Rectangular Wire Die Spring as per ISO 10243, Dia 16 Length 64, Red (R) Heavy Duty Load for precision dies and mould tools, designed for high load and controlled deflection.
Die Spring – ISO 10243 Standard
Model: 16 mm OD × 64 mm Free Length (Red – Heavy Duty, Code: R)
This heavy-duty die spring conforms to ISO 10243 dimensional and performance standards, designed for use in high-load die sets, press tools, jigs, and fixtures. The spring is constructed from high-tensile chromium-silicon alloy steel, precision cold-coiled and stress-relieved to ensure consistent elastic modulus and fatigue resistance under repeated compression cycles.
The rectangular wire section (thickness 2.5 mm) enables high energy absorption per unit deflection with reduced solid height. The spring exhibits a spring constant (k) = 3.1 kgf/mm, maintaining linear load–deflection characteristics across its operational range.
The maximum working deflection is 24.9 mm, with a maximum load capacity of 59.4 kgf ±10%. Beyond this range, permanent deformation may occur. The spring is identified by Red colour coding (R) indicating Heavy Load classification as per ISO 10243 colour standards.
Application:
Recommended for press tools, mould ejection systems, die sets, and high-frequency cyclic loading applications where consistent performance, dimensional accuracy, and longevity are critical.
