Compression spring (level spring) refers to springs that are compressed and store energy when pressure is applied to them, and when released, they open and release the stored energy. Most springs for use in devices are installed inside a hole or around a rod. In both cases, it must be ensured that the spring does not move and works in the desired direction. The compression spring is produced in different sizes in the spring industry. They have many uses in all kinds of devices. They are used in various industries such as industrial and agricultural machinery. Springs are also made with a very small and millimeter size, which are used in electronic devices such as mobile phones and scanners. Based on the type of application, compression springs can be classified into several categories as follows.

These springs are used when both radial or circular force is needed, and lateral (transverse) force is needed. A very simple example of the use of this type of spring is the use in a mouse trap. The spring placed in the trap causes; When the trap is opened, the radial and lateral force is stored, which is released when the force spring is released and the trap is quickly closed. These types of springs are also called small springs. Larger spring sizes are used in some automotive rods. Also, many small springs are used to make all kinds of projectors.

The shape of these springs is like a cone! That is, the diameter of the spring circles decreases on one side. The conical shape of these springs allows this; so that they can be used in limited spaces. Their tapered design creates a telescoping effect. That is, the force exerted by the spring for compression is not constant.
These springs are very popular in the automotive industry, especially in internal combustion engines, because their shape is stable, thus under repeated compression. , heavy and strong vibrations are stable and resistant. The stability of conical springs also allows them to perform well in small holes with low tolerance.

In this type of spring, like the conical spring, the diameter of the spring circles is not the same. But with the difference that in this type of spring, the two ends of the spring are narrow rings and the middle of the spring is wider, creating a shape similar to a barrel. These springs are made in two types, concave and convex. In the production of these springs, two conical springs are effectively combined and perform non-linear compression. Barrel springs have good stability in lateral pressure and work better than normal springs.

Compression springs are used in many cases, including: production, transfer and movement, evaluation of various parts, agricultural tools, etc. All components of large and small machine parts use compression springs in some way. The production of compression springs in spring manufacturing is almost more than other springs. Because these springs are among the most widely used. All people deal with it in their daily life. From the simplest devices such as pencils to cars and household appliances, these springs exist.
