Associated Spring Raymond 205-628 Die Spring 7 in Red

Product Description

The ASSOCIATED SPRING RAYMOND 205-628 is a heavy-duty die spring engineered for use in stamping dies, punch presses, and tooling fixtures. It carries a Strong duty rating and is manufactured from chromium alloy steel with a trapezoidal wire cross-section, which allows higher load capacity and longer fatigue life compared to round-wire alternatives. The spring measures 7 inches (178 millimeters) in free length and is color-coded red per ISO 10243 standards, making quick duty-rating identification easy on the shop floor. Tooling engineers, die maintenance technicians, and precision metalworking shops are the primary users of this part.

This die spring is suited for industrial press tooling applications requiring strong-duty force characteristics. It fits into tooling assemblies with a 32-millimeter hole diameter and accepts a 16-millimeter guide rod. The 53-millimeter maximum deflection allows for controlled, repeatable stroke travel under production cycling. It is appropriate for use in progressive dies, compound dies, stripper plates, and similar metalworking tooling setups where consistent spring force and cycle life are critical to part quality and tool longevity.

Key Features

• Strong duty rating per ISO 10243 for high-load tooling applications
• Trapezoidal wire shape delivers higher load density and extended fatigue life versus round wire
• Chromium alloy steel construction resists wear and deformation under repeated cycling
• Red color coding provides instant duty-rating identification per ISO 10243 standards
• Maximum deflection load of 800.68 pounds (3561.60 N) at full 53-millimeter travel
• Guide rod and hole diameter sizing simplifies drop-in replacement in standard die sets

Compatibility

Designed as an OEM-style replacement or new installation die spring for industrial tooling assemblies requiring a Strong duty, red-class spring with a 32-millimeter hole diameter, 16-millimeter rod diameter, and 7-inch free length per ISO 10243 specifications.

Installation Notes

Die springs are installed and serviced by toolroom technicians and die maintenance personnel. Always de-energize and lock out the press before accessing the die set. Ensure the guide rod diameter and pocket hole diameter match the spring specifications before installation to prevent buckling or misalignment under load. Springs should be inspected for set, cracking, or corrosion at scheduled tooling maintenance intervals and replaced as a set when possible to maintain balanced load distribution across the die.
