Compression Spring Rapid Prototyping
Quick Spring can design and manufacture compression springs in a wide range of materials and size options, supplying from one piece to high volume as needed. Quick Spring specializes in rapid prototyping to assist in the design and manufacturing of rapid supply of compression springs.
Compression springs, also known as coil springs, are helical springs designed to resist compression along their winding axis. They are the most commonly used type of mechanical metal spring. These springs can operate independently or be assembled onto a guide rod or fitted inside a hole. When a load is applied to a compression spring, causing it to compress and shorten, it exerts an opposing force and strives to return to its original length. Compression springs are highly efficient energy storage devices that offer resistance to linear compressive forces.
The amount of energy stored in a compression spring depends on its material properties, wire diameter, and the number of coils. The spring's stiffness, referred to as its rate, is determined by the wire diameter and the number of coils. The spring rate represents the change in force per unit change in length and is measured in pounds per inch or newtons per millimeter. Adjusting the wire diameter or the number of coils allows for fine-tuning the spring rate.
Applications of Compression Springs
Compression springs find applications in a wide range of industries, from automotive, stamping presses, appliances to medical devices, cell phones, electronics, and sensitive instrumentation. Compression springs are essential in scenarios requiring a push-button mechanism. Conical compression springs are preferred in applications where a low solid height and increased resistance to surging are required. Conical springs have different diameters on each end of the spring.
Custom Compression Springs
Quick Spring offers comprehensive rapid custom compression spring manufacturing capabilities and engineering support throughout the design and production phases. Quick Spring can supply rapid prototypes custom compression springs which can be manufactured in various sizes and materials, including stainless steel, carbon steel, chrome silicon, and music wire.
Quick Spring's expertise, though focused on rapid, also encompasses advanced quality control systems, regulatory compliance (including RoHS, REACH, and DFARS), CAD-assisted product design, and a global supply chain network. The company is ISO 2015:9001 certified, REACH and RoHS compliant.
Quick Spring can produce custom compression springs in small or large quantities, catering to short-run R&D projects as well as larger orders in high quantity.

Design Considerations for Compression Springs
Types and Shapes of Compression Springs
Compression springs are available in various shapes, including conventional, conical, hourglass (convex), barrel (concave), and reduced end designs.
Key Parameters for Compression Springs
- Rate: Spring rate measures the change in load per unit deflection (in pounds per inch or Newtons per millimeter).
- Stress: The spring's dimensions, along with the load and deflection requirements, determine the stresses within the spring. Stress and stress range affect the spring's lifespan.
- Outside Diameter: This is the diameter of the cylindrical envelope formed by the outside surface of the coils.
- Hole Diameter: The hole diameter is the space where the compression spring is inserted. It should be larger than the spring's outside diameter to account for tolerance and spring expansion under load.
- Rod Diameter: This measurement pertains to the rod inside the compression spring, serving as a guide shaft to prevent spring buckling under load. The rod diameter should be smaller than the spring's inside diameter, factoring in tolerance.
- Free Length: The free length is the spring's length when it is not loaded, including anchor ends for extension springs.
- Wire Diameter: This is the size measurement of the raw material used to create the spring. Most compression springs use round wires specified by diameter.
- Solid Height: Solid height is the length of the compression spring when fully compressed, with all coils pressed together.
- Spring Set: Spring set is the permanent deformation that occurs when a spring is loaded beyond its material's elastic strength. It may be desirable or undesirable depending on the application.
- Load at Solid Height: This measures the force required to fully compress a compression spring until its coils are pressed together. It helps ensure that the spring can handle an assembly's maximum operating load, preventing it from bottoming out.
