Product Specification

Precision Torsion Spring

High-Strength Steel Material | Consistent Performance | OEM & ODM Supported

Product Description

The Precision Torsion Spring is a mechanically engineered spring component designed to provide controlled rotational force and consistent torque output in a wide range of mechanical and electromechanical systems. By storing energy through angular deflection, torsion springs play a critical role in ensuring smooth motion control, reliable return force, and stable positioning of moving parts.

Manufactured from high-strength spring steel or stainless steel, precision torsion springs offer excellent mechanical strength, elastic stability, and resistance to fatigue. Advanced CNC coiling, precision forming, and controlled heat treatment processes are applied to achieve tight dimensional tolerances, uniform torque characteristics, and long service life, even under repeated load cycles.

Compared with standard springs, precision torsion springs are optimized for applications requiring accurate torque control, durability, and consistent performance. They are widely used in automotive systems, industrial equipment, electronic devices, tools, and automation mechanisms. To meet diverse design requirements, OEM and ODM services are available, allowing full customization of dimensions, torque values, materials, and surface treatments.

FAQ

Q1: Can you produce torsion springs according to customer drawings or samples?
Yes. We support OEM & ODM manufacturing based on drawings, samples, or detailed technical specifications.

Q2: What is the minimum order quantity (MOQ)?
MOQ depends on spring design and material. Small trial orders and samples are supported.

Q3: How do you ensure consistent quality?
Each torsion spring undergoes dimensional inspection, torque testing, and visual checks before shipment.

Q4: Are your torsion springs suitable for high-cycle applications?
Yes. Material selection and heat treatment can be optimized to meet high fatigue life requirements.

Q5: What is the typical lead time?
Sample lead time is usually 7–10 days. Mass production typically requires 15–25 days, depending on complexity.
