Helical Compression Springs represent the most common spring configuration utilized in today’s marketplace. They are found in a wide variety of applications ranging from automotive engines and large stamping presses to major appliances and lawn mowers. They offer resistance to linear compressing forces, and are in fact one of the most efficient energy storage devices available.
Compression springs are typically manufactured from round wire and in a cylindrical shape. However square, rectangular, and other non- round cross section wire can be utilized, and springs can be shaped in barrel, conical, hourglass, or other profiles.
In this way, compression springs can be specifically tailored to applications that have, for instance, solid height restrictions or dynamic resonance conditions that need to be addressed.
Spacing between coils ( pitch ) can also be varied to provide different spring rates throughout the operating range of the spring.
Because of the number of compression spring characteristics that can be tailored to specific circumstances, this type of spring represents an extremely flexible design approach to force resistance and energy storage.
Different forms of COMPRESSION SPRINGS :
- COIL SPRINGS – CUSTOM MADE – BESPOKE SPRING DESIGN
- UPRATED SPRINGS – LOWERED SPRINGS
- SUSPENSION SPRINGS – AUTOMOBILE SPRINGS
- PROGRESSIVE RATE SPRINGS – RACE RALLY SPRINGS
- HIGH NICKEL ALLOY SPRINGS
The above sketches show the different end forms which can be specified for compression springs.
The hand of winding is sometimes important – for example in springs which work one inside another. See the images above which show how to identify the handing.
COMPRESSION SPRINGS – Custom made – bespoke spring design.
These are coil springs for actuator valves, electrical switchgear, ramp springs, horsebox springs, agricultural springs, relief pressure springs, pump springs and all engineering springs.
Custom designed from materials such as; Nimonic 90, Inconel 600, Inconel X750, Hastelloy C276, Titanium grade 2, Elgiloy, Monel and many more high nickel alloys as well as the more common Stainless steels such as type 302 and 316 and high carbon Chrome Vanadium or Silicon Chrome’
