Associated Spring Raymond 203-512 Die Spring 3 in Green

Product Description

The ASSOCIATED SPRING RAYMOND 203-512 is a heavy-duty die spring designed for use in stamping dies, press tooling, and industrial machinery where consistent, repeatable force is required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a higher load capacity in a compact profile compared to round-wire alternatives. It carries a free length of 3 inches (76 mm), a rod diameter of 12.5 mm, and a hole diameter of 25 mm, making it a direct fit for standard die-set bores. Licensed HVAC and industrial technicians, tool-and-die makers, and maintenance professionals install this component in press and automation applications.

This die spring is suited for light-duty to medium-duty stamping and forming dies in both production and prototype tooling environments. It is color-coded green per ISO 10243 standards, indicating its load classification within the standard die spring color-coding system. The spring is used in applications where controlled deflection and repeatable spring rates are critical to maintaining part quality and die life. Maximum deflection is rated at 30 mm, making it appropriate for dies with moderate stroke requirements.

Key Features

• Trapezoidal wire cross-section increases load capacity and fatigue life compared to round-wire die springs
• Chromium alloy steel construction for high strength and resistance to fatigue under cyclic loading
• Green color coding per ISO 10243 for quick identification of load class in die-set assemblies
• 3 inches (76 mm) free length with 30 mm maximum deflection and a spring rate of 159.88 N/mm
• Hole diameter of 25 mm and rod diameter of 12.5 mm for compatibility with standard die-set hardware
• Manufactured under ISO 9001:2008, ISO/TS 16949:2009, and TUV Rheinland registration for quality assurance

Compatibility

Designed as an ISO 10243-compliant replacement die spring for standard die-set bores with a 25 mm hole diameter and 12.5 mm rod diameter in stamping, forming, and press tooling applications.

Installation Notes

Installation is typically performed by tool-and-die makers or industrial maintenance technicians. Always relieve all press pressure and lock out the press ram before removing or installing die springs. Inspect the bore and rod for wear, scoring, or misalignment before seating the new spring, as lateral loading accelerates fatigue. Do not exceed the rated maximum deflection of 30 mm during press operation.
