DieMax XL™ Light Duty Die Spring 40% Deflection Chrome Silicon (Inch)

This light-load die spring variant is used in injection mold tooling where a moving component must be supported with predictable compliance. In stripper plate and ejector return areas, the 40% deflection characteristic helps maintain consistent contact force while accommodating small dimensional changes and preventing chatter.

It also suits light-load forming and automation press tooling that interfaces with mold tooling, such as fixtures that feed parts or retract mechanisms. The chrome silicon design supports controlled deflection under vibration, improving repeatability during frequent cycling.

• Stripper/ejector return support: stable force with controlled compliance to reduce vibration and stick-slip effects.
• Light-load press and forming stations: damps shocks during intermittent contact without over-springing.
• Automation parts handling interfaces: helps protect sensitive components by absorbing dynamic loads.

DieMax XL™ light duty die springs are made from chrome silicon, a spring steel alloy selected for strong wear and fatigue performance under cyclic loading. Chrome silicon chemistry enhances hardenability and improves resistance to stress relaxation compared with simpler carbon spring grades.

For die spring applications, springs are typically supplied heat-treated for high hardness, then tempered to balance stiffness and toughness. This heat treatment approach targets high fatigue strength while maintaining sufficient toughness to avoid brittle failure during rapid deflection cycles.

• Hardness & trade-off: higher hardness improves wear resistance and fatigue life, while tempering is used to protect toughness.
• Wear resistance: chrome silicon improves durability under vibration and repeated impact-like loading.
• Material comparison: relative to basic carbon spring steels, chrome silicon generally offers better fatigue durability and more stable force over service life.

Select the spring dimensions to match your die spring pocket and guide clearances while achieving the intended deflection-to-force behavior for the load case. Use the provided ranges: Outer Diameter D = 1 ~ 5 in, Length L = 1 ~ 12 in, and Inner diameter d = 1 ~ 11 in.

• Check OD D: verify D fits the die spring station or housing bore without binding. Ensure adequate clearance for alignment through the stroke.
• Match free length L: choose L to achieve the design working deflection (40% deflection variant) within the available stack height and die open/close travel.
• Confirm ID d: ensure d accommodates the guide post or core feature diameter with the required radial clearance for motion and lubrication.

Tolerance/fit: because only nominal ranges are provided, confirm final fit with your die station tolerances (especially for D and d) to prevent side loading. These dimensions are configurable within the stated ranges; the 40% deflection characteristic is the fixed functional variant.
