Manufacturing all types of springs for industry: compression spring, torsion spring, extension springs, flat springs, shaped springs

Since 1925, manufactures PIERON - a family in the 4th Generation - technical springs for virtually all industrial sectors. The focus in the automotive, electrical and sporting goods industry. At Bocholt the 189 employees realized on a plant area of 16,000 sqm always new solutions from the product areas rings, compression and torsion springs as well as punching, bending and wire bending parts. Special parts and assemblies complete our range of products successfully. State of the art manufacturing processes ensure all opportunities for a production that meets the highest requirements.

The spring Technology Group, headquartered in Kaltbrunn produced at 4 locations across Switzerland and has over 80 years of experience in the development and production of springs made of wire and tape, assemblies and mounting hardware. Portfolio: Compression Springs: In the range of dimensions, shapes and finishes. We process wires and rods of 0.2 mm to 20.0 mm in diameter as well as materials with rectangular or square cross-section up to 15 x 15 mm. For the following spring forms we have been established: cylindrical tapered (0.2 to 20.0 mm) biconical fitted barrel and chimney-shaped (0.2 to 3.0 mm) Our specialty: Progressive springs (0.2 to 3.0 mm) Extension Springs: In the range of dimensions, shapes and finishes. Oesenform according to customer requirements. We use different materials in the wire diameter range from 0.2 to about 10 mm; 10 mm to 16 mm without lugs, but with tabs or threaded inserts. Rotation and torsion springs: in the range of dimensions, shapes and finishes. The combination of turns, thighs and shapes are virtually no limits. We process materials round, square and flat wire diameter range from 0.2 to about 6 mm. Larger wire diameter on request. Bent wire parts: We have an excellent infrastructure for the production of wire bending parts in a variety of shapes and finishes for medium and large series. We process materials in the diameter range from 0.2 mm to about 6 mm. Flat springs: leaf springs are metal mold parts which possess elastic properties, to clamp, hold or rest. The great diversity requires an enormous mobility and overview. We use different materials in thickness from 0.1 mm to 4 mm, width up to 300 mm (cold or hot worked). Other dimensions on request. Processing in hard condition or processing in soft condition with subsequent tempering.We manufacture flat spiral springs and disc springs. Stampings: We develop and manufacture for you Stampings according to your wishes and requirements. We advise you from the design to the mature part series. Our modern prototype workshop provides you with a short first sampling. The necessary tools are manufactured in our own workshop and our new punching and bending machines manufacture your parts at high speeds with maximum precision. Material thickness: Thickness 0.1 mm to 3 mm, Width up to 160 mm.

"WE ARE WORKING ON THE ACHIEVEMENTS" Grueber springs, this name stands in the rail industry worldwide-conformal and repeatable quality steel springs. With 180 employees, produces Grueber per year, approximately 9000 tons of steel springs and bent parts, and achieves a turnover in 2012 of about 34 million euros. A quarter of the production is for the rail industry. Well-known international manufacturers of railway equipment put on the quality of Grueber springs. Thus, at the booth this year to see springs for the • double-decker Stadler - DOSTO, • the Italian high speed train Frecciarossa 1000 (Bombardier / AnsaldoBreda) • the Siemens trains Lastotschka for the Olympic Winter Games in Sochi, • coaches of Indian Rail, • and the tilting ICEs of Alstom, which are set in a DB. Of special requirements for the space over low-temperature resistance to extreme corrosion protection requirements solutions are presented that Grueber has worked with its customers. A brand new development in the field of web application are heavy springs from inconstant wire. This construction enables a progressive course of the spring characteristic. In operation, the trains at low loading are soft suspension, whereas with increasing loading the suspension is harder. The resulting pressure force of a spring differs depending on the position of the spring ends from getting on the geometric center line. Under load, the springs have a tendency to shift vertically. Accurate measurements of the transverse deflection and paired set of springs with the same behavior ensure in the primary spring stage uniform load distribution in the bogie for optimum quality and high safety against derailment and ensure in the secondary suspension stage for a symmetric status of development on the bogie to comply with the allowable light room. Move rotary motion of the bogie in curves and traveling through switches the secondary spring is forced into an S-shape.Nevertheless, the spring coils should not touch and do not lift the spring ends. Extensive testing methods ensure at Grueber for the safe operation of the component spring in practical operation.

We are specialised in springs, wire parts, and metal assemblies.

On our precision and quality you can set. We offer a broad, comprehensive portfolio of technical feathers. Thanks to our flexible manufacturing capabilities, we are able to produce your individual components. Whether it is flat spring components or complex three-dimensional curved shapes of wire and strip steel - we produce the optimal solution for your claim. No matter whether you need a one off, a small, medium or large series, Search or advice in the preparation of prototypes. Make our many years of experience to your direct benefit!
