In mirror welding, two plastic parts are welded together by fusion. The welding mirror heats up both sides of the plastic material, after which the mirror is removed and the two parts are forcefully pressed together. In the cooling process that follows the molecules of one part and the other form a single entity.

In mirror welding, no welding agent or welding wire is used. Mirror welding is suitable for welding plastic pipes as well as plastic sheets. Mirror welding is also known as stub welding. We use a specific stub-welding machine for pipe welding.

In extrusion welding, a heated welding wire is inserted between two plastic parts using a special plastic welding device, the welding extruder. Therefore, extrusion welding is a manual process and thus very similar to welding metals with a welding electrode.

The welding wire is of the same material as the 2 plastic parts to be welded together. For example, there are polyethylene and polypropylene welding wires. Extrusion welding is mainly used when welding special joints or in hard-to-reach places. Extrusion welding is true craftsmanship.

Extrusion welding is the preferred welding method when, for example, mirror welding is not possible. For non-standard constructions, special welds and hard-to-reach places, extrusion welding is a perfect solution for plastic welding.

There are 2 ways of welding plastics with a hair dryer. For small welds or repairs, often only the torch part is used, which melts the 2 plastic parts together by heating. We then refer to this as bonding, whereby 2 plastic parts are bonded together under light pressure without the addition of welding wire. An attachment nozzle is then fitted to the welding pen.

For a firmer weld, a welding nozzle is fitted that allows use of a welding wire. This welding wire consists of the same material as the plastic parts to be welded. Plastic welding with the special welding torch is suitable for all thermoplastics such as PE, LDPE, HDPE, PP and PVC.
