Customized machined springs are available in a variety of configurations and materials to accommodate those with precise spring requirements. The springs are curved beams machined from a single piece of material into the special configuration desired. The Heli-Cal Flexure, as the beam is called, can be made to incorporate special design features or characteristics. A specific advantage of this technology is that customer specified end attachments, such as tangs, clamps, flanges or threaded ends, can be integrated into single, multifunctional components. State-of-the-art CAD and finite element analysis software is used to create and optimize designs for specific applications.
