There are some kinds of springs, like JIS die spring, US standard, Polyurerthane spring... Die spring with rectangular cross-section is the most frequent use in manufacturing or industry.
This kind of mould springs have a lot advantages: small volume, good elasticity, hard rigidity, high precision and etc. They are plated with different color to distinguish their load. Green, yellow, red and blue represent in order as extra-heavy, heavy, medium and light. The colorful appearance also has a good visual effect.
Deflection is the distance the spring compresses, expressed as a percentage of its length. As you squeeze a die spring, it gets harder to push. Rate is the amount of force required for every inch of compression. The higher the rate, the harder it is to compress the spring.
