Automated System for Gluing or Separating Modified Adhesives and Joining or Separating Plastic Materials Through the Use of Nanoparticles Sensitive to Electromagnetic Fields, on an Industrial Scale

An industrial process for gluing/joining at least two plastic components or substrates by means of at least one hot-melt thermoplastic adhesive modified by adding an effective amount of nano-magnetite nanoparticles, the process comprising:

• applying said at least one modified thermoplastic adhesive to a surface of a first one of said at least two plastic components on a desired gluing line(s) or point(s);
• laying the second one of said at least two plastic components over the first one in contact with the desired gluing line(s) or point(s);
• externally running a pancake coil-type electromagnetic inductor on the desired gluing line(s) or point(s), while conveying the electromagnetic radiation thereon until the desired fluidization or melting of said adhesive is obtained;
• at the same time, exerting a pressure on the second one of said at least two components until a uniform distribution of the fluidized or melted adhesive at the desired gluing locations is obtained;
• removing said magnetic inductor and cooling/letting cool said fluidized or melted adhesive to give a solid body stuck to both the first one and the second one of said at least two plastic components;
• repeating the above-described process in case it is desired gluing further plastic components to said at least two described components.
