Associated Spring Raymond 203-412 Die Spring 3 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-412 is a heavy-duty die spring engineered for use in stamping dies, press tooling, and industrial mold assemblies. Built from chromium alloy steel with a trapezoidal wire profile, it delivers consistent load characteristics and long service life under high-cycle conditions. The spring has a free length of 3 inches (76 mm), a hole diameter of 20 mm, and a rod diameter of 10 mm. Maximum deflection is 30 mm with a spring rate of 91.36 N/mm. The green color coding indicates its load class, allowing for fast identification during setup and tooling changes. This part is installed by toolmakers, die setters, and industrial maintenance technicians.

This die spring is suited for use in metal stamping dies, injection mold assemblies, and general industrial press tooling where repeatable spring force and precise travel-to-solid performance are required. The 203-412 fits applications calling for a 20 mm hole diameter and 10 mm rod diameter. With a travel-to-solid load of 480 N at 30 mm of deflection, it is appropriate for medium-load tooling applications in both production and maintenance contexts.

Key Features

• Chromium alloy steel construction for high-cycle durability in press and die applications
• Trapezoidal wire cross-section provides higher load capacity per unit length compared to round wire
• Green color coding identifies load class for quick visual selection during tooling setup
• Free length of 3 inches (76 mm) with 30 mm maximum deflection
• Maximum deflection load of 480 N at full 30 mm travel to solid
• Manufactured to ISO 10243 standards with ANAB accreditation and ISO 9001:2008 certification

Compatibility

Designed as an OEM-style replacement or standard fitment die spring for industrial stamping dies, mold bases, and press tooling requiring a 20 mm hole diameter and 10 mm rod diameter with a 3-inch free length in the green load class per ISO 10243.

Installation Notes

Die springs are installed and replaced by toolmakers, die setters, or qualified industrial maintenance technicians. Always de-energize and fully de-stroke the press or mold before removing or installing springs. Verify hole diameter and rod diameter clearances match the 203-412 specifications before installation. Do not compress the spring beyond its rated maximum deflection of 30 mm to avoid permanent set or premature fatigue failure.
