High Frequency Welding Machine

High Frequency Welding Machine only works with thermoplastics that have a high dielectric constant. In this process, an electric field is generated near the joint, the direction of which is alternated approximately twenty-seven million times a second. Every time the electric field changes, the dipole molecules of the polymer attempt to flip around to realign themselves to the new field orientation. Because this movement is impaired by inertia and friction, the molecules do not flip in unison. This constant relative movement of the molecules results in inter molecular friction which results in heat and, subsequently, melting. Radio Frequency welding typically has weld cycle times from two to five seconds and can handle parts from approximately one-thousandths inches thick to fifty-thousandths inches thick.
