Friction is the resistance to motion of one object moving relative to another. The generation of microscopic friction is the result of several mechanisms including the surface energy of the material itself.
As such, polymers have very low surface energy values when compared with metals by less than one order of magnitude, and therefore characterized by a low friction coefficient.
This feature makes polymeric materials excellent candidates for tribological applications...
Metal corrosion phenomenon of electro-chemical degradation is typical of metals which leads to the loss and detachment of material beginning with the surface, and above all to the loss of mechanical properties present.
In particularly severe operating environments, where the material comes in contact with certain chemicals and water, metal surface treatments are critical to shielding the surface from corrosive phenomena.
It is widely known that Additive Technologies comes with numerous advantages in industrial production processes, with their ability to integrate with traditional forming processes, and to create conceptual, functional prototypes and end-use parts, with reduced times and costs.
Freedom of design opens up the possibility to create small batches by immediately creating prototypes in order to optimize the performance of a given part, without the need for creating special molds, or...
Polymers are notable for their unmatched lightweight properties as a result of their density values ranging from 0.9 g / cm 3 and 1.3 g / cm3.
If we were to compare polymers to metals, lower mechanical properties would be clearly noted. As engineering polymers, such as those with carbon fiber Carbon PA (a carbon fiber reinforced polyamide) and super-polymers, such as PEEK, possess a high strength / weight ratio...
Fastening tools are fundamental devices used in cutting, machining and welding processes, with the aim of providing repeatability and accuracy while increasing productivity.
A key fastening tool feature is its ability to ensure interchangeability in the production process. Each fastening tool is designed to adapt to the geometry of the part to be fastened during the machining process.
With unlimited design possibilities, FFF technology can produce fastening tools to meet...
