Associated Spring Raymond 203-316 Die Spring 4 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-316 is a heavy-duty die spring designed for use in stamping dies, molds, and progressive tooling applications. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers consistent load performance and extended service life under repeated compression cycles. The spring has a free length of 4 inches (102 mm), a hole diameter of 16 mm, and a rod diameter of 8 mm. The green color designation indicates its load class within the ISO 10243 standard series. Licensed toolmakers, die setters, and precision machining professionals are the primary installers of this component.

This die spring is suited for use in metal stamping dies, injection molds, and other precision tooling assemblies where controlled spring force and repeatable deflection are required. It is appropriate for both light industrial and heavy production environments. With a maximum deflection of 41.80 mm and a spring rate of 44.54 N/mm, the 203-316 is well matched to applications requiring moderate, consistent return force in tight tool cavities. Specifications conform to ISO 10243 standards for die springs.

Key Features

• Trapezoidal wire cross-section for higher load capacity relative to round-wire springs of the same envelope
• Chromium alloy steel construction for fatigue resistance under high-cycle stamping conditions
• Green load-class designation per ISO 10243 for standardized identification and interchangeability
• Maximum deflection of 41.80 mm with a travel-to-solid load of 326.00 N
• Spring rate of 44.54 N/mm for predictable, linear force output
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as an ISO 10243 compliant die spring for use in standard die sets and tooling assemblies that specify a green-class spring with a 16 mm hole diameter, 8 mm rod diameter, and 4 inch free length.

Installation Notes

Die springs are installed by toolmakers or die setters during die assembly or maintenance. Always relieve all press tonnage and lock out the press before servicing any die components. Ensure the spring pocket or guide rod dimensions match the hole diameter and rod diameter specifications before installation. Do not compress the spring beyond its rated maximum deflection, as exceeding the travel-to-solid load will shorten service life and may damage tooling.
