Compression springs - Import export

To ensure safe transport and enable an easy handover of the products during later industrial processes and assembly, we ship our springs and sub-assemblies in special packaging. Any conceivable special packaging is adapted precisely to the product in question, e.g. blister or polyethylene packaging. Tube packaging: Compression springs are transported in tube packaging. Tube packaging ensures that they can be inserted without problems, down to the last spring. Sub-assemblies, bent strip parts and laser-generated samples are transported in blister or polyethylene packaging to protect them during transport and storage. Modifying specific extraction mechanisms: We would also be pleased to assist you with our expertise regarding the modification of specific extraction mechanisms. This eliminates downtime of highly complex assembly equipment caused by springs getting caught up in one another.

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.

Volute Springs are used as compression springs and made from flat material coiled to a volute. The coils of the material overlap each other and are guided radially by each other during compression, thus giving the spring a stability against buckling that cannot be achieved with conventional compression springs.

Disc springs (also called Belleville springs) are geometrically a cylindrical washer with a slightly conical shape. It is used as compression spring and is the best solution when forces are high and travel relatively limited. This type of springs can or in parallel, which increases travel and/or force.

The mechanical back-up design uses SPIROL® Disc Springs. Under normal circumstances, the hydraulic system holds a constant pressure on Disc Springs stacked in series. If pressure fails to be maintained, the stack of Disc Springs decompresses to actuate the braking mechanism. A compression spring or wave spring is not capable of providing the force required (in the space available) to actuate the brakes. The reliability of this safety system is dependent on the consistent performance of Disc Springs. In this critical application, the Disc Spring’s performance and level of predictability improves product quality and ensures overall safety. SPIROL® Disc Springs have a high capacity to consistently store releasable mechanical energy. Visit www.SPRIOL.com to learn more!

Traction gas springs differ from conventional gas springs in that they operate in the pull direction rather than pushing out with force. In the unloaded state, the spring is compressed with the piston rod inside the cylinder.

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.

The COMPENSER® of the KL-series is an industrial shock absorber for light mechanical engineering, e.g. handling equipment, small storage and retrieval machines and small crane systems. Due to the low reset force of the compression spring, this buffer of the KL-series is well suited for operational push-in cycles at creep speed. Design & Function: The piston rod 2 pushes the piston 6 into the pressure chamber 7. At the same time, the damping medium flows through the metering grooves placed in the outer tube 8, via the piston 6 and into the volume balance chamber 5. The return spring 3 is tensioned and, after the impact has occurred, pushes the piston rod 2 back to the initial position. By this the damping medium flows back into the pressure chamber 7.

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.
