By raising the rate of development in industrial world, the opportunity to make mistakes will be less and less. So the importance of accurate design and working on the details are more BOLD! Also when you are developing a new product, specially when the cost of prototyping rises, there is no place for making mistakes. ARACo reduces the cost of research and development of a new product by emarkable experience in design and analysis. Using SOLIDWORKS and COSMOS simulation, we are able to predict the function of a machine or a structure under requiered conditions.
