Heat Welding Plastics

This heavy duty plastic welding kit has a hot air welding heating assembly that is temperature adjustable for welding plastics at various melting points.

Heat welding plastics. Cut the end of the plastic welding rod at a 60 angle. Plastic welding heat gun nozzles. The process invented in the mid 20 th century uses a stream of heated gas usually air to heat and melt both the thermoplastic substrate material and the thermoplastic welding rod. Plastic welding is the process of creating a molecular bond between two compatible thermoplastics polymer material that becomes pliable with heat and with sufficient temperature liquid.

Practice on scrap material before attempting to work on your project. Plastic welding is welding for semi finished plastic materials and is described in iso 472 as a process of uniting softened surfaces of materials generally with the aid of heat except solvent welding. Plastic welding is a process of uniting in a molecular bond two compatible thermoplastics generally with the aid of heat. Welding fast triangular welding nozzle welding welding nozzle swing welding plastic wel.

In other words thermoplastics a polymer plastic that can be melted and shaped several times are joined together by melting the surfaces and pressing them together. The substrate and the rod fuse to produce a weld figs. Welding of thermoplastics is accomplished in three sequential stages namely surface preparation application of heat and pressure and cooling. Rapid angular oscillations are applied to heat the plastic parts to be joined.

Insert plastic welding rod through a second opening in the nozzle. It is recommended that the welding rod be as long as the joint being welded. Use the plastic welder to form and bend plastic. This variation of the spin welding process is used for parts that are not symmetrical about an axis of rotation.

Hot gas welding is a fabrication process for thermoplastic materials. When cooled they return to a solid form. The heat in the extruded bead is sufficient to cause it to weld to the adjacent surfaces. Dry nonflammable wet surfaces.

It directs air to heat the rod and weld plastic. Install the welding tip on the heat gun.
