Portal elements for positioning and mounting systems

摘要

Positioning arms (1) for positioning and assembling systems are subjected to high accelerations and must therefore be designed so as to be lightweight but resistant to bending and twisting. Positioning arms (1) which are lightweight although very resistant can be obtained through the use of composite materials made of metallic or ceramic foams and non expanded materials for positioning arms (1) in positioning and assembling systems. Semi-finished products (5) are placed in a non expanded material where linking between the semi-finished product (5) and the material (1) is better than in the metallic or ceramic foam.
