1927 Charles Lindbergh flies nonstop from New York to Paris and Jules Stévenin takes up the challenge!
After his working day, he continues forging in his own shop and produces parts. The steel and coal is supplied by his boss who is now his customer!

Jules buys his first hammer during the thirties and his sons join the company… but for very little time as the war begins …

In the fifties, the family is back at work and the company specializes in a large variety of parts for overhead electrical lines as electrification of the country and Europe is booming : thousands of accessories are produced and millions of insulator pins are forged and galvanized ; Stevenin Nollevaux is a world leader and this speciality will remain until the nineties.

Anticipate and diversify are two key words for Stévenin Nollevaux! The electrical grids are completed so let’s look for new markets!

Nowadays the company delivers its components to many industry branches and export markets represent 80% of its turnover. Our customers are leading companies who have adapted to the high demand of the market as we do: the best technology in production lines, numerical simulation and robotization …

We would like to thank our customers, the Stévenin Family, and our employees who are contributing to the development of this dynamic, young company!

Explanation :

Just after forging, the forged nest (parts and flash) is put on the soleplate by the operator or the robot.

The press goes downwards :

The driving flank press holds the part.

The cutting tool presses the flash and the punching tool presses the part.

The cutting tool cuts the flash and the punching tool pierces the part; at the same time they press on the driving flank press and the stripper (both mounted and pressing on springs). The dampers move down with the stripper as they are attached to it.

At this stage the part has been trimmed and remains in the cutting tool; the flash remains around the soleplate.

The press goes upwards :

Above : thanks to the compressed springs the driving flank presses the part and gets it out of the cutting tool; the part remains on the soleplate.

Below : thanks to the compressed springs the stripper (braked by the dampers) moves upwards and ejects the flash out of the soleplate. The slow movement of the stripper avoids the flash being pressed against the part so the flash remains under the trimmed part.

The operator (different process for the robot) takes the part out of the flash.

BENDING is not as simple as you would think !

Bending is another technology that we can implement in our process for special products : after the part has been forged and is still hot we bend it in order to shape it to its final geometry.

The first step is to calculate and anticipate the material deformation thanks to our numerical simulation software and adapt the design of the forging. The steel grade and the temperature are very important factors but we also have to take into account further finishing operations such as heat treatment, cold coining, even machining.

The bending tooling is designed and manufactured in-house and then tested during the production of prototypes. Adjustments are usually necessary in order to reach the tolerances and functional dimensions, until we get a go ahead for production
