maintenance work.
