Molecular projection
Molecular Spraying – Minilub
Molecular spraying is a high-tech process designed for the surface treatment of tools, preventing wear and solving demolding problems by reducing friction. This technology, first developed for space applications by NASA, has evolved into an advanced lubrication solution for the industrial sector.
Space Technology
NASA created a revolutionary surface lubrication technology, initially for its aerospace needs. In response to stringent performance requirements, this technology was adapted for industry to address friction challenges while reducing energy loss, extending cycle times, and reducing maintenance requirements. By controlling friction, this technology helps you improve your performance and increase your profits.
Application Process
The Minilub coating is applied at room temperature, propelled in a conditioned gas, and projected at high speed onto the target surface. This projection results in extremely strong molecular adhesion. Before applying the coating, the tool surface is carefully prepared to remove oxides and impurities, ensuring a structure free of unwanted elements. The Minilub coating is then projected and integrated into the atomic structure of the substrate, ensuring a long-lasting adhesion that can only be removed by abrasion.
