ISO14001:2015
As a precisionspring manufacturer
, we are committed to sustainable production. Our ISO 14001 certification ensures: minimizing waste and energy consumption in wire forming, heat treatment and coating. Strictly control the use of hazardous substances (RoHS/REACH) in springs for the medical and electronic industries.
Torsional Spring
The production process includes steps such as wire material inspection upon entry into the warehouse,
automated winding, heat treatment and surface treatment
. The production line is equipped with a real-time monitoring system that measures the wire diameter, free length, etc. in multiple ways to ensure that eachspring meets the design parameters
.After undergoing processes such as annealing and cleaning, the torsion spring is strictly inspected using calipers and laser measuring instruments to ensure that the final product's dimensions and torque indicators meet the design requirements.

1
How much mold cost is generally needed to make torsion springs?
Shengyi has the ability to independently develop and manufacture molds, so the cost of molds usually ranges from tens to hundreds of US dollars. And we also have universal accessories available for all customers to use.

2
How to extend the service life of torsion springs?
● Design optimization: Control the working stress to be ≤45% of the material's tensile strength.
● Surface treatment: Electrolytic polishing reduces stress concentration, or nitriding treatment enhances wear resistance.
● Load testing: The preloading cycle (" preset ") eliminates residual stress. -
3
What is the minimum order quantity (MOQ) for custom torsion springs?
● Standard torsion spring: MOQ 500-2000 pieces (depending on complexity).
● Micro/special materials (such as nickel-titanium memory alloys) : Support trial production of 100 to 500 pieces, and provide 3D drawing verification services. -
4
Can torsion springs be reused or recycled?
● Reuse: It is necessary to check whether the support arm is deformed and whether the torque has decreased (it is recommended to replace it regularly).
● Environmental protection and recycling: Stainless steel/titanium alloy can be 100% recycled, and material traceability certificates are provided (in compliance with ISO 14001). -
5
Which industries need high-precision torsion springs? What are the special requirements?
● Medical equipment: Corrosion resistance in sterile environments (such as titanium alloys), non-magnetization (MRI equipment).
● Consumer electronics: Miniaturization (wire diameter <0.5mm), quietness (such as the hinge spring of foldable screens).
● Automotive industry: High-temperature resistant (engine compartment spring), anti-vibration (door lock spring).
