Buy compression springs

Buy compression springs, you need to consider a number of factors to ensure that you can buy the right product. Here are some points and suggestions to look out for when we buy compression springs.

Pay attention when we buy compression springs

1.determine the needs

Application field: When I was about to buy compression springs, first clarify which industry or equipment the compression spring will be used for, because different applications have different requirements for the performance and material of the spring.
Working conditions: Understand the working environment the spring will face, including temperature, humidity, corrosion and other factors, which will affect the choice of materials.

2.choose the material

When I was about to buy compression springs, there are a variety of materials, common steel alloys (such as oil tempered low carbon steel, high carbon steel, stainless steel, chromium silicon, chromium vanadium, etc.), beryllium copper alloy, titanium and phosphor bronze. When selecting a material, it is necessary to consider its strength, corrosion resistance, elastic modulus and other properties.

3. Determine parameters

Shape and size: compression springs can be cylindrical, conical, convex, concave and other shapes. In addition, it is also necessary to determine the internal and external diameter of the spring, wire diameter, effective number of turns and other parameters.
Load and stroke: Specify the amount of load and deformation (i.e. stroke) that the spring needs to bear, which will affect the design and selection of the spring.

4. Consider other factors

Rotation: In some cases, it is necessary to put one spring inside the other spring, and the rotation of the two springs must be ensured. If you need to screw a bolt into the spring, you also need to make sure that the rotation of the bolt matches the rotation of the spring.
End type：The end type of the compression spring affects the pitch, compression height, total number of turns, effective number of turns and other parameters of the spring. The common end types are uncombined and unpolished, uncombined and unpolished, combined and tight state, and so on.
Perpendicularity and parallelism: These parameters affect how the axial force generated by the spring is transmitted to the parts connected to it. In some high-precision applications, the end face of the spring may need to be polished to improve perpendicularity and parallelism.

5. Purchase channels

Professional suppliers: Choose suppliers with good reputation and expertise who can provide compression spring products that meet standards and are customized according to customer needs.
E-commerce platform: Suppliers of compression springs can also be found on the e-commerce platform, but care needs to be taken to select reputable merchants and carefully check product parameters and performance requirements.

6. precautions

Safety: When using the compression spring, it is necessary to pay attention to its safety to avoid accidental injury.
Maintenance and replacement: Regularly check the performance and status of the compression spring, and timely replace the aging and damaged spring to ensure the normal operation of the equipment.
Price and Cost:In the premise of meeting the demand, consider the price factor. Compare the prices of different suppliers and choose the products with high cost performance. But please be careful not to pursue only low price and neglect product quality and performance.
Sample testing: Before large-scale buy compression springs, suppliers can be asked to provide samples for testing. Through the actual test to verify the performance of the spring to meet the requirements.
After-sales service: Understand the supplier’s after-sales service policy, including return policy, technical support, etc. This helps to solve problems that may be encountered during use.

In short, There are a number of factors to consider When I buy compression springs, including application fields, working conditions, material selection, parameter determination and so on. Through careful comparison and selection, you can ensure that the right compression spring products are selected.
