Automotive Door Panels Servo-Controlled Hot Rivet Welding

Working Principle of the Servo-Controlled Hot Rivet Welding Machine

The Servo-Controlled Hot Rivet Welding Machine operates using a temperature-regulated heating head to weld plastic components. During the welding process, the heating head is positioned above the workpiece requiring riveting.

As the workpiece is securely pressed against the heater, the plastic begins to melt. After a predetermined heating period, the surface plastic of the workpiece reaches the necessary melt level. Once heating ceases, pressure is maintained for a few seconds while air cooling is applied to solidify the molten plastic.

This process forms strong molecular bonds, achieving welding strength that surpasses that of the original material, thereby completing the entire welding operation effectively.
