Flat-Form Springs & Coil Springs in Detail
Flat springs and coil springs are metallic spring elements made from strip material that are formed into their final geometry through stamping, bending, or coiling. In assemblies, they perform spring force, retaining, contact, or return functions and must be integrated precisely into the designated installation space. The focus is not on a single manufacturing step, but rather on the interplay of geometry, material, and function in their subsequent application.
In practice, flat springs and coil springs are frequently used as contact springs, friction springs, tension springs, retaining elements, or clamps. The requirements are determined by the assembly, electrical conductivity, load, and production process. That is why Alfred Weigel always manufactures flat springs and coil springs to be project-specific and easy to integrate.
Our flat springs and coil springs are:
- Simply and precisely punched, bent, or rolled from a wide variety of strip materials
- Simply Reliable: Maximum process reliability through ISO 9001 and ISO 14001 certification
- Easy integration: Designed for easy installation to ensure quick and seamless integration into your production process.
- They are used in assemblies where precise fit, defined spring force, and consistent quality are critical. This helps reduce assembly costs and the risk of customer complaints.
Standard vs. Custom Flat-Form Springs
Your Benefits at Alfred Weigel Federfabrik
Standard solution
- Predefined Geometries and Dimensions
- Limited flexibility in adapting to the available installation space
- Frequent compromises in spring force, service life, or electrical contact
- Limited selection of materials
- often compromises in installation and service life
Weigel Spring Factory
Custom Flat-Form Springs from Alfred Weigel
- Design based on drawings, samples, or functional requirements
- Adaptation to Installation Space, Load, and Installation Conditions
- Careful selection of materials to withstand environmental and media influences
- Reliable performance throughout its entire service life
- Consistent quality from small-scale prototype production to mass production
A custom design of flat springs and coil springs offers advantages in many applications, especially when:
- Several functions are to be combined into a single component.
- Operating conditions such as conductivity, temperature, or mechanical stress influence the choice of material
- Stable mass production with consistent quality is required.
Thanks to 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.
Manufacturing Characteristics of Our Flat-Form Springs
The Alfred Weigel Spring Factory manufactures high-quality flat springs for a wide range of industrial applications. We rely on a precise combination of custom geometries, first-class strip material, and well-thought-out manufacturing details.
Thanks to state-of-the-art manufacturing processes in accordance with DIN 6930 and DIN 6935, we provide customized solutions based on the required punching force and desired bend:
- Simply versatile: flat and coil springs made of spring steel or stainless steel, precision-manufactured as grinding or contact springs.
- Simply precise: The highest quality standards thanks to our ISO 9001 certification and comprehensive quality assurance
- Simply Customized: Thanks to our in-house tooling department, we can produce any geometry and any bending angle exactly according to your drawing.
- Simply conductive: High-quality surface finishes (gold-plated, nickel-plated, zinc-plated) for optimal contact applications.
- Easy to combine: Can be seamlessly integrated with other technical springs or components to form complex assemblies.
Selected Areas of Application
Prototyping and Sample Production
When developing new flat springs, it is crucial to test their geometry and function early on in their intended operating environment. Thanks to our in-house toolmaking capabilities and our ability to perform specialized handcrafting, we can support this process flexibly and quickly. Based on your drawings or technical specifications, we produce initial prototypes that can be tested in a real assembly environment under actual operating conditions.
- Based on your drawing, a sample, or technical specifications, we manufacture initial flat springs or coil springs that can be tested in a real-world assembly or production environment. Findings from assembly, testing, or internal trials are directly incorporated into the optimization of the component 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 Flat Springs and Coil Springs
In addition to manufacturing individual flat springs and coil 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. These services include, among others:

Questions and Answers About Flat Springs & Coil Springs
What is the difference between flat springs and coil springs?
Flat springs are spring elements stamped or bent from strip material, with either a straight or complex geometry. Coil springs are flat-wound strip springs that are primarily used as return elements or energy storage devices.
Do you offer sample or prototype production?
Yes. Samples and prototypes can be manufactured to test fit, spring force, and function under real-world conditions. Findings from these tests are incorporated into the production design.
Can flat-shaped springs also be designed for mass production processes?
Yes. Alfred Weigel designs flat-wound springs and coil springs to meet series production specifications and optimizes them for reproducible manufacturing processes to ensure consistent quality throughout the entire production run.
What materials can be used for flat-shaped springs?
The choice of material depends on the operating conditions, load, and function. Common materials include spring steel strip, stainless steels, and plated variants (nickel-plated, gold-plated) for electrical contact applications.
Can flat-shaped springs be surface-treated?
Yes. Depending on the application, flat springs and coil springs can be treated with appropriate surface treatments to improve corrosion resistance, electrical conductivity, or functional properties.
Is custom packaging also available?
Yes. Simply put: Packaging solutions can be tailored to logistics, assembly, or further processing and are provided on a project-by-project basis upon request.
What information is needed to submit a request?
