A torsion spring is a spring that works by twisting its end along its axis; That is, a flexible elastic object that stores mechanical energy when it is twisted.  When it is twisted, it exerts a torque in the opposite direction, proportional to the amount (angle) it is twisted.

Materials of torsion springs

Torsion springs can be manufactured from a variety of materials, common materials include Spring steel, carbon steel, stainless steel(301/316/17-7PH), piano wire, nickel alloys, copper alloys, and so on.

Compression springs are small and miniature in size.

Small compression springs can be made from wire diameters that range from .00275 to .015 inches in wire diameter.

Material of small compression springs

The materials commonly used for Small compression springs include music wire, stainless steel (types 302, 304, 316), spring brass, and phosphor bronze. The type of material used to manufacture small springs depends on the specific user requirements. Most medical devices are made out of stainless steel because stainless is corrosion-resistant and less magnetic than other spring steel. Phosphor bronze is commonly used in electrical applications since it conducts electricity.

Application of small compression springs:

Medical devices, auto-injectors systems, keyboards, push buttons, small pumps, or anywhere tiny springs are required.

Extension springs are helical wound coils that usually have hooks, loops, or end coils that are pulled out and formed from each end of the body. The function of an extension spring is to provide extended force when the spring is pulled apart from its original length. When there is no load, The coils of the tension spring are generally tight and there is no gap between the coils.

Extension springs are a type of mechanical spring that stores energy and generates a resisting force when stretched or extended. They are commonly used in various applications, including industrial equipment, automotive components, household items, and more. Extension springs work by exerting force in the opposite direction of their elongation when pulled apart.

Applications of extension springs

Doors and Gates: Extension springs are commonly used in garage doors, screen doors, and gates to counterbalance their weight and assist in opening and closing.

Automotive: They can be found in car trunks, hoods, and convertible tops to provide the necessary lifting force.

Industrial Equipment:  They are used in machinery and equipment to provide tension and absorb shocks or impacts.

Consumer Products: Items like retractable pens, toys, and adjustable lamps may use extension springs to achieve specific functions.

Agricultural Equipment: They are used in farm machinery and equipment for functions such as tensioning belts and cables.

Also known as battery contact springs or battery terminal springs, are components used in various electronic devices to establish electrical connections with batteries. These springs are designed to provide consistent pressure and maintain a secure connection between the battery and the device’s electrical contacts, ensuring proper power transmission.

Shape and Design of battery springs

They are typically coiled springs made from conductive materials like stainless steel or phosphor bronze. They are engineered in a way that allows them to compress and rebound, applying constant pressure on the battery terminals for a secure connection.

Compression and Resilience of battery springs

The springs are designed to compress when the battery is inserted into the device, creating a snug fit between the battery’s terminals and the device’s contact points. When the battery is removed, the spring expands back to its original shape.

Contact Points of battery springs

Battery springs have contact points at both ends—one end is attached to the device’s circuit, and the other end makes contact with the battery’s terminals.

Battery Types of battery springs

They can be found in devices that use a wide range of battery types, including cylindrical batteries (like AA, AAA, etc.) and coin cell batteries (like CR2032). The springs’ design may vary based on the specific type of battery they are meant to accommodate.

Applications of battery springs

Battery springs are used in a variety of electronic devices, such as remote controls, toys, flashlights, portable electronics, medical devices, and more. Any device that requires a replaceable battery is likely to incorporate battery springs.

Durability and Conductivity of battery springs

Battery springs need to be made from materials that offer good electrical conductivity to ensure efficient power transfer. At the same time, they should be durable enough to withstand repeated compressions and expansions without losing their springiness.
