Coil Spring Manufacturers

What is a Coil Spring Suspension :

Coil Spring Suspension is a mechanical device with a helical coil formed from spring steel like an elastic materials. Because of its unique construction, the Coil Spring can compress, expand or spin when under load and then revert to its initial configuration when the load is released. Coil Spring have the ability to temporarily store load and release it when required, which makes them useful for controlling motion and force in mechanical systems. Each single ring is called as coil. The no. of coils of Coil Spring may be extended up to non functioning free height. Coil Spring is used for suspension system, absorbing load, jerk, shock, vibration etc. Coil Spring is treated as a safety component.

Coil Spring Suspension specification :

A Coil Spring Suspension is manufactured from round or rectangular flat bar or wire. It is forming by coiling in coiling machine in round ring shape maintaining the inside diameter continuously as per requirement up to required length. Each single ring is called as coil. The no. of coils of Coil Spring may be extended up to non functioning free height. Coil spring is manufactured in the form of gap between two coils is called Compression Spring and also other type in solid for without gap and forming pulling hook at both end called Tension Spring. Compression Coil Springs function for absorbing load, jerk, shock, vibration etc. Coil Spring Compression type is designed based on working space and spot and required load. Coil Spring compression type both ends are ground finished for proper fitment at working spot. The load measurement is based on the bar/wire diameter, inside diameter or outside diameter, no. of coils and free height or length. Coil Spring compression type function by applying pressure to gain actual performance while free height is reduced and tension type Coil Spring by installing one end hook fixed with device and pulling or hanging other end hook. At the time of function it extends the length up to capacity limit and absorbed load. When load or tension is released, the springs return back to previous position. Proper heat treatment is mandatory operational part of Coil Spring for fatigue life and perfect performance.

Coil Spring Suspension uses :

Coil Spring Suspension is used for various engineering items from Railway Bogie to Pen as per their application and demands. Here are some description against their application :

● Automobile Suspension :

Coil Springs are a crucial component in Automobile Suspension systems. It is providing a smoother ride by mitigating the impact of road irregularities. Coil Spring help maintain vehicle stability, support the weight of the vehicle and ensure proper alignment of wheels for improved handling and safety.

● Railway Bogie & Wagon :

In Railway Bogies, Coil Spring serve as primary suspension elements. They are used to support the weight of the Train and passengers while absorbing shocks and vibrations from the tracks. This ensures a smoother and safer ride, reducing wear and tear on both the Train and the tracks and enhancing passenger comfort.

● Machinery :

Coil Spring Suspension are widely used in various types of machinery for different purposes like :

# Crusher : In Crushers, Coil Springs are used to provide the necessary force for crushing operations and to absorb shock loads.
# Vibrator : Vibrator machine uses Coil Spring to support vibrating parts and to control motion, ensuring efficient and controlled vibrations.
# Screen : Coil Spring in screening equipment help maintain the tension and vibration needed to separate materials effectively.
# Valve : In Valves, Coil Spring ensure proper sealing and control of fluid flow by providing the necessary force to open and close the Valve.
# Actuator : Coil Spring in Actuator provides the force needed for movement.
# Vibration Isolator : Coil Spring used in Vibration Isolators to minimize the transmission of vibrations from machinery to surrounding structures.
# Elevator : In Elevators, Coil Spring act as buffers to absorb load and provide cushioning during the operation, enhancing safety and performance.

Coil Spring Suspension design :

There are various Coil Spring Suspension design are found as per their applicable and load bearing capacity. Here are some description how actually Coil Springs are designed :

● Closed ends :

Both ends of this design of Coil Spring is ground flat and parallel to each other. This type of design allows the Spring to stand upright and distribute the load evenly.

● Open ends :

Both ends of this design of Coil Spring is not modified; they remain in their natural helical shape.

● Pigtail ends :

Both ends of this design of Coil Spring is coiled down to a smaller diameter, resembling a pigtail. This design allows the Spring to fit into a socket or seat.

Coil Spring Suspension types :

Basically there are 3 different Coil Spring Suspension types are used as per their uses and application. Find the description bellow :

● Compression type :

This type of Coil Spring is designed to compress when a load is applied and return to its original shape when the load is removed.

● Extension type :

This type of Coil Springs are tightly coiled coils that produce tension when a load or force is applied to their ends, forcing them to lengthen. They are also referred to as Extension or Expansion Spring.

● Torsion type :

This type of Coil Spring is to operate with a twisting or rotational force. They store and release angular energy or apply torque.
