Lever Springs, Torsion Springs, and Twist Springs: Manufacturing in Detail
Leg springs, torsion springs, and torsional springs are coiled spring elements that absorb torsional forces and generate a defined torque. When subjected to torsion, they are stressed rotationally by the twisting of the legs or the spring body. In assemblies, they perform functions such as locking or clamping and must be precisely matched to the available installation space and the required torque.
In practice, they serve as flap mounts, hinge springs, or release mechanisms. They are used wherever angular return and constant torque are required. Alfred Weigel manufactures these springs on a project-by-project basis for use in applications ranging from door handles to precision tools.
Our leg and torsion springs are characterized by:
- Simply Customized: Torsion and torsion-leaf springs manufactured to DIN 2194 specifications, tailored to customer requirements
- Simply reliable: Maximum process stability and dependable standards thanks to our ISO 9001 and ISO 14001 certifications
- Simply functional: Manufactured from a wide variety of materials, even for challenging environments, and featuring flexible manufacturing capabilities
- They are used in assemblies where a defined torque and reliable return are critical throughout the entire production run. This helps to permanently reduce assembly costs and the risk of customer complaints.

Weigel Spring Factory
Custom-Made Torsion and Coil Springs from Alfred Weigel
- Design based on drawings, samples, or functional requirements
- Adaptation to installation space, torque, winding direction, and mounting configuration
- Careful selection of materials based on environmental conditions
- A wide variety of surface finishes and treatments are possible
- Consistent quality from prototype production to mass production
A custom design of torsion springs and coil springs offers advantages in many applications, especially when:
- Operating conditions such as humidity, temperature, or vibrations influence the choice of material.
- A defined torque and reproducible return force are required throughout the entire production run.
- Several functions are to be combined into a single component.
Thanks to the project-specific design, requirements are taken into account early on, thereby avoiding design changes later in the project. This provides you with planning certainty for development, procurement, and series production.

Selected Applications in the Manufacture of Roll-Up Springs and Return Springs
Prototyping and Sample Production
For leaf springs, torsion springs, and torsional springs, it is crucial to verify the torque, leaf position, and function early on in the intended installation. Thanks to our in-house tooling department and our capability for specialized handcrafting, we can support this process flexibly and quickly. As a result, sample and prototype production can be an integral part of your project workflow.
- Based on your drawing, a sample, or technical specifications, we manufacture initial springs that can be tested in a real-world assembly or production environment. Feedback from assembly, testing, or endurance tests is directly incorporated into the optimization process before series production begins.
This structured approach reduces the need for adjustments during production, minimizes rework, and provides planning certainty for subsequent mass production. The transition from prototype to production parts is traceable and stable.
Additional Services Related to Torsion, Torsion Arm, and Torsion Springs
In addition to manufacturing individual leaf springs and torsion springs, we also support you with complementary services that simplify their use in mass production and reduce interfaces. Our goal is to provide a solution that is not only technically suitable but can also be efficiently integrated into your processes.
Combination of return springs with spring shafts, stamped and bent parts, or other functional components.
We can handle even small quantities or special requirements.
Packaging solutions tailored to logistics, assembly, or further processing.
For A-tier customers: Predictable supply, reduced effort in purchasing and warehousing.
All services are provided on a project-by-project basis and upon request. This ensures you receive exactly the scope of services that makes sense for your application.

Questions & Answers About Leg, Torsion, and Twist Springs
What is the difference between a leaf spring, a torsion spring, and a torsional spring?
Leg springs, torsion springs, and rotational springs all refer to the same type of spring: a coiled spring that absorbs torsional forces and generates a defined torque. The term “leg spring” emphasizes the free ends (legs) through which the force is applied. Alfred Weigel manufactures all variants to meet specific project requirements.
Do you offer sample or prototype production?
Yes. Samples and prototypes can be manufactured to test torque, leg position, and functionality under real-world conditions. Findings from these tests are directly incorporated into the production design.
Can torsion springs also be designed for mass production processes?
Yes. Alfred Weigel designs leaf springs and torsion springs to meet production specifications and tailors them to reproducible manufacturing processes to ensure a consistent torque curve throughout the entire production run.
What is the minimum quantity required for mass production?
Depending on the component and requirements, we can produce samples, small batches, and mass-produced items. The quantity is determined on a project-by-project basis and agreed upon jointly. We can produce prototypes upon request. Please note that our minimum order value is €250.
What materials can be used for torsion springs?
The choice of material depends on the operating conditions, load, and function. Common materials include cold-drawn spring steel wire and stainless steels for corrosive or humid environments, such as plumbing systems.
Can specific requirements for new industries be met?
Absolutely, since we always manufacture torsion springs and coil springs specifically for each project and exactly according to your drawings. For us, the possible applications are determined on a case-by-case basis by the function of your component rather than by fixed categories, so we develop the right geometric solution for every new application.
In which industries are leaf springs and torsion springs used?
We supply a wide range of industries, from the automotive industry to toolmaking and the plumbing sector. Our springs are used wherever precise torque and consistently stable performance are required in an assembly. Thanks to our ISO 9001 and ISO 14001 certifications, we guarantee reliable quality for every industry.
Can torsion springs be surface-treated?
Yes. Depending on the application, leaf springs and torsion springs can be treated with appropriate surface treatments to improve corrosion resistance, durability, or functional properties.
Is custom packaging also available?
Yes. Packaging solutions can be tailored to logistics, assembly, or further processing and are provided on a project-by-project basis upon request.
