Technical metal springs

Metal springs are indispensable in numerous technical applications.
They are used to store, balance or transmit forces and are used in a variety of industries.

We are specialists in the various types of technical metal springs.
We have extensive and many years of experience in the properties, designs, special features, purposes and areas of application, design, calculation and manufacture of technical metal springs.

In particular, we specialize in torsion springs, double torsion springs, compression springs, tension springs, bent wire parts, stamped bent parts and special springs:


Thigh spring

Thigh springs:
Torsion springs, also known as torsion springs or torsion springs, consist of a wire that is spirally wound and has two legs. They are designed for the transmission of torque and rotational forces. The shape of the torsion springs can be different, for example simple helical springs or more complex windings such as conical or helical shapes. They are used in door closers, switches, tools and other applications where torsional movement is required. The calculation of the torsion springs includes parameters such as spring constant, winding geometry and material properties.


Double leg spring

Double torsion springs:
Double torsion springs are similar to torsion springs and consist of two specially combined torsion springs. In addition, double torsion springs have a central section that connects the two individual torsion springs. This section increases the load capacity and enables a higher spring force compared to conventional torsion springs. Double torsion springs are used in applications that require high spring forces, such as in valves, brakes or clutches. The design and calculation of these springs require careful consideration of stresses, deflection angles and contact areas.


compression spring

Compression springs:
Compression springs are helically wound springs that can take compressive loads. They are cylindrical or conical in shape and are used to apply resistance or force in a straight line. Compression spring designs can vary, from simple cylindrical spirals to conical shapes. They are used in a variety of applications such as B. in vehicle chassis, shock absorbers or spring clutches. The calculation of compression springs includes parameters such as spring constant, wire diameter, number of coils and material stiffness.


tension spring

Extension springs:
Tension springs are similar in design to compression springs, but are used under tensile loads. They consist of a wire wrapped around a central mandrel. In order to be able to initiate the power transmission into the tension spring, different eyelet shapes are used. Tension springs are used to generate or transmit forces along an axis. They are used in areas such as door mechanisms, window regulators or brake mechanisms. When designing tension springs, parameters such as wire diameter, spring constant, number of coils and spring length must be taken into account.


Bending part

Bending wire parts:
Wire bending parts are made from wire and have a complex geometric shape. They can be used in a wide variety of areas, such as electronics, medical technology or the automotive industry. The construction of bent wire parts requires a precise analysis of the geometric requirements and the required mechanical properties. These parts are manufactured by bending, cutting, punching or laser cutting.



Stamping and bending parts:
Stamped and bent parts are made from flat sheets or strips and have a complex geometric shape. They are used in various applications, such as electronics, the automotive industry or the manufacture of household appliances. The design of stamped and formed parts requires careful analysis of sheet metal thickness, bend radii, fasteners and other specific requirements. These parts are manufactured by stamping, bending, laser cutting or other suitable processes.

Special springs and special springs:
Custom springs include a variety of spring types that have been specially developed to meet individual requirements. They can have complex geometric shapes, special materials or unique construction features. Special springs are often used in specialized applications such as aerospace, defense and medical technology. The design, calculation and manufacture of such springs requires close cooperation between the engineers and the technical experts.

Technical metal springs play a central role in a wide range of technical applications.

Torsion springs, double torsion springs, compression springs, tension springs, bent wire parts, stamped bent parts and special springs offer different properties, designs and possible uses. Proper spring selection and design is critical to meet the specific needs of an application. Engineers must consider a number of factors when designing and calculating metal springs, including spring rate, material selection, body size, load distribution, and mounting requirements. With an in-depth knowledge of the different types of engineered metal springs, engineers can design the optimal solution for their specific applications, ensuring product performance, reliability and safety.

Technical metal springs
Technical metal springs are springs that are made of metallic materials and are used for technical purposes in technical applications. Technical metal springs are frequently used special or standardized machine elements that are used in many technical machines, devices, devices and everyday objects. Metal springs are made from special, very different metallic spring materials made of wire or strip material in different shapes and sizes.

Properties of technical metal springs
An essential property of technical metal springs is the elastic deformation when force or torque is applied. By using special elastic spring materials, the amount of elastic deformation can be greatly increased when force or moment is applied. In this case, the metal spring can store energy, as a result of which a restoring force, restoring moment, holding force, holding moment, closing force or closing moment acts.

