Soldini, Argentina - (July 2007) - Scania the world wide leader in the manufacture of heavy vehicles, has recently installed in its plant in the province of Tucuman, Argentina, two new equipments of Shot Peening of last generation, totally designed and produced by Cym Materiales SA. Since the year 1987 the company Scania Argentina has been performing a shot peening process to all its gear boxes. This Shotblasting process generates compression tensions on the surface of the root of the gear’s teeth and pinions with the object of increasing in 20% the fatigue breaking resistance. In the last few years, and with the new demands for quality, Scania has had the need of improving the shot peening process that it had been performing, to cover the new requirements that its gear boxes have to comply with. Thus they decided to update their equipment changing to a new double shot peening process that combines the effects of the conventional shot peening with a second shot peening performed with less intensity. With this new process Scania has achieved to increase 30% the fatigue breaking resistance of their parts.
The equipments developed by Cym Materiales SA totally comply with the strict quality standards required by Scania.
