Custom Stainless Steel Torsion Spring for Precise Wire Forming

Product Introduction

TOPONE custom stainless steel torsion springs are designed for mechanical assemblies that require controlled rotational force, return movement, or positioning.

The stainless steel spring wire is available in a diameter range of 0.15–12 mm and can be selected according to the required spring dimensions, material grade, mechanical condition, forming process, and application environment.

A torsion spring specification should be determined by considering wire diameter, coil diameter, number of coils, working angle, leg configuration, required torque, and installation space. These parameters work together to determine whether a spring is suitable for a specific mechanism.

TOPONE supports customized stainless steel spring and wire-forming requirements based on customer drawings, samples, dimensions, and technical specifications.

Product Parameters

Final material grade, dimensions, mechanical properties, tolerances, and spring specifications should be confirmed according to the customer's technical requirements.

Applications

Industrial Machinery

Stainless steel torsion springs can be used in mechanical assemblies where controlled rotational force or return movement is required.

Typical applications include positioning mechanisms, levers, latches, covers, clamps, and other moving components.

Automotive Components

Custom torsion springs can be considered for selected automotive mechanisms where the required spring geometry, material properties, and operating environment are compatible with stainless steel spring wire.

Household Appliances

Torsion springs are commonly used in appliance mechanisms requiring rotational movement, return force, or component positioning.

Hardware Components

The springs can be manufactured for hinges, clips, locks, latches, handles, and other hardware components according to the required dimensions.

Custom Wire-Formed Components

Stainless steel wire can be formed into customized spring components according to drawings or samples when a standard spring configuration does not meet the assembly requirements.

Product Advantages

0.15–12 mm Wire Diameter Range

TOPONE stainless steel spring wire is available from 0.15 to 12 mm, providing options for different torsion spring sizes and wire-forming requirements.

The final wire diameter should be selected according to the required torque, spring geometry, working angle, installation space, and forming process.

Multiple Stainless Steel Grades

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

Grades such as 302 and 304 can be considered for general stainless steel spring applications, while 316L and other grades may be evaluated for applications with different environmental or material requirements.

Customized Spring Geometry

The spring can be specified according to the customer's required geometry, including:

• Wire diameter

• Inside diameter

• Outside diameter

• Number of coils

• Free angle

• Working angle

• Leg length

• Leg direction

• Overall length

Flexible Surface Conditions

Bright and soap-coated surface conditions can be selected according to the spring-forming process, feeding equipment, and lubrication requirements.

Drawing-Based Production

For non-standard torsion springs, customers can provide a technical drawing, existing sample, dimensions, or application requirements.

This allows the spring geometry and material specification to be evaluated according to the actual assembly.

Torsion Spring Selection Guide

1. Confirm the Wire Diameter

Wire diameter is an important parameter affecting torsion spring geometry and mechanical behavior.

TOPONE stainless steel spring wire is available in the range of 0.15–12 mm.

The correct diameter should be determined together with the required torque, coil diameter, working angle, and installation space.

2. Define the Coil Diameter

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

For torsion springs, coil diameter and wire diameter should be evaluated together.

3. Confirm the Working Angle

The free angle and working angle should be defined according to the actual movement of the component.

The required torque should also be specified when requesting a customized torsion spring.

4. Define the Leg Configuration

Leg length, leg direction, hook design, and mounting position should match the actual mechanical assembly.

For complex spring designs, a drawing or existing spring sample is recommended.

5. Select the Stainless Steel Grade

Material grade should be selected according to the working environment, corrosion exposure, mechanical requirements, and forming conditions.

Technical Information Required for Customization

For customized stainless steel torsion springs, 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 direction

• Spring free length

• Surface requirement

• Applicable standard

• Quantity

• Packaging requirements

A technical drawing or physical sample can also be provided for customized production.

Manufacturing & Quality Information

For torsion spring production, measurable technical parameters should be used to define product requirements rather than general descriptions such as "good quality."

Important specifications include wire diameter, stainless steel grade, coil dimensions, number of coils, working angle, leg configuration, surface condition, mechanical properties, and dimensional tolerances.

TOPONE supplies stainless steel spring wire and customized wire-forming products for industrial applications. For customized torsion springs, the final specification should be confirmed according to the spring drawing, manufacturing process, and actual operating conditions.
