The Wheelabrator Allevard group has grown up around two major activities:
-
Steel abrasive, a field in which Wheelabrator Allevard has invested since 1960 and is today a world leader.
-
Diamond tools, a sector in which Wheelabrator Allevard has been active since 1990 and has gained around 5% of what is still a highly fragmented market.
Impact Treatment
What do abrasives do?
There are numerous applications of shot and grit :
• in foundries, for the desanding and cleaning of pieces,
• in the steel industry for the descaling of metal sheets, billets, profiles...
• in metal construction, for the preparation of surfaces before painting or metallisation.
• in shot peening, where shot strengthens the subject pieces (springs or gear-boxes) considerably as they are subjected to an intense fatigue, and gives a good cost/performance ratio !
 What are the advantages of abrasives?
Abrasives have made great advances in surface treatment:
Cleanliness - Environment
Shot blasting is a mechanical process carried out in an enclosed place so it does not generate any risk of environmental pollution. The abrasive is used many times as it is recycled.
Simplicity and mastery of the process
It works in a simple way and is therefore quickly in use: the implementation can start as soon as the machine is turned on. Technically once the parameters of the operation (speed, angle of projection, time of shot blasting...) are defined, the reproducibility is perfect.
Security
Shot Blasting is practically an operation without risk to the operators and presents no danger to the environment.
Cost efficiency
Shot blasting combines efficiency with cost control. Thanks to a good assessment of requirement and how to implement, the result obtained is without surprise. The surface preparation is uniform on the whole piece from the first treatment, thus avoiding waste and loss of time.
