Compression Springs for Energy Absorption and Load Distribution in Mechanical Systems

In a wide range of mechanical systems, compression springs play a vital role in energy storage, shock absorption, and load distribution. These versatile components are critical in automotive suspensions, industrial machinery, valve assemblies, and consumer products.

At Dongguan Sango Hardware Fasteners Co., Ltd., we specialize in manufacturing high-quality compression springs tailored to your specific needs, from low-load applications to heavy-duty shock absorbers.

1. What Is a Compression Spring?

A Compression Spring is a mechanical component designed to compress under a load and return to its original shape once the load is removed. These springs provide resistance to compressive forces and are essential in absorbing impact, distributing pressure, and maintaining constant force in mechanical systems.

🔩 Key Benefits:

• Energy absorption during compression
• Consistent force distribution across surfaces
• Space-efficient design for load-bearing applications
• Durable and reliable over multiple compression cycles
• Available in custom sizes, material types, and spring rates

2. Types of Compression Springs

🔹 Cylindrical Compression Spring

• The most common type, with a simple cylindrical shape
• Used in automotive suspensions, piston assemblies, and push-button mechanisms

🔹 Conical Compression Spring

• Tapered shape that provides progressive resistance
• Ideal for shock absorption and variable load applications like automotive seats or heavily-loaded valves

🔹 Hourglass Compression Spring

• Tapered in both directions for space-saving and even load distribution
• Used in pressure control systems and valve assemblies

🔹 Torsion Compression Spring

• Designed to store rotational energy as it is twisted
• Common in door locks, mechanical timers, and latch systems

🔹 Biconical Compression Spring

• Combines the features of cylindrical and conical springs
• Used in high-strength applications requiring consistent force and uniform compression

3. Key Applications of Compression Springs

Compression springs are used across many industries requiring reliable force control, impact resistance, or movement management:

• 🚗 Automotive shock absorbers
• 🧳 Luggage wheels and retractable handles
• 🧪 Medical devices (pressure valves, oxygen regulators)
• 🧰 Industrial machines (pumps, conveyor systems)
• 🎮 Toys and game controllers
• 📦 Packaging machinery (pressure mechanisms)

They are essential in applications where constant pressure, resilience under shock, and force regulation are critical.

4. Material Selection & Specifications

Finish options:

• Passivated stainless steel for rust resistance
• Powder coating for color coding or anti-friction properties
• Electroplating (zinc, nickel) for added durability
• Black oxide or phosphate for corrosion resistance
