Spring wire - Import export

Cylindrical pullback springs are made with coils close to each other. At both ends of a spring, eyelets are bent up or screwed in. There are many factors which may have an influence on the shape of a spring and an eyelet. We advise and help you to find a suitable spring.

Bent wire parts represent a separate part of our production range. Bent parts differ from springs such as extension springs, compression springs and wave springs in terms of how they are produced. This type of spring is not only processed with automated machinery, but also involves a considerable amount of special handling, which we perform using our range of state-of-the-art equipment. Precision production with our high-tech machinery: Our range of machinery with an in-house toolmaking workshop enables three-dimensional bent parts to be produced with a wide variety of forms and with specialised finishes applied to the ends. Our range of machining processes includes: Bevelling, embossing, thread cutting, thread rolling, turning and milling. For bent wire parts, both CNC bending and mould-based bending are possible as production solutions.We process wire thicknesses of 0.20 to 8.00mm.Tool-based: 0.50 to 8.00 mm. Coating of part surfaces: Oiling, Vibratory finishing, Galvanisation.

We supply the European and international market with spring steel wire for temperable springs from our Iserlohn-Kalthof plant in sizes ranging from 7.0 mm to 40.0 mm

Spring isolators can be used for source and sender vibration isolation. The springs are manufactured of a special spring steel wire and KTL coated. Every spring isolator can be provided with an additional damping cushion of stainless-steel. Elemente with a frequency range between 3-4 Hz can be provided with a viscous damping, too. Spring isolators with a natural frequency range of 3-5 or 4-6 Hz are especially made for higher forces. They can be expanded in size and load-capacity without any difficulty. Spring isolators of RG+ are available for four different natural frequency ranges: Spring isolators with a natural frequency of 3-4 Hz Spring isolators with a natural frequency of 5-6 Hz Spring isolators with a natural frequency of 7-9 Hz Spring isolators with a natural frequency of 3-5 or 4-6 Hz

Generally, helical compression springs are made from circular spring-steel wires. The first and last windings are connected to the next one and usually ground with a diameter of 0.4 mm or more. Normally, the pitch (distance between the coils) and thus the spring characteristics are constant. In reality, special forms of compression springs are, according to space conditions and various needs, often required. Do not hesitate to ask us, we gladly optimize your applications with you.

Customised production to your specifications: We work very closely with you when it comes to producing torsion springs. Torsion springs are produced in accordance with your specifications based on drawings, prototypes or sketches. We manage the development process of the spring until it is ready for serial production. We produce torsion springs with wire diameters of 0.20 to 4.00 mm, with or without torque testing. Wire coatings: Galvanised, ZnAl-plated, Red-coated, Nickel-plated, Polished nickel, Phosphated, Brass-plated,Silver-plated.

Production to order – also with special-purpose materials as required: We only produce in accordance with customer specifications. Compression springs can assume a wide variety of designs and forms. Our production facilities include compression springs with wire thicknesses in the range of 0.30 to 3.00 mm with abraded ends and in the range of 0.10 to 4.00 mm with unabraded ends. Even extremely strict tolerances regarding length and strength are adhered to in our compression spring production facility. Special-purpose materials that meet specific requirements can also be integrated into production without any problems. Wire materials: All standard spring steel wires in accordance with EN 10270. Non-ferrous wires made of copper, brass and bronze. Special alloys such as: Hasteloy, CuNi44, NbZr1, TaW2. Other materials on request.

Multi-coil wave springs are made from flat-rolled spring wire that is coiled to a helical shape and the coils are at the same time given a sinus shaped wave form. The force-deflection relation is created by flattening out the wave form when the spring is compressed. The function is hence like a helically shaped leaf spring.

Wire forms can have a shape that is limited almost only by fantasy. Many of them have some kind of spring functionality, for example some quick fastening applications. In most products, the material is stressed in bending and they can be looked upon as leaf springs made from wire. Wire forms are manufactur

AViTEQ-Vibrating Circular motion screens divide into several bulk grain size ranges, seven small amounts of over-or undersize or separate from impurities and foreign matter from the screenings. Vibrating screens are working with directed vibrations/amplitudes, which are selected on special product to screen, depending on the installation conditions. The screens can separate different fractions simultaneously. The choice of the screen size and dimension depend on the task.
