Flat springs

Heat treatment (Stabilisation)

The heat treatment allows to relax residual stress when the spring is being shaped. During this operation, the geometry of the spring can differ (diameter and lenght). The temperature and the exposition time can vary depending on the raw material used. We have go-through furnace at the machine outfeed and many other oven. All of them are equipped with a temperature recorder in order to follow and record the temperature needed on each application in actual time. They can be communicated on request.

Cleaning, tribofinishing, oiling

In many different activities cleanliness has become a major criteria. In order to answer to this demand we have an ultrasound machine that transfer the parts to a white room to obtain particles rate close to 300µ.

We are also equipped to reduce burrs following the grinding operation.

In addition, we have machines that can spray oil on steel parts who do not need surface treatment to guarantee a corrosion protection. We can get a finishing result as « dry when touched » or « lightly oily ».
