Hot plate welding is the process of joining two parts of a plastic component using heated plate. Plastic welding using hot plate method involves three sequential stages. Namely applying heat, pressure and cooling. The parts to be welded are pressed on preheated plate for predefined time for sufficient plastic material to melt. Then the heated plate is withdrawn and the slightly melted surface of two parts is pressed together to form a joint.
Hot Plate Welding Applications Hot plate welding has made it important in the building industry where it is used in the manufacture of UPVC door and window frames, which are made from extruded sections and welded at each corner. Other major industry using hot plate welding is the automotive sector. Automotive lamp assemblies, Battery casings, Air ducts & Tank filters. Domestic appliance components- Washing machine agitators & Soap dispensers. Water purifier cartridge, Pump bodies etc.
