Gold Lamina Die Springs | Heavy Duty

Photo of Lamina DieMax gold die springGold Lamina die springs are made by Dayton Lamina and color coded white with gold (yellow) stripes to indicate that the springs have a heavy pressure rating. The brand name is DieMax.

The efficient Operating Range is 15% to 28% of the free length (L). Maximum deflection = 28%. Average life = 20%. Long life = 15%. Travel to solid is for reference only and not intended for operation. Deflection beyond the efficient Operating Range could create a safety hazard or and result in premature spring failure.

drawing of spring deflection parameters

The chart below provides the 28% deflection (F) and spring force in pounds for each heavy duty DieMax gold die spring. Also shown is the travel to solid deflection (S) and the spring force constant (K) for each spring.

Use the following equation to calculate the spring force in pounds for a given spring and deflection; Force = K x 10 x F, where K is the force constant and F is the deflection in inches.
