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.
