Hot Plate Plastic Welding

Hot Plate Plastic Welding

Branson hot-plate plastic welding technology creates consistent high-pressure hermetic seals for a wide range of applications. 

Completed Shapes and Strong Seals

Hot plate plastic welding joins two or more complex geometric shapes, curved surfaces or internal walls. Available in horizontal and vertical orientations, Branson hot plate welding systems can cut production costs by eliminating glues, adhesives and other consumables. For precise control, models include a PLC with color touch screen HMI with interlocked doors to maximize operator safety.

How It Works

Hot Plate Welding

Hot Plate Welding is a joining solution that welds together virtually any shaped part, including those with contoured parting lines, internal walls and free-standing walls. Process advantages include difficult geometries can now be welded and helps eliminate consumables such as glues, solvents, and adhesives.  

The Process

Hot plate welding utilizes a heated platen with heat inserts that are cut to match the shape of the weld plane. The plastic parts that will be joined are pressed against the heated plate to melt and soften the entire joint interface. The plastic parts are then immediately pressed together to complete the weld.  Hot Plate Welding is a direct thermal contact process that creates a clean join.


Hot plate welding is frequently chosen for applications where hermetic seals, uniform weld flash or multiple parts per cycle are required. The flexibility of this process permits a wide latitude in designing parts.
