Every system, treatment or component starts from a scientific approach that combines electro-thermal analysis<\/strong>, field experience and digital parameter control. Through proprietary calculation tools and monitoring systems, Aselt delivers repeatable results, lower energy costs and long-term reliability.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

FEM (Finite Element Method) simulation<\/strong> is a fundamental tool in Aselt’s design process.
Through three-dimensional analysis of the magnetic field and heat distribution, it is possible to predict the behaviour of the workpiece<\/strong> before the system or coil is even built.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Main benefits of FEM simulation:<\/strong><\/p>

  • Full visualisation of the magnetic field.<\/li>
  • Control of heating depth and surface temperature.<\/li>
  • Optimisation of power and frequency parameters.<\/li>
  • Reduced losses and uniform treatment.<\/li><\/ul>

    This phase makes it possible to move from calculation to production with real data<\/strong>,
    eliminating uncertainty and repeated testing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    \n\t\t\t\t\t\t\t\t\t

    During the design phase, Aselt uses coupled electro-thermal models <\/strong>to simultaneously study the magnetic field distribution and the thermal response of the treated material.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    This approach determines:<\/p>

    • The amount of heat generated at every point.<\/li>
    • The heating rate.<\/li>

      Application example:<\/strong> when hardening a crankshaft, simulation ensures a uniform temperature across the hardened area, avoiding overheating and internal stresses.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

      The efficiency of an induction heating system strongly depends on the coil geometry and magnetic flux distribution<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      \n\t\t\t\t
      \n\t\t\t\t\t\t\t\t\t

      Thanks to FEM simulation, Aselt can optimise:<\/p>

      • The shape of the windings.<\/li>
      • The positioning of magnetic flux concentrators.<\/li>
      • The gap between coil and workpiece.<\/li>
      • Power balancing across the active zones.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

        \n\t\t\t\t\t\t\t\t\t

        To maximise performance, high-efficiency materials are used, such as:<\/p>

        • Cu+Ag 0.1% copper<\/strong>, to reduce electrical losses.<\/li>
        • Fluxtrol\u00ae<\/strong>, to concentrate the magnetic field.<\/li>
        • Silicon nitride (Si\u2083N\u2084)<\/strong>, as mechanical and thermal insulation.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

          FEM technology is completed by the IPC process control<\/strong>, a system developed entirely by Aselt. While simulation predicts the ideal behaviour of the cycle, IPC monitors the actual parameters in real time<\/strong>: current, voltage and coil position.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

          Benefits of FEM + IPC integration:<\/strong><\/p>

            Aselt designs its systems with energy efficiency and environmental sustainability in mind. By optimising heating parameters and integrating heat recovery, energy consumption can be reduced by up to 30% compared with traditional processes<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