Use and design of technical metal springs
The use and design of technical metal springs are very versatile and varied. Metal springs are used in numerous everyday products and household items such as office folders, paper punches, door handles, doors, keyboards, roller shutters, mixers, blenders, bicycles, cars, airplanes, ships, etc. The shapes, types and properties of metal springs are very different, as they are specially tailored to the function and application. Some designs have proven to be very useful and are used more frequently. The standardized metal springs include compression springs, tension springs, torsion springs, spiral springs, bent wire parts and shaped springs and many more.

Construction and calculation of technical metal springs
In order to determine the appropriate construction or design of a metal spring, the forces or moments, the path or angle of rotation and their direction should be determined or specified. If, for example, a longitudinal force acts with low lateral transverse forces (spring dampers in bicycles or cars) and this longitudinal force is to be supported or cushioned over a certain distance, a compression spring can be used. To determine the size and design of the metal spring, the forces, paths and the available space are required. The spring calculation program RS-Helix can be used to determine or calculate the size of metal springs.

Production of technical metal springs
Reiner Schmid Produktions GmbH has specialized in the manufacture of technical metal springs.
With us you will find technical springs in various designs and dimensions. For optimal application, we rely on the highest quality and versatile use. Technical springs that leave our house are perfectly tailored to the respective areas of application. They are robust, durable and meet the highest demands.
We take care of that right from the selection of materials, where we only decide on high-quality materials.
With us you will find torsion and torsion springs, as well as bent wire parts and double torsion springs.
We also offer you compression and tension springs and stamped and bent parts as technical springs.
Torsion springs make up a significant part of our range of technical springs.
Also known as torsion springs, these kinematic components take on the function of storing energy.
They also ensure the functionality of the individual components. On request, we can manufacture technical springs of this type for you as individual components. When it comes to ensuring optimum force distribution on both spring bodies in torsion springs, double torsion springs are the right choice. In addition to spring bronze, we also use brass wire and Inconel as materials. Other materials are nimonic, titanium wire and iron wire.

Stamped and bent parts are mainly used in the automotive and electrical industries. Due to the way they work, they can be used in many other areas. In order to be able to ensure that these are met, we offer stamped and bent parts that are manufactured with the greatest possible precision. You can rely on high quality features. With us you will find stamped and bent parts in material thicknesses from 0.2 to 1.2 mm and from 0.4 to 45 mm. Reiner Schmid Produktions- GmbH offers you technical springs for all areas of application. Like many other technical parts, technical springs are subject to constant further development. These developments pay off, because they have made it possible to manufacture technical springs that are even better tailored to our own areas of application.

Thigh springs
As early as the project planning phase, we calculate the necessary parameters for your torsion spring, such as force, kinematics, installation space and dynamic behavior, and carry out load change tests. This gives you the greatest possible product safety and quality. We reliably convert customer requirements into product solutions. We create drawings and samples or adapt the torsion spring to requirements. We manufacture torsion springs, torsion springs or torsion springs from high-quality spring steel wire at our location in Germany. The torsion springs are manufactured on CNC machines with different axes. In the cold forming process, we bring the spring steel wire into your desired shape. This results in mechanical energy accumulators for a wide variety of applications and industries. You will find our torsion springs for the transmission of torque in building services or in mechanical and plant engineering, many consumer goods as well as in the automotive and electrical industries. Simple examples of use are clothes pegs, safety pins, mouse traps with snap bars or bicycle luggage racks. Using the example of the safety pin, a torsion spring that has been wound once can be demonstrated well. The clothespin, on the other hand, is twisted or wrapped several times in the exact width.

Double torsion springs (double torsion and torsion springs)
We effectively use CNC machines with the latest control technology to manufacture your double torsion springs with great precision. Our production from stainless spring steel wire 1.4310 ensures good corrosion resistance. We produce metal springs with common standard spring steel, rust-resistant spring steel and other spring materials such as spring bronze, brass, titanium and much more. Double torsion springs, also known as double torsion or torsion springs, are made up of two spring bodies. They therefore have twice the torque and can be used in numerous technical applications. The two spring legs optimally distribute the forces to both spring bodies. Most of the time, the thighs are on the outside. Thanks to our modern production technology, we can also realize their position on the inside. Torsion springs are used in mechanical clocks, in moving-coil measuring instruments or for vehicle suspension; just to name a few of the areas of application.

Surface coating and tempering of metal springs
We can also competently and reliably handle powder coating, chemical or galvanic finishing, chrome plating or blackening of the surface. Alloying results in higher resistance and makes the spring steel wire more robust without increasing its radius. We also produce leg and double leg springs in the natural look of the spring wire as well as in polished, matted and colored variants.
