Thermoplastic materials are used in a variety of applications, from food packaging to hardware fittings, and medical components to electronic parts. Aside from being versatile and affordable, these hard plastics are also popular because they can be welded when broken, leading to quick and cost-efficient repairs. Below are a few of the main techniques used for welding thermoplastic.

3 Welding Styles Applied to Thermoplastic

1. Friction

This process uses mechanical movement to generate heat and fuse two plastic materials together. One such technique is linear vibration where two parts are rubbed together in a linear motion, and the friction forces the ends to melt into one another. Friction is often used for welding plastics in the automotive industry, such as air intake manifolds and bumpers. 

2. Hot Gas

Hot gas uses an external heat source—in this case, a heat gun—to weld thermoplastic materials, such as PVC and fluoropolymers. The gun sends a stream of hot air to melt the joint of the plastic materials and the filler rod, which is made from the same polymer. Once these ends are soft, they can be fused. 

3. High-Frequency

High-frequency welding uses an electromagnetic field to fuse two plastic components. These are often plastic materials, such as polyurethane and PVC, that contain electrons. Electrical energy softens the molecules in both materials to generate heat and soften both ends. Pressure is placed on the materials to ensure a strong weld.
