Product Specification

Product Description

Compression springs are mechanical springs designed to resist compressive forces and return to their original length when the load is removed. They are widely used in mechanical assemblies to store energy, absorb shock, and maintain force between contacting surfaces.

Compression springs are commonly manufactured from high-quality materials such as stainless steel, carbon steel, music wire, or alloy steel. These materials provide excellent strength, elasticity, and fatigue resistance, ensuring long-term performance in demanding environments.

Various surface treatments such as zinc plating, nickel plating, powder coating, or passivation can be applied to improve corrosion resistance and durability. Compression springs are widely used in automotive components, industrial machinery, household appliances, electronic devices, and medical equipment.

Custom compression springs can be produced in different wire diameters, outer diameters, lengths, and spring rates according to customer drawings or specifications.

FAQ – Compression Spring

1. What is a compression spring?

A compression spring is a mechanical spring designed to resist compressive forces. It shortens when a load is applied and returns to its original length when the force is removed.

2. What materials are commonly used for compression springs?

Compression springs are typically made from stainless steel, carbon steel, music wire, or alloy steel depending on the application requirements.

3. Can compression springs be customized?

Yes, compression springs can be fully customized according to drawings or specifications, including wire diameter, outer diameter, free length, and spring rate.

4. What surface treatments are available for compression springs?

Common surface finishes include zinc plating, nickel plating, powder coating, passivation, and black oxide to improve corrosion resistance and durability.

5. What industries use compression springs?

Compression springs are widely used in automotive parts, industrial machinery, electronic devices, medical equipment, household appliances, and mechanical tools.

6. What is the typical wire diameter range for compression springs?

The wire diameter usually ranges from 0.1 mm to 10 mm, depending on the spring design and application.

7. How do you determine the correct compression spring size?

Key parameters include wire diameter, outer diameter, free length, number of coils, and required spring force. Engineers typically design springs based on these specifications.

8. What is spring rate in a compression spring?

Spring rate refers to the amount of force required to compress the spring by a certain distance, usually expressed in N/mm or lbs/in.

9. Can compression springs operate in high-temperature environments?

Yes, compression springs can be manufactured from heat-resistant materials such as stainless steel or special alloys for high-temperature applications.

10. Do you support OEM and ODM production?

Yes, manufacturers can produce custom compression springs based on customer drawings, samples, or technical requirements.
