Why Choose A Machined Spring?

Design Engineers around the world have discovered the many benefits the HELI-CAL Machined Spring provides for their demanding applications. The versatile HELI-CAL Flexure can be incorporated into a single piece of material to be used in many spring load cases such as compression/extension, torsion, lateral bending, lateral translation, and more.

Solving Problems With Machined Springs

For more than 50 years Helical Products has been providing machined spring solutions to such industries as aerospace, aviation, medical tools and equipment, military, energy, as well as computer and semiconductor manufacturing. Solving the most difficult and demanding requirements has been possible because of Helical’s expertise in designing and manufacturing machined springs in specialty alloys including Inconel, titanium, stainless steel, and high-strength alloys MP35N, custom 455, and C300.

The ability to integrate multiple features into a machined spring is another benefit of the HELI-CAL Machined Spring. The integration of flanges, geometric shapes (squares, hexes, rounds, etc.), bearing seats, valve seats, gears, splines, bell-crank arms, internal and external threads, and other machinable shapes is available to the machine spring designer. The incorporation of these features into a single-piece solution reduces the number of parts needed in an assembly and simplifies installation. In the case of torsion springs, integrated attachment features enable the transmission of a pure moment which avoids many of the drawbacks of traditional wire wound springs. Helical’s team of Application Engineers is ready to assist in the design of a machined spring built to your specific requirements.

Because Helical’s springs are machined for a specific application and purpose, there are no stock machined springs. Applied to either high-precision applications or commercially graded needs, the versatile HELI-CAL Machined Spring provides superior elastic performance in many applications. Machined springs can be designed to specifically address requirements for rate, reactions at desired deflections, combined rates, modal properties, weight, inertial limits, and more. This application-specific approach facilitates an unusually good correspondence between what is desired and what is economically possible. Helical springs can also support such design objectives as reliability, repeatability, and multiple-part integration.
