Custom Compression Springs
Compression springs
arehelical coils
designed to resist compressive forces. When a load is applied, it shortens in length and stores potential energy.This energy is released when the load is removed, allowing the spring to return to its original shape.
At
ShengYi Intelligent Technology
, we cancustomize and process springs
of various types, sizes and materials. If you needstandard compression springs
, we are capable of delivering them in any quantity you require in a timely manner.-

Quality of
Compression springs
We provide compression springs and design services of the highest quality.
✓ Strong engineering design capabilities
Our engineers have many years of industry experience and have developed tens of thousands of products cumulatively. The team will provide you with services including design, drawing and mold development. It is worth mentioning that we often encounter products produced according to the drawings that do not meet the actual requirements and usage. It might be that the requirements for elasticity, fatigue resistance, hardness, etc. are not met. We will also provide you with the best solutions to ensure the smooth operation of your project and springs.
✓ Quality Assurance
Ensuring the quality of your materials is the most fundamental. We will also guarantee that the compressed springs produced by us can meet all your requirements, such as
load testing, fatigue life, environmental adaptability
, etc. And strictly follow the ISO9001 quality management system to carry out random inspections, patrols and other controls on the spring production process. Safeguard the quality of your products.
✓ Precision manufacturing
High-precision computer numerical control spring machines and automated feeding equipment reduce errors and mistakes in the production of compressed springs. In addition, the precision of the spring is guaranteed through precise detection equipment.

1
How to determine the lifespan of a compression spring?
The lifespan depends on the material, the design stress level (it is recommended to be ≤50% of the tensile strength), and the usage environment.
● Test method: Simulate the actual working conditions through a fatigue testing machine (such as 1 million cycle tests).
● Extended lifespan: Optimize end design (closed and ground smooth), surface treatment (such as shot peening). -
2
How to avoid permanent deformation (loosening) of springs during use?
●Material selection: Use high anti-relaxation materials (such as piano steel wire SWOSC-V).
●Heat treatment process: Low-temperature stress relief annealing (250-350℃) to eliminate residual stress in coiled springs.
●Load control: Ensure that the working stress is lower than the elastic limit of the material.
-
3
What are the special requirements for springs in the medical/electronic industry?
●Biocompatibility: The materials need to comply with the ISO 10993 standard (such as 316L stainless steel).
●Non-magnetic: Titanium alloy or non-magnetic stainless steel (such as SUS 631).
●Cleanliness: Electrolytic polishing or passivation treatment is carried out to prevent particle shedding.
-
4
What is the minimum order quantity (MOQ) for custom springs?
Generally, the MOQ is 1,000 to 5,000 pieces. However, for micro-springs (wire diameter <1.0mm) or special materials, we can support small-batch trial production (100 to 500 pieces), and provide rapid sample making services (3 to 7 working days).
-
5
How to determine if a spring needs surface treatment?
It depends on the application scenarios:
●Anti-rust: Galvanizing, nickel plating or electrophoretic paint.
●Conductivity: Gold-plated or silver-plated (suitable for electronic contacts).
●Abrasion resistance: Oxidation treatment (blackening) or solid lubricating coating.
