Upload a DrawingTorsion springs are designed to generate torque when twisted around their axis. The stored energy is released through the spring legs, allowing the spring to control rotary movement, return components to their original position, or maintain a specific rotational force.
Torsion springs can be manufactured with different wire diameters, coil diameters, number of turns, leg lengths, winding directions, and end configurations. These options allow the spring to be customized for different torque requirements, installation spaces, and operating angles.
Our torsion springs are produced according to approved drawings, samples, or technical requirements. From material preparation and coiling to heat treatment, dimensional inspection, and packaging, each production stage is carefully controlled to support stable performance and reliable service life.
Torsion springs are widely used in molds, dies, machinery, automotive components, hinges, locks, electrical devices, and other mechanical assemblies. For a customized quotation, please provide your drawing, sample, torque requirement, working angle, installation dimensions, operating conditions, and expected quantity.

COMMON QUESTIONS
Answers Before You Ask
Clear answers to common purchasing questions.
Can you manufacture from my drawing without a standard part number?
Yes. Most of our projects start from a customer drawing or application sketch. We review the geometry, material and performance needs, then confirm manufacturability before quoting.
What is your minimum order quantity?
We support both small-batch prototypes and high-volume production. There is no fixed MOQ — quantities are evaluated based on the spring type, tooling and material requirements.
How do you handle springs for high-temperature or corrosive environments?
We select materials (such as Inconel, stainless steel or special alloys) and surface treatments matched to the operating environment. Our engineers can recommend options based on temperature range, media exposure and cycle life.
What documentation can you provide with production orders?
We supply inspection reports, material certificates, dimensional records and traceability documentation as agreed during project setup. PPAP and FAIR packages are available for automotive and aerospace programs.
What is the expected lead time?
Lead time depends on the spring type, material, tooling, quantity and approval requirements. We confirm the production and sample schedule during quotation.
How are payment and delivery terms confirmed?
Commercial terms, delivery address and documentation requirements are confirmed with the quotation before production starts.
What support is available after delivery?
After-delivery questions can be routed through the project contact for drawing questions, quality documents, repeat orders and application feedback.
Can you provide samples before mass production?
Yes. Prototype and pre-production samples can be arranged for dimensional, load and application approval before the full production order proceeds.
