Wave spring is a firmness spring made of coiled flat wire using waves added along the coils to give it a spring effect. It is also known as coiled wave spring or scrowave spring. It occupies 30-50% of the compressed height space of equivalent round-wire springs with same deflection & load specifications. It is used in place of conventional round-wire springs in many motion-control applications such as gear assemblies, rotary unions, actuators, and different kinds of clutches and other customer applications. It offers space saving technology which can replace coil springs by less material and a smaller assembly size, resulting in construction being more cost effective. It is classified as compression, tension, and torsion. Compression springs operate under compression and tension spring operates in tension with a load attached. Additionally, torsion springs operate under twisting loads. It is used in different aerospace applications for instance fan blades, fuel systems, flaps, wheels, bearing preload, and throttle for shock absorption. It also used in drug delivery systems, dampers, and door operating systems.
The key benefits are included reduce spring height by 50%, fit tight radial & axial spaces, exotic alloys available, no tool charges on custom designs and same force and deflection as ordinary coil/ compression springs.
According to study, “World Wave Spring Market Research Report 2024(Covering USA, EU, China, South East Asia, Japan and etc)” the key companies operating in the world wave spring market are Smalley, Associated Spring, Borrelly, Baumann Springs, Scherdel, Rohit Springforms, Tru Wave, NHK Spring, European Springs & Pressings, Nippon Stainless Spring, Lee Spring, Ningbo Vulcan Mechanical Seals, Boker’s, Sunzo Spring, Tech Spring, Trisun ltd., Jiuguang, Micseal, Arbort, Wavespring, Tianshi.
Based on product type, wave spring market is segmented into crest-to-crest wave spring, single turn wave springs, circular-grain shim, nested wave springs, linear wave spring, springs-round wire wave springs and others. Linear wave spring acts as a load-bearing device with equal load-deflection properties as a wave spring. Based on materials, market is segmented into carbon steel, beryllium copper, elgiloy, stainless steel and Inconel. Based on shape type, market is segmented into round single turn, flat wave and others. Based on diameter type, market is segmented into custom (4 mm to 3000 mm and standard (5mm to 400 mm). Based on technology type, market is segmented into active coil and inactive coil. Based on weight type, market is segmented into light weight wave spring, medium weight wave spring and heavy weight wave spring. Based on heights, market is segmented into work height and free height. Work height of wave spring is compressed to for delivering the preferred force while free height of wave spring when uncompressed. Based on application, market is segmented into aerospace electrical connector, multi tooth cutter, vibration isolator, flow valve, clutch drive and others. In addition, based on end-user, market is segmented into aerospace industry, medical industry, automotive industry, oil & gas industry and others.
The wave spring market is driven by growth in demand for space saving technology, followed by increase in urbanization & rise in disposable income, increase in production of wave spring, rise in innovation from companies and increase in use of wave springs in various industries such as automotive industry. However, difficult to handle prestress in a high-speed turbine may impact the market.
Based on geography, China country holds major share in wave spring market owing to growth in automotive sector in the country. It is expected that the market will be reached at fast pace due to rise in investments in oil & gas industries over the forecast period.
