In the welding of plastics, two similar thermoplastic components are joined under heat and pressure. A dimensionally-stable and permanent bond arises after cooling.

Hotplate welding

Hotplate welding uses the radiant heat or contact of an electric heating element To join the plastic parts. This is the welding method that is most frequently used by G.W.P. A wide range of plastics, flexible and controllable process parameters and the option of complicated, three-dimensional joint surfaces make hotplate welding the preferred joining technique for particle-free, heavy-duty plastic joints. Hotplate welding produces weld seams that are absolutely tight, even for thin-walled components with complex geometries.

Advantages of Hot Plate Welding

• Suitable for many plastics
• Well-controlled process parameters
• For complex three-dimensional joint surfaces
• For thin-walled components
• High strength and a hermetically sealed welds
• Processing according to DIN 1910-3  

Other plastic welding methods

• Extrusion welding
• Ultrasonic welding
