Spring Manufacturer/How to Choose Compression Springs
Compression springs are widely used in automobiles, machinery, electronics, and everyday products. Choosing the right compression spring ensures product performance and durability. Below are the key factors to consider when selecting a compression spring:
1. Load and Force Requirements
Determine the maximum load the spring must withstand under working conditions.
Select an appropriate spring rate (spring constant) according to application needs.
2. Installation Space
Measure the solid height (maximum compressed length) and free length.
Ensure the spring will not be over-compressed or too loose within the available space.
3. Material Selection
Carbon steel wire (SWP): High tensile strength, prone to rust, requires surface treatment.
Stainless steel (SUS304): Corrosion-resistant, suitable for humid or special environments.
Silicon-chrome alloy steel / special materials: Suitable for high-temperature or high-strength applications.
4. Shape and Design
Cylindrical compression spring: Most common, provides uniform load distribution.
Conical compression spring: Prevents spring stacking, improves stability.
Barrel-shaped: Larger middle diameter with smaller ends, ideal for vibration absorption.
Hourglass-shaped: Smaller middle diameter with larger ends, enhances stability in specific applications.
