Product Specification

Custom Stainless Steel Torsion Spring for Wire Forming

Product Introduction

TOPONE custom stainless steel torsion springs are manufactured for applications requiring controlled rotational force, repeatable spring geometry, and stainless steel material performance.

The spring wire diameter range is 0.15–12 mm, allowing the specification to be matched to different torsion spring sizes and wire-forming requirements.

Torsion springs are designed to generate torque when their legs are rotated from the free position. The required wire diameter, material grade, coil diameter, number of turns, leg configuration, and working angle should therefore be considered together when selecting a spring.

TOPONE can manufacture customized stainless steel torsion springs according to customer drawings, dimensions, material requirements, and application conditions.

Product Parameters

Final material grade, mechanical properties, dimensional tolerance and spring specifications should be confirmed according to the customer's drawing and application.

Applications

Industrial Machinery

Custom torsion springs can be used in mechanical assemblies where controlled rotational force is required for returning, positioning, holding, or releasing components.

Automotive Components

Stainless steel torsion springs can be considered for selected automotive mechanisms where the required spring force, dimensions, material grade, and working environment are compatible with the application.

Household Appliances

Torsion springs can be used in appliance mechanisms requiring rotational movement or return force.

Hardware Components

Custom torsion springs are suitable for various hardware and mechanical components, including hinges, latches, clips, levers, and other wire-formed mechanisms.

Custom Wire-Formed Parts

The stainless steel spring wire can also be formed into customized spring components according to customer drawings and dimensional requirements.

Product Advantages

0.15–12 mm Wire Diameter Range

TOPONE stainless steel spring wire is available from 0.15 to 12 mm, covering fine-wire spring applications as well as larger industrial spring requirements.

The actual diameter should be selected according to the spring dimensions, required torque, working angle, available installation space, and forming process.

Multiple Stainless Steel Grades

Different stainless steel grades can be selected according to the required mechanical properties, corrosion exposure, forming conditions, and operating environment.

Common spring-wire grades include 302, 304 and 304H, while 316L and other grades can be considered for applications requiring different material characteristics. The final material should be confirmed against the actual service conditions.

Customized Spring Geometry

Torsion spring geometry can be specified according to the customer's technical requirements.

Important dimensions include:

• Wire diameter

• Inside diameter

• Outside diameter

• Number of coils

• Free angle

• Working angle

• Leg length

• Leg orientation

• Overall spring length

Bright or Soap-Coated Wire

TOPONE stainless steel spring wire can be supplied with a bright or soap-coated surface.

Surface selection should consider the spring forming process, tooling, lubrication requirements, and final application.

Drawing-Based Customization

For non-standard torsion springs, customers can provide drawings, samples, dimensions, or technical specifications for evaluation.

This is particularly useful when the spring must match an existing assembly or replacement component.

Torsion Spring Selection Guide

1. Confirm the Wire Diameter

Wire diameter is one of the primary parameters affecting torsion spring geometry and mechanical behavior.

TOPONE supplies stainless steel spring wire from 0.15–12 mm.

The correct diameter should be selected according to the required torque, spring dimensions, working angle, and available installation space.

2. Define the Spring Material

Material grade should be selected according to the working environment and required mechanical condition.

For example, 302 and 304 stainless steel can be considered for many general spring applications, while other grades may be evaluated according to corrosion exposure and application requirements.

3. Confirm the Coil Diameter

The inside or outside coil diameter should be specified according to the spring design and assembly space.

For torsion springs, coil diameter and wire diameter should be evaluated together rather than considered as independent parameters.

4. Define the Working Angle

The required working angle determines how far the spring is rotated during operation.

The free angle, working angle, and required torque should be provided when requesting a customized torsion spring.

5. Confirm the Leg Configuration

Leg length, leg direction, hook configuration, and mounting position should be defined according to the actual assembly.

A drawing or sample is recommended for complex torsion spring designs.

Technical Information Required for Customization

For an accurate torsion spring specification, buyers are recommended to provide:

• Stainless steel grade

• Wire diameter

• Inside diameter

• Outside diameter

• Number of coils

• Free angle

• Working angle

• Required torque

• Leg length

• Leg orientation

• Spring free length

• Surface requirement

• Applicable standard

• Quantity

• Packaging requirement

A technical drawing, existing spring sample, or dimensional specification can also be provided for customized production.

Manufacturing & Quality Information

For stainless steel spring production, quality should be evaluated using measurable technical specifications rather than general terms such as "good quality."

Important control points include wire diameter, material grade, spring dimensions, coil geometry, leg configuration, surface condition, mechanical properties, and applicable dimensional tolerances.

TOPONE supplies stainless steel spring wire and customized wire-forming products for industrial applications. Its published spring-wire range covers 0.15–12 mm, with bright and soap-coated surface options and multiple stainless steel grades.

For customized torsion springs, final specifications should be confirmed according to the customer's drawing, spring design, forming requirements, and operating conditions.
