As mechanical systems become smaller and more highly integrated, engineers often need to maintain required spring force while working within increasingly limited axial space. Conventional round-wire compression springs can consume valuable installation space and increase overall assembly size.

Lispring wave springs are manufactured from precision flat wire and engineered to provide controlled load and deflection within a significantly reduced axial envelope. Compared with conventional compression springs, wave springs can reduce spring height by up to 50% while maintaining equivalent force performance, helping engineers develop smaller, lighter, and more efficient assemblies.

Different configurations can be engineered around specific operating requirements. Single-turn designs suit applications with limited deflection, multi-turn wave springs provide smoother force characteristics and higher load capability, while nested configurations can support substantially higher loads in demanding equipment.

Material options include SUS301, SUS304, SUS316, Inconel X-750, Inconel 718, and Elgiloy, supporting applications ranging from general industrial equipment to corrosive, high-temperature, and high-strength operating environments.

Custom Design & Manufacturing

Lispring supports application-specific wave spring development, allowing engineers to define spring dimensions and performance around working load, installation height, deflection, life cycle, temperature, corrosion resistance, and assembly requirements.

Customization includes spring diameter, free height, operating height, number of waves, number of turns, material, load characteristics, and surface treatment. Engineering consultation and rapid prototyping further support design verification before production.

Engineering Value

For engineers, the primary value of a wave spring is not simply replacing a conventional compression spring - it is achieving the required spring force in less axial space. Lispring combines precision flat-wire spring manufacturing with custom engineering support to help designers optimize space, preload, load control, and service life for demanding mechanical assemblies.
