Since our founding in 1983, we have specialized in the design and manufacture of inductive components according to customer requirements, transformers, relays, and the manufacture of electromechanical assemblies.
For our products we maintain a well-equipped mechanical workshop, which is often underutilized. Our focus in the mechanical workshop is therefore on the production of small quantities of special turned and milled parts and their pre-assemblies.

We are currently 30 employees and our production area is approximately 2.500m².
Since 2002 we are certified according to DIN EN ISO 9001. Since 2018 in their current version 9001: 2015.

Supplier for technical springs and mechanical parts according to customer drawings.
Production and calculation of springs of all kinds
Largest standard spring camp in Switzerland.
Distribution of plastic standard parts.

Dutch Valley International has a network of 25 companies in India that can offer high precision turning and milling.
In addition, die-cast aluminum and the forming work.
We can also deliver sheet metal composite parts in high quality.
We also provide the surface treatment such as galvanizing, quenching, coating powder etc. etc.
We accompany quote request to delivery free domicile.

We edit and customize all Arte of feathers and feather products, and bending parts.

We are a small, in the area round, and flat grinding well qualified company in southern Germany. We specialize in the manufacture of precision components mainly made of tool steel and carbide. We also offer good skills in turning and milling.

We are fast, innovative, flexible - good in price and quality

The company FDB - wire bending and stamping parts was founded in 1995 in Allersberg.

In the years that have passed, we have been able to expand our company further. In 2003 a move to larger production halls became necessary.

We found this in Hilpoltstein, Industriestr. 18, where we still have our headquarters today.

We currently employ 40 people.
The company is run by the Bode and Frassa families.

Development, manufacture and sale of springs, wire parts, stamped and stamped bent parts as well
Assemblies and systems, bucket handles, bevelled rods and welded rings. Own construction and toolmaking.

"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.

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.
