In the welding of plastics, two similar thermoplastic components are joined under heat and pressure. A dimensionally-stable and permanent bond arises after cooling.
With extrusion welding, an extruded filler material consisting of a plastic similar to the component is used to join the joint surfaces. The extruded material is applied with a molding shoe to the joint surfaces heated with hot air and then pressed. G.W.P. uses extrusion welding as a manual welding procedure to join plastic components with thick walls. The advantages of hot gas extrusion welding are very high strength and high weld seam quality.
Advantages of Extrusion Welding
- For parts with wall thicknesses up to 30mm
- Very high strength of the weld
- Low residual stress
- Processing according to DIN 1910-3
