Frequently asked questions and after-sales answers

I. Product Performance

• Question 1: How is the elastic force of a compression spring determined?
  

• Answer: The elastic force of a compression spring is mainly determined by factors such as the wire diameter, number of turns, diameter of the spring, and the elastic modulus of the material. Generally speaking, the thicker the wire diameter, the more the number of turns, the smaller the diameter, and the greater the elastic modulus of the material, the greater the elastic force of the spring. We will determine the appropriate spring parameters through accurate calculation and testing according to your specific usage needs to meet the required elastic force requirements.

• Question 2: How long is the service life of a compression spring?
  

• Answer: The service life of a compression spring depends on multiple factors, including the usage environment, load size, working frequency, etc. Under normal usage conditions, if the load is within the design range of the spring and the usage environment is relatively stable, our compression springs can achieve tens of thousands or even hundreds of thousands of compression cycle lives. At the same time, we can also use special materials and processes according to your special needs to improve the service life of the spring.

• Question 3: How is the precision of a compression spring guaranteed?
  

• Answer: We use advanced production equipment and a strict quality control system to ensure the precision of compression springs. During the production process, the dimensions such as the wire diameter, number of turns, and diameter of the spring are accurately measured and controlled to ensure that each spring meets the design requirements. At the same time, we will also conduct sampling inspections to ensure the consistency and stability of the product.

II. Product Customization

• Question 1: Can special specifications of compression springs be customized?
  

• Answer: Certainly. We have a professional technical team and advanced production equipment and can customize various special specifications of compression springs according to your specific requirements. Whether you need a special wire diameter, number of turns, diameter, elastic force, or other special requirements, we can provide you with a satisfactory solution.
  

• Question 2: How long does it take to customize a compression spring?
  

• Answer: The time for customizing a compression spring depends on the complexity and quantity of the spring. Generally speaking, simple custom springs can be completed within a few days, while complex custom springs may take several weeks or even longer. After receiving your order, we will arrange production as soon as possible and communicate with you about the production progress in a timely manner to ensure on-time delivery of products.

• Question 3: How is the price of custom compression springs determined?
  

• Answer: The price of custom compression springs is mainly determined by factors such as material cost, processing cost, and quantity. We will conduct cost accounting according to your specific requirements and provide you with a reasonable quotation. At the same time, we will also consider factors of long-term cooperation and provide you with a more favorable price. Please contact us.

• Question 4: What needs to be provided for customization?
  

• Answer: Wire diameter, outer diameter, length, material, and number of turns are required. It would be better if you have a design drawing.

III. After-sales Service

• Question 1: What should I do if I haven't received the goods?

• Answer: You can take the initiative to contact the logistics transportation customer service first. If your problem still cannot be solved, please contact us and we will solve it for you and provide a solution.

• Question 2: What should I do if the size of the spring I received does not meet expectations?
  

• Answer: If you find that the size of the spring does not meet expectations after receiving it, please contact us immediately. Our technical team will conduct inspections and analyses. If it is caused by our production error, we will take responsibility and provide a new solution to ensure that the spring meets your requirements as soon as possible.

• Question 3: Why is the received 304 stainless steel spring material magnetic?
  

• Answer: The magnetic property of the received 304 stainless steel spring material may be caused by processing processes, chemical composition fluctuations, or environmental factors.

• Question 4: What is the reason for my 65MN spring rusting?
  

• Answer: 65Mn spring steel contains a certain amount of iron. Iron is prone to oxidation reactions when in contact with oxygen and water in the air. It is recommended to choose 304 stainless steel material.

• Question 5: What is the reason for my spring not rebounding?
  

• Answer: If the pressure on the spring exceeds its design bearing capacity, plastic deformation may occur, resulting in inability to rebound. You need to choose a larger spring.
