Hot Plate welding is widely used for the most challenging materials and large part assembly with high strength and hermetic requirements. During the hot plate welding, both part halves are held rigidly in position against/near a thermally heated platen to melt the joining surfaces. The materials are then quickly separated from the heated source and driven together and allowed to re-solidify under pressure.
Hot Plate Welding Process Advantages
Ability to weld large parts and complex shapes and compound contours with little regard to part and joint geometry.
Can weld tall, thin, non-supported interior walls.
Highest joint strength of any weld process when welding PP,PE, TPE and EPDM materials.
Significantly smoother flash with less particulate than other assembly methods such as Vibration Welding.
Compatible with most thermoplastics.
High strength, hermetic welds are typical.
Multiple parts per cycle can be welded.
Easily automated.
Relatively low equipment cost.
Nature of the process is simple and highly forgiving of part tolerances when compared with other assembly processes.
