More Metal Spring Manufacturers

Springs are essential mechanical components that store and release energy through elastic deformation. Their ability to change shape depends on the amount of force applied. However, excessive force can permanently deform a spring, causing it to lose its original shape and mechanical properties. Over time, springs may fail due to metal fatigue as continuous stretching and compressing introduce microcracks within the material, eventually leading to structural breakdown. Understanding spring fatigue, failure modes, and maintenance can help extend the lifespan of metal springs in critical applications.

Materials Used in Metal Springs

The composition of metal springs plays a pivotal role in determining their performance, lifespan, and suitability for specific environments. The choice of material is influenced by factors such as the application, the magnitude of stress or stretch the spring must endure, operating temperature ranges, corrosion resistance requirements, and the desired spring geometry. Selecting the appropriate spring material is a key decision for engineers and product designers seeking optimal reliability and longevity.

Most metal springs are manufactured using steel alloys, particularly high-carbon steel and oil-tempered low-carbon steel, due to their excellent strength, elasticity, and cost-effectiveness. However, for specialized industries and demanding environments, alternative spring materials are increasingly sought after. Common options include:

• Chrome silicon steel – Offers superior high-temperature performance and fatigue resistance, ideal for automotive and heavy-duty industrial springs.
• Chrome vanadium steel – Excellent for high-stress, high-shock applications such as suspension springs and aircraft landing gear.
• Stainless steel – Provides outstanding corrosion resistance, making it suitable for marine, medical, and food processing applications.
• Beryllium copper – Non-magnetic and corrosion-resistant, often used in electrical connectors and sensitive instrumentation.
• Phosphor bronze – Known for its resilience and electrical conductivity, commonly utilized in switches, relays, and electrical contacts.
• Titanium alloys – Lightweight, corrosion-resistant, and highly durable, chosen for aerospace, defense, and high-performance automotive components.
• Rubber or urethane – Used for non-coil and elastomeric springs where flexibility and noise reduction are priorities.
• Ceramic materials – Employed for coil springs operating in extreme high-temperature environments where metals may fail.
• Composite materials – Such as one-directional glass fiber composites, are under research for advanced spring manufacturing, offering unique combinations of strength, flexibility, and weight savings.

Manufacturing Process of Metal Springs

The manufacturing process of metal springs has evolved with advances in metallurgy and precision engineering. Understanding each step in the process is vital for ensuring spring quality, consistency, and performance. The typical steps in spring manufacturing include:

Contact us to discuss your requirements of belleville springs. Our experienced sales team can help you identify the options that best suit your needs.

1. Coiling

   The first step is wire coiling, which forms the basic shape of the spring. There are two main techniques:

   • Cold winding – Performed at room temperature, suitable for smaller diameter wires and high-precision springs.
   • Hot winding – Utilized for larger diameter wires, involving heating the material to increase ductility, followed by rapid cooling (quenching) in oil to set the coil shape.

   Automated CNC coiling machines ensure accuracy and repeatability for high-volume and custom spring production.

2. Hardening

   After coiling, the spring wire is stressed and must be tempered to restore elasticity and relieve internal stresses. This is achieved by heating the spring in an industrial oven at controlled temperatures for a specified duration, enhancing fatigue life and mechanical properties.

3. Finishing

   Finishing processes enhance the durability and surface quality of the spring. Common finishing techniques include:

   • Shot peening – Bombarding the surface with small steel balls to introduce compressive stresses, increasing resistance to metal fatigue and crack initiation.
   • Coating and plating – Applying protective finishes such as zinc, phosphate, or epoxy coatings to prevent corrosion and wear, especially in harsh or outdoor environments.
   • Grinding and polishing – Improving end flatness and surface smoothness for precise assembly and reduced friction.

Types of Metal Springs

Metal springs are engineered in a vast array of types and configurations, each designed to fulfill specific mechanical functions. The selection of the correct spring type is critical for achieving optimal force transmission, energy storage, or motion control in mechanical systems. Here are the most common types of metal springs and their typical uses:

Compression Springs

• A compression spring is an open-coiled helical spring that resists compressive forces and is designed to return to its original shape when the force is removed.
• Available in various shapes—cylindrical, conical, barrel, and hourglass—to suit space and force requirements.
• Widely used in automotive suspensions, industrial machinery, pens, valves, and medical devices.

Torsion Springs

• Torsion springs deliver torque by exerting a rotary force as they twist around an axis.
• Commonly used in hinges, counterbalances, clothespins, and automotive lift gates.
• Available in single or double configurations to accommodate clockwise or counterclockwise applications.

Extension Springs

• Extension springs are designed to store energy and resist stretching forces, returning to their original length when tension is released.
• Feature hooks, loops, or custom ends for attachment to other components.
• Common in garage doors, trampolines, farm equipment, and industrial machinery.

Constant Force Springs

• The constant force spring is a pre-stressed flat strip of metal that exerts a nearly uniform force throughout its extension.
• Ideal for applications requiring smooth, consistent force, such as cable retractors, counterbalances, and medical devices.
• When mounted on a spool, these springs provide constant torque for rotary applications.

Belleville Springs

• Also known as Belleville washers, these are disc-shaped, slightly conical springs that generate high force in a small space.
• Used for pre-tensioning, vibration damping, and thermal expansion compensation in bolted assemblies and machinery.
• Available in stainless steel, carbon steel, and specialty alloys for corrosion and temperature resistance.

Drawbar Springs

• Ideal for overload protection, drawbar springs feature a built-in safety mechanism to handle static and dynamic loads.
• Load is transferred through end-mounted steel bars to the spring center, providing compression under tension.
• Frequently found in agricultural implements, heavy machinery, and industrial safety equipment.

Volute Springs

• A volute spring is a cone-shaped compression spring capable of being compressed to a very short height.
• Used where space constraints require significant energy absorption in a compact form, such as garden tools and heavy equipment.
• The overlapping coil design allows for high load capacity in limited space.

Garter Springs

• A garter spring is a continuous coiled spring with ends joined to form a circle, providing radial tension.
• Commonly used in oil seals, shaft seals, and electrical connectors to maintain sealing pressure.
• Manufactured from carbon steel or stainless steel for durability and corrosion resistance.

Flat Springs

• Flat springs are precision-stamped metal components used for deflection, energy storage, and force control in tight or restricted spaces.
• Made from high-carbon steel, copper alloys, or titanium alloys, tailored to customer requirements.
• Key applications include electrical contacts, automotive switches, and precision instruments.

Air Springs

• Air springs are pneumatic devices—bellows or bladder-type—used for shock absorption, vibration isolation, and lifting.
• Employed in vehicle suspensions, industrial machinery, and material handling equipment to improve comfort and reduce wear.
• Also known as air cushions, these springs are valued for their adjustable stiffness and load-carrying capacity.

Custom and Specialty Springs

• Custom springs are engineered for unique applications, including precision medical devices, aerospace assemblies, electronic components, and other highly specialized systems.
• Manufacturers offer a range of design, prototyping, and testing services to meet the most stringent industry standards.
