Spring manufacturer - Import export

As part of a global design, manufacturing and technological development network which includes sites in Cornwall, UK, Lesjöfors in Sweden and Åminnefors in Finland, our manufacturing excellence and customer service is dedicated to world-leading products and services.

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

We have over 150 years spring manufacturing experience, and today produce the world’s largest range of coil springs for the automotive aftermarket. In addition to replacement coil springs, we also stock market leading ranges of Gas, Leaf and Sport springs.

Constant Force Springs are manufactured from flat strip material and spooled to a specific curvature matching the needed pull force. There is practically no limit on extension speed and acceleration. The springs can be fitted in a number of ways and extended partly or completely.

S-Ply® is the registered name for composite leaf springs that are manufactured by Prause Durotec. The reinforcing material has a strictly parallel-oriented, non-interlaced glass or carbon fibre structure. The fibres are neither pre-stretched nor bent. In contrast to metallic materials with an isotropic structure, they are direction dependent and therefore can be aligned to suit the material structure.   Epoxy resin compounds are used as binding agents. Their special balanced composition ensures high adhesion to the glass fibre surface, resulting in optimum dynamic and electrical properties. The ratio of matrix resin and reinforcement fibres has been chosen to profit from all of the benefits offered by the raw materials selected to form the composite material.   The matrix fulfils a number of important tasks. It provides fixing for the fibre in the desired arrangement and supports it against buckling when under compressive stress.  In addition, it has good load carrying and transmissio
