In the automotive industry, coil springs are used in car suspension systems to ensure vehicle stability, shock absorption, and comfort. They are designed to withstand the repetitiveness of daily use and harsh driving conditions across every vehicle type from domestic cars to heavy-duty trucks, buses, and off-road vehicles. Other uses include seat mechanisms, clutch assemblies, brake systems, engine valves and vibration dampening to reduce noise inside the vehicle.

Machined springs are different. The flexure—the section providing the desired elasticity—is captive between the end sections, which provides structure and attachment. The end sections have infinite stiffness when compared to the flexure. Furthermore, the slots do not taper to zero at the ends; they remain at the full or initial width, as seen at free length. Thus, to achieve the same elastic performance, machined springs likely need to be longer than wire ones.

It’s important to understand the properties of the metal used to make your springs. Most coiling springs made for industrial or mechanical applications are chosen specifically for their corrosion resistance, ability to withstand high temperatures, and to maintain their strength even after repeated use. By choosing the right material for the right application, most coiling springs can provide very long, maintenance free service.

Stainless steel spring wire is a crucial element in various engineering applications, known for its unique properties that make it an ideal choice for springs and other components requiring durability and resilience. Composed primarily of iron, chromium, and nickel, stainless steel is recognized for its excellent corrosion resistance, strength, and ability to withstand high temperatures. These characteristics make it a preferred material in industries ranging from aerospace to healthcare, automotive to electronics.

Multiple start spring configurations unify the lateral bending and lateral translation forces and moments around a spring’s circumference given a lateral deflection. Configurations as high as five have been used to unify the lateral reaction of machined springs. Multiple Starts also add to the length of machined springs. Should a failure occur, the remaining coil(s) provide some functionality albeit degraded due to the missing coil.

Metal coil springs are made by winding a wire around a shaped former – a cylinder is used to form cylindrical coil springs.

Стиснуті пружини можуть мати різні форми та розміри в залежності від їх призначення. Найбільш поширеними є круглі пружини, але також існують квадратні та трикутні моделі. Кожен тип має свої переваги і недоліки, які важливо враховувати при виборі конкретної пружини для проекту.

A typical metal compression spring consists of a helical coil made from a robust metallic material, such as stainless steel, carbon steel, or music wire. The design of these springs can vary significantly, depending on their intended application, load requirements, and environmental considerations. The wire diameter, coil diameter, number of turns, and overall length can all be tailored to meet specific criteria.
